Lutach,

What timing are you running now, when you see the temperature problem?

I'm kind of skeptical that a 6 pole 9200Kv motor will ever work really well -- the commutation frequency is so high that the recirculating currents will never cease -- there will be recirculating currents running through all three phases all the time.

I don't know where the best timing would be for that kind of motor. I'd think you would need to set the timing kind of high, but I'd need to look at it with an oscilloscope to be sure.

Patrick,

I have the timing set to normal. Let me know the best timing for this little high RPM motor.

Regards.
