few days ago i took out my stampede and do a little clean up with WD40. today i took it to bash, it doesn't response like how it used to. the motor is spinning and everything but there is a whining noise, kind of like the motor is spinning but that spinning doesn't delivery to the wheel. its not as strong like it used to be. But when i pick up the truck give it throttle it spin but there is no whining noise. can someone please tell me what is going on? i also did a little adjustment tighten/loose up the clutch but it did not help.
any help is greatly appreciated
