Been following this since the start.
Guys not to sound like a jerk or know it all here but 8s????
These trucks are meant to be scale re creations of the real thing.
That would be like a real one of these having a top fuel dragster engine in it.
As far as the rear axle failures .....thats no surprise!
Those gears need to be set up properly they are nothing more then scaled down real thing!
If a full scale rear axle is set up wrong it wont last one pass with 800 plus HP thrown at it.
As normal with RTR's like this they need to be checked before bashing them.
If you want a beater then buy some sort of 1/8 Truggy set up.
Scale is scale!
