Fail-safe settings for control surfaces

[Grow Pattern]

Larry,
           I use your #1 setting. With the addition of the retracts (when a 
plane has them) being set to "hold". Wheels going up on the ground hurt the 
prop and free flight landings with the wheels up usually do less damage.

When I get in-flight glitches the throttle burp and a trim change tell me 
what's going on. usually it comes back under control the closer it gets.

BTW PCM does not handle RF interference in eth long leads to the servos, so 
even with PCM set you can get wayward elevator glitches without a matchbox 
device or equivalent..

Regards,

Eric.
