Circa 1927, Mathew B. Sellers bult and flew multi-plane gliders. These gliders flew well and Sellers went on to fly a steped, quadraplane glider in which each successively lower wing was spaced a chord behind the leading edge of the upper surface.

The S-1 Airster designed by Bert Kinner was a folding wing, side-by-side evolution of the Kinner Sportster. First flying on 1 May 1933 (piloted by Lee Brusse) they received ATC 521 and were priced at $1,985.
Two were built as S-1, NX217Y and NC13702, and 12 as S-1-A, NC13743, NC13746, NC13792 to 13794, NC14227 to 14232, and NC14293.
ATC 2-451 was received for gross weight change on prototype NX/NC217Y and NC13702.
About five 1937 S-1-B Airster were built with ATC 705, including NC15536 and NC18135, priced at $2,995. The prototype, NX/NC18967, was built as a class project at the Warren School of Aviation in Los Angeles

Designed and built by H.A. Searsby of Nottingham, UK, the Special was a single-seat, wooden, primary glider. It featured wing-warping, and one of the A-frame members was placed in front of the pilot.
Only one was built, which had its first flight on 7 September 1930 at Wirksworth, Derbyshire, UK.
Built by Roy B Scroggs in 1930, The Last Laugh was similar to a dartlike paper airplane, with a narrow delta-wing with about a 75-degree sweepback/ Powered by a 90hp Curtiss OX-5, it had elevons and twin rudders. Registered N10648, the pilot sat in a closed cabin under the “wing”.
Scroggs prophesized that his airplane would one day revolutionize the entire air industry. The creation was test-flown successfully at an altitude of 10′, and Scroggs predicted an eventual top speed of 300mph, but he, and his airplane, eventually faded away.

Scroggs was a tailor and built ‘The Last Laugh’ airplane in 1930.
The Scott Two-seater tandem sailplane was built by W.R. Scott in 1932, in the UK. First flown in 1933, it was written off in November 1933.
