Elad, Don has plans for a Storch. I think it's a 40 size. We'll have to get him to chime in on that. Also Bob Holman sells plans and partial kits for the Storch. I think they are larger, but they don't use very large engines. They'd be fun to fly, messing around with the STOL characteristics. I've wanted to build one, but I still have a few projects to finish before I take on something new.
