I`m trawling through any RC heli related forums on a quest for knowledge about Heli Soaring. i.e. Flying a heli without the aid of on board power and using the wind / up draft to SOAR the heli. I came across this thread and remembered a link I found a while ago which may be of use to you.

But while I`m here,
I first heard about heli soring over on RunRyder a couple of years ago but never really thought I would try it for real until a few weeks ago. Over the last couple of months I`ve been trawling through the web in search for any further info on the art of heli soaring, but I think I`ve found all the sites there are on the web , on the subject. Half a dozen forum threads and a couple of pictures. I`ve started a few threads of my own in the hope of drawing in some interest and hopefully more knowledge but hit a blank. There are only a handful of guys worldwide who`ve tried heli soaring but don`t have much info on it. So I aim to change that. I`m getting in some practice on Reflex, (now that I have downloaded the new Vista update on my laptop.) and have some captured sim time which I`ve uploaded to YouTube for all to see.
My next task is to find a suitable site to try this out for real using my Raptor Titan and pick a day when the conditions are right.
I plan on using my heli as is for the initial trials. I.e. with the engine in and running for take off , bail outs and landing. For the soaring part, I`ll flick it into idle.
I`ll be logging anything I think will be relevant like heli weight, blade make and size, wind speed and so on. I`ll have someone handy to video it all and if all goes well, I`m going to build a web site and publish my results. I`ll get a forum going and add new info as it unfolds. Stuff like how to launch without an engine.
Cheers
Luke
