I didn't even think of removing them as I was only intending to check a setting on the gyro. When I powered-on I immediately heard one of the elevator servos whining, I checked and noticed the cover was binding one servo from centering. I tried to correct it but the cover was being held pretty tight. So I turned the plane off and removed the covers. I have tested and tested the servo and it seems to work fine. I didn't notice any dreaded electrical smell either.
- Has this happened to anyone else? or am I just lucky...
- Should I be worried about the servo?
- Are there any tests I could perform to reassure myself it's unharmed?
I've seen a lot of servo stall and torque tests on servos, this is a JR 8911hv, they seem to hold up to abuse pretty well. There is a little play at center when powered-off, but I'm pretty sure that was there before... ugh...
Anyway, plz let me know your thoughts and recommendations. I don't want to fly a potentially unsafe or compromised setup.
Regards,

I used to sell servo's but limit myself to just suppling locals with what they need to get in the air or finish a project. Servo's stall when they go beyond the limit of the gears - sometimes the pinion gear or driving gear gets damaged but the small amount of damage will likely not affect the performance of the servo. BUT whatever caused the servo to move beyond it's preset limit may still be there. I would swap that servo with one that won't cause a crash like the throttle servo or replace it completely til you can more thoroughly check it out.
