I'm glad you agree your seeing the light. I have sloped the autogyro and my gliders off the hill read dump on Banwell long before there were all the houses there. The longest flight with the autogyro without using the motor was about 12 minutes. Strong wind right on the side of the hill lots of down elevator just stayed in one place moving it left and right on the face of the hill about 20 ft up.

How does a heli auto rotate? Negative pitch nose down for forward motion its called a glide path even though its steep and if the air going up exceeded the sink rate what would you be doing??????? Basic aerodynamics and theory of flight might help you understand the principals in action here however I don't have the time at the moment to explain things. For your edification.

Re: RC Helicopter Soaring

What is this a late April fools? Helicopters have nowhere near the efficiency of gliders, there is no way you can soar with a helicopter.

"soar", definition by Webster: "to fly without engine power and without loss of altitude".

The sink rate required to maintain head speed during an autorotation is considerable, it would take one heck of an updraft (read upside down microburst?) to sustain the T450 in an autorotation state.

Re: RC Helicopter Soaring

I don't know, guys slope soar with all kinds of scale models: jets, warbirds, whatever. With the motor / tail rotor / belt / gears removed, the heli should be pretty light. 450's are very difficult to auto, but if you could get rid of all the power crap, it might just work. You could use a smaller 2 cell battery and get the weight down even more. Even then, I'd have to see it to believe it.

Good thing this is RCCanuck's project and he'll try it. I for one am awaiting the results of this experiment. Go Johnny!
