I just maidened another wing. For power it had a 380 motor with 25a esc from bidproduct.com. Dirt cheap parts. And then a 3s lipo because that's what I had, and Google told me it should be OK for a 380... you might guess where this is going.
The motors come with some 7 inch props but I put in a push-on Gunther of 6x something inches, those white props that should work great on 400 motors.
I was not sure if the plane would fly at all, in my hands it felt sorta heavy and I was not sure about the center of gravity. But it flew! Just fine! Got it in trim, flew a couple times around the field...
And then there was a smoke trail. First I thought my eyes were playing tricks, but also a loss of power became apparent. Motor off and safe landing, run to the plane to disconnect battery.
Well. The lipo got pretty warm but is OK, after cooling down there was plenty of volts left. Apparently nothing was destroyed except the motor. Some white wisps coming out of it, disgusting electrical-fire smell.
Must replace it with a speed 400 I guess.
Was the reason here too high voltage? Would throttle control have helped, or was the motor doomed from the start? OR does anybody think the motor might be defective?
I have tested these motors with 3s lipo before and they got pretty warm but did work, and produced nice thrust. That said, this was the first time I really flew one.
