Duratrax Delphi Indy Car

[AirbrushFanatik]

Ok i am getting a Streak esc, i dont want to be using a lathe 24 hours a day, but i wanta superfst moter, any suggestions(looking at the Tower Hobbies speed secret)

[Wizardman_1]

Just a quick question but can you get this car to drift like other r/c's, and since the stock tires are really hard they would work perfect.

[AirbrushFanatik]

The Delphi is a very good drifter, although it looks odd drifting a indy car! it has plenty of torque and the tires are extremely hard a perfect combo. just be careful with throttle and countersteering, to much will spin you out quickly

[guver]

I can't keep from spinning out.
I'm getting a 14 turn for my indy too.
I just got a 4-tec, and by comparison the indy is about twice as fast .

[Wizardman_1]

sweet, would running front foams help the spinning out so you still have the drift but you have a little more steering.

[Janders]

Yes, but I would recommend both front and rear foams, just run softer tires up front

[Wizardman_1]

wouldnt it wear a lot of the tires out fast though? Dont want to waste all that money just to wear out tires every run.

[tl-01 4 Life]

What would be a better motor for my delphi w/ stock gearing, or maybe a 20/21T pinion?

TH Speed Secret 14x4
http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXJA78&P=C
OR
Kyosho Krypton Krystal 14x2
http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXW932&P=0

Also, what other 13/14T motors would work as good or better for the same price?

And how would these motors do with a 20 or 21T pinion. The stock pinion weighs about a pound so I want to replace it, and I also want higher top speeds.

So which combo should I go for:
1) TH Speed Secret 14x4 w/stock pinion
2) TH Speed Secret 14x4 w/20T pinion
3) TH Speed Secret 14x4 w/21T pinion
4) Kyosho Krypton Krystal 14x2 w/stock pinion
5) Kyosho Krypton Krystal 14x2 w/20T pinion
6) Kyosho Krypton Krystal 14x2 w/21T pinion

Sorry for the long post, I was just craving more top speed. 50mph perhaps ;)

THANKS, tl-01/delphi 4 Life

[tl-01 4 Life]

Make that stock, 21/22T pinions. Not stock 20/21T pinions.

[Janders]

Go with a smaller pinion to avoid overheating your motors. The stock pinion (with the speed secret) actually had a lower top end then when I swapped it out for a 14 or 15T pinion. Hotter motors need to be geared shorter to make up for their lower torque.

With the right batts and geared correctly the Speed Secret should make 50mph
check out:

http://radiocontrolzone.com/cars/calculator.asp

I'd also go with the Speed Secret(I had it until I blew it up with 14v) because of the quad wind for a high 40k RPM...I don't know or have experience in dealing with the Kyosho.

[Janders]

BTW-
for the calculator the stock tires are 2.44 in tall(diameter)
and the final ratio is the spur(72) divided by the pinion(14,15,21,etc)

[EvaderRacer76]

what do u guys think the rpm of an orion 10x3 BB is?

[guver]

My guess is about 45,000 +

[guver]

Hey I just put in a 14 turn motor with stock gearing, It's about as fast as the stock motor with 30 tooth pinion. It really cooks. I didn't bother to solder the caps on, and everything was going great until I hit a little blip in the pavement and it went airborn at full speed, landed on it's back and went scraaaaaping down the asphalt. After that It kept glitching so I thought I would put the caps on and charge the tx batts.

Later I found the anttena wire and tube where sanded off and gone.. hahah fun fun You shoulda seen that thing flying like kite. It just took off. Anyways I'm real happy with the towerhobby motor.

[tl-01 4 Life]

Do you guys recommend using the tamiya foams or rubber slicks?

I will be getting the harder foam/rubber for tire life. What will let the spinning stop?

Any help would be Great!

Also, what would be better w/ a stock motor? A 22,23,24T pinion for top speed and still having good acceleration.

THANKS.

[guver]

I recommend the foams, the slicks were too short for me.

[Janders]

the foams(Jaco or Associated with stock rims) are a lot cheaper, not to mention better traction than the rubbers

[tl-01 4 Life]

What about a pinion choice for the stock motor?

