At several flying fields I have been members of heli's flying around were the norm, its those low flying heli's that buzz the field at 200ft or less, coming in from behind that you know are on top of when its almost too late. The location of our was close to the water with a wood between us and the water. You get a heli decididing to buzz you from there you have no warning. contacting the faa and the airport (6miles away) we were told that heli's had the same hieght limit as airplanes, and that was 500 ft, while we were limited to 300ft. Now you tell me that any heli can happily buzz rc'ers at will?
