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!

Perhaps its overheating, even though you aren't getting close to the current rating. Just a thought.

my thought would also be overheating the ESC,.. however, I run a B40-L LMR on 10 zapped cells, with the 70 amp opto ESC,.. and a 13X13 carbon folder,.. which draws 84 amps. No problems with overheating in mine, even in a smart with no cooling provisions. I only have to run the motor 8 to 10 seconds though, as it's almost out of sight at that point

where did you purchase the motor and ESC? I'd contact them and tell them what's happening.

Thanks for the replys. I found out that when it doesn't want to start the second time, if I unplug the speed control and plug it back in, it works! I got the speed control from Aero Model. Any more help will be appreciated!
