thanks for the reply, a racer who knows a lot more then me about rear drive and ball diffs told me more then likely my diff was not built right, but in the rush of a race day we didnt get the chance to pull it apart so i think it is the diff, i know the last outing before a rebuid it went dead straight under power, but thank you anyway i will check my tweak, but once again if anyone has any diff building tips please feel free to share them.
cheers

Falling in love with driving my recently accuired 12th scale.

Questions:

14 gauge wire okay for 4.0 motor?

My purchase came with many tires, but pink rear and black fronts are the recommended tires for my track. Would truing and using grey/magenta/pink rears be beneficial to practice or would those compounds throw off the feel of the car. I dont see myself traveling to other tracks, so this quiver of tires is just taking up space. Basically, should I just donate them or practice with the extras?

Do you guys think 16ga wire is big enough for 1s/17.5?

hi guys, just searching for some advice, Between ball diff rebuilds ( which i am new too ) i am noticing sometimes i get it right and sometimes not, but i don't know the difference of what i am doing from 1 build to the next:confused:,. sometimes the car pulls one way under power generally left and sometimes it tracks straight, any hints as to what i should be doing during a rebuild or what i should be looking for or even where i am going wrong, any advice would be greatly appreciated.
cheers

A commonly overlooked cause to this is the left side hub being on too tight. You need to have a slight bit of play in the rear axle otherwise the rear bearings bind. Since both rear bearings are on the left side of the diff...it will cause the car to pull left.

ive heard of people using o-rings as spacers and a cushion for the axle? is this worth trying or not to bother. just stick with the little bit of play
