My understanding is that these guys specifically DON'T want to fly at our club...the old story about not wanting to be part of an organized club and having to pay dues. However they are on county property; the guy from the county really perked his ears up when I talked to him about the liability issue; we are able to cover liability to the county as the landowner whereas rogues can't offer that up. If these guys were outside 3 miles I wouldn't be so hot on the issue, as well as the fact that numerous flyers at our club say they have suffered radio interference, but yesterday it happened to me, and I lost a brand new plane. As noted, I'll probably start switching over to 2.4, but these guys flying within 3 miles and darn well know we're there just really torques me the wrong way.
Thanks for the replies.
