This subject comes up every so often. The KR-1 is the only KR that had an extended wing option known as the KR-1b motor glider. There were very few built and to the best of my knowledge, none flying.
One could build a set of long and short wings for their KR-1 and make them interchangeable. If it only had the long wings, the KR-1b could be licensed as a motor glider or amateur built experimental. If it has the short wings, it can only be amateur built experimental. I believe the retract gear would preclude it from the ELSA category, but with the KR-1b wings and fixed gear, I suppose it could fit in the ELSA category. Licensed as amateur built experimental with fixed gear, the plane could be flown with the KR-1b wings by a light sport pilot as it meets the performance criteria. With the short wings, it would require a minimum of a private pilot with a valid medical to pilot.

Removable is understood by me to not be abused, and may ease in transportation ONCE, and then to be left alone - I agree. Is it feasible to have a set of glider wings to put on for a month of slower powered glider flying, then put the short wings on another month? Maybe some opinions are to leave the glider wings on, and callit a motorglider, but thats what I'm posting for. Should it be this way? Does anyone trade out wings for different flying? andy ____________________________________________________________ Need Medical Insurance?
