Let me see if I understand.......
30% or larger airplane with a 20+ inch diameter prop, plane is hovering at eye level in front of a crowd of spectators or worse yet pilots busy flying their airplanes on the flightline. This is safe right????? I don't care how much skill you have as a pilto or how good you think you are airplanes can break, radios can fail and what do you have a flying meat cleaver that can go into the pilot's stations. I have nothing against hovering, I can do it and it is really not that big a skill. If you must hover why not do it well on the far side of the runway instead of right in the face of spectators.
