REVISED: 10/12/08


1929: Armton Aircraft Syndicate (fdrs: L C Armstrong, Earl Ovington), 1635 El Centro Ave, Hollywood CA. 1929: RoamAIRcraft Corp.

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); [595], aka Armton WO-29 c/n 1, [NX796K] with 125hp Warner, and [X12242] in 1931, also seen as Armtron WO-29.


Samuel B Robbins, Boise City OK.

Silver Wing c.1925 = 2pOM; 90hp Curtiss OX-5; span: 33'0" length: 28'0". Most likely a monoplane rebuild of a Curtiss JN-4 or Standard J-1. [894H] c/n 1sub.


Reggie Robbins, Dallas TX.

  Robbins Special [NR11987] (Jack Robbins coll via David Llorente)

Racer, Special 1932 = 1pOlwM; 180hp Hisso E. Racer constructed around the undercarriage and wings of a Wedell-Williams 44 [NR278V] with, reportedly, the fuselage of an earlier W-W (or a Waco, again reportedly). Lack of race appearances saw it in use more as a private plane for barnstorming [NR11987] c/n 11. Repowered 1934 with 320hp Wright as Robbins Special; later sold to Jess Bristow.


Roberts Aircraft Corp, Phoenix AZ.

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."


Don Roberts, Noblesville IN.

Chinese Bandit 1971 = 1pOlwM; Continental A-65. All-wood, it took three years to build at a cost of $1500.


Roberts Sport Aircraft, Yakima WA.

Sceptre I 1983 = 1pClwM; 52hp Rotax 503 pusher; span: 26'5" length: 19'5" load: 375# v: 115/x/45; ff: 11/x/83. Twin booms; [N92RA].

Sceptre II 1985 = Generally identical to Sceptre I but 2p with 85hp Limbach.


Milton & Russell Robertson, Alameda CA.

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.


Robertson Aircraft Corp, Lambert Field, St Louis MO.

RO-154 Rovair 1945 = 4p unknown type. No found connection with Curtiss-Robertson or Curtiss-Wright.


(James L) Robertson Development Co, Fort Worth TX.

  Robertson Skylark SRX-1 [N2903B] (1955 EAA Experimenter)

Skylark SRX-1 1955 = STOL. 5pChwM; 260hp Continental GO-260-2X; span: 40'0" length: 30'6" load: 125# v: 165/150/25. Spoiler-type full-span shrouds to prevent stalling, full-span flaps, "spoilerons" atop the wings, flying tail, and other mixed technologies permitted landings and take-offs in less than 120'. POP: 1 [N2903B].


1973: (James L) Robertson Aircraft Corp, Renton WA. 1975: Robertson/Standard Inc, propeller development.

1973 - STOL conversions of various Cessna and Piper aircraft. Typical examples:
    Cessna 182 Skylane = load: 1351# v: 183/172/39 range: 1,210 ceiling: 17,850'; take-off run: 430' landing run: 325'.
    Cessna 337 Skymaster = load: 1992# v: 204/194/45 range: 1,390 ceiling: 20,100'; take-off run: 428' landing run: 343'.
    Piper PA-28-235 Cherokee = load: 1430# v: 161/152/45 range: 1,066 ceiling: 12,000'; take-off run: 550' landing run: 490'.
    Piper PA-23-235 Aztec = load: 2065# v: 227/220/47 range: 1,280 ceiling: 18,100'; take-off run: 690' landing run: 640'.

  Robin Hood (Aerial Age via Joe Martin)

c.1916 = Nothing found but a photo of its stall at a 1917 Aero Exposition, which featured what appears to be a mid-wing display model.


Hugh Robinson, Joplin and St Louis MO.

  Robinson 1908 (Aero Digest)

1908 = 1pOmwM; 30hp. Open triangular fuselage with Blériot-style wings. Used for exhibitions.

  Robinson 1915 (Aero Digest)

1915 = 1pOB; v: 81. Gross wt: 600#.


Arthur J Robinson, Sheridan WY.

1909 = 1pOM; 20hp Curtiss; span: 32'9" length: 39'3".


William C "Billy" Robinson, Grinnell IA.

1913 = 1pOhwM; 60hp Robinson. Exhibition aircraft; set an endurance and distance record in 1914 of 4h:44m for 390mi, and was contracted as the government's second air mail carrier.

