Here's one I actually built. In 1982, I worked for Douglas Aircraft Company for a few months (college co-op program) and
lived just a block or so from the beach. A lot of guys flew slope soarers above the beach, so I threw this thing together to
join the fun. Well, "threw" is a good word, because on the first flight I threw it over the cliff, but forgot to turn on the
switch (dumb!). Luckily, it was built straight and it arced gently down into the sandy beach, no harm done. It provided a lot
of relaxing stick time.
