Just got my rampage mt and started to do the breakin last night. Things were going fine until the truck just stopped like the brakes were locked. Checked it out the the failsafe hadn't engage the brakes by mistake, though the lever was very stiff to move. I let it sit for a few minutes and it started and ran with no problems again. It went about another 15-20 minutes and the same thing, except that this time there is some smoke coming from the clutch area. I am pretty new to RC and this is my first gas powered RC, so I hope that someone can shed some light on this problem, before I start taking things apart this weekend.

I should descride what happens. I was driving an 8 pattern on the road when coming out of a corner the truck started slowing despite that I was calling for more throttle. It came to a stop, I could hear the engine reving as I gave it throttle, it would try to lurch forward but would not move.
