Seems rather insane to feel the need to operate an RC Airplane at frequencies that are known for ducting/skipping and actually being somewhat functional in NLOS conditions - it screams "I want to be interfered with!". 2390-2400 MHz seems about the right place to run an RC airplane thats not actually a "drone" - and the spectrum is practically worthless for anything else except linking LOS repeaters and data work and even then its fairly rare.