A 22,23,24T pinion, I want top speed while still having good acceleration.

THANKS, Kyle

[Janders]

by gearing up you can gain top end, but your motor will run hotter and have a shorter life.

[tl-01 4 Life]

Which of these tires should I get: I want long life and a better traction, also how much ground clearance will I lose with the 1/12 foams?

Tamiya F1 Rear HBR Medium Sponge (2)
http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXGH04&P=7
Jaco 1/12 Medium Standard Rough Cut Donuts Green (2)
http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXCMG0&P=7
Jaco 1/12 Medium Standard Rough Cut Donuts Aqua (2)
http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXCMG1&P=7

Also, will these fit?
Jaco 1/10 Medium Firm Std Rough Cut Foam Donuts (2)
http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXCMF8&P=7

THANKS, Kyle

[guver]

the 1/10 look too big on the ID, With the jaco's you'll lose a couple of mm clearance.
I recommend the tamiya's when they're mounted you won't lose much clearance if any at all, they great traction and life too.

I put mine on stock wheels with the two center ribs cut off.

[guver]

What about a pinion choice for the stock motor?

A 22,23,24T pinion, I want top speed while still having good acceleration.

THANKS, Kyle

I used up to a 35 toooth gear, but think a 28 is the best for me running in very large parking lot full speed almost all the time.I would get a robinson 6 pack, and start with a 24. I have since gone to a 14 turn motr and a stock 20 tooth gear , it's about the same top speed.

[tl-01 4 Life]

THANKS guver for all the help, I know you live in Ohio so do you know of any nice tracks around the Columbus that are indoor/outdoor?

Also we should get some other Ohio drivers and race/bash sometime.

I think I will go for the 6 pack.

THANKS, Kyle

[guver]

sorry, don't know any tracks in columbus

[EvaderRacer76]

hey, does this seem wierd to u guys, according to the calculator, if i use a p2k stock motor--i used 28,000 rpm, (even though the motor says 30,000), and a 23-tooth pinion, and had the tire diameter at 2.32in. (the foam mounted ones) the car will hit roughly 60mph..!?

[Janders]

No, the calculator is right, but whether your motor can actually spin that fast under load is innacurate. You can gear to 200mph, but the motor won't be able to get you there. Unless you run a hotter motor, you won't get over the stock Delphi's 32mph.

By running a stock motor with that gearing would just overheat the motor and result in poor acceleration(compared to shorter gearing)

[EvaderRacer76]

ok, that all makes sense now. so what pinion do you think i should use with my 10x3 (est. 45,000rpm) to make it go as fast as possible? I made this little chart using the 45000 rpm and 2.32" dia. and corresponding gear ratios using different pinions sizes with the 72 tooth spur:

pinion size:
15 - 64.7 mph
17 - 73.3 mph
19 - 82 mph
20 - 86.2 mph
21 - 90.6 mph
23 - 99.2 mph
25 - 107.8 mph

I know that any pinion over 20 teeth probably won't work, so which one do u think i should use to go as fast as possible, but not overgear the motor?

[Janders]

I'm guessing with that motor, the limit on your speed (how high you can gear) will probably be dependent upon the batteries you use. I'd try a bunch of pinions ranging from 12-16..buy a robinson 'package' deal and just start with the smallest and keep gearing up until the motor gets too hot, or you start loosing speed, and then drop it back down a pinion. I ran my speed secret 14X4 with the stock gearing and it was close to the stock speed..when I geared it down to a 15 tooth it was actually faster than the 20 tooth...right now I have a 24tooth, running 14 volts with a 550 can....I just have to work out my glitching issues before I can get a good high speed run :)

[EvaderRacer76]

yeah, i bought a robinson package of odds 15-25 thats why i listed those ones, i will try all of them like u said. thanks for the tips

on another topic, do you think that the delphi could quite possibly be a competitor for the "world's fastest rc car challenge"? i know that there are other direct drive cars that are probably faster but wouldn't it be cool if a little $65 duratrax could beat associated's cars and other really expensive cars. just an idea.

[Janders]

The main concerns with top speed cars are going to be the motors(brushless probably, or very high end $$$ brushed) custom aero(people with access to windtunnels and test tracks will have an advantage) and batteries that can handle high current. Essentially, there will be enough custom work, and high end parts, that the car you start with really doesn't matter since you'll be changing/modding quite a few parts.

Like most speed competitions it will be a contest of money and experience, and inside connections(custom made motors, pro level batteries,etc.)

[EvaderRacer76]

is this thread like dead now or what?

[EvaderRacer76]

hey Janders, what speed control are you using for dual batts. in your delphi?

[Janders]

I swap the same speed control between all of my vehicles(clod, dagger,rally,mr4-tc) and it's the all-great Supre Rooster

[EvaderRacer76]

isn't the super rooster only rated for 10 cells?

[guver]

yes, but most you can over do it somewhat.

[save1992]

i'm going to buy this car what is the first thing i should get

[guver]

I would say rear foam tires , probly have to buy wheels too unless you can remove the stock tires off them withiout hurting the wheels.

[Janders]

Get foams all the way around...boil the rims/tires to remove tires.

[EvaderRacer76]

which one of these bodies will most likely fit the best?: (take out the space between the w ww2.to.....


Lola:
http://w ww2.towerhobbies.com/cgi-bin/wti0001p?&W=000447078&I=LXCSN8&P=K

thanks

[Janders]

I think the Lola would be the best fit, as the GT-1 is a little wide, an dthe other one is designed for a TC

[tl-01 4 Life]

Well guys, I put a 12x2 Speed Gems Pro in my car and I was wondering if I should go down in pinion size. I was thinking that I should put in a 16/18T pinion instead of the stock 20. I'm buying the Robinson 6 pack even that gives you 16-26 even #'s.

Any info would be great, THANKS

[Janders]

Definitely go down in pinion size, otherwise you'll cook the motor. Start with the smallest pinion you have, and work your way up, testing for both acceleration and motor heat, until you're at a happy medium between both.

[jtatz]

Does anyone still have interest in the Duratrax Indy car?

I see the last post is dated in Jan of 2003... I bought a RTR recently, and was curious if there were people still racing them.

[Janders]

It's hard to find a class to race these cars in.....Although if you have smooth streets they haul a** and are great for learning how to control a high power RWD car

[timmygreek]

We are trying to start a spec class for these at our track in PA. They are great sellers at the shop, they just need tlc. And a tire change!

[guver]

Mine is in need of an esc right now. I've been using the 4-tec instead.

[jtatz]

Does anyone have tips on replacing the main shock?

I bought new tires, motor heatsink, and antenna tube.... and the oil filled main shock - but I can't figure out how to correctly install the oil filled shock.

There is new installation hardware for it, but no instructions whatsoever. It doesn't seem clear to me by just looking at it. What have others done?

Any tips are appreciated :)

[jtatz]

Does anyone have tips on replacing the main shock?


I emailed Duratrax and they responded.. Cool!

This would be for anyone else who isn't smart enough (like myself) to figure out how to install it :)

"You would take the other shock off the vehicle including the ball
stands. Than take your new shock and with the end with the ball, insert
the small screw in to it and screw it on to the back mount of the
chassis. Than install the other screw from the bottom up in the front
hole and screw the black nylon piece on to it. Than put the other end
of the shock on to it and secure with the nut. That should do it for
you."

[EvaderRacer76]

yes, it is difficult to find a class for the delphi, i'm trying to start one at my LHS but i don't have enough people yet.

I have 2 delphi's - one with a p2k2 pro and the other with a orion orbital 2r 10x3

[SS Pede]

Hi everyone, I've been considering the Delphi for a while now as my first on road car. I like it because it's simple and fast (and cheap), and I don't think I would mind the challenge of 2wd if I get it. I'm wondering...does anyone drive (or has anyone driven) the Delphi with the Novak SS5800 system? I figure that would be insanely fast, I have one in my Stampede and I love it. So I bet if I ever get a road car I would eventually prefer brushless, with its performance and low maintenance. Sounds like even with foam tires the SS5800 would be ridiculously powerful, but I could set it on "sportsman" mode to limit RPM/acceleration. I could get the slower 4300 system but the 5800 is faster for the same money, and can be made slower with the sportsman setting. Does this sound wise? What I really want is little maintenance and great run time, but speed is a plus! How does the 5800 seem as a power source?

