Is the RC10B4.1 good for beginners? How much is it?

where do i find the anti-squat shims at on my cars? t4 and b4

They are located under the front inner hinge pin mount of the rear A-arms. The mount forms the back wall of the battery cup under the shock tower. you should have a 1 degree and a 2 degree and can stack for a total of 3 degrees.

Yea, I've done it. Works real fine with that motor/esc combo. I also know other people that have done it. They tried it with a 3S LiPo and that was complete overkill.

This motor and esc will work fine,the motor is around 3300-3500kv so it would be considered a 13.5.(feel free to correct If I'm wrong)The only issue that you may run into is the footprint of the esc is larger than alot of esc's ...so mounting in the b4 may be a challenge.Other than that If you have an adjustable/tuneable radio you can dial in/out braking and throttle.As the vxl esc is not programmable,some people are running sensored motor's with them too.

Well I've never seen a b4 closeup but it looks like there's room on the sides of the chassis. Unless height is a concern. I know my academy sbv2 body hugs the chassis very tightly. Not much room. Yes the traxxas is a 3500. Isn't 13.5 what most 2wheel buggies race with? Will be using 2cell lipo. Will be using a dx3s for the controller

the traxxas motor is pretty much a 10.5......and thats what most of us in michigan use for a mod. 8.5 or 10.5. not to many people run under 8.5 or above 10.5

IM having a hard time controlling my rear tires from spinning and doing doughnuts. What are some suggestions to get the rear tires gripping better other than the obvious suggestion of different tires.

couple questions. when and how often should I rebuild the shocks? When rebuilding; do I install all new internal parts or just clean and reinstall original parts?

Replace all the internal parts , don't reuse any of the old ones.
For your best performance , replace the seals after about 7 to 10 days of use...
