I had to contact Futaba for a problem on my transmitter that was doing weird things and I got a new one. During the exchange with the tech. guys he told me that their 2.4ghz receiver are not that sensitive to vibration but they are sensitive to heat and so he said to not wrap the Rx in foam like you do with FM Rx and try to get air surrounding the Rx to keep it cool. Since, that I've change the way I fix my Rx in my airplanes and I use just a little foam attach different way depending on the airplane. For the antenna, I just use short pieces of fuel tubing that I glue on the side of the frame with a touch of thick CA. Then, I put the antenna into the tube where it stay. I try to get the last inch of the antenna out of the tubing.
