Ok guys-

I'm looking for advice. I just purchased my first kit.(Well except for the Kyosho Ultima I had 15 years or so ago)

I have an MBX5 on the way. I do plan on racing. I'm VERY new to the sport and would love some advice and opinions.

I need to pick ...

Motor (Thinking anything from Rossi Top to WSII)

Servos (No clue here)

Radio (Dont want to spend 3xx for an M11- Wondering if the Spektrum DX2/3's are fine for me? I'd like to have the spektrum technology.)

Starter Box (again No Clue)

ANY/ALL advice welcome. Also anything else(major purchase) that I'm missing please feel free to let me know. Money is not an issue, however remember this is my first car. I want smart purchases. Just because I dont have a limit doesnt mean I want to hunt down the most expensive.

The track is medium to large in size.

Thanks for reading. Anyone willing to PM me and help me one on one, I could really use it.

Thank you for your time.

WS7-2
AIR 94358 Steer
AIR 94357 Th. Br
DX3 with Free Rx.

Starter Box Ofna one with single motor.

An also I want to say that I love my MBX5 ... eazy to work on, extra high quality (you'll see if you build one) It's such a great car.
i'll back the motor and steering servo recommendations.

for throttle brake, i'd go with another 94358. the extra torque is good for braking, and the 94358 is still plenty fast for quick throttle response.

for starter box, i'd definitely go with the Mugen BII starter box. it's smaller and a lot lighter than the big Ofna boxes. even though it's got 2 smaller motors, i've personally seen this box start motors that the ofna boxes simply could not. also, the MBX5 flywheel hole is a lot narrower than the Ofna buggies. the BII starter box has a much thinner wheel making it more forgiving to boxes out of adjustment. an Ofna box has to be dead on for the buggy to start. a guy i pitted for had an Ofna box and after struggling for a qualifier to get his MBX5 started, i went and got my BII box. it was a direct drop on and push and it was started. he bought a BII box later that week. the BII runs off 2 6-cell packs which helps keep the box light, but also makes charging the batteries quick and easy. they can be charged at the track if needed off a standard quick charger. they don't need to be charged overnight like the big 12v batts. i ran GP3300's in mine (which are cheap now that the 3800's and 3700's are out). on a full charge, i could do 3 rounds of qualifiers, a main, and several practice sessions in one day without even thinking about recharging the batts. i've gone 2 full race days on the 3300's without charging them. out of all the boxes i've used (my Ofna experience is not limited to one scenario, i've tried/used several) the BII box is the best for the MBX5.....hands down.

I also use a 94358 for steering (you can see it in those brake photos a few posts back), and have to say - I don't believe Airtronics speed claims for an instant. While it does a fine job, comparing it to other servos of similar (but lesser) specs, there's an obvious disparity. </rant> :P

I think everything stated so far would make for a good set up. I too run an Ofna single-motor starter box (the blue, chrome topped one) and haven't had any problems with it except for the already-mentioned wide wheel. Spektrum modules run beautifully in 1/8 buggies, you won't have any problems. For an engine, I'm running an OS VZ-B V-Spec and while it's not tuned yet (just finished breaking it in), it's really hauling already.. I can't wait to see what it can do once it's tuned properly (if I can ever figure that out, lol)!

Speaking of engines, has anyone seen reviews/dyno results of Mugens new Ninja line yet? They sure look good and sound great on paper..

for throttle brake, i'd go with another 94358. the extra torque is good for brakingHoly c***, that is overkill man. :) Seb above (hi Seb!) only runs a single brake disc with his 357, and I have to say that I'm seeing the light and will be dialing my HS-5925 (128oz/in) waaay out for next weekend as it was just locking the wheels too easily.

