HPI RS4 Pro 4 Forum

[GuyIsDamGood]

Hey Pro 4 guys. I`ve just joined your group. I`ve purchased a Pro 4 and I like how it looks(it looks like it wants to run fast on the track).

I haven`t ran it yet; but it should run alright.

Take Care.

[twism86]

Hey, just got one too, got it off ebay prebuilt, so i have a question for you if you built your from a kit. How do you take off the shock caps b/c as i see it they are round so do they screw off? Also is it ok is they spin w/ the rest of the shock? Thanks

[thundershot]

GuyIsDamGood - So you sold your imaginary tbevo4? Tired of spamming at the tbevo4 thread now you're here. Hehe. So does your tt01 smoke the pro 4 like it did the tbevo4? Answer twism86 question or do you have to google it to find out.

[GuyIsDamGood]

Hey twism86; if the Shock Cap is totally spinning with the shock when you adjust the Shock Spring Adjust Nut then that`s no good.
-Take the Shock off and tighten the Shock Cap.....(the Shock Caps screws on and off).
--Each Shock is held in place on the chassis by 2 screws(1-top and 1-bottom), 2 nuts(top) and 2 little plastic ball things(1-top and 1-bottom).

I hope this info helps.


Anyone put a Ball Diff in the front of their Pro 4? I don`t care too much for 1-Ways; I like Full Braking.



Hey thundershot(Broke Guy); get some money and Hop-Up your TT-01. You`ll like it better that way. . . . .But; I`ll tell you and everone else how the Pro 4 runs on the track.
-Do you have a Pro 4? If you do; you can help me/us out on a few things. . . . .(If you Have Respect for people(Me); there`s No Hard Feelings.)

Take Care.

[thundershot]

Its hard to respect you when you keep putting down other people's rc and saying your tt01 blows them away. Have you reread your own posts at the tbevo4 thread? They are ridiculous considering you dont know much about the tbevo4 let alone own a real one. Is the pro4 your new imaginary kit? :D

[macchia7o]

Hi All

Im a newbie in RC world. About 2 weeks ago I bought this kit and have several questions to ask. Ok honestly I never play RC before, this is my first RC ever to build. And I just totally have no idea what are the use of each parts. To start, what is one-way or 2 way? I've been reading all posts on this Pro4 forum and many of them talking about "one-way". Where is it located? I know it sounds stupid but i have to ask this question so I can learn. And will have lots of question to ask in the future. Thx.

[microrcdude]

The one-way is just a differential, its what connects the main drive-shaft to each wheels axle. There is really no need for a one-way if you plan to just drive the car around your neighborhood, but if you plan to get heavy in racing, it might not be a bad idea to pick one up in the near future

[macchia7o]

Owh no no no. Of course im planning to race in the future. If im just bashing of in neighborhood, i will not buy Pro4. So basically its like 2WD and 4WD? What "way" is the standard Pro4 has? Thx for your reply anyway.

[GuyIsDamGood]

Thunderdope; just Stop. . . . .You`re Broke; you shouldn`t be into R.C. Cars.
-I`m waiting for you to Hop-Up your TT-01. Do that 1st; then you can talk to me.

Anyway;.....Hey macchia7o. A 1-Way is a Differential that is mostly used in the Front of a kit. It will still give your car/kit 4WD. It gives the car/kit better steering on tight turns.
microrcdude is right; a Front 1-Way isn`t really for Street Driving.....It will help in a little Street Racing and Track Racing.
But you can practice running your car/kit with a Front 1-Way and you will begin to drive it with no problems.
- -The HPI Pro 4 has a Front 1-Way and a Rear Ball Diff.

The Pro 4 runs well. It ran Faster laps over My TT-01(2.5 seconds) and TB Evo 4(1 second).-(All using the same Electronics.....and Peak Dynasty 19-Turn Motors.)
It has less Understeer than the other cars/kits.

Take Care.

[thundershot]

Sorry Guy but I'm not broke but I'm not pretending to have kits like you. I only have one rc and that's an xray. :D
2.5 sec shaved off from the tt01 to your new imaginary pro4, that's weak. Stick with your real car, the tt01 ms(short for Mine's Stupid) and stop embarassing yourself.

[GuyIsDamGood]

Enough.

[GuyIsDamGood]

Thunderdope; This is My Last time I`ll say something to you.....You Don`t have an XRay kit.....I remember you said you only have a TT-01.....? You`re too Broke(poor) to afford a total kit(you can even get Hop-Ups).....Get A JOB.....You`re on a Library Computer; your time is Out. You don`t offer any advice in any of the kit topics/threads. You Don`t have any R.C. Cars. You waste your time talking wack crap to me; making a jerk out of yourself.....everyone sees it..........You`re a Dope, Get a Girl or Play with Yourself.

The only XRay he has/got is when he Broke his arms and legs and went to the Hospital. . . . .You`re Finished.....You can`t Beat That.

-thunderdope; you better not be from N.Y.C. If you are.....Meet Me At the Track on Father`s Day. Pennsylvania Ave - Livonia Ave in Brooklyn. . . . .Bring your Xray(s).

-I`m Done.....Ha Ha!

[thundershot]

I never said that the tt01 is a crappy kit. I was trying to solve its problems before and thought, why stick with it like you and make it a tt01 ms(short for mine's stupid) and spend all that money? So I bought an xray instead. :P
Now I'd like you to post your dumb comments about your tto1 being better than your imaginary tbevo4 in a racing forum like rctech and see how they'd laugh at you so much I'm gonna cry. Haha! You must really suck if you have nearly the same lap times with your kits. Even in your imagination you suck. Haha.
I asked you to post some pics of your imaginary tbevo4 before but you said you dont have a camera. Funny, for some one with a tbev04, tbevo4ms, hpi pro4, tt01 ms(mine's stupid), you must be very rich but can't afford a camera?
Your credibility is down the drain. So stop touting your tto1 ms to be as good as a world class racer like a tbevo4 or hpi pro4 because it just makes you sound dumber and dumber.
Again, read this guys comments on the tbevo4 thread as he thrashes the tbevo4 when he doesn't even have one.

[macchia7o]

To "GuyIsDamGood" and microdude

Thx a lot for the reply eh, now I understand.

[macchia7o]

Hello again. I just finished building up my Pro4 kit. Oh it was so much fun. I noticed that I have quite a lot of left up parts, is it normal? There are some of the plastic parts and I have unused screws. I just worried if I forgot to put it somewhere in the kit. Did you guys also have some parts left over when you finished building the kit? Thx in advance.

[GuyIsDamGood]

Hey macchia7o; you sould only have these parts left over:.....(unless your box(Pro 4 kit) gave you Extra parts)
-3 Front Caster Block Sets
-1 Droop Set-Up thing
-2 Servo Arms
-1 Servo Saver Part
-A few Ball Cups
-A few Shock Pistons
-1 or 2 Screws should be unused(extras)

That`s what I have left-over from My box(Pro 4 kit).

You should take another look at the Manual and your Pro 4 to see what you over-looked.

Take Care.

