make sure your screws aren't to long, if they touch the windings that will cause a lot of heat and ruin the motor. If the esc and battery are still cool and the motor is hot it may be undergeared. You may have some binding in the drivetrain, and it may be your driving style as well. Another thing is that your center diff may need thicker fluid, you may be unloading the front tires and causing the motor to rev high which would cause heat. Seeing that your getting hot with either setup I would look into the mounting screws, diff fluid, and drivetrain binding
