If the motor is running fine and you can't transmit power to the wheels / it's only moving weakly without resistance, it sounds like you have either a problem with your clutch or a loose flywheel. Pull your motor and check to see that everything on the motor shaft is tight and properly assembled, and see what kind of shape the clutch is in.

also check to make sure the brake disc is not melted and stuck onto the brake pads since the brake disc is made out of plastic. I would upgrade to the fiber brake disc if this is what has happened. This happened to my RS43 years ago. I would check this first before checking the clutch and flywheel parts since this is easier to see and take apart.