[GuyIsDamGood]

My Pro 4 won`t go totally straight. It will go Left and/or Right when I`m on and off the throttle.....(I`ve installed a 23-Turn Tamiya Super Stock TZ Motor in My Pro 4 and still My TT-01 goes straighter with a 13-Turn Reedy Worlds Edition Motor.....Ha Ha!).
I had to adjust a few parts just to get it to run straighter(85% better).
-----Working the Steering Trims didn`t/doesn`t work much. . . . .So.....
-I installed a New servo.
-I thought it was the Ball Diff; so I loosened it a bit.....(just a little straighter).
-I tightened the Servo Saver.....(straighter).
-I Lowered the Front-Left Shock and Raised the Front-Right Shock.....(Straighter).
-I gave it Front Toe-In of 1-1/2(1.5)-Degrees.....(Much Straighter).

(I use Tamiya Medium(Yellow) Shocks on My Pro 4.)

Anyone else had/has this problem with their Pro 4? If any; can you please tell me how you fixed it.

Thanks

Take Care.

[GuyIsDamGood]

I`ve looked-up some info on the Pro 4 online and found out the Pro 4 just can`t go Straight(info from: X-Streme R.C. Cars). . . . .I`ve thought I`ve did something wrong with the kit.....Wow.....I`m glad it`s Not My Set-Up.....Ha Ha!(for now).

I might have slowed My Pro 4 down by doing some adjustments.....?.....But it goes Straighter.....Ha Ha!

But overall; did/do any of you other Pro 4 Guys have the same problem?

Thanks

Take Care.

[GuyIsDamGood]

I`ve got My Pro 4 going much more Straighter(basically perfect). I had to reset every Steering Turnbuckle(all 3) and I`ve put in a Peak Dynasty Motor(the Tamiya Super Stock TZ Motor just had to go). But I think the part that made the difference is the Tires.
-I was using a semi-used set of Tamiya Racing Slick Tires and they was making the car slide and turn all over the track/street.
-Now I put on a set of HPI Belted Racing Slick Tires and it runs better.


Where are you other Pro 4 guys? I`ve been up here putting info by myself for the last 3 Weeks. There has to be a few people out here still running the Pro 4.....?

Take Care.

[pyro18t]

Say what ever happened to the 1/12th scale 4wds? I LOVED the mini, and would pick one up in a heart beat, but I'm kinda scared to because of the lack of parts?

I looked for the mini on here but there isn't even a forum for it!

I think I might just have to settle for the next best thing a RS4, but I don't think I'm going to go pro, I just bought a xxx-4 G+ so my wallet is hurting

[GuyIsDamGood]

The Pro 4 is a good car/kit. It`s really fast. But; if you`re going to get it.....dump out the Front 1-Way. -It doesn`t make the car run to it`s best.
-Get a Front Solid Axle or put a Ball Diff in the Front.

Take Care.

[pyro18t]

do they make a non-pro kit, like a RS4 - 4 sport or something, like I said I just want a competitive on-road car that I can hop-up slowly, intsead of diving in with both feet

[GuyIsDamGood]

I think HPI makes a Sport Kit/Car. I think it`s discontinued. But you know you can find a few at a few places.

The Pro 4 is a good kit/car and it isn`t high priced. I got My Pro 4 for $265.00(I saved $35.00) at a cool hobby shop(105 St. Hobby Shop in Queens). I don`t use a (so called) top radio to run it(My Kids killed My 3PK); I use a 2P(for now) and it runs well.

Take Care.

[pyro18t]

Well I got 1 1/2 xxx-s G+'s coming to me, this kinda works out good because I have a xxx-4 G+ and the cars are similar in design, so I don't have to completely learn a new car.

Jay

[GuyIsDamGood]

What is a xxx-s G+`s and a xxx-4 G+?

Think about getting a Pro 4; it`s a good kit/car.

Take Care.

[pyro18t]

What is a xxx-s G+`s and a xxx-4 G+?

Team Losi XXX-S graphite Plus is a 4wd single belt touring car
Team Losi XXX-4 graphite Plus is a 4wd single belt buggy (one of the top 3 4wd buggies to date as far a wins)

they share simialr chassis, and drivetrain so I picked up a XXX-S G+ from TSR6 on here should have it in about 2 weeks.

Jay

[GuyIsDamGood]

Alright; sounds cool. . . . .But Now you should hang-out in the Team Losi XXX-S and XXX-4 spots(if you don`t already).....I want to talk about the Pro 4.
-I don`t know much about Team Losi kits/cars(the JRX-S looks like a good kit/car) and I Don`t like Trucks or Buggies.

So-far there`s no one that is talking about the Pro 4 out here.....Why?

If you have room; get a Pro 4.....I`m getting lonely here.....Ha Ha!

Take Care.

[pyro18t]

I would love to get a RS4 pro 4 but it's to pricey right now... maybe some day I'll get one.

Jay

[GuyIsDamGood]

I understand. The gas prices is killing me(in New York City it`s $3.22 per gallon - regular).....It`s taking a few $ from my R.C. Cars.....Ha Ha!

-See if a local Hobby Shop is selling a Pro 4 for a little less then regular price.


By the way I ran against a Hot Bodies Cyclone with My Pro 4.....I killed the Cyclone(we were both using 19-Turn Motors).
-The Pro 4 runs (better)just as good as the Cyclone.

Take Care.

[jamstan]

I bought a prebuilt Pro4 chassis off Ebay and after putting the electronics in when i run it in forward only the front wheels turn and in reverse the front and rear turn in opposite directions?? is it possible the guy who built it put the readend in backwards or? Probably a simple fix but i'm an ignorant newbie--thanks~Stan

[losiguy1090]

Sounds like he might have put the diffs in backwards. Might just be the one-way thats in backwards.

[bxpitbull]

Guyisdamgood-whats up black? Here in NYC as well. You roasted that other cat (thundercat or whatever). YUK YUK. In any event, I just got my Hara Pro 4 a little over a week ago and I have one recurring problem. Outside of shredding my ball diff (it was installed in the rear of the car), I am snapping mad pins and shredding the hole where the pin is inserted to meet the swivel of the axle.Now, I am running a much more powerful jump-off than a 19t and I see this could be the culprit. What can I say, I like speed. Is there a company out there that makes universals for the Pro 4. Coincidentally, I used the bones from (blue) from some old CVD's from when I owned a TC3 (the bones are the same, the axles are shorter and different thread on the TC3). These bones appear to hold up but I know its a matter of time. I tried to use universals from a Pro 2 I had lying around, but the axle shaft is like a 1/4" too short. turn signal...Too all those looking for maximum speed, if you havent done so, INVEST IN THE NOVAK GTB with the 4.5 VELOCITI! Peak out your cells (nothing less than 3300) and the run time is tremendous. At 90.8v peak, charged at 4.5 amps and 40mv, I am getting 12-16 minutes run time! And thats full blast! Str8 smoking cats. Thing is flat out flying. Final drive of 9.95 (98/24 gearing). If I dont peak it out, and go with a normal 8.54v full charge, a measely 7 minutes run time. The power is just sick sick sick!!!!! Turn signal...back to the orignal topic, what can I do to counter the pin snapping and hole shredding? I run a spool in the back and looking to jettison this one for a ball diff. If I am shedding metal, I know I will tear the delrin and composite outdrives out of the frame. Any help would be appreciated. Turn signal...Guy, I am in Brooklym too. Where is a good spot to get some burn,other than floyd bennet field. I run my Savage and Pro 4 on weekends, but finding spots to get good burn with both in NYC is a task.

