There are loads and loads of good model sailplanes out there. And as the new stuff comes out, people upgrade and sell their models at good prices. In just the last few weeks, I've seen some very nice Graphites going for very good prices.

As to your conversion idea, it would very much depend on the plane. Which did you have in mind? Some of the 2 meter F5J type planes are extremely delicate - probably way too delicate for a winch launch.

I've been looking around for a spare plane for non-competition flying but it seems that there aren't that many sailplane designs around these days. With some exceptions all that seems to be available are TD competition ships in the two categories "ultimate" and "last year's model" and reformulated built-up beginner's polys such as the BoT.

There are quite a lot of self-launching sailplanes out there, though, and they're quite competitively priced. This has started me thinking whether anyone has had any experience in converting one of these for pure soaring. The only unknown for me is how the wing would react to winch launches.....in an electric configuration such a plane would be carrying significant extra weight which will stress the wing as the plane maneuvers but I doubt if the forces would come close to what could be achieved winch launching.
