Well at least we know what color the motors are now when they are naked .
Why on earth the esc didn't give out and destroy its FET's before that happened I don't know!
That person ran the motors to long on a hot day. Or it shorted like hooking the neg and pos together. I dont know why dji doesnt give you a heat detector with your purchase. Lol. I have not seen that before btw. Nice post!
That is very strange. The motor should have died if it shorted. I wonder if the melting was caused in the final decent. That is if the bird didnt crash. I burn a lot of battery in landing. So if the motor was on its last leg of a long flight it could have overheated during landing. Lasting long enough before it burned through the brace fully. That is some resistant plastic.