[GuyIsDamGood]

Hey Jamstan; losiguy is right. It`s most likely the Diff.
But at 1st My Pro 4 was giving me problems keeping a straight line. -It would go left and right(it was killing me). -I fixed the problem by giving it 1-Degree of Front Toe-In and I had to straighten out the Steering Link so the wheels center with the Radio.
I runs good/well now.


Hey bxpitbull; those Pro 4 Ball Diffs are weak.....you can kill them fast. But you say you`re also killing the MIP CVDs(I thought those are the strongest out there). -You said you`re running with a Spool(Solid Axle) in the Rear and a powerfull Motor. . . . .That could be the reason you`re killing those MIP CVDs. You have too much power for them to hold-up.
-You`ll have the kit longer if you put the Spool in the Front and keep the Ball Diff(not too loose or tight) in the rear. -You won`t(you shouldn`t) kill the Outdrives if you use Slick tires.

The Pro 4 isn`t built for Straight - Speed - Bashing. It`s a regular Top Of The Line Pro Racer. Drive - Race and Relax type of kit/car.


There aren`t too many places to run/race Electric On-Road in N.Y.C. I/We had a Track in East N.Y.(P.S. 13 -- Pennsylvania - Livonia); but the school and the police doesn`t want the yard open this Summer.
I`ve heard they do some Racing in Highland Park(Tennis Court area) in East N.Y. I haven`t been there yet; but I`ve heard it`s not so bad.
-I realize I`m not really ready to race yet(getting My Kit/Cars Fully Hopped-Up); so I`m not missing much yet.

I`m/We`re planning on setting-up a track in a school yard on Pitkin - Hemlock(in East N.Y.). It`s not too big; but it might be good enough for 19-Turn. . . . .We`ll see.

Thanks.....That guy thunderdope(thundershot) just started with me for No Reason. I don`t start trouble; I just want to Live, Help Good People and Take Care of My Family.

Nah nah. I'm not running as a dragster. Practicing in fron of my place, setting up cones and the like. Considering there isnt a track in NYC, I run on smooth blacktop. Race and Relax type of kit/car, no such animal. Have youseen how Atsushi Hara rips with his car? He runs a 7 turn double in modified, so I know the car can hande stress. Unless he is changing parts after every heat. Thats a thought. Turn signal...spool in the front is no good because your turn radius is almost zilch. The car at speeds will turn like a bus. one-way all the way. Turn signal....19T is too mild for me, raced that and while you have to have good judging and driving skills, someone with a tweaked out car usually abandons the pack and leaves the remnants battling for the remaining spots.
But, considering I did ask, if you cats come up with a track, I will drop a 19turn in to get me some burn with some real racers.

It's good to see a grown ass man shut down a big mouth kid without becoming an "internet tough guy". Now mind you, I talk mad ish on the track, so if your joing aint "bout it bout it", I will clown dat azz. LMAO. Seriously though, I spoke with the cats over at HPI and they said that there are some plans to come out with strengthed dogbones and possibly universals if the demand continues to escalate. Holla back. One.

[GuyIsDamGood]

Hey bxpitbull; yes...I/We plan on Setting-Up a Track in the school yard over at Pitkin - Hemlock.....(I don`t like to drag - race either.....but I will race/run a few 2-Fast Too Furious Loops.....Ha Ha!).
-The yard has a smooth surface(fresh asphalt). I/We sweep it good; then set it up.
- -We have fun when we race. We talk junk also.....that`s part of the fun. Now when someone is always Crashing into our cars. . . . .We don`t play with that.
-I`ll tell you when we`re setting-up the track at the school yard. . . . .It will be on Weekday Afternoons at 5p.m. until Sundown.

Remember the team racers don`t have to pay for their parts; so they don`t care too much about breaking something.
-But you have a point...Hara does(has) run 9 and 7-Turn Motors in his Pro 4 and there was no heard-of damage.
-Those MIP CVDs are still the strongest I`ve seen. I have Tamiya kits and their Universals aren`t stronger than MIP`s.

I`ve never used the Spool(Solid Axle).....yet. The 1-Way is alright; but I like to drive the car; so I installed a Ball Diff in the Front(I like brakes).
-I`ve ran with 13 and 10-Turn Motors(Reedy Ti Worlds Edition) in my Pro 4(only to teach the Nitro Guys some Electric Speed.....Ha Ha). The faster motors would kill the Ball Diff(s); so I just called it My 19-Turn Car.

Take Care.

[bxpitbull]

When you guys build the track, you have to hit me up. I travel with a trunk full of vehicles ready for action and there are some people with power ready to compete, I'll be there.

[GuyIsDamGood]

Alright bxpitbull; sounds like you`re Ready to Race.

I don`t run My R.C. Cars on Hot Days(above 85-Degrees).....I don`t like Summer/the hot weather.
-I/We run/race against Nitro Guys also; since there`s not many Electric Guys out there. - - - - -No Transponders.
-We usually run 19-Turn, 13-Turn and sometimes 10-Turn.

I use the Peak/Orion - Dynasty/Element Motors(19-Turn) and Reedy Ti Worlds Edition 13-Turn and 10-Turn Motors.


Since you have a Pro 4(and if you like Hop-Ups?.....I Do); you might want to know about the Aluminun Camber Plate I`ve seen at the HPI Europe site. I have the HPI -Pro 4- Carbon/Graphite Camber Plate(s) - Item # 73085.
-The Carbon/Graphite Plate(s) look good; but the Purple Aluminun Plates make the kit look brighter. . . . .Well it`s too late for me; I`m good with the Carbon/Graphite Plates.

There`s not too many Hop-Ups for the Pro 4.....that`s somewhat good.

Take Care.

[bxpitbull]

Um, people, my Pro 4 thread is looking a bit anorexic...what it do?!?!?

[speed6]

Hey guys do you know a good setup to convert my Pro 4 to a drfit car ?

Thanks for looking

[GuyIsDamGood]

Hey bxpitbull; what Thread are you talking about.....the Shocks.....I need more info in your question.

That Heat Wave we had 2 weeks ago killed me. It kept me from running My R.C. Cars. The weather is cooler now; so I might do a little Street Racing.

-Is there any more NEW Hop-Ups for the Pro 4(to brighten it up). It looks somewhat Flat compared to the Tamiya TB Evo 4 and 5..........(I might get it; but it would be a waste of money because it`s basically the same as the Pro 4).


Hey speed6; sorry.....I`m not into Drifting so I can`t help you on it. But; I think I do a few drifts when I take a fast turn.....?

Take Care.

[bxpitbull]

Convo was real good then people faded into oblivion. I was two seconds from selling my car. The rear diff just cant take the 4.5. Came up with a solution that mayt work but, considering it is the best HPI (not Hot Bodies) has to offer right now, I will work with it. Getting ready to buy another one (used) for parts and will really make a go of it. Turn signal....the diffs from the Pro 2 are the almost the same size. The shorter outdrive is the same exact size, but metal. Figure I will use that one for one side, and the graphite for the other. Seems to be more durable and should be able to withstand the torque. Diff had me so aggy, I actually raced with the GTB/4.5 set-up in my TC3 :eek: . Turn signal....whats been going on?

[GuyIsDamGood]

Hey bxpitbull; I told you the Pro 4 is just a Top of the Line Racer.....Drive - Race and Relax.....Ha Ha!
I don`t run/race My Pro 4 too hard. My Pro 4 is somewhat of a Classic Kit(shelf ready); I don`t want to mess it up.


