The screw is ok boys, the problem is the motor not spin very free, but is "forced"
400$ of regulator.....puff!!!
290 € of motor.........and is not worked
I mourn my BK XL :(

It is possible that your ESC, when it smoked, overcurrent windings. If the insolation is gone from wires then you will have the same effect on spinning as if you connect motor wires together.

Just a thought, unless you have mechanical problems...

Yes is possible, the motor infact seems spin like when the 2 cables are touched, less hard, but much similar one...
But i suppose the motor it had a problem, because 2 hour before the controller works fine whit BK 8XL,not as soon as mounted the lehner, two minutes and......puff!!!!
