So i have been having problems getting the gearing on my e maxx to be right, for some reason now the car won't move, i thought it was a problem with the spur gear or slipper clutch so i bought new slipper clutch pads and a new spur gear..well i am still having the same problem...it's hard to explain so i took some vid's..sorry not the best vid's but i think they help


in this video i have only one motor's pinion gear meshing with the spur, the other is not contacting it, as you can see the car does move with the spur gear and pinion gear's on the motor...although not very smoothly..

now in this second video both motor's pinion gears are meshed with the spur gear. As you can see the car does move but none of the gears move. just the shaft and the lock nut at the end of it..

so what is going wrong? i took it apart and reasambled may times but can't figure it out..i will bring it to the shop to fix it but only as a last resort..thanks for your help!

I can't get the vids to come up , but if the shaft/nut is spinning with the truck and the gears are not then it is in the slipper itself since the slipper clutch locks the spur gear to the input shaft.

thanks for your input but a post on another forum just gave me the answer..it turns out one of the motors is lockd up...