My Pro 4(Hara) is now fully Hopped - Up. I just got the Carbon/Graphite Bumper Brace; I`m done with it.....for now.....there`s no more HPI Hop - Ups for the Pro 4.


I haven`t raced My Cars in a while. I/we are/were planning to go to Floyd Bennet and see what that track looks like and do some fun racing(weekdays if any).

My Pro 4 is ready to destroy! I bought a used Pro 4 from this cat "NEWRACER"..dude can make some diffs! I took my concoction out, put one of his diffs in and the car is ballistic with zero slip problems. Looks like he used the Associated thrust kit, but so what! The car is holding it down and nitro cats at the field better be easy when I get my Li-Po cells. Will catch you at the track in the upcoming weeks. I will be the cat with the HPI package...micro RS4 hopped up w/mamba, Savage hopped up w/picco .28, Nitro RS4 3 hopped up w/OS .18 and Hara Pro 4 with the GTB/4.5. Damn, no wonder I can't pay my Con ed on time. :eek: :D

[microrcdude]

hey uh....ill store your cars for free....hehe nice collection man. Any pics of all the chassis together?

[bxpitbull]

Good Birthday microdude...mine is the same

[GuyIsDamGood]

Hey bxpitbull; you should have fun at the new track at Floyd Bennet. But I`ve heard they don`t race Electric too much over there. I just plan on taking 1 or 2 cars down there and drive them on the track(if possible).

On the Brushless topic:
-I`ve read in R.C. Car Action that Brushless Motors kill Transmissions(Gears) in Electric Cars.
--You`ll be killing a few Diffs with that Brushless Power you have.....Ha Ha!.....(I know you like the speed).

I was planning on getting a Novak Brushless System; but the Power of the Reedy Ti Worlds Edition Motors changed my mind.(They aren`t as fast as Brushless; but they`re Fast.)
I use 10 and 13-Turn Motors.....(safe speeds).


I need info on a Aluminum Motor Heat - Sink for the Pro 4. . . . .Is there any?

Thanks

Take Care.

[bxpitbull]

Ever since NEWRACER sold me a Pro 4, I have had zero diff problems. I DID however blow a 4.5. The Kevlar wrapping inside the motor and magnet had a clash of the titans and the motor died. Novak will be replacing it AND I bought a new one in the interim to have a backup. Brushless is sick.

As far as Floyd Bennet, when I go Li-Po, the nitro cats will have to fallback and play their position. Considering I am getting 10 minutes per pack (IB3800), I look forward to this run time to increase once I go Li-Po. I have seen cats go damn near an hour with cells from Maxamps and Apogee. Once my kids are in school and all of their school needs are out of the way, Li-Po here I come.

As far as blowing the 4.5, the cats over at Novak told me that that is a rarity. And for me, small drop in the bucket as long as it doesnt happen on the regular. But, considering I have blown nylon on brushed armatures, am tired of cutting comms and replacing brushes, I'll take brushless any day over brushed. The torque, run time and speed does it for me....

As far as heat sinks, I run this on my motor..

http://www.rcmart.com/catalog/product_info.php?cPath=421_293_32&products_id=11791

Mine is the aluminum colored one, and I run several things to keep my heat in check:

Several small but ideally located holes in the body to assist with venhilation.
A nitro on-board venom temp gauge with the wire wrapped around the motor itself with the heatsink clamped on top to get the most accurate temp readings.
Fan on the speed control...of course.
Maximum cut-out on the rear of the body.

My motor (before it blew :( ) never saw more than 128 degrees. ESC, never broke 105 and the batteries, they hit 150 but amp draw will do that. I'll post pics when I install my new motor so you can get an idea of what I am talking about. Not like I re-invented the wheel, but, seeing that I run nitro cars and trucks as well, I totally am hooked on keeping things cool.

[bxpitbull]

You know, I just snapped some pics of my main vehicles and didnt even think to upload them. Will take care of that in the upcoming days. I totally tanked on that one. Took the pics and didnt even post em. Store em for me? If you live in NYC and I can just walk in to your house at 2 am when I like to get my pratice burn, sure, store away.

Hey bxpitbull; Thanks for the info. -That Aluminum Motor Heat-Sink looks cool. . . . .But it would look Better if it was in HPI - Purple.
-I would really like to have a Purple Motor Heat-Sink.
- -I think the Pro 4 just needs a Purple Aluminum Motor Heat-Sink and it would be complete.
- - -I don`t know why HPI doesn`t make an Aluminum Motor Heat-Sink for their Electric Kits.....?

I`ve checked - out that link to Dinball - RC-Mart and found out there are Purple Aluminum Motor Heat-Sinks out there. . . . .In Hong Kong.....Ha Ha! I`ll have problems getting stuff from there. I/we know NO Hobby Shop has anything like that out here.....(Shame).

-Does those Purple Heat-Sinks match the HPI Purple? I would really like to get the EXCEL Purple Heat-Sink.

Thanks

Take Care.

[bxpitbull]

Dinball gets your stuff to you rather quickly. I have ordered from them and have received my stuff in 7-10 days. I just ordered this:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=6051669731&rd=1&sspagename=STRK%3AMEWN%3AIT&rd=1

Figured the black will go with the Pro 4 black carbon fiber chassis. Form and function work for me.

[GuyIsDamGood]

You`re right; Dinball - RC-Mart does get stuff to you fast. I`ve ordered some Tamiya Parts from them in October 2004 and I recieved it in 5-Days.

I`ve seen an Integy Aluminum Motor Heat-Sink but it was in Silver.
-I`ve also seen an Integy Purple Motor Heat-Sink but it was part of a Fan Unit(I don`t want a Fan Unit).
-I just want a Nice Purple Motor Heat-Sink.

Thanks

Take Care.

[GuyIsDamGood]

The Ball Diffs(Front -or- Rear) loosened.....(I removed the Front 1-Way and installed a Ball Diff.) I had to tighten both diffs. Now it runs better than before.

Those Ball Diffs aren`t made to stay set for too long.

Take Care.

[GuyIsDamGood]

I have the Pro 4 Hara Edition and I feel there is no better Shaft Drive kit out there.
So; there`s no reason to get(make) another Shaft Drive kit.
-Tamiya has a TB Evo 5 out and it`s the lastest Shaft Drive kit; but it has the same features as the Pro 4.

But Tamiya made the TB Evo 5 brighter than HPI`s Pro 4; that`s what makes it look so nice.


To HPI:

-Please make some Purple Aluminum Rear Uprights, Purple Aluminum Motor Heat-Sink and Purple Aluminum Steering Posts.

- - - - -Thank You


Take Care.

[mr lee]

I see that the Pro4 and Hara have been moved into the "discontinued" section on the HPI web site!!! ***!!

So what's next?

[GuyIsDamGood]

Hey mr lee; I was just going to put that info down today(you beat me to it).
-HPI discontinued the Pro 4 and Pro 4 Hara Edition kits. . . . .I guess HPI -/- Hot Bodies are totally into the Cyclone(s) now.
-HPI might come out with a Pro 5. . . . .I don`t think they can make it any better than the Pro 4(it might be Belt Drive); but we`ll see.

Keep your Pro 4 in a safe place. It`s now a Classic Kit.

Take Care.

[mr lee]

Have only had mine for a year!!!! Now it's no longer available!! Oh well will have to try something else when I feel the need! Parts supply should still be ok for a couple of years as there are tones of Pro 4's in the world.

