Circa 1909, F. Raiche and C. M. Crout designed and built a biplane in the USA.

An invention of William Rahn in collaboration with Gus Miller, formerly with the Zeppelin Works in Germany, this 1933 experimental aircraft was only 15 feet long, and carried two 6-foot span rotating wings on each side. Powered with a 240 hp supercharged Wright Whirlwind motor, the wings are disposed about a central axis and change their incidence so as to produce both lift and negative drag.
It was said to fly forwards at up to 100 mph without the aid of a normal propeller.

The two 6′ rotating wings on each side theoretically would cause the plane to rise or descend vertically, or fly laterally without a conventional propeller up to 100mph, but it is unrecorded if this 15′-long creation, registered NX13247, ever accomplished any of these feats.

Qualifies as an LSA. The “Special II” can be built as a legal ultralight trainer or with a larger engine, as an experimental. The “Special II” basic kit will be an all-wood kit, like the single seat, to keep the pricing affordable. These kits are fairly fast to build. The kit was planned to be available in a steel tube version.
