Look at an FES sailplane - simple. Much simpler than a towplane,
and much
easier
to schedule when you need a launch. I was part owner of a
towplane for
years, and
it caused me more grief each year than the self-launcher I now
own. And
then there
are the avoided retrieves - simple and priceless!

Are we really having this conversation after all these years, with
80% of
the
gliders going out the factory door with an engine?
