Thanks to everyone for the help. I have a good idea how to run it in the wing now. Todd, thanks for the detail information. It sounds like you are checking the receiver range prior to installing it in the plane? I do this as well, plus all of my receivers and other radio equipment are test flown in a test plane that I keep just for that purpose, to make sure they are working well prior to installation in the expensive jets. I check at 4 points around the jet with engine off and recheck with engine running at the same 4 points.
I thought that the first time it happened that it might have been related to the antenna placenent, and it probably contributed to the problem, but after moving the antenna & range checking the second time and acheiving over 110 paces range I don't really think that there was a further issue with my installation. There were so many people having fail safe problems at Heart of Ohio that I relly think it was interference related at this point. I was actually able to verify interference problems with my scanner after switching to another channel the second day of the event. The pin for channel 17 which I was using was on the board and not being used and yet my scanner was receiving a maximum signal just as if I was standing there with my transmitter turned on...very scary!! Thanks again for all the help, Gary
