I took my Revo out for the first time in a couple of weeks and something is terribly wrong. When I go to accelerate the truck creeps forward regardless of how much gas I apply. The engine screams but still the truck barely moves. What is wrong with it? Any suggestions as to what to do?

Sounds like the slipper or the clutch need a little tlc?? I had it happen in the middle of the race and burnt the whole center out of my spur because the slipper was to loose on my TMaxx-- not sure if the REVO is the same?

I think the clutch should be first on the list. Followed by the slipper. Followed by checking the diffs, crowns and pinions and the centre transmission. Then check silly things like grub screws etc.