1915 = 1pOB; 100hp Robertson. Crashed on 3/11/16, ending a brief but notable career.


Miami Aircraft Co (fdr: S D Robinson), RFD 2, Miami OK.

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.


James Robinson, no location.

Sailair c.1930 = 3pOB; 90hp Curtiss OX-5. [468E].


William F "Billie" Robinson, Burbank CA.

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.

  Robinson MDR-1 (EAA Experimenter via Craig Westerman)

MDR-1 Special c.1950 = Racer. 1pOlwM; 85hp Continental C-85. Also had a 115hp Lycoming. Described as "an extremely small airplane" and "designed for aerobatics." Cut-down Luscombe wing panels.


Cleo Robinson, Phillipsburg KS.

Mere Merit 1964 = 2pOB; 145hp Warner; span: 28'0" length: 20'0" load: 500# v: x/120/43 range: 400. A four-fifths replica of Rearwin's Ken-Royce biplane of 1929. [N68270]. The plane was restored in the 1990s and fitted with a 125hp Warner, possibly re-registered [NX400KR].


(Frank) Robinson Helicopter Corp, Torrance CA.

  Robinson R-22 [N80142] (Eddie Coates coll)

R22 1975 = 2pCH; 180hp Lycoming O-360-J2A; rotor: 25'2" length: 28'10" load: 531# v: 117/110/0 range: 207 ceiling: 14,000'; ff: 8/28/75. $139,000 (1997); POP: 2,750.

R44 1990 = 4pCH; 260hp Lycoming O-540-F1B5; rotor: 33'0" length: 38'4" load: 980# v: 138/132/0 ceiling: 14,000'; ff: 3/31/90. $265,000 (1997); POP: 390.


No data, Los Angeles CA.

Firefly c.1930 = 3pOB; 90hp Curtiss OX-5. [504] c/n CRW-1. Home-built reportedly not completed to flying status.


1925: (Jean A) Roché-(John Quintin) Dohse, 28 Watts St, Dayton OH. 1928: Reorganized as Aeronca Corp.

  Roché-Dohse Flying Flivver

Flying Flivver 1925 = 1pOhwM; 29hp Morehouse. Jean Roché, who received a patent in 1914 for a design of an aircraft incorporating "automatic stability," which was most likely the basis for this airplane [3774]. Forerunner of Aeronca C was first taxied with a four-cylinder Henderson motorcycle engine, finally flew with the first Morehouse engine on 9/1/25, with Roché at the controls, who was not a pilot, but he unintentionally became airborne during taxi tests and circled for about 10 minutes before making a perfect landing—the only time since the 1903 Wright brothers flight that a plane, pilot, and powerplant shared their first flight! The prototype went on to make some 200 later flights. A 26hp Aeronca E-107 engine (Roy Poole & Robert Galloway) was substituted for production Aeronca aircraft.


(Charles & Harry) Rocheville Aircraft Corp Ltd/Rocheville Ltd, 3510 Percy St, Los Angeles CA.

1923 = 1pOhwM. Attractive variable-camber design with a Fokker D.7 top wing by then-Machinist Mate 1c Rocheville while stationed at San Diego.

193? = Type unknown. Appears in registers as "Rochivell" [5922] with a Hisso engine. Consensus is that it's Charlie Rocheville and his Rocheville Special.

A 1931 = 2pOM; Axelson. One source states that this was the aircraft specially built for tests with the Deeble Double-Action motor. [12270]. Claimed to be a rebuilt Emsco B-4, previously registered as [X846N].

  Rocheville Arctic Tern Long Beach 1933 [NR221Y] (Elwood W Mason)
  Rocheville Arctic Tern 1/72 model (Claudio Luchina)

Arctic Tern aka EMSCO Arctic Tern 1932 = 3pO/CmwMF; 300hp Wasp Junior (or 420hp Wasp). Charles Rocheville. Wing from a Lockheed Sirius, tail from a Lockheed Vega. Special-purpose plane for Shell Oil Co in Alaskan photographic explorations. Pilot in open cockpit in small nacelle, crew in enclosed pods atop pontoons. Crashed in June 1933 during testing [NR221Y].

Flying Wing SEE Emsco B-8.

