I recently bought a custom hexacopter, made of carbon and size 800mm. It flied well 6 or 7 times.
Today I was flying in Loiter (with Pixhawk) and suddenly saw some smoke and the hexa began to go down. When I reached the place I saw one motor burned out and it was hot, the other 5 were not.
Triying to know the cause, the motors it have, Turnigy 4225/390kv are recommended for smaller frames like 650mm.
Could that be the cause? The motors are not suitable for a 800mm frame? The props are 14".
