Non moving Mini Inferno

[RoyalCBR]

I have a rather poorly Kyosho Mini Inferno (its my girlfiend's), and after a run in with a traffic cone and a replacement front suspension arm it doesn't want to move.

I have looked at the drive train and I am not sure if the issue is there. When the car is off the ground you can turn by hand all 4 wheels and everything seems to be turning smoothly. Plug the Lipo in and again off the ground everything spins nicely.

However place it on the ground on only the front wheels want to turn, then they give up and the motor is spinning but no traction.

I have thought that the chassis could be bent and the gears not meshing properly - any ideas?

Cheers, Mark