Hi guys, I just happen to come across a brand-new in the box MBX-5. It's not the Pro. I was wondering if anybody would take the time to tell me what parts I would have to buy to bring the buggy up to date. I think I would want to do it now that have to assemble while it's all part. I matters will put it together right the first time. Is there much of a difference from mbx-5 and the new ones. Thank you.

it's all personal preference. i ran a 357 and then tried a 358. i liked the 358 better. there wasn't a noticible difference in response time and the extra torque made my brakes work better. as far as the single disc brake, this doesn't make sense to me. unless you have the center diff locked, whichever side of the diff the single brake disc is on will cause those wheels to brake while the other's are not getting any stopping power. so say the disc is on the front of the diff. if you're going WOT and then for some reason need to slam on the brakes, your front wheels will get braking power via the disc (possibly locking up), however, at least for a split second or two untill the clutch disengages, the rear wheels will still be under power from the motor. this could cause a serious understeer problem. with the disc on the back, the rear wheels would slow while the front still had power, allowing the back end to break loose and causing an oversteer condition. i had a set screw back out on the front brake causing this situation once. the car was horribly difficult to control. try it if you like though. no body's stopping you.

as far as the single disc brake, this doesn't make sense to me. unless you have the center diff lockedOops, I didn't mention that - yes, he runs 100k in the centre diff.
I'm not encouraging that setup, but just thought that I'd mention that some people don't like much power in their brakes. I certainly can't see myself running a single brake disc, and definitely not locking the centre diff - but it does work for some people, I can't deny that.

I was wondering if anybody would take the time to tell me what parts I would have to buy to bring the buggy up to date.The differences between the regular MBX-5 and the Prospec are primarily for strength, weight and rigidity (and style :P), there's actually very few geometry changes - so other than for reliability and hard-core racability, you don't technically "have to" buy very much. I don't know how old your kit is, but if it's older than 5 or 6 months it may come with front lower arms and front uprights with the old geometry which had a little less steering. The rear hubs have different geometry on the Prospec also, and the rear camber links are shaped to avoid contact with the rims better. I seem to remember that the regular kit also came with a different fuel tank, but I cannot remember what the differences were (and think I remember hearing that some regular kits came with the Prospec tank anyway).

Yes, sometimes it does that, happens to me also if I try to access in a certain way. Try starting at this page:
http://www.rc-racing.com/SGM/index.php

On the left side, under "Discussions", click "Conferences", and then go from there..............

It is not as convenient as traditional forums, but I think it is designed that way on purpose. The inconvenience keeps a lot of casual (often careless and disrespectful) users away. You can't edit your posts, which is interesting. Most people actually use their real names, how often do you see that on a forum????

Still, it's far and away the best forum to stay updated on the latest and greatest RC racing news, and the pros will usually answer if you have a question......

Spring cleaning,getting ready for the outdoor season

Nutter

04-03-2006, 11:30 PM

E-MO: Spring cleaning was last week for me as last weekend was supposed to be our first race of the season. Unfortunately the weather decided to stomp all over those plans, as we were completely rained out. :(
On the bright side, I doubled checked my entire setup during the spring cleaning and found a few small errors that slipped by at the end of last year.

I think one of my first big purchases this year will be a new piston/sleeve (or entire engine if I feel lazy, lol).. my poor V-Spec doesn't seem to have very good compression anymore. I have to pull it apart to install a ceramic front bearing that I picked up anyway, so no big deal about installing a new p/s at the same time. Absolutely no blame on OS for this one, it's all me as it was my first .21 and I didn't have time to properly break it in. :P I'm going to run it for the first few races to see how it holds up, then decide what to do.

Hey guys, Im having trouble deciding what i should do. Right now I have an mbx-5 prospec, but I need a truggy to race in PA before summer. Im wondering if i should convert this buggy into a truggy, and then buy a completely new buggy? (so I would have a buggy and a Truggy) Or should I keep mine the way it is and get a complete MSR? Im thinking maybe I can find a good mbx-5 prospec roller with some kingheadz stuff on it and a conversion for cheaper than getting the complete truggy. Lmk what you guys think i should do!

PS, money is an issue. That is why i am having this problem deciding. If the price would be pretty much the same for this idea, then why not pay the little bit more and get the buggy and the conversion right?

As to the MBX5... I can go to any track and get it set up very quickly here are some recent lap times & no I'm not sponsored but I was was to get sponsored I wouldlike it to be Mugen. They realy do some serious reserch and they truly have been and areon top when it comes to bringing out a car that has so serious staying power.

