Recently one of the motors on the BKLi10 developed a fault. At first I thought it was a problem with the ESC so I replaced that.

When I then tested this, the problem still remained. The now pointed me to the motor.

Unfortunately when I tried further testing, a badly insulated USB cabled cause a short circuit and fried the Flight Controller. Thanksfully I had an old Aikon Flight Controller that I could use as a spare. I ordered a new motor and got everything soldered up. Everything is now testing OK and all being well I will get a few test flights when the weather clears up.
