FrSky R9 Receiver Mount

Thread a long zip tie lengthways through the arms to run the antennas along, then thread smaller zip ties through the arms sideways to secure the antennas in place on the arms. Use heat shrink and other materials to hold the antennas firmly to the long zip ties further along. The idea behind the notch at the bottom of the arm is that you can pull the arm up slightly until the notch clears the hole in the base, then fold the arm flat for transport. This relies on leaving enough slack on the antennas or attaching them loosely enough to the arms so they can slide through as you fold. Assembly requires a M3 bolt and nyloc nut, plus VHB adhesive to stick it firmly to your model.