R-2 1930 = 1pOM with 90hp Cirrus, very likely another variable-camber project. [X173W] c/n 2.

VC-2 aka VCM-1 1930 = 5pOmwM; 220hp Wright J-5; span: 46'0" length: 30'6". Experimental, variable-camber, Clark-Y wing design with 144sqft expanding wing area and 120sqft of variable trailing edge. POP: 1 [7922] c/n VCM-1, also appears with 150hp Hisso E-2, was possibly modified from Emsco B-4 [X137N].

Monarch 26 1961 = ChwM rg; load: 13,000# v: x/305/x range: 2000. Extensively modified executive conversion of Douglas A-26. POP: 4 to 6.


Location unknown.

c.1927 = 4pChwM; 150hp Hisso A. [3299].



B F Roehrig, San Diego CA.

1910 = 1pOB; 60-90hp Elbridge pusher; span: 45'0" length: 47'0". Awarded the Knabenshue Cup at the 1910 Aero Club Meet for flying "many times the required distance."


Casten A Roepkin, Dayton OH.

1928 = 2pChwM; 80hp LeRhône rotary. Constructed at Rinehart-Whelan field, Howard Rinehart cautioned the builder that it was a crudely-built and potentially dangerous plane. Two weeks after it was finished, it ran into the smokestack of the Frigidaire factory at Moraine OH on 10/14/28, killing Roepkin and a friend. [4493].


Hyattsville MD.

c.1910 = OM with circular tube fuselage. No other data found.


(John W) Rogers Aircraft Corp, Los Angeles CA.

A-1 1921 = 2pOhwM; 65hp Velie M-5. One of several custom-built planes or modifications, most of them based on surplus Standard J-1s, by Rogers at his Western Ave airports in Los Angeles 1921-23 [15513] (1938 registry). SEE ALSO Airline Arrow.

C-1 SEE Pacific-Standard (Venice CA).

  Rogers Monoplane (Museum of Flight)

Monoplane c.1922 = 1pOhwM; 150hp Curtiss C-6; no specs found. This one suggests a redesign of a surplus Fokker D.7 (our guess), likely built for competition, as witness the race number on its wing.


c.1925 (Harry) Rogers Air Lines, Garden City NY & Miami FL. 1928: Rogers Aeronautical Mfg Co, Roosevelt Field, Long Island NY.

  Rogers RBX [NC9735] (1931 Aircraft Yearbook)

Oscar A Rohner, Aurora CO.

Aurora 1929 = OM; Lawrance A-3, Szekely in construction late 1930 [97N] c/n 11. Reported to CAA as "building stopped 2/13/30," likely never finished. Reg cancelled 2/23/34 as dismantled.


(Fred H) Rohr Aircraft Corp, Chula Vista CA. 1940: Rohr Corp. 19??: Goodrich Aerostructures Group, contract mfr of engine cowlings and pylons

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 airframes—two flying prototypes and a static tester—plus 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)

  Rohr 2-175 [N62R]
  Rohr 2-175 3-view (TWITT)

2-175 1974 = 2p personal delta; 150hp Lycoming special high-rpm (4400rpm) and four-blade ducted-fan pusher prop plus a six-blade stator; span: 30'0" length: 28'0". Walt Mooney. Gross wt: 1450#. Fiberglass-reinforced plastic honeycomb construction. Sparless folding wings and vertical tail for storage in an average one-car garage. POP: 3; 2 flying prototypes [Nx, N62R] and 1 for static testing. A shortage of funds precluded further development.

  Rohr MR-1 [NX50651] (Dan Shumaker coll)

Guppie or Guppy 1946 = Perhaps a reconfiguration of MR-1 to more conventional lines (if its tadpole shape could be called conventional), which this is contested by those who feel it is the other way around, that the tail-first came first. Whichever, the shapes were similar, with a visual distinction in the canard version and, as the photo shows, it flew. [NX50651].

MR-1 (?>MO-1) 1946 = 2pCmwM rg?; 85hp Continental C-85; v: x/135/x. B F Haynes (?>Raines), Frank McGreery. Bulbous-bodied canard layout with V-tail, tricycle gear, wing with slots. Originally tried with 36hp Aeronca E-113, then 65hp C-65.

PB2Y-3R 1945 = 44p conversion for Naval Air Transport Service of Consolidated PB2Y-3 with turrets removed, side hatch added. POP: 10.


