Former N9681Z, but when the aircraft was deregistered just its old registration N5K was retained (behind the folded wing). During EAA Airventure 2024 presented in the home builders area.

A rare homebuilt aircraft that features a rapid wing-folding mechanism to enable trailering or storage. The wings are quipped with a quick release mechanism that allows them to be folded and locked alongside the fuselage in 15-30 seconds. There is a small sideways seat in the back that allows for a 150lb/68kg load (luggage or person). The prototype was donated to the EAA museum at Oshkosh by Ray Stits in 1969.
