I have only heard the term "plank flyers" from heli pilots. Any time I heard a heli pilot using the term myself, he was using it as a derogatory term as if flying airplanes was a sport that was beneath him. The only comments I will make to this is that hopefully not all heli pilots have that attitude. I can appreciate that flying helicopters is supposed to be about as easy as balancing a bowling ball on the sharpened end of a pencil and that the equipment is much more expensive than planes. My attitude: As long as an RC pilot is having fun, I don't care what he flies!! As far as my other club members, I just call them flying buddies!
