Thanks for the report Dean,

Not sure I understand "...static current at the set RPM is about 135%..". Does that mean the current at zero velocity?

I believe we have the overhead required as I have done the Masters pattern never exceeding 2500 Watts and our batteries are getting better. However, I'm sure there will be conditions where we might need more power but we don't need perfect regulation. I agree the sensors might be the answer to the control problem. It looks like Futaba uses them in their brushless servos. I've also heard rumors they might have an RPM controlled power system coming.

Stay tuned, things just keep getting better, Jim
