I,ve find, if you just set and talk with them a while and not get in their face right off the bat . Then during the B.Sing mention the club is strick on flying pattern and calling out low passes , etc. And if you see some one with a trainer , cut them a little slack. More times than not , this works. If not, I turnit over to the safety officer.
Heli,s out number planes at our feild 4 to 1 . After flying with them for the last 4 years ,we have all learned to respect each other, and worked out ways so everyone gets to flyand enjoy it. But it has not been easy. I just cant fly a plane when there,s a .90 T Rex 700 flying eye level , 25 ft away, so I just wait my turn.
