We seem to be doing pretty well for a rookie team because we basically have a driving mechanism that kinda works but has 2 problems. First, the gearboxes work but when we hook them up only one side works and the other just kinda starts then stops and continues to do this until we cut the power. Second question how can we mount and construct a tensioner to mount to the chain in order to keep the chain from slipping off the sprocket from the gearbox (we have a 4-wheel drive) Please help us
