RE: diff gear
 

did you make sure the gears meashed properly before you drove it???

2 other times we took it out no problems so i assume they were ok

With this sport/hobby you need to add blue locktite to all metal to metal screws, or the motor will vibrate them lose, including the screws that hold the motor down, the c cup grub screw's, if it has a 2 speed tranny in it the 2 way drive clutch grub screw's.

BTW- thats a spur gear not a diff gear. The diff gears are unadjustable and steel. Doubt you are gonna strip those :)

yes diff gears strip. It happens all the time. If your pinion bearing goes out, or if it is not shimmed correctly, you can strip a diff gear :) But yes he is talking about a spur lol
