Fail-safe programming

       Remove this ad - become a site supporter!
The Survey thread triggered an important thought for me...

How do you program your fail-safe?

My Choice:

Throttle to low idle (clutch disengaged), all other channels to hold.

My thinking (not original) is that this setting runs the best chance of reducing intertia in the head before impact....

When I was learning to hover, I used throttle to idle with sticks centered. Was hit once and the heli autoed safely by itself (best auto I've ever managed ).

Any other thoughts?

This is what I do also. If your heli is the source of the interference it is a good chance that the interference will disappear once the engine is at idle. If it persists you can hit hold and get it down in one piece.

I hear some people put cyclic control to failsafe to neutral. Unfortunately these are not planes and do not self right themselves. I hear people of people that set collective to zero pitch. This may make it come down slower in certain situations but not all.

I do not like having set positions for any other control as you have no idea when a fail safe event will happen. If you are low to the ground and you go into fail safe the last thing you want is for your cyclics and collective to change on you with your knowledge. Instinctively you will try and fight that command and you will get yourself in big trouble.

With having all channels hold you are not scared by some violent maneuver you heli just did all by itself. You are just informed by your engine going to idle but the heli maintains it attitude (for a short time anyway). I feel this is less stressful for the pilot and gives him a better chance to save the machine.

Loss of Signal

Morning all

I thought I has responded earlier. In any case my throttle goes to idle. Some control is no control with helis. IMHO
