[PAR_WIG1350]

Although nothing can be done to prevent the case short issue with the 775s, the associated electrical issues can be completely eliminated if you have the motor totally electrically isolated. That means no metal gears, gearboxes, or structure in contact with the motors case, shaft, or pinion (if that is made of metal).
Last year, 1350 used 2 of them, mounted in two (PLASTIC) fisher price gearboxes, to power our main arm joint and they worked flawlessly. The FP gearboxes already had the appropriate mounting holes for a 700 sized can and totally isolated the motor from the frame. Also, torque wasn't an issue for the gearboxes at all. In one match, the arm got hung up on the rack and the operator inadvertently lifted the robot a bit; the point of failure was a 5/8th inch aluminum shaft and a small steel sprocket located in the multi-stage chain reduction between arm and the gearbox outputs. The shaft was bent and the sprocket broke into 3 pieces.
