All wired up to the 80-85 motor on the bench I thought I would see how it worked if I changed the pwm rate from 8kHz to 12kHz. The motor with no load ran roughly for 2 of 3 seconds, having trouble keeping sync. So I disconnected the battery and programmed the 8kHz mode back in.
But the damage was already done When I ran the motor up again, it rotated erratically for a couple of seconds then the 16 guage battery leads I was using, smoked up and melted
It would seem these controllers are perhaps not as robust as they look

Since it showed no outwardly visible evidence of abuse, I thought I would try my chances of getting a repacement, so rather than butcher it about, i boxed it up to return.
