Tarot 680 Crash.

I need some input here with this problem. I have a video of my failure below .


Tarot 680 Crash T-Motor MN3508 Failure? (6 min 53 sec)

Tarot 680 Crash T-Motor MN3508 Failure?


I had an unfortunate crash yesterday. I was in auto-pilot Then shortly after switching to manual control I either lost a propeller Or the motor seized up. (The motor does not work now but could this be because it was on high RPM's with no resistance as it was falling.


Either way a hexacopter should be able to stay in the air on 5 motors right???


I'll also mention that I'm using T motor MN3508 380kv on 6s.

I'm spinning CF 1355 props And according to E calc The Max power is 340 watts.

The motors are rated at about 310 watts continious.

I will Say that the Power per motor is approximately 100 Watts at hover. I have rarely if ever punched the throttle to 100%

I have less than a year into this hobby and I love it but I built this hexacopter to be a reliable platform. I have only owned these motors for about a month and I've already had one fail???

I originally purchased Tarot 4108 motors (That actually have a higher wattage rating) but from what I understand their efficiency and quality control is not as good as the tiger motors.

Am I doing something wrong or did I just get unlucky? Since I have to do a partial rebuild to fix it I would prefer taking steps to prevent this from happening again.

Any input Would-be appreciated.
