YOU AGIAN

okay this i can help. its one of several problems one STOP TESTING if its making noises and not moving you have alot of power and you dont know what its doing it should be okay but still.... okay so check you speed controllers and tell me if you are using a gear box and your wheal layout in relation to how their being powered (chains, which wheals are powered, ect...) chances are its an electrical or mechanical problem.
