I am pretty new, and have just got a mini e-revo for my 8 year old son. First day he rode it full speed into a wall, broke the chassis, steering arm and bulked. I have just ordered the new parts and installed everything on the new chassis. I then also put in a center diff (had no oil so added 50k). I have now noticed that the servo gears also stripped, so new ones are on order.
I also added thicker shock oil and stiffer springs.

I read the following post,
I am just wondering, why do you need to shim your diffs? Is it to enable the teeth to fit together tighter? How do you know if it needs to be done?
Also, when attaching the motor to the slipper clutch gear, how tight must the fit be? I read somewhere that I should put a piece of paper between the teeth, but when I do so, the teeth don't catch, they just slip (i.e. too far apart).
