I had a weird issue today. I'm throwing it out there to see if anyone else has had a similar experience. After starting up my Trex 550e it started acting funny after about 1:30. It seemed to loose power slightly and then totally causing an auto rotation. Battery was/ is fully charged. I started up again and was testing the throttle on the ground. It was laboring occasionally and then all of a sudden it seemed the main gear locked up and took a couple chunks out of the main gear.
The one way bearing and tail gears are great. The blades slowed down very gradually and there was no drag or binding. The issue is either the motor, ESC or main gear.
After the lock up the gear messing seemed fine. I hadn't adjusted it in at least 20 flights and the motor was tight in position, it hadn't moved. That made me think it's either the motor or ESC. After realizing I've never serviced the motor and there is at least 2 hrs on it since I've owned it and who knows if it was ever looked at in the last 5 yrs, I took the motor apart and cleaned/ lubed it. All seems good, not much grit and the bearings are sealed so not much to really lube. After cleaning the resistance seems to be gone but I havent tried flying yet.
Do ESCs ever go bad and could stop the motor that fast or would something mechanical (grit or something) that could have caused the motor to bog down and then stop suddenly?
