This has probably been addressed, but I wasnt sure how to search for this.

There have been a few guys at our field say "something is just crashing thier planes". They feel someone has a a way to grab their frequency and knock their plane down. I figure this is a common occurance, but they are afraid to fly. It doesnt bother me other than i have to hear about it and they want me to fix it, since I am the club pres. I also asked our nieghboring clubs about 30 miles east and west. They say the same thing happens at thier club every 3-5 years. One guy it happened to was a really good pilot, and he lost his 30% YAK, However he was flat spinning when it crashed. The other flies strickly electric and hitec, fair pilot. The main crasher uses used junk, and was asking for it, should be on a buddy box, but is hard headed.

We used AMA frequency checker about 2-3 years ago, and nothing was found. We also have a Hobbico freqency checker at our field. Anyone have a solution for this problem? Thanks Dylan F.