[EvaderRacer76]

a 5800 might be almost too fast and powerful for it, but it was have an amazing top end. My delphi is pretty hard to drive with a 10x3, almost to the point where i can only drive it on really smooth, open surfaces with a lot of grip because it loses grip with the 10x3 really easily, even with the foam tires. although, some traction compound might help that problem.

[AirbrushFanatik]

Evader, have you clocked the speed on that Delphi?
10x3 in there must be amazing!

[EvaderRacer76]

no, I have not yet clocked it yet (can't get ahold of a radar gun.) although, there is one of those speed trap things for full-size cars that the police set up down my road a little ways, so i will eventually try to clock it with that. :D

[AirbrushFanatik]

EvaderRacer76, that would be really cool, any ideas of entering the fastest RC car competition?:)

[EvaderRacer76]

they took away the speed trap earlier this week, before i could try it. No, I don't think my car is quite fast enough to enter it, and i live in wisconsin and i don't feel like going to california to enter

[guver]

I'm gettin' sick of wasting a spur gear every run, I think it's the dirty surface I run on and was there a way to convert to a spur that'll last a long time?

[asif2290]

Well, I ordered this a few days ago, should come today or tommarrow, but I cant wait.

This is my first actual hobby class car, and im too excited.

:)

[Vision]

Just installed some foam tires :)

http://www.visionaryracing.com/test2.jpg

http://www.visionaryracing.com/test3.jpg

[guver]

I'm ready to dump my indy I don't even use it anymore on account of the spur gears stripping. whahwhahahw

[EvaderRacer76]

I think the ball diff. kit allows use of standard spurs for the delphi, try getting one of those before u ditch the delphi.

Is your gear mesh too loose? i haven't had any problems with either of my delphis spur gears.

[guver]

I set it so it is the same as my offroad vehicles, they do ok. the gear is always kinda wobbly and it may be the dirty surfaces I run on there's lots of dirt, stones and rough stuff.

[Vision]

Guys, whats the easiest way to get a bit more top end speed with the stock motor ? what gear / pinion do i need ?? (post link to towerhobbies if possible with the part #).

Handling btw with the foams is amazing!

my gears so far are holding up great, done about 14 full charge runs

[guver]

gotta love those foams. ... I used a 30 tooth pinion with stock motor if the area is big enough.

[asif2290]

Vision-
Maybe removing some weight?

How do the foams handle, is it still able to spin out as much?
Thanks

[Vision]

Guver - so with a 30 tooth pinion on the motor how much more top end speed do you think I'll get ? and how much will it affect the life of the electronics/motor ?

Asif - the surface I ran on it (shown in the 1st pic above) was newly paved and clean so no spin out problems with that plus the foams.

[guver]

Theoretically if stock went 23 mph then the 30 tooth would do 30, but realistically 28-29 cuz of wind and power requirement to go faster.

It won't really affect the esc, but will make the motor not last as long, it will get quite hotter.

I just used the 30 cuz it was the biggest I had at the time, I did use a 35 on wide open parking lot, but that is I would consider absolute max. just for high speed record.

[Vision]

Cool, I picked up a 26T robinson pinion gear today. Gives the car a nice little boost in speed and makes it a bit more driveable imho.

One thing I noticed with the aftermarket pinion gear vs the stock one is that it's not as wide, perhaps that's why the spur gear strips ?.

[guver]

Hey ya, good observation. Also some motor shafts are too short for it.

[EvaderRacer76]

hey Janders, did u ever get a speed run with your dual batts. yet?

