despite the fact that I I have done thoroughly preflight checks all the time, my HotSpot delaminated during a high speed pass.
I saw pretty huge parts of the fuselage fly away, did everything to slow down imediately, the HotSpot seemed to be under control. I decided to cruise around for some minutes to burn fuel. I saw there was a wooden coloured part hanging approx 30cm below the fuselage in the air. I thought it to be part of one former or retract mount hanging on the airline. surprisingly the gear operated normally and came out. landing was fine, but after some meters the engine quit and the plane was dead, without current.
as I approached the plane, I realized it was the reciever battery pack that was hanging out of the plane. on touch down one wire ruptured.
thats what I call luck!
