ok today I picked up what I thought was a good working e-revo vxl. the thing has MAYBE 2 scratches on it so by looks it seemed ok for the price......20 bucks. Well I get it back and charge the battery up a bit and realize it has a problem. when I give it throttle it barely moves but makes some odd noises but when I hold it up it seems to spool up just fine. My wuestion, should I return it to the store I bought it at and buy a brand new one instead or should I just fix this one? What do I need to check? i've messed with a couple nitro stadium trucks and mine kept strippin out the spur gear so I took the housing off around the motor and they look fine. What else could it be?
