Fuselage molded "exits"??
Guys
I'm struggling to find the right word but basically I'm sure I've seen some neat molded items that you can use to route wires/aerials out of a fuselage neatly in an aerodynamic manner. Think they've be used on full carbon gliders etc to expose aerials to better RF. Does anyone know where I could find some?? cheers Mark |
I thought that Sullivan products makes one, but in looking for it, I found this:

Bob, thanks!!!!!
Has it been proven that a carbon fuselage reduces 2.4 RF quality when using solid systems such as FASST?? Or is it a myth that people worry about?? M |
My manual for the radio says to try and expose them on carbon fiber fuselages.

M I had a problem with the FASST receiver in my Exteme Jets F-4 in that as originally installed, I got shorter range during a ground range check than I was used to. It was still more than the 30' that Futaba recommends, but I was used to getting over a 100', and this was significantly less than that, so I was not happy. The receiver was right under the canopy/cockpit, so I put a plastic tube inside the canopy right next to the corner of the instrument panel and the side of the cockpit tube where it was not very visible. After engine start, I take one of the antennas from the RX and put it up the tube when I put the cockpit/canopy on. This fixed the problem and I get lots of ground range during a range check like I am used to, and the link has been flawless in the air. As I recall, there was some carbon in the fuselage layup that I saw before I painted the inside, but when I was building the plane I didn't think it was going to be a problem. On the other hand, there is a lot of electronics and wires around where the RX is, so maybe that caused it. I I was going to do an all-carbon jet with FASST, I'd probably build it up with the antennas inside as normal, but then do a thorough range check to see if there is any effect and have a plan in mind for how to get the antennas outside (or up into the cockpit) to deal with it if it is an issue...
