That would be the Edgley EA9 Optimist, which I bring up here periodically:

I think the major mistake that they made (and I remember it being discussed
at the time) was not coming up with a two-seater (think modernized ASK-13) as
their first design. Even back then, there was a need for affordable
training gliders to replace aging K-7s, K-13s, 2-33s, and Blaniks.

We've spent the past few years designing and building an "affordable"
truck-based winch, making heavy use of CAD design and CNC fabrication, while
minimizing the amount of skilled labor required (machining and welding). We
start testing in the next few weeks. One big problem we're having is getting
hold of a decent training glider with a CG hook for testing and training. If
we want to get soaring back on its feet again in the US, we need a rugged
training glider in the 30:1 or so range that is affordable out of pocket by a
small group of people, say $50K (and, no, I don't think a clapped-out G103
with a 300 lb useful load is an option). It's time to explore lower cost
fabrication techniques...

Yes, that's it, the Edgley Optimist. Great looking glider. I think you
are right. Should have gone with a 2 seater first.

Best of luck with your winch project. I used to drive the winch for my
club, back when we had winch. Driving the winch was fun and gave me a
great sense of satisfaction. Of course, being on the other end of the
Spectra is fun, too!
