I have mounted antennas on the inside of planes with no pronblem but did run across one that did not like it at all. I do mean 5ft of engine off antenna down range. I rerouted it out the side and up to the vertical stab. This increased it tremendously. I do believe it was due to the servos mounted in the tail and the long extensions running parallel to the antenna. Point in Fact. Run it where ever you want!!!!!!!!! Do a proper range test. The plane will tell you if it wants it there or not. [sm=lol.gif]