Mine only comes out on race days so it still looks new :)

[graeme_rsa]

-HPI might come out with a Pro 5. . . . .I don`t think they can make it any better than the Pro 4(it might be Belt Drive); but we`ll see.


Also discovered that HPI had discontinued the Pro4 when I went looking on their site for Pro4 parts! OK the Cyclone seems to be the tops at present but it is competing under the Hot Bodies make and not HPI (OK I know that Hot Bodies is owned/AKA by/as HPI but it's not the same as saying HPI have won XXX championships this year) - on the otherhand perhaps their descision to drop the Pro4 was because they were being beaten all the time by the Cyclone!

The Pro5? A Cyclone made by HPI in what colour anodising ... green :)?

I still think it is all hype! Mr X (Factory Driver) won the Y championship using a Cyclone (provided by HPI/Hot Bodies) ... Mr X would probably have won the Y championship driving a HPI Pro2!
It's all arranged so that the HPI faithful will dump their Pro4's and all go out and buy the very expensive Cyclone!

Cheers

Graeme

[GuyIsDamGood]

Hey graeme_rsa: what you said is somewhat right. They do want Pro 4 owners to buy the Cyclone. But the Cyclone Hara Edition is discontinued also. Yes; HPI and Hot Bodies has problems.
-I explained it on the RCTech site.


It feels funny that you now own a Kit that is Discontinued. It gives you that left-out feeling.....Ha Ha!
-But; you now own a Classic R.C. Kit/Car.

I will never buy a Hot Bodies kit.

Take Care.

-Tamiya has a TB Evo 5 out and it`s the lastest Shaft Drive kit; but it has the same features as the Pro 4.

Having put my Pro 4 side to side with an Evo 5 I can tell you there's a few noticeable differences just from a quick glance. The upper deck is several mm lower (about 7mm), the diff carriers are alloy and are open (not too keen on that to be honest). The all alloy steering is quite pretty too but whether it's any better is up to the driver although there must be a reason the TRF415 MRE uses it.

[graeme_rsa]

Hi

Regarding the difference between the Cyclone and the Pro 4, I have now heard from two 'expert' sources some comments regarding them!

From the top SA racer - use the Cyclone in Modified but the Pro 4 in stock 27!

From a UK retailer's site

We don't recommend a motor lower than 17 turns in a shaft driven car (they tend to overheat the gears) but many get away with it. Belt driven cars are able to take a higher power motor with less risk of damage to the gearing.


Comments?

Cheers

Graeme

[GuyIsDamGood]

Hey MisterBurns; what you`ve said is right. The Tamiya TB Evo 5 has a few features that aren`t on the Pro 4(somewhat better access to the Diffs and more aluminum parts. . . . .The TB Evo 5 has open Diffs?.....Somewhat like a Belt Drive Kit?.....Why?.....If so; that wouldn`t be too good.). But; overall the TB Evo 5 is the same as the Pro 4.
-I like Tamiya Electric Kits/Cars. I`ve had a TB Evo 4(I killed it 2 weeks ago); it was a tough kit. I plan on getting a TB Evo 5.


Hey graeme_rsa; I don`t know about that. I run a 13-Turn Reedy Ti Worlds Edition Motor in My Tamiya TT-01 and TB Evo 4 and it haven`t gave me any real gear problems. But the Tamiya Pinions will show some wear after about 11 Runs.

I think the R.C. Car Companies want us to use Belt Drive Kits/Cars.
-Think about it: the only NEW Shaft Drive Kits out there are Tamiya`s TB Evo 5 and Kyosho`s TF-5. Everyone else is totally going Belt Drive.

I only like Electric Shaft Drive Kits/Cars; so I wouldn`t really know about how a Belt Drive Kit/Car runs.....(The last(and only) Belt Drive Kit/Car I`ve ran was a Tamiya TRF TA-04; and that kit wasn`t built like the new Belt Drive style. So I`m a little out of touch with Belt Drive Kits/Cars.)

Take Care.

Hey Pitbull - welcome back - you didn't miss much!:)

Why were you banned?

Looks like this thread is as dead as the Pro 4!

A couple of months now and no postings! Has everyone given up on the Pro4?

Also no news from HPI as to what they are doing on the 1/10th electric circuit! Have they packed it in and given it to AE / XRAY / YOKOMO / HOT BODIES?

Or - as it is winter in the Northern Hemisphere they are waiting until spring to bring out a new car?

In RC Car Action I've noticed that HPI have been very quiet lately on electric - is this a sign that they intend going the route Ofna went several years back and just drop the electric side altogether?

No idea why I was banned. Wasnt flaming or arguing, just logged in one day and poof, found out I was banned.

I wonder what the folks over at HPI are doing. They are coming out with a nice stadium truck that seems it'll have some racing potential. The wheely king looks like a fun toy.

Really hope they dont give up electric...or racing for that matter. The whole micro rs4 rebirth is getting a little stale. Tamiya proved that torque steer can be beat with the EVO V, so HPI should do take some advice fromthe GEICO caveman and "do a little uhrrh.... research!".

[mr lee]

I just bought me another Pro4 Hara from Tower a couple of weeks ago as I want to race in a new class next year (19T) and as I already have a hara and loads of spares, thought it would be a cheaper option than going and buying an expensive later model chassis and still having to get spares as well.

Only raced the pro4 Hara for half a season last year and all but one time finished in A mains and didn't have any problems with the chassis. This was done with substandard race packs in 3300 where everyone else was using top notch 4200's, so I see no need to move onto something else if it is still competitive. I never really spent any time tuning the setup either so I think with a little more attention in this department i should be near the top!

...oh and I dig it to bits :)

The Pro 4 is an absolute rocket. I got some customized metal outdrives made and on the GTB/4.5, the car is a torpedo. I have countered torque steer simply by adjusting the droop and going up on the pinion. Long live the Pro 4.

[tecklancer]

when and why did they stop making the pro 4 i went on hpi's web site and i saw it on its disconiued section. this makes me sad :(

[bxpitbull44]

when and why did they stop making the pro 4 i went on hpi's web site and i saw it on its disconiued section. this makes me sad :(

back in July...right after I bought my Hara Pro 4! This is after they told me on the phone it wasnt and then the next thing I know *poof* discontinued. Everyone and their mother is going belt, so HPI is pouring their resources into the Hot Bodies Cyclone. You know what, bought one, hopped it up and...traded it for a Pro 4.

[overdosed]

hi guys,
i recently purchased a used pro 4 which has been hopped up to hara spec and OMG, its f'ing awesome. my first and fave shaft car ever :D but theres this little prick who keeps saying the pro 4 is crap, has terrible diffs, breaks easily, falls apart by itself, keeps crashing into walls, etc. i bet he's just jealous since hes got a fat RDX which is heaps heavy. so i want to hear from you guys and prove to that little jerk that the pro 4 doesnt suck. the diffs arent crap, mines perfect and suuuuuper smooth.

also i got a slight problem. when exiting out of corners i tend to have too much oversteer and i sometimes spin out. I have front shocks on 2nd from the top and rear shocks in bottom position. how do i stop my understeer?

thanks and i cant wait for your replies!

[microrcdude]

The diffs on the first batch of cars were crud, and HPI has since then fixed it. The car does not fall apart on its own (though it can if built waaaay poorly) and id much rather run a Pro 4 than an RDX.

What body are you running?

