Car trouble
 

I recently purchased a tamiya tb-03. If I have the car off the ground everything works fine but as soon as I put it on the ground the wheels won't spin. I tried rebuilding the car but I got the same result. What might I be missing or what should I look at?

Sounds like it may be missing the pins that fit in the hex' s to drive them .

Or it could be just as simple as a loose pinion gear or the hexes are not over the pins properly.

check your diff out make sure they spin correctly or the pins for the diff yokes. :batman:
