nothing crazy....you have seen the video,after the batch of wheelies it just snapped!!

its the engine,believe it or not i have never broke a gear in my life,the car has no week point what so ever,it is very powerfull and heavy so i presume something had to give.

im actually convienced now that maybe a screw or two had came out of the gear/adaptor and caused the gear not to line up properly ....hence the snapping gear..

this is my only feesable theory.
i have build l/scale cars/trucks for years and never had this happen.
