Something that "snaps" in place will transfer vibration to the RX and that is a BIG no-no. Wrap in foam. Antennas (only bare part counts) can be routed into any small non-conductive tube. You can get these at McDonalds or Burger King. They call them "straws". A section of ny-rod or similar works too. Epoxy tube to fuselage and THEN insert antenna.
