Dynotech still makes yellow rear wheels for B2/B3s. I ordered some the other day and they showed up almost overnight!

Yes It fits a bit tight because the height of the battery. I tapered the end of my battery hold down strap to make it fit better.

Thanks lil sis! I ordered 2 sets.

Tried these in my B4 and found I couldn't get them to fit in my FT B4 without surgery to either the battery case dimples or the rear shock tower.

Not sure of the longetivity of doing this (or safety in the case of dremeling the battery case) so I sent them back and got a couple of iP3800 35C LiPos that fit perfectly (from Feral Batteries).

A few people here in Australia use a Kimbrough 69T Spur:



...with a Losi/AE front wheel bearing in the middle.

In the outer holes they use 12 x Traxxas Slipper pegs (you may need to make the holes slightly bigger):



...instead of the hex pads that come with the kit.

I have this set up in my brand-new FT B4 (albeit mine is yet unraced nor even been on the ground yet ) with a 40T pinion and a Trinity Pulse 17.5T. Just in case I have spare pinions from 37T to 42T in the event I have missed the sweet spot .

Probably for the umpthousandth time, but for those who've run rc cars longer than I have and race 2wd mod, is the current brushless takeover due only to maintenance? Every now and then I see a 2wd mod car running and it really seems to be a lot more driveable. Brushless is obviously powerful but does it give the same 'feel' as a high spec, well set-up brushed mod motor in 2wd? Call me a luddite but I'm considering on tracking down some brushed gear to try and see for myself.

I just got a brand new B4 and i was wondering if there were any building tips i should know. Im going to be running mod with lipo. i have seen some people balance them front to back and left to right should i do that that and if so where?
Also what is a good set up for hard packed dirt that turns into blue groove?
Thanks Jason Hunt

Maintenance is a big factor along with much more consistent performance. 2 HUGE reasons as far as I'm concerned. From what I can tell (I'm still using up my brushed stuff, no brushless for me.......yet $$$) the ESC's are so programmable that they can be setup to mimic a brushed motor or perform slightly better. Drag brake, initial drive, throttle curve, frequency etc. are all programmable on the high end ESC's either through a laptop, the ESC itself or a proprietary hand-held sort of thing. Just I can't wait until I don't need to carry around a lathe, brush serrator, who knows HOW many sets of brushes, springs, shims etc! Happy days!!!!!

RE: brushed motors - I got a 9x1 orion out today in my B4 and I have to say it felt much the same as my brushless 7.5 does now that I've been able to set it up to behave how I like it with the esc and radio. The brushed might just be a touch smoother though.. I think I'll give it a couple more runs but I daresay I'll end up agreeing with you.

Adam's brushed motor pit box is NOT light!

It's gotten heavier Steve, a buddy of mine from Illinois sent me a whole whack of brushed motor stuff 'cause he's not racing anymore. How are things looking for the long weekend race? I'm going to be back in town this Friday until the end of the month.

The brush motor does not develop near the torque and after one run you will also have less top speed . The performance keeps changing and just gets worst till you grind & new brush`s...

Personally feel brush motors never were as smooth or as fast as the new designs from brushless...


Try a smoother brushless , like a 8.5 or even a 10.5 and then compare those to your 9T brush...

Are the B4 driveshaft/cvd compatible for a B3 in length etc.
