Doug, my thinking is that there is no way of knowing if the preset failsafe setting are actually good without an airborne test. I could be wrong. Yes, you could test the failsafe mode with the plane one the ground, but that doesn't give me much assurance that the presets I have assigned to failsafe are going to be useful in 'saving my plane'. I gives me shudders to think of disabling my Tx in flight to observe what happens when the receiver goes into failsafe mode.
I may do some tests on the ground to see how failsafe mode reacts under the test scenarios you suggest. It won't tell me what my plane is going to do in the air, but it will be educational from the standpoint of determining how the system works under real interference loss of signal conditions.
Thanks for your input. I hope someone else has some additional input on this. Most of my planes are standard FM/PPM so if I lose signal, it's whatever happens. And I don't have any of the newer, fancy PPM receivers. So far, I have been lucky and never lost a plane to serious interference. I may have had some glitches, but they weren't fatal. All of my problems have been due to a short between the ears.

Couldn't you do it with the plane on the ground? :)
Another test would be to retract the antenna and walk away with the plane until the failsafe enables. Or turn on another transmitter on the same frequency.
