I have heard similar singular whacking sounds come from metal rotors when pilots have 'horsed' them into the air before they were quite ready for fly. Even done it myself and heard it clearly. That sounds like Allan's possible explanation might cover this event too when the rotors are majorly coned taking the weight before full centrifical forces take over and spring them back to correct flying condition.PeteBairnsdale,Vic.

Birdy, You fly A.K. extruded blades don't you? If so how can the skins tin can effect? Just a question/statement for clarifcation from a puzzeled person.What you focus on grows. Des Gravin Bullsbrook Geraldton's (southern suburb) W.A.

Me thinks! Because the Rotors were loaded severely and trying to speed up while pulling the angle of the disk back and into the sudden thrust of power from the prop wash as full power was applied, the whacking sound would come from the Rotors hitting this Log (if I can call it that) of compressed or hard air from the prop wash that caused the loud banging sounds, a bit like a paddle slapping on water!!!!Jeff H-S
