Crash of a giant scale folding wing F4U Corsair and Moki

Brian O'Mearas beautifully built giant scale Composite ARF F4U Corsair with folding wings powered by a Moki 250cc 5 cylinder Radial engine is totally destroyed when a wing folds in flight. Even the engine was destroyed with 4 cracked cylinders.
One of the wings did not fully lock in place and after 3 laps this beautiful 110" span Moki powered beauty was gone.
