I appreciate all the replies through the newsgroup and email.

I stand corrected. Apparently, my "vague notions" about the Strojnik
were wrong. From what I've been reading, the Strojnik S2a was very well
engineered, with some significant cleverness in the aerodynamics of the
wing, and handles well. The designer, Alex Strojnik, did gold distance
and more in his. The NTSB only lists one accident for the type, a hard
landing, and there were no injuries to the pilot.

Reviving an ancient thread.
I'm hoping to find plans for the S-2 or S-2A but they are very rare.
My intent is not to build one per the plans, but to use the plans as a resource and inspirational guide for building my own motorglider design which will be a battery / solar-powered FAR-103 legal ultralight .. project working name "Sunriser."

If you know of anyone who owns a set of S-2 plans, or even a project plane, please share their contact information with me.

Alex Strojnik decided to cease sales of plans for liability reasons, even though he passed away many years ago, I respect his wishes and his widow's.
John Washington of Reaction Research still sells the 3 Strojnik books, which are very interesting and helpful, but some essential details are evidentally to be found only in the S-2 plans.

BTW, the new link for the Strojnik S-2 on the sailplane directory is: http://sailplanedirectory.com/sailplanes/s-2/

Here's a little more info, but not much:

https://en.wikipedia.org/wiki/Strojnik_S-2

I would be very suspicious of the quoted 34:1 glide ratio, given the large wetted area. The 28 hp engine would only be (barely) adequate for self-launching at sea level, assuming it still runs (engines this old are problematic).

My advice to your friend: pass on it.
