We used the BB motor that came on the 64:1 gearbox to power our arm last year. We bought a 125:1 gearbox to get more reduction, then used it to drive a chain system with a further 8:1 reduction. This was used to raise and lower a long arm which gripped the tube on the end. It worked fine thru 2 regionals, and in demonstrations over the summer, and is still working. No smoke from the motor. We bought several replacements, but never needed to use them. Our arm was designed with a gas spring to support most of the weight, and we were always careful to not stall the motor. If you take these design precautions, the motor should be fine. If you treat the motor like a CIM, you'll probably smoke it.
