N5K has been used to register several different experimental aircraft designs. My three photos of N5K, a 1952 Stits SA-2 Sky Baby that is a de-registered Museum aircraft need to be moved to the proper N5K heading. I have been unable to do that, despite correcting photo captions.
At 7' 2" wingspan in a stagger-wing configuration, the Stits SA-2 SKY BABY is the World's smallest flyable airplane.
