<DIV><FONT face=Arial size=2>Those where fiberglass weren't they? We
are dealing with the c.f. composite planes causing RF interference.</FONT></DIV>
<DIV><FONT face=Arial size=2>This has been hashed over many times but It is
still an issue as Gray and I have both experienced carbon fiber fuse RF
issues on several different setups. The plane I flew all of last year is
c.f. but I had the antenna on the outside and it used kevlar pull line on the
rudder and c.f. pushrod with MK bellcrank with no RF issues. The previous
plane (same design and c.f. lay-up) was setup with metal pull lines on
elevator and rudder and I had a very bad glitching issue when I ran the antenna
back to the tail and on the outside too. I had to run the antenna out to
the wing tip to cure the issue. It is my belief
that the combination of wire pulls and running the antenna parallel to the
wires and the c.f. fuse where suspect as I tried three different receivers to no
avail. I guess the only way to have determined if it was the wire pulls at
fault is to have changed pull lines over to kevlar. It is
debatable since I crashed the plane (it crashed because of a failed pull line go
figure) before I could change the lines over.</FONT></DIV>

<DIV><FONT face=Arial size=2>Most of the Prophecys and Hydeouts that were
built by me had a DuBro antenna tube in the lower corner of the fuselage
between formers and the glass. The tubes were $0.75 each. They were put in
place with silicon adhesive. If not installed carefully, they could rattle.
Most had Dave Brown push rods and Pull-Pull rudders. I never heard of a radio
problem that was not a sick radio.</FONT></DIV>
