I'm not tired, but I have tried it (almost).
I have a MAC Shanghai fitted with a 1000w BMC gearset and freewheel - the result is basically the same.
I have a soft-start 18 FET infineon, and well, it works, but there are issues. There is some sort of stall protection which cuts out the controller at slow speed..sometimes at medium speeds. Cycling the power changes the sensitivity of this protection - it's mental.
I also have some minor shudders at low speed. They were major shudders till I upped the phase current.
Full-throttle, with the same motor and a newer 12FET infineon has no such issues.
I now have an 18 FET Crystalyte controller, which low and behold is an 18FET infineon inside. I will try it shortly, but hope for similar results as the 12 FET.
18 FETs is way overkill for this motor.
IMO 30 amps is about the limit for this motor, and the 12 FET will do this with ease.
If you run 50A into the 1000w BMC it will die. Despite the marketing, the mechanics of the motor are not up to it (yes I have a different motor, but the reports on the BMC show similar flaws). The Freewheel assembly, the axle, even the stator, all start to fail at high amps.
