On the fifth flight of the day the Riot was on the ground, I opened her up to take off and the motor made an odd noise for a couple of seconds followed by a puff of smoke and dead stop.
Luckily the model hadn’t actually moved. Unlike Les on Saturday. His Riot was mid flight when a puff of smoke was observed followed by loss and control and total loss of the model.
Closer examination this evening reveals nothing physically wrong, apart from a strong wiff form the ESC! Motor was loose where it attaches to the bulkhead, not really bad but enough for some vibration.
Any ideas??
