There is another, slighlty overlooked, benefit of failsafe (whether it be PPM or PCM). Everybody talks about its protection against interference and 'returning control to the pilot'. These are obviously the best scenarios.

The standard setting of throttle to idle also has the benefit that it stops your model flying away (specially if you combine it with gear down and airbrake out). I am not suggesting it will allow you to get your pride and joy back, but in crowded areas like the UK it will stop the model from flying miles away ind injuring somebody. Although you don't want to lose your 10K jet I would much rather do that than have it kill an innocent person.

This can have its downside as mentioned earlier in the thread. A boy was killed in the UK when a model when into failsafe. I cannot remember the exact story but I think it involved copying a model memory which reset all functions to 'HOLD' and the throttle was not closed when interference was encountered.

Anybody who uses these things, please make sure you know exactly how your particular system works to prevent further tragedies.
