I am running a Hacker B-40 LMR with a Hacker 70 amp speed controll. Static amps on bench are approximately 62 amps.

My problem is that after a climb out of approximately 20 to 25 seconds, the next time I try to turn the motor on, the motor will buzz and the prop will rotate about 2 revolutions and stop. If I turn it on and off 3 or 4 times, it might come back on. I do have the speed control settings on the Hacker recommendations.

Any help will be appreciated!
