We use the helical gearset in the black box first provided

Are you sure that your transmissions are locked in low gear? As the earlier message said, the white collar should be pushed forward toward the front of the transmission (where the drive shaft comes out).

It might be a good idea to find yourself some smaller wheels, but be sure that you will still have enough clearance on the ramp.

Also what do you have on your other wheels? We were popping breakers in high gear (using the black motors) when we turned and found that we had to reduce side friction on two of the wheels by adding cable ties. (We have 4 wheel drive.) Basically we couldn't turn in place in high gear until we added the cable ties. Even then, we can't just sit there and spin in place for any length of time. The breakers start to pop.