[Matthew007]

Hey I'm really interested in buying one of these for 50 bux on TH. Funny thing is the ESC itself is worth 50$ at TH and the motor is 20 I believe. Currently I have a Traxxas Bandit with a Duratrax Streak (the black esc with Forward/Brake/ABS 12+Turns up to 10 Cells, 40$ great esc), a 14X2 old Associated high torque motor made for 4WD from sheldon hobbies, and two 3K mah 7-cell batts. I'm getting a car soon and I could drive it to Floyde Benett Field here in Brooklyn, NY; it's a abandoned small naval airfield it's a ghost town on weekdays and on weekends I think they use the two airstrips for rc cars and planes. Also, I heard in another forum that putting weight in the front of the car produces more traction so im going to use the inline battery conversion to add more wait to weight to the front of the car. I'm guessing I should hit around 40 mph if stock is 32 mph. The ABS and traction control on the streak esc will greatly help I think hehe.

[microrcdude]

sounds great! Wheres this naval feild at? If its close to me, i might come up when my finger is no longer broke.

[Matthew007]

Here's the map http://maps.yahoo.com/maps_result?ed=5KDX_ep_0TqiZIwC_6GrJqB2mZQALXtD9_j eyA--&csz=brooklyn%2C+ny&country=us&new=1&name=&qty=

Basically, get on Flatbush Avenue and drive south till the end.

[Tc3-dude]

Im intrested in getting the Delphi Indi. (considering its only $50 on towerhobbies)
What would I need to get if I buy the $50 Prebuilt kit besides a radio. Also im going to put a 14turn motor in there. Do I only need that motor brace?

Thanks
Paul

[Matthew007]

The included esc can support only 20+ turn motors so you'll need something like a Duratrax Streak esc which is 12T+ but has no reverse http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXD523&P=C (but its cheap and cool :D ). A servo for streaing you'll need, and a 6 or 7 cell battery (it says 6 cell battery though it surely looks like it can fit a 7-8 cell hump but 8 cell will burn out brushed motors). As far as the motor brace you mean this: http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXDBT7&P=Z ? I'm not sure you need a 26$ aluminum peice of metal but if the stock one aint adjustable to fit different size pinion or spur which requires moving the motor then I guess you have too, but on plus side it'll keep motor cooler.

[Matthew007]

Someone perform CPR!

[microrcdude]

huh? ur confusing me? did you crash again? LOL

[SS Pede]

"Also, I heard in another forum that putting weight in the front of the car produces more traction so im going to use the inline battery conversion to add more wait to weight to the front of the car."

The RCCA review of the Delphi mentioned that with the inline battery setup, the car swapped ends "almost without warning." Seems to me that by putting more weight up front you also lose weight in the back, which could let the rear end swing around more easily. Not having tested the car myself, I can't be sure though.

[delphidude]

i put a b3 buggy wing on the back of my old delphi and slide the battery as far forward as possible. if i had foams, i would bet that car wouldn't handle that bad.

[microrcdude]

well, i have a B3, so all i need's a Delphi!

[delphidude]

but if the wing is just a tad off center it makes for and ugly sight as at high speed turning didn't do anything cause the front wheels had no grip. best thing was to brake evenly

[microrcdude]

thaught of somehow mounting a B3 wing on the front?

[delphidude]

eh idk i though the stock front wing worked well for me

[delphidude]

the long road behing my house where people street race just got repaved . it should be perfect for the delphi. also working on trading fopr a novak 5800 brushless et up for the delphi

[microrcdude]

are their a lot of cars that drive on that road? Too much people will heavilly increse the chance of you wrecking your delphi. Sounds fun though!

[delphidude]

yeah its a busy road at times but at like 3pm its empty. alot of busses use that road. i had my rc10gt ran over by a bus and then a close following suburban

[microrcdude]

if you see cars coming...........GET OUTA THE ROAD!!!!!!

dont be like delphidude, with the worlds flattest GT

[delphidude]

actually it didn't come out that flat and i lost radio reception

[microrcdude]

i c. I lost reception and hit a curb at 40. $75 later, its broke again.

[Matthew007]

As Nelson says: HAHA

[thehappyone]

HI what do you guys think $50 prebuilt, is it a good deal for the Delphi?For the people that own this car does it drive strait or do i have to buy anything to get it to drive strait. My TT-01 does not drive strait after i make some turns.

[microrcdude]

thats good. I would spend the extra $30 and get a radio for it. http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXAEJ5**&P=7

[thehappyone]

The rtr does it come prebuilt?