I have read this thread from top to bottom and must say thank you to everyone for all the help without even asking a question, but I do have 3. First I have a MBX5 and upgraded it with most of the prospec parts. A rex P5-JR pro transmitter With Hitec Titanium servos (HS5955TG). :)
My question is

1) what is the difference in the fuel tanks
2) With the prospec steering anchermann I installed I added a trimmed standart anchermann below it in order to reduce bump steer-is this correct (trimmed the ears off).
3) Does anyone know the factory needle settings for a Rex P5
Thanks in advace you guys are great :D- MATT

Seb

05-14-2006, 02:52 PM

The fuel tank capacity is the same as it needs to meet regulation but the pressure fitting on the top is straight back rather than at a 45 degree angle.

I still have the "old" tank but I've done some small improvements all around.

One of my favorite ones is having a 4mm screw hold the rear chassis tension rod tight to the chassis. As you know, it comes stock with a 3mm screw. What I did is machine out the hole in the chassis to a 4mm and made the countersunk crater to a 4mm as well.

There is one kool thing I would like to get when Mugen releases it.. it's all CVDs made out of a titanium alloy that will be half the weight of the current CVDs.

-Seb

PS: This weekend at the local race I managed to squize a few more tenths out of the X5 vs. two weekends ago.... I got 4 holes in the shock tower and for most of the time I don't even use them all... I probably would if I traveled a lot more.

mattylo62

05-14-2006, 07:18 PM

Thanks for the info Seb. I asked at the 2 lhs in my area and guess what, the owners have raced x5s in the past, just stared at me when I asked them about the fuel tank, now I know not to go to them for advice. :eek:
Not an important question but it was driving me batty not knowing the difference. Seems that I have the new one.
Thanks :)
Still hoping someone can fill me in on the other two questions I had.

I ran in the Proline Max Challenge event over the weekend and both Hughes and Tillman were running the new shocks, towers and springs. (Longer Shocks with screw on bottom- aka no clip , taller/narrower towers, 3 new springs to go with the changes)

The track was very rough after quals on Sat. & the team cars appeared to benefit from the new parts.

It is my understanding the parts will be avaialable in about 1 month.

05-26-2006, 12:06 PM

Greetings all. I read an article on MBX-5 Prospec in May 06 issue of RC Car Action by Scott Hughes. He recommends doubling up the steering rack to eliminate bump steer. If you have the Prospec rack on already, use a stock rack underneath. Has anyone applied this theory. mattylo62 had a very specific question relating to this issue above on 3 May. Thanks in advance for any input that is provided.

mattylo62

05-26-2006, 10:42 PM

:rolleyes: Eagleye, I tried it. Took the standart Mbx5 steering rack and ground off the ears. I installed it under the prospec rack and it eliminated the bumpsteer all together. Come out of a corner now and the handling is unbelievable, you actually feel everything and every input is seen immediately, unbelievable control in all situations, but unforgiven if you make a mistake because that built in bump steer is not there to save your butt anymore. :eek:

Matty,

Check out this diagram. Is this how?

Thanks bro.

mattylo62

05-27-2006, 12:07 PM

Yes, I trimmed the ears off the standart, thinner mbx5 plate where you marked them, about 3/4 of the way to the screw hole so that there is no binding. I put the full prospec plate above and the stock mbx5 plate with the trimmed ears below. Since the plate now is thicker I did use a slightly longer screw in order to compress the 2 together securely. Good luck.

I just ran across the Innoative Designs 1/8 off road wheel balancer adapter (http://www.amainhobbies.com/product_info.php/cPath/89_139/products_id/4354) on A Main and was wondering if anyone balances their 1/8 scale wheels? I actually didn't really see the need on my 1/8 or 1/10 scale but if it knocks a couple tenths off lap times, maybe I should. I balance my monster truck wheels and that makes a huge difference. Just curious what everyone else is doing.

Nutter

06-06-2006, 01:29 PM

Eagleye: None of my current wheels are balanced, however I do have that wheel balancer adapter - I plan on using it, but keep forgetting to buy wheel weights. :P Other than performance improvements, don't forget that it'll be a lot easier on your wheel bearings too.

Evader, congrats on getting an awesome buggy! There isn't a whole lot of difference. Alot of the Mugen Team drivers run the regular version as they prefer the extra bit of flex it has over the Pro-Spec.

But, here is a run down of the pro-spec parts to the best of my knowledge.