[graeme_rsa]

Hi Guys

Some time ago we muttered about the fact that HPI had discontinued the Pro 4! Seems that it is HPI - USA that has discontinued it!

HPI - Europe and HPI - Japan still list it - as the 1.1 version!

Whats more - the Japan HPI site now has a menu item called 'Hot Bodies' so I guess that the question about whether 'Hot Bodies' is / is not part of HPI is academic!

Another observation from the Japanese site is that they list the RS4 MT as current along with the new Wheely King! But they don't list the E-Savage at all! http://forums.radiocontrolzone.com/images/smilies/confused.gif

Cheers

Graeme

[microrcdude]

Hot Bodies is part of HPI. In fact, if you go on the Hot Bodies Europe site, it says "By HPI Racing" on the logo. The Cyclone, by hot bodies, uses almost all the same suspension components as the Pro 4.

[nomac]

anyone know where i can get some good carpet set-ups at? mostly for stock and 19 turn. not enough resources on HPI site. i must admit....the pro4 is kinda hard to tune to be fast. but once you find it's sweet spot, the car responds on a telemetry-like scale! simply incredible!!!!!

Hey slim, did you look at the entire site? Note the years they quote stuff and look at some of the other cars they carry. They are still using words like "debut" for Christ-sakes! Look at the motor mound...the old one before the Hara edition. They may not list the E-Savage, but it is carried in a banner ad along the top of the page. Looks to me that they havent updated some data at HPI Japan....not them carrying an extensive line HPI vehicles. They may have the cars available, but it is probably old stock. Super RS4, give me a break.

Quite probably the English translation version was out of date! I looked at the Japanese version - quite different! But how much out date could it have been? Months - years?

The Euoropean site seems to be up to date and they still list the Pro 4 and the Hara version! The blurb might be way out of date but the original point that I made was that the Pro 4 is not discontinued in Japan or Europe, only in the USA!

Lots of other kits have been discontinued by HPI - USA but are still available from Japan / Europe - the Savage ATV is listed as discontinued in the USA but still listed in HPI - Europe! In fact HPI-USA - New Stuff - shows off the ATV but it is classed as discontinued elsewhere on their site!

Perhaps HPI - "country" decides what their users want and stops importing what doesn't sell!

HPI - USA also does not have any links that I can see to 'Hot Bodies' yet the Japanese and European sites have Hot Bodies links on their main pages! Why?

Perhaps Japan still has a market for Super RS4 and RS4 MT's!

[bxpitbull44]

Graeme, you may very well have a point. Whenver I speak to the folks over at HPI, they seem to be a bit clueless and tongue-tied when it comes to giving out info on vehicles, whats to come yada yada. If I didnt live the Pro-4 so much, I would be hard-pressed to deal with a company that obviously doesnt know what direction they are travelling in.

[sLiTcH]

anybody knows why HPI discontinued this kit ? Anything wrong with it. I'm actually considering buying a used one to replace my TC3 Factory

[graeme_rsa]

The Pro 4 is OUT and the Cyclone is in!

I don't know what is going on at HPI USA as in my latest RC Car Action mag there were no Electric HPI adds or Hot Boddies Cyclone adds!

The European HPI sites feature the Hot Boddies Cyclone!

I do find it strange that the Pro1, Pro2 and the Pro3 were belt drives then HPI changed to shaft drive for the Pro4 then went back to belt drive with the Cyclone!

What is this telling us? Belt is better than shaft?

Hey Pro 4 Guys; Sorry about not getting back. My computer was Out for 2-Months.

My Pro 4 is a Nice Kit/Car. It runs well and it`s tough. It`s a Discontinued Kit; so to me it`s a Classic. I don`t run My Pro 4 anymore.....it`s now on a Shelf.....Ha Ha! I don`t want to damage it.

Team Associated now has a TC5. . . . .HPI might come out with a Pro 5.

There`s not much to talk on a Discontinued Kit; but if anyone has questions.....I`ll answer them.

Take Care

[graeme_rsa]

The Pro 5 is the Cyclone!

I wondered when AE would release the TC5 - according to their web-site = April!

I don't know about AE stuff, but it seems strange that HPI did belt drive from Pro '1', Pro '2', Pro '3' and suddenly switched to shaft with the Pro '4' and then back to belt with the Pro '5' (Cyclone)!

AE TC4 - shaft drive ... AE TC5 - belt drive!

Also observed that in my latest copy of RC Car Action mag there are no ads from HPI on the electric scene or from Hot Bodies re the Cyclone. Classifieds offer the Sprint! No Pro 4's or Cyclones!

What is going on at HPI / Hot Bodies?

Why the switch back to belt from both of the leading houses?

Cheers

Graeme

[GuyIsDamGood]

Hey Graeme;..... a few years ago Shaft Drive was the Fast - Way in R.C. Most R.C. companies was using it. Now it`s back to Belt Drive.
-The only Belt Drive kit I`ve had was a Tamiya TA04 TRF - SSG; it didn`t run too well because of it`s battery location. . . . .(I didn`t have it long; so I can`t tell you much on a Belt Drive kit.). . . . .I`ve went Shaft Drive since 2004.

I don`t know what`s up with HPI and Hot Bodies; it looks like they`re more into RTR - Off-Road. The Cyclone is a good kit; but they just don`t put any ads in in R.C. Car Action.....(I`m getting tired of Car Action; too much Nitro JUNK!.....I thought they had a magazine just for Nitro JUNK.....Ha Ha! -Or they should make a magazine just for Electric R.C. Cars and Trucks. . . . .I`ll Buy It.)
-Overall HPI and Hot Bodies are going through some problems right now.

They say Belt Drive is better. I`m staying with Shaft Drive.....until.....

I've stopped buying RC-CarAction as it seems to biased towards off-road 1/8 nitro! 1/10th electric on-road racing has just not featured for the past few months!

RC-CarAction has become just a review mag for the latest releases and no longer supports articles on 'getting the best out of you existing car'!

The last article I read with interest was the one on DIFFS - no mention of one-ways or on Spools - just the usual blurb on gear vs. ball!http://forums.radiocontrolzone.com/images/smilies/frown.gif

what spur should i try
thanks

[graeme_rsa]

Hi Minnesh

What spur / pinion were you using at the last race meeting? Basically you have to gear for the track! Rollout at CMCC for 540's is +- 42. What you have to do is work out which pinion / spur / tyre diameter will give you that approx rollout based on what you have! Shane has used a 42.39 rollout in the past using a 35 pinion and a 66 spur with 63mm tyres. I got a similar rollout using a 35 pinion and 69 spur with 65mm tyres. You have got to do the math! I've an Excel spreadsheet that you can use if you want!

Cheers

Graeme

[GuyIsDamGood]

minnesh; if you`re running on a Tight Track you`ll have to Gear Low.
-A 35-Pinion sounds cool.....graeme rsa is on it.

[minnesh]

well thanks guys
a beer for all at the track on me
ok here goes
spur 66
pinion 34 ..........48 pitch divide = 1.94
tyre diameter 64mm divide by pi which is 3.142 = 20.37 so......
20.37 divide byinternal ratio 2.4375 = 8.36 divide by 1.94 = 4.31
so my roll out is 4.31
is this correct
thanks guys

[GuyIsDamGood]

It should work-out.

