Built in 1928 in Hollywood, California, by Newbauer Vertical Airplane Co, the Hummingbird was an ornithopter-type craft with two revolving disks on top, and wings made from lateral vanes, all powered by a four-cylinder motorcycle engine.
The Hummingbird weighed 3496 lb and carried 44 Imp.Gal of fuel.
There is no record found of flight and US patent #1,743,327 was issued in 1930.

In 1927 Valentine Newbauer built a single-place open helicopter with two propeller-type (coaxial?) rotors and a tractor prop. A model was built, powered by a 1.5hp engine. Newbauer claimed it lifted 60 pounds, which is judged by experts to be highly improbable.
He was engaged in helicopter experiments from 1917-27 and held several patents. One project was entered in the 1924 British helicopter competition.
Built in 1922 by Eric Nessler in France, it arrived at Camp Mouillard on August 5, 1922. By August 15, the machine is ready and performs a few small flights on the plain with a maximum duration of 8 seconds. On August 17, it fell on the front, breaking the landing gear, seat and tail. It flew again on August 24 with a flight of 17 seconds over the Toupe plateau but was slightly damaged on landing.
On August 27, departing from the summit of Combegrasse, towards Aydat, in no wind, some jumps on the slope were made before final takeoff but a flight of 1 min 3 sec was made. During this flight, the aircraft succeeded in gaining height.

Initial experiments by Nemeth with rotating wingforms go back to 1929. In 1934 Nemeth designed, and students at Miami University (OH) built the Umbrellaplane / Roundwing.
A two place monoplane featuring a circular wing on a lengthened Alliance Argo fuselage for STOL performance, to test circular wing configuration.
The sole example, NX13651, was powered by a 90hp Lambert, later repowered with a 120hp Warner Scarab, and later reworked as a divided wing. Name has been seen spelled Nuneth.

In 1932 two two-place monoplane Nelson Trainer were built by Norman Nelson.
Two known examples were built; N12925 c/n R-2 with a 65hp Velie engine and N12958 c/n R-3 with a 90hp Lambert engine.

The registration was issued on 26 April 1929, reissued on 17 March 1930, reported in storage Feb 1933, and cancelled 3/15/36.

Designed by Richard Korman, the three-place cabin Neilsen Steel Aircraft Co NC-1 Golden Bear, or Coach, was a fabric-covered Ryan B-3 type. Subsequent models were planned to be metal-clad.
Priced at $7,500 in 1928, it was destroyed by an angry crowd at a “thrill show” at Oakland Speedway in Aug 1939 after its performance failed to meet their expectations.
A second one, with 300hp Wright J-6, was reportedly under construction at the time, but its history is unknown.
