WO-29 Sport 1929 = 2pOB; 110hp Warner Scarab; span: 30'1" length: 21'6" load: 590# v: 113/90/30 range: 475. Design based on Waterhouse Roamair (and often mistaken for it), but partly credited to Earl Ovington, hence the "WO" designation. POP: 3 (one magazine article mentions 5 being completed); , aka Armton WO-29 c/n 1, [NX796K] with 125hp Warner, and [X12242] in 1931, also seen as Armtron WO-29.

Sparrowhawk 1929 = 3pOB; 100hp Cameron; span: 29'0" length: 18'9" load: 730# v: 125/100/35. $2,950. AZ Corporation Commission replied 11/14/00 to query from Jarratt: "Could find no records for a corporation by this name."

Sceptre II 1985 = Generally identical to Sceptre I but 2p with 85hp Limbach.
Aquaplane 1930 = 1pOhwMF; 32hp (Evinrude?); span: 32'0". While technically not an aircraft, this was an interesting concept of an outboard motor attached to a sled-like hull, which in turn was attached by pivoting booms to a very basic seaplane-like structure. The motor pushed the arrangement along and, at about 30mph, the forward part would rise and fly at an altitude of about 10', laterally controlled by its rudder, vertically by its elevator. POP: 2.

Special A-1 (or 1-A) 1929 = 2pOB with "special curve-wing design;" 150hp Hisso; span: 28'0" length: 28'0". S D Robinson. [X3442]. According to CAA correspondence, Robinson became ill and never finished the plane. In May 1930, he was reported as deceased and it went to executor Pearl Robinson, who applied for the ID number, stating that the plane was "still in process of manufacture." With no further reports and the aircraft assumably unbuilt, CAA cancelled the license 2/10/33.
Sailaire 1929 = 2pOB; 90hp Curtiss OX-5; no specs found.POP: 1 [468E] c/n JT-1. Reported as sold at Salt Lake City UT in 1920, again at Elko NV in 1935. Research by John Jarratt brings to light a s/n 4446 for the OX-5, which is the same as that of the Robinson-Christensen-Wright listed below, so this ship msut have been a solo project by Robinson, either precursor or follow-on to that trio's Firefly.
Banger Bill 1948 = 1pOlwM; 85hp Continental C-85. Midget racer Suzy Jayne (p: W F Robinson, Lou Russo) [NX83Y], rebuilt from 1933 Brown B-1. Co-sponsored by Ralph Bushey and C F McGrew.

Fred H Rohr was the person who designed and built the fuel tanks for Lindbergh's NYP Ryan. SEE ALSO "If He Had Only Known" in The Lighter Side.
In 1974, Rohr Chairman Burt Raynes resolved to move Rohr into the light airplane market offering an undeniably superior product by summoning Walt Mooney as designer and project manager to come up with a quantum leap in light aircraft technology. It would have better performance, greater safety, accessibility and comfort, greater economy, and lower production cost than any competitor. Mooney selected the best people Rohr had, including key players Bill Chana, Bob Fronius, Mike Voydisch, and Don Westergren, and built three airframestwo flying prototypes and a static testerplus 1/10- and 1/2-scale models for feasibility tests. By the time the project ended (for reasons having nothing to do with the merits of the airplane), one prototype had accumulated 23 hours in the air. ( F Marc de Piolenc)

1914 = 1pOmM; Curtiss OXX and twin tractor props. Tubelike fuselage, with lateral balancing by automtic stabilizers in the wingtips, compensating shutters that were open and closed by a pendulum mounted at the plane's c/g. An engine-driven pump supplied compressed air through tubes to the shutters when activated by the pendulum. Its test flight in Apr 1914 ended in disaster when the pendulum took its job too seriously at 50' and overcontrolled the plane into the ground, damaging it beyond economical repair.

Often identified as TM-1, its basic frame was used in a rebuild of the that plane.