[overdosed]

hey guys,
i just got my pro 4 2nd hand and have no idea about to the current setup. should i set the car up to the original default manual settings? is the original setting any good? does it have lots of traction or not much traction on the original setting.

i will be racing the car in stock class using RUBBER ONLY tires. only take off tires available for me. i will be racing on a very slippery track which gets lots of dust on it and i have a mazda 6 body shell plus a futaba S9451 servo in it with a novak gtx speedy.

any links to setups on that type of track? setup using a diff's in front and rear preferred.

Hey overdosed; it looks like we`re on the Same R.C. Car Level(Rubber Tires, Low Traction Track, Digital Servo, Front and Rear Ball Diffs and Powerful ESC).

-The set-up in the manual is a very good starting point. You can make you own changes from there.
-The Pro 4 is a good Kit/Car for Low Traction Tracks.

Sweep the Track before you run on it. . . . .You`ll see the Car/Kit run better(it will be Cleaner also).

Take Care

[overdosed]

rofl, at my LHS owns 2 tracks, onroad and offroad. on saturday nights we race offroad and all the dust blows east onto the onroad track. then onroad racing is on sunday morning! we wash the track with water and blow it down with the leaf blower and still no traction!

[overdosed]

also would you mind posting a copy of your setup please? i'd be interested to see what settings you have since we are on the same type of track conditions.

thanks

[mr lee]

Why don't you sugar the track for more traction...thats what we do here.

Big 200L drum filled with water and mixed with 5-10KG of brown sugar(depending on track size). A crop sprayer like attachment is connected to the bottom and the drum is on wheels so you can push it all over the track so the sugar water spreads evenly. Wait for it to dry and you have more traction! We do this for foam wheels but I am sure it will help with the rubbers!

You could also use some kind of traction compound on the rubbers!

[overdosed]

i only race stock, i wont use traction compound for that! only mod

thanks, and you get heaps of traction? any oversteer? perhaps a bit of understeer? i must try that setup after I record down my current setup.

thanks again!

[GuyIsDamGood]

I ALWAYS get some Traction because I SWEEP the Track(surface) before I run My R.C. Cars.
-I get very, very little Oversteer.
-I get some Understeer. . . . .even with New Tires and a good Track Sweep.

I run on a Track(It`s My School Yard R.C. Car Track.....I Set it Up) with 9-Foot Lanes. It gives alot of space to make good turns.


I didn`t put down other info in My Set-Up like:
-Shock Location
-Shock Fluid
-Shock Piston
-Type of Shocks
-# of Wheel Spacers

That stuff is up to you to set-up because your Track might be more curvy than mind.
-I run on a Flat Track/Surface.

Hi

We've progressed a bit from the sugaring days (takes ages to dry and attracts bees!) and now use stuff called Track Bite! This is what they use on drag strips! Dries immediately so no waiting - nasty stuff if you get it on your hands - difficult to clean off! It works well and the main benefit is that it is water resistant and is not washed away by rain! Can last for several race meetings!

Cheers

Hi

Droop? Front 6 and rear 5? I run 2 all round! Isn't your ride height a bit high? Are you restricted to rubbers? Yellow springs all round?

I suppose it's all about your driving style!

I'm still driving my TT-01 and have eventually got it 'perfect' with respect to how I drive! My stock 540 TT-01 lap times are comparable to my Pro 4 540 lap times - within 0.5s My Pro 4 still has a lot of development to do but comparing our 'fastest' 540 class (Pro 4) driver's lap times = 18.9s with my stock TT-01 lap times of 19.8s there is not much difference!

0.9s between a TT-01 and a fully sorted Pro 4 in 540 class!

I think it must be the driver :)

[filipinoguy]

Does anyone remember how much the Pro4 (original) was on towerhobbies?

Or if not towerhobbies about what was the average price they were going for?

[bxpitbull44]

Time to resurrect the dead. Seeing that I am pulling my Pro 4 out of retirement (and in good time, check the fastest R/C challenge). Wake up boys, reveille, reveille. Blow the dust off of those Pro 4's and lets talk shaft cars. Belts are fun, great out of corners, but shaft has my racing heart.

Filipino, when the Pro 4 first dropped, they were in the upper 360-380 range. Price dropped and the car was discontinued faster than a hot dog at a nathans hot dog eating contest when the Cyclone hit<----no pun intended. You can get a good roller in the $100-$150 dollar range. Meatballs trying to get $450 and better because they are throwing in stock brushed motors need to be castrated...dont fall for it. Get a good roller, stock up on parts like bevel gears and spur gears and you'll be straight.

[bxpitbull44]

whoa, no one has spoken since my post three days ago?!?!? What it do? Figure this, I am trying to step down a class or two, go to say 19T (8.5 Novak to be exact), am willing to trade a truggy with spare parts just to get a GTB and do you realize, no one is taking me up on it? In any event, hows the summer fairing for everybody?

[Kden46]

i am racing a Pro4 in our club racing. there are about 3 other guys racing Pro4's as well.

i am just not that serious about racing so i usually just check out what others are doing on here and ask a question here and there.

we run tamiya black cans, the track layout is on the small side. but it is a lot of fun.

this is my first try at racing TC and the Pro4 has made it a pretty easy adventure so far :D

Sitting low. What you gonna put in that puppy? She looks clean as he!!. Whoever had the car before you, looks like they took good care of it.

[filipinoguy]

I dont actually drive it that low, its just sitting that low for the pictures. :)

Anyways for now im just going to be running standard airtronics radio/servo, an old Novak Explorer II ESC and a Venom 19t motor and 1800 nicd battery. Nothing special.

Ill take some better pictures and post em up soon.

[bxpitbull44]

1800 nicad? Go to radioshack and get some gp3300's for 25 bucks. Feed that 19t.

[Kden46]

Just make sure that they are GP3300's! I have heard that RS is selling a different battery but still shows the GP's on their site.

I bought a 6cell SMC IB3600 pack from the lhs for $25 :D

I think I am getting a handle back on my Pro4. Finished 2nd in the A-Main despite some battery issues. But it is handling better now.

[bxpitbull44]

Forget the site...buy one in the store. They are GP's, just the ones that didnt make the high voltage cut at the factory. Numbers are good and the run times are decent. I still get eight minutes (til dead) when praticing. Now, if you want to get brawlic, go IB3800 for like $44 bucks. Those are nice cells! Now, dont get it twisted, I only run my Maxamps li-po, but, when I have run sub c's, IB's are the ish!

[Ginsu]

How does the pro 4 perform on carpet? Does it run ok with foams? thanks

[GuyIsDamGood]

Hey bxpitbull; What`s good?
-I`ve did some racing this Summer(5 EARLY Races at Block Parties.....we set-up the street - 3 times with Pro 4 and 2 with Evo 5). I`m really putting My Pro 4 on the Shelf now. . . . .I almost killed it just to get a 2nd Place spot.
-But My Pro 4 runs better than My Evo 5.


Hey Ginsu; you`ll have to get a different Lower Deck to run on carpet. . . . .Carpet racing will kill your car(crashes).


It`s a shame there`s no more Good Shaft Drive Kits being made any more(I don`t like the Kyosho TF-5; it`s the same as the Pro 4.). I`ll be done with this R.C. Car thing soon because I don`t like Belt Drive.

You know, I have to laugh a bit. When I was with HPI and the TC3 came out, all we heard was "shaft this" and "shaft that". We came out with the Pro 3 and were constantly asked, "Why isn't it shaft driven?"

