We used a 5:1 36mm reduction on our shooter last year. As I recall we had to cut a little bit off the FP shaft to get the motor to fit snug without spacers... so the 36mm gearboxes probably have enough shaft length to add a few small spacers. We did find, however, that ordering some extra gears to press on to the FP made life easier as we cracked them pulling them off the banebots motor.
As for overheating... well, we did smoke one FP in Portland after running it for about 10 minutes straight, but after adding a heat sink to the motor for Toronto we never had any problems with it there. We NEVER had a problem with the gearbox... mind you, it is quite possible that quality may vary. Having a spare gearbox (with a spare FP mounted on it!) on hand at the competition is cheap insurance, especially for critical functions.
Also keep in mind that FP's are thoroughbreds, not draught horses... they need to run, and run fast.
