My recollection is that I've seen various posts about hacking the GB motors, at least some were not on this site... Basically they work like most other brushless motors w/ position sensors, except the GB motors position the sensors differently than most motors do... So to use non Invacare controllers it was claimed that you needed to make new brackets to hold the sensors, or replace them...
There is a fellow locally that does a variety of chair hacking, mostly making off-road buggies out of power chairs, and other cool but MHO not very practical stuff... One of his creations was a buggy using GB motors and big tractor tires, which probably wasn't great for torque... I got to test drive it, and encountered the same sort of issues that BM mentioned having w/ his chair... It was fast and fun once you got it moving but if you tried doing much at slow speeds the controller would overheat and shut down...

Want to make / get a better chair, ideally one that stands.