[microrcdude]

all you do is take it out of the box, put a battery in it, and drive!

[save1992]

i just got one of these is there any other bodies you can get for it, can you get chrome rims

[microrcdude]

you can get clear bodies. and, you can get some high-downforce LMP style bodies.

Chrome rims? Janders, help please!

[rcster3000]

I own one myself and its packs a good punch on speed and everything else it has a very good price but the down side is it spins out a lot but all in all it is a very good rc. so to people who are in the market for a cheap,fast,economical,and the most bang for your buck rc this is the one!!!!!!!!!!!!!!!!!!!!!!!!!!!

[rcster3000]

HI what do you guys think $50 prebuilt, is it a good deal for the Delphi?For the people that own this car does it drive strait or do i have to buy anything to get it to drive strait. My TT-01 does not drive strait after i make some turns. You need to get it a radio because it is a very good car happy
:cool:

[guver]

My only complaint is it eats spur gears.

[asif2290]

My only complaint is it eats spur gears.


Well, now, I havent run my Delphi for 2 months, due to a diff being shredded.

And also, my ESC stopped working, and when I sent it in, they said that it worked perfectly, and sent it back, but it still doesnt work.
:mad:

And to top it off, I have to send it in ASAP, since my warrenty is expiring in a few days. :(

[rcster3000]

My only complaint is it eats spur gears.
yeah if you run it too much it will,stupid,i have one and it is not easy dropping on gears i think it does that because of the motor. you should get it a tamiya sport tuned motor it worked really well after i put mine in. it still spins out but it is a much better car. dude get a motor,stupid moron.

a fuggedabtit
:cool:

[jdm3849]

Now that I got a job and haven't been running my RC's, I have alot of money.

I always wanted the Duratrax Delphi, so I went on-line to order one. When I opened up the Tower Hobbies page I saw the price and was shocked. It's up to $190. Thats insane.

When did I raise in price? How long ago? Think it'll go back down?

Thanks

[guver]

they were $79.00 I am considering getting rid of mine, I just don't use it. All it needs is a spur gear.

[NotWalkinBlind]

Someone at TH musta goofed in updating their site... and then corrected their error... it's showing as $79.99 now.
http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXAEJ5**&P=ML

[microrcdude]

I know, it went from like $80 to $190, now its good to see it back down.

[guver]

Where can I get one of these?

[NotWalkinBlind]

Where can I get one of these?Ever try Google.com?

[guver]

Thanks, that bottom one appears to have the delphi

I am wondering if anyone runs theirs anymore? I only run mine about 1 / month. I am still eating up spur gears and may just sell it.

Getting the ball diff seems out of the question on a 79 dollar car and the spur gear will continue to go bad I think. Must be the dirt surface I run on.

[EvaderRacer76]

yeah, i haven't run mine ever since i got my tc4. I've been working so much on the tc4 that i haven't had time to work on my 2 delphis. One just needs a kingpin, and the other only needs a SERVO SCREW! thats how lazy i am! I think i will get the kingpin and servo screw this this wednsday and start running them again. should be fun. I run one with an Orion 10x3 BB, and the other with a p2k2 pro.

[Jeff Shriver]

For those of you who ran the Tamiya Spare Gear Set (50506) and the Tamiya Differential Ball Plate Set (50388), did you have to replace the spur gear to match what was in the car? I thought I read the Tamiya spur in this set is 63T, where the spur which comes with the Delphi is 72T.

[microrcdude]

you mean the pinion? Im sure you'd have to

[Jeff Shriver]

you mean the pinion?

No, the spur that is in the Tamiya Gear Set #50506. Is the Tamiya spur really a 63T?

[crazy_matt]

where can i buy one of these for cheap?

[guver]

My used one is $99

I just went to 2S LIpo and my indy weighs 1000 grams now.

Sweet! I got two lipos I'm using in my TC4 right now maybe I'll throw one in the delphi for a day. I turned one of my delphis into a dragster with some old bolink parts. My other one will be setup with a Novak 13.5 motor and a lipo for 40+ (hopefully) minute runtimes.