Now I look at the new TC5 from Associated and laugh. Back then, we tried to say that belts were still good for electric RC but no one wanted to listen.

I think I'll pull my Pro 4 out of mothballs and take it out for a spin. Debating whether or not to go the brushless/li-po route though. Nice to see some of the "old" Pro 4s are still out there running. Seems odd not having a race class chassis from HPI when it comes to electric touring...and no HB doesn't count.

Man i am thinking the same exact thing right now! I started a topic in the electric forum with the concern over why HPI doesnt have a competition level TC. And i agree that HB doesnt count cuz it doesnt say HPI!

I still have my Pro 4 and its great. Its smooth as butter and handles like a dream. Not as good as the Evo V someone said? Well im kinda surprized because i would think by now the V would be superior, but not really due to how great the 4 still is.

AE and the TC3/3 were big on that "shaft is far better" thing, hell i went with it by buying a TC3. So its funny how they switched. I think they should have named it something different though.

Tom

[Troy Lyman]

The Associated TC Pro 2. LOL

Yea, wish HPI had a car with their name on it but, truth be told, I think HPI is sticking with their name and focusing on "HOBBY" kits. Savage, the new drift cars, the die cast stuff, etc. Sure you have the Firestorm and Hellfire but other than that most of their new stuff is hobby type kits, not race type kits. I was looking at my Pro 3 box last night and realized that every car on the box...RS4, RS4 Pro, Pro 2, Pro 3, and now the Pro 4 has been in my possession at one point or another. The RS4 has been converted to a RS4 Rally, the Pro went a long time ago, the Pro 2 is in my buddy's hands, the Pro 3 is sitting as a rolling chassis in the garage and the Pro 4 is collecting dust. Need to clean it up and get a capacitor for my Cyclone ESC...until I can go brushless/Li-Po.

[GuyIsDamGood]

I`m glad some people realize that the Pro 4 is ready ready for the Shelf. . . . .My Pro 4 only gets 2-runs a year.....Ha Ha! You can`t race it; Pro 4 parts are now hard to get.

what parts are those? The Cyclone uses alot of the same parts so if you broke a pro4 hub, arm, upright, etc...it will be pretty easy to replace due to that interchangebility. You just arent looking in the right places.

[Kden46]

Thank Heavens for PRS Pinions!!!! :D

They allowed me to run my Pro4 in our GT class that is now allowed to run 17.5 Brushless!!!

I picked up a 56t PRS Pinion for my Hacker 17.5. FDR is at 4.048 Was just about perfect for our track size.

The car ran great and is still pretty dang competitive!

I also use a Pro4 in our Trans Am class (6 cell Nimh and Tamiya Silver Can Motor)

I need to order some new main driveshafts though as the ones on the car have gotten grinded on by the ball stud on the steering bell crank :eek: Bought both cars used and just did'nt notice that was the reason for the ground down sections on the shaft. A little epa adjustment has fixed any further damage from happening but they need replacing.

[graeme_rsa]

I`m glad some people realize that the Pro 4 is ready ready for the Shelf.

Are you implying that 'shaft drive' is a thing of the past? If one looks at the history of HPI chassis, they had belt drive in "Pro 1", "Pro 2" and "Pro 3" then switched to shaft for the "Pro 4" then back to belt for the "Pro 5" = Cyclone.

With low turn equivalent brushless motors, belts seem to be the way to go - but what about the introduction of the 27T equivalent brushless motors - is belt still the best or does shaft still have a niche?

[GuyIsDamGood]

Hey Helgaiden; I forgot about the Cyclone. . .It`s a Pro 5 with Belts.


Hey graeme rsa; I feel Shaft Drive can hang with Belt Drive.....a few Shaft Drive kits won many races over Belt Drive kits a few years ago(using low turn motors).
The Pro 4 is a old kit and I`m just not using(racing) My Pro 4 anymore. Keep the Pro 4 alive.

Dont you meant to say "pro 4" with belts? Regardless, it still makes my point. My brother races his all the time. No parts issues.

brought a hpi pro 4 other day :D however it has a 72 tooth spur gear in it and i have a 21 pinion is it ok to race with it ?

You can use those gears. I believe they`re 48-Pitch Gears.....? I feel 64-Pitch gears are better.
I only use 64-Pitch Gears and I use the 98-T Spur and 29-T Pinion with a 10-Turn Motor(I max-out the motor).

That pinion/spur combo will put you at a 8.357 fdr which would be o.k. for a 10t mod motor.

But if your going to be racing stock 27t or 19t you will want to pick up some pinions.

[Troy Lyman]

Well bringing this up from the dead I finally got a Lipo/Brushless combo today to run the Pro 4 in the GT class. Got a 17.5 Havok system and some gears to put it where it needs to be. I may break down and pick up a Cyclone TC someday but it's just hard considering it's not HPI. Pro 4 will go to the fiance' if I do and replace the RS4 she's running in novice...that's right...she's rocking an original HPI RS4 with a Pro front and dual belt conversion...

[aalzuhair]

I for one will not let go of my Pro 4 .. I just love it :-)

Where are you guys getting spare parts from?

Thanks,

Az

[Troy Lyman]

I'm getting my parts from either Tower Hobbies, Ultimate Hobbies, Hobby People (if I'm desperate as they don't have much) or HobbyTown USA. Both HobbyTown and Ultimate are my first stops since they also carry Hot Bodies parts and I can use those for things like suspension arms and uprights. I got VERY lucky and found a set of silver sway bars and a gear set in the Hobby People Red bin (their discontinued stuff). Both times they were the only Pro 4 parts in the bin and both times they were exactly the parts I had come there for.

After all those are exhausted I hit up eBay...there are still plenty of Pro4 parts to be found there.

I got the Lipo/Brushless combo in the car and a new setup on it and I love the car! It handles great and I just need to make a few more minor tweaks and get my driving skills back up to par. Even so, last time out I placed 3rd in the RCGT class in a field of 10 so I think I'm doing okay for only two races back under my belt. I was thinking about shelving the Pro 4 for a Cyclone TC but I don't think that's going to happen for a LONG time now unless I need parts for the Pro 4 and just can't get them.

Next I need to get a 2.4Ghz radio combo as my trusty Airtronics FM is starting to go...

[GuyIsDamGood]

Yes; the Pro 4 is just as good as the Cyclone(s). I have a Tamiya TB Evo 5 and the Pro 4 can still deal with the new kits.
-I don`t race My Pro 4; it`s just too hard to get parts.

[bxpitbull4]

Guuyyyyyyyyyyyyyyyyyy! Whats good my man? Took a hiatus, now back. The Pro4 and R40 are the last of the mohicans for me as far as touring cars go....I am about to get into F1's! Now that is hobbying/rc'ing to the fullest. And as for the Pro4 parts thing, easy as 3.14...pi for you illiterates. The "Barracuda" shaft car fit the Pro 4. OR, when you see a Pro4 on sale, buy the CAR and strip it. Using my tactic, I bought two Pro 4's and stripped them for parts....the only thing I really ever break are CVD's and steering arms.

[GuyIsDamGood]

What`s good pitbull?
You know I don`t race my Pro 4 anymore(I still have a Brushed System in it).
I just run it in the school yard once a while.

I race My Evo 5 now; and I`m all raced out. I`ll be putting it on the shelf soon also. I Don`t have the money for this R.C. stuff anymore.

But I know you`ll keep up with it.
