So I’ve failed… Pretty Bad. Here’s the story… I lost a screw on my motor mount so I went and bought some new short M4 bolts/screws. I installed them with threadlock. The motor was still able to spin if I turned it by hand so I turned it on and spun it up just to check it was all good and disaster struck. It literally caught fire, there was a flame coming out of it. There was some smoke too. I immediately stopped it. After I spent some time just looking at it with my phone flash light through the small gap between where the motor gets screwed on and where the motor spins and none of the screws were touching any coils. The only other thing which it could have been is some threadlock had dripped down onto the coil and either shorted it or something… I’m not too sure. It could have been some vapour, I’m not really sure. I mean I know it would only take a slight brush of the coil against the screw to short out but I’m pretty sure it doesn’t touch at all. Video of it turning freely - nothing is catching and it feels like it should: https://drive.google.com/file/d/0B6MM3ijJmr69aXlJbC03cksyUlE/view?usp=sharing

Just wondering if anybody has any insights into this or thoughts on it… I’m going to have to buy a new motor but just interested…
