Futaba 2.4ghz receiver in a fuse with carbon wing tube
Just like to know the shortest "safe" distance a Futaba 2.4ghz receiver and/or its antennas should have, to a carbon fiber wing tube. The wing tube is about 1" in diameter and 34" long.
The fuse itself is wood.
The futaba 2.4ghz Q&A recommends exposing the antennas outside in a full carbon fuse. The Q&A does not mention carbon wing tube.

Just think in terms of the line of sight from the Tx to the Rx. with the Rx behind a Carbon Fiber Wing Tube, there is one angle where the Wing Tube will be between the Tx and the Rx. The same is true, to a lesser extent, with a large Gas Engine.
Do extensive Range Tests, on the ground, 360deg around the aircraft, and look at the results. If you have to, mount the Rx as high in the Fuselage as you can.

Keep the antennas away from the wing tube itself and arrange them to minimize the potential for the tube to shield them from the TX antenna and you should be fine. Loads of people are flying giant scale planes with CF wing tubes (great big ones in 170cc size planes) and planes with CF weave in composite fuses using the FASST system with no ill effects.

A few inches away should be more than adequate. I have them in my 50cc Edge, 50cc Sukhoi, 150cc Edge, and a teeny tiny 40" Yak (
), all with carbon wing tube and haven't had a problem. Keep in mind that 2.4ghz doesn't like travelling through metal either, so no matter what your wing tube is made out of, it's a good idea to keep the antenna ends a few inches away from the wing tube.
