as mentioned before, this is the on road thread, just an FYI.
With that being said, start with the obvious things:
1) Did your VXL ESC get switched to training mode somehow? That would be 50% throttle. Reset your ESC to normal mode and see if performance returns.
2) Check the gear mesh between spur and pinion. If too tight it will add heat to motor and overheat the bearings. Use a strip of paper between the pinion and spur to set the proper mesh.
3) If you overheated the motor, how badly was it overheated? A cheap temp gun is a must have in your toolbox. As previously stated, Harbor Freight has them for $10 or so. That would be adequate for what you need.
-if you really torched the motor, the magnets are probably toast and/or the bearings at either or both end of the motor. You can pull the black plastic endbell cap off the motor, then carefully disassemble the motor to inspect the bearings. You can replace the bearings if they are ruined. If magnets are weak, look for a replacement motor.
4) Check all 4 corners to make sure your wheels are rolling free w/ no binding. Friction is the enemy and will add heat to any motor. You want ALL of the bearings clean and lubed so wheels spin free.
5) Check the bullet connectors/wires. Make sure nothing is melted or wires touching from motor to ESC.
VXL will run up to 3s with proper gearing. Check in the manual for suggested gearing or the Traxxas website. I've never had a Bandit so I don't know what suggested gearing is. Check the rating of the 3s lipo as well. The Bandit is pretty light so anything over 30c is probably OK unless you are overgeared (too tall).
Good luck and have fun
