help me...please
 

I am new to RC'ing so I don't know much. I am the proud qwner of a volcano sv.
unfortunatly it doesn't want to move when I hit the throttle. only when I lift it up will the wheels spin. it's not the tranny, drive cups or dog bone. I'm thinking it has to do with the spider gears in the rear diff, but I'm not sure.

Any insight into this problem would be greatly appreciated as I am losing valuable run time :(



thank you in advance for your help

small nut on the slipper clutch on the spur gear may be too loose

I had the same problem on one of my trucks. The adjustment screw for the slipper backed out a bit. Two second fix.
