Another option is to avoid the FP gearbox entirely, and use a banebots gearbox. There are threads on CD devoted to adapting the FP motor to the BB planetaries, and while it is reported that the very high ratio BB gearboxes will shred themselves if you drive an FP all the way to stall we used a 5:1 on our shooter last year and it worked great. (The shred at stall issue isn't that big of a deal... remember that if you stall an FP it won't be around for long either... there are also threads here on "magic smoke".)

The FP with a BB planetary mount up just like the 64:1 Banebots motor in the KOP this year. Depending on your design it might be a quick and easy alternative to the plastic gearbox. Not that there is anything wrong with the plastic gearbox... I just wanted to make sure you were aware that alternatives are available.
