4200XL gearbox failure out of the box?

[thebigo]

Yes I see, have been through this before, one on each side and another again. Finally decided to go with the upgraded system of RC4WD and these work good. I think Cooper bought the upgrade to but he dident think they had the power of stock, but I sure do?

The stock ones are not designed to last with the torque and resistance of the tracks in dirt, they work for a while but eventually start to bust teeth, same with the turntable motor and planetary.

Really to bad this was already messed up right when you recieved it. Make sure you E-Mail them back about the problem they will replace the parts for free.
