I have a hexa, built it in November, and have been flying it, I would not say it has a lot of time, I am around 10 hours - 50 flights, the motors are Tiger 3515's, esc's are Maytech 40amp opti's not bec (power pin pulled to the flight controller on all ESC's) , and the flight controller is a WK-M, the receiver is a jr DSM 2.4, along with the transmitter jr 11x24
After a flight today I landing the helicopter and shut down the motors. all the motors except m4 shut down, the m4 started twitching, the longer it twitched the more is started to engage. I looked over my transmitter to make sure everything thing was cut back to shut down point. About 10 seconds into the twitch the motor started spinning on its own, about five seconds later I was able to unplug the battery.
Immediately I started to look over the motor to see if anything was not right, I touched the esc and it was cool to touch, while the motor itself was hot, and it had a burning smell going on.
I pretty sure the motor is gone and I am not willing to fire it up to see. However I can also feel when I spin the motor by hand its not as magnetic resistant as the other motors are.
I have not touched it in any ways yet, but after looking at the esc/motor bullet connector they were all fine and way from each other, the esc power connections are solid.
Any ideas, I am wondering if anyone have had this type experience/ heard of it before, if so what was the problem, is it something in the motor, ESC, Flight controller.or else where.
Since it build in November the copter has flow great, nothing to report in out of ordinary situations.
Look forward to hear from you all.
thanks Jack