MUGE0503 - 5mm Front Shock Tower
MUGE0504 - 5mm Rear Shock Tower
MUGE0119 - 5mm Front Lower Arm Mount
MUGE0118 - 5mm Rear Lower Arm Mount
MUGE0311 - 5mm Ackerman Plate
MUGE0120 - Aluminum Front Chassis Brace
MUGE0121 - Aluminum Rear Chassis Brace
MUGE0126 - Aluminum Rear Hub Carriers
MUGE0703 - One Piece Engine Mount
MUGE0123 - Lower Suspension Shafts w/ Nuts
MUGE0124 - Rear Lower Shafts w/ Nuts
MUGE0807 - Titanium Steering Rod Set
MUGE0808 - Titanium Servo Rod 35MM
MUGE0117 - Titanium Rear Upper Arm

Now, I would suggest you run it stock for a bit and see how it feels for you and if you break anything. The stock MBX5 is a very tough buggy and will take a good beating. So far I have only managed to break one rear suspension arm, and I lost an e-clip once on the lower front arm and replaced them with the threaded shafts with nuts from the pro-spec kit. But other than normal wear and tear on things like clutch shoes, bearings, etc. I have not had any troubles out of my MBX5 and am very pleased with it. The only major thing I have changed is the chassis braces. I switched to the pro-spec braces as I felt it had a tad too much flex for me.

Most racers if they are running the pro-spec kit, will change out the aluminum hub carriers on the rear for the stock plastic units, as the aluminum ones tend to break the rear arms faster. I have not had an issue with the stock ones so I left them alone.

Like I said, just run it stock for a bit and see how it holds up for you. If you find you are breaking some of those parts I listed, then change them out.

Also if you have the time, go through all the 80 + pages on the thread here. There is alot of good info in here.

And if you have any other questions, just ask.

Hope this helps. :)

The best upgrade is probly the shock towers, i found that when i used a spare standard one i ended up bending it the same day.

C0801A looks like any ball hook screws but it had a rectangle hole cut right in the middle... i wear off mine on the side and i'm afraid that the screw will just snap in twos... can i use something similar as a replacement with the same dimension but without the hole cut out in the middle?

how often do you guys bend the the center drive shaft? my is slightly bend... very slightly only noticable when you push the buggy and the shaft is spinning. do i wait till i bend it further more before i change or do i change it as long as it's not 100% straight?

balang_479

10-02-2006, 03:27 PM

I wouldnt change the Shaft, just bend it back into place its still perfectly fine, clamp it in a Vice an with a small hammer notch it back straight, and check how straight it is by spinning it with you finger, (or drill).

Oops, well it looks like I found the answer to my own question in this thread. Read all 83 pages making sure that I would be happy with the trade if it goes through. I hope I get it as the buggy sounds awesome!

Great decision. there is an even more active & recent discussion on MBX5 in www.rctech.net in the buggy forum search for MBX5.

I usually get my parts locally and order online if i couldn't find them avail here. The 2 places i order from are www.rcplanet.com & www.speedtechnitro.com

hope that helps

Well that will depend alot on the track you race at, as well as if it will be your first .21 sized engine or not.

But, RB , Novarossi and OS all make great motors that should fit anything you may need.

If it is your first .21 you may want to stick with the lower end motors. Like the OS RG, or the RB Econo 3 port, or the Novarossi N21B. All are great learning motors that still produce a good amount of power.

Now if you are used to tuning an engine and want something that will be competative, Try the Novarossi P5 line, or the RB S5 or S7, or the OS V-spec 21. Those are good all around power makers and seem to do well just about anywhere.

May be a good idea as well to check out your local track and see what guys are running there.

ive got some guy trying to tell me that he bought a conversion that he put on his 4 that converted it to a 5t, is that possible? I would assume that he's talking about the JT conversion.

What do those o-rings in the diff heli gears do?
Should i use them...i've seen that most pros don't...!!
I also want to ask whether a 10/10/3 diff setup would be OK??

I've got a shock spring question. Are there stiffer springs than the grey springs or are those max? Thanks

Gentlemen, picking up the X5 Prospec after two years on no racing. I've noticed that Mugen has released a slightly revised version of the Prospec. Can anyone give me a quick rundown of the differences? Anything worth incoporating?

Also, I noticed that the part numbers for the front and rear lowere suspension arms have a "B" added to the part number for the new car. What's the differences in the arms?

Thanks.
