What if the radio glitches?

A radio glitch is simply a temporary loss of control. This is generally due to a stray radio signal, either from the surrounding environment or from noise generated by your own power system.

Again, don't panic.

If control is lost, chances are good that you will regain it a second later. Try to move the sticks again.

If still no response from the airplane and a crash seems imminent, alert others in the vicinity by calling out in a loud voice (Lookout, Heads-up, Lost Control, I don't have it).
