I run the motor, on 5s, without any load and it's smooth running up to a certain rpm. Afterwards, it starts screaming and I see sparks coming off the middle bearing area (the motor has 3 since it has a standoff).

I didn't notice this in the begining since I was balancing it on 4S.
This is supposed to be 6s(5 blade load) capable motor.

Any suggestions?
I thought you arent supposed to go past half throttle with no load on the motor,
The motor will spin faster than it's supposed to!
