thats a nice looking truggy u have there. i think u should get a new battery for your box and u will be fine. that box is a starter / bump box not a roto start. there should be a screw on the top plate of that box. when u find it just take it out and u should be able to open the box. and u will see the battery in there. either order that battery onlien or go to the local hobby shop and get a new one OR if that box has leads on the side u can hook it up to a car battery which is alot better IMO. hope i helped a lil bit
