Troy, It definitely is a carbon fiber Prophecy, I bought it used (but never flown) by a fellow taking a break from pattern.
The problem is definitely related to the plane. Early this year I had a really bad failsafe and a bunch of lesser ones - at that time I was on 6 meters (ch 03) and was so convinced that it was a radio problem that I purchased a new 9C on 03 (I was using an 8UAP PCM on 03) - oops same problem must be interference. Nope, used the AMA scanner for 2 weeks and no interference !!! For the record I am an advanced class Radio Amateur ergo legal on 6 meters (50 Mhz)
So now I tried going to ch 53 (bought a synthized tx & rx module for the 9C --- this is getting expensive). On ch 53 the results were much better still a rare glitch but very seldom. I have checked the radio system range - all 3 receivers and transmitters are good.
The different results between ch 53 and ch 03 (6 meters) implies the problem is rf related. With all the metal pull-pull cables (6 of them), the pipe and the carbon fiber and the antenna running along the bottom of the fuse to the tail wheel --- I believe the metal pull-pull cables are a major factor.
Any thoughts ?
Thanks,
Paul

Paul,
where did you get a Carbon Fiber Prophecy? I don't know of anyone that ever produced one? The prophecy was produced by Dixie and then turned into Piedmont and now I think PAC has the molds. Unless somebody made you a special one your fuse is Fiberglass.
I would say you having else going wrong. I would look at another problem...I even run my antennas internally in the fuse inside an antenna tube.. I have flown Futaba for many years until about 99' and then switched to JR and never had any problems with either one. What radio are you using? Maybe you are having trouble on a specific Freq in your environment or maybe there is really something worng with your system. I send my radios in every single year and have them tuned up and tested. Its rare that they find anything wrong. But sometimes a weak output on the module or something like this...its gets fixed and I don't have troubles.
I have always used metal cables...and this combined with CF pushrods on the DEPS system I have never had a problem.