Yves Rolland, Cicero IL.

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.

(Jack W) Rose Aeroplane & Motor Co, 3521 Armitage Ave, Chicago IL. 1948: (Foster) Hannaford Aircraft Co Inc, Mundelein IL (license for kit components only). c.1965: Rights acquired by Douglas Rhinehart, Farmington NM.

  Rose A-1 Parrakeet (David Duffy coll)

A-1 Parrakeet or Parakeet 1931 (ATC 2-514) = 1pOB; 40hp Continental A-40; span: 20'0" length: 16'4" load: 262# v: 100/85/35 range: 340. Production began in 1936. Various engines were tried on A-1, but were never certified in the standard category. Prototype, [NX13677] c/n 101, first had a Henderson engine that proved unreliable and too heavy for its horsepower. [NX14842] was tried with 50hp Menasco in 1934. $1,475, $975 less motor; POP: 8 (includes the following three entries), plus an unknown number of later Hannaford B $85 kit-planes which showed up with countless modifications.

Hannaford was licensed to manufacture the Rose Parrakeet. Rose drawings were copied and (it) became the Hannaford B, with marketed plans. In that Rose Parrakeet had a Type 2 certification, aircraft completed had to be inspected by the CAA, and there are no records of a certified Hannaford Parrakeet. There is evidence suggesting Hannaford built two aircraft. Advertising by Hannaford indicates that the Hannaford Parrakeet and subsequent Hannaford B are in fact Rose Parrakeets. (— Don Pellegreno 7/6/04)

  Rose A-2F Parrakeet [NC18252] (Frank Rezich coll)

A-2F 1938 = 50hp Franklin; load: 264# v: 105/90/37. [NX/NC18252].

A-2P 1938 = 50hp Poyer.
A-3F 1938 = As A-1, but with 60hp Franklin.

A-4, -4C 1949 = 65hp Continental A-65; load: 270# v: 115/100/40. $2,775; later Continental C-85 (v: 120/120/40) for $2,885, POP: 4. Design revived as aerobatic Rhinehart-Rose A-4C Parakeet in 1973 with Continental O-200; $10,500, POP: 5.

Doug Rhinehart obtained STC SA458SW for the use of a Continental C-65 on c/n 107. He also obtained three other STCs: SA787SW for a C-85 on c/n 105, SA1040SW for a Continental O-200 on c/n 505, and SA1040SW(rev) for an O-200 on newly constructed Rhinehart-Rose Parrakeet A4-C. Jack Rose licensed Rhinehart-Rose Mfg (Aztec NM) to build five Rhinehart-Rose Parrakeets under TC 2-514 and STC SA1040SW(rev). (— Don Pellegreno 7/6/04)


Cort A Rosenhan, Midvale UT.

Model A 1937 = 2pOM; 50hp Tank. [13395] c/n 1. Sold to Granite School District, Salt Lake City, 9/29/43 as [N13395]; reg cancelled 9/19/49.

c.1906 = Undescribed entrant in 'Flying Machine' events at Intl Aeronautic Tournament, St Louis MO, 21-24 Oct 1907.

  Roshon (1913 Jane's)

1908 = This multi-multi-wing oddity had two banks of seven planes, plus two more of lesser span on top of those, all fitted with about 20 longitudinal parafoils, and all perched precariously on a four-wheel carriage—the only thing missing was curtains. Fabric-covered wood and metal tube frame. It never flew, which comes as no surprise, but it is an interesting example of the extremes to which aerial experiments were carried.


(Orrin E) Ross Aircraft Co, Amityville NY.

  Ross RS-2L

Parasol RS-1, -2L 1938/1947 (ATC 732) = 2pOhwM; 40hp Continental A-40; span: 30'0" length: 20'0" load: 422# v: 83/75/38 range: 225. A very basic airplane for a very basic $875, available with 50hp A-50 for $940. POP: 1 [NX1316]. Modified in 1946 as RS-2L with 65hp Lycoming O-145 (load: 440# v: 103/90/38) and cockpit canopies for $1800, it was another postwar effort that failed to get into production.


Oliver Andre Rosto (Ole Augustinussen Røstø), Duluth MN.

  Rosto (via Al Grady)

Duluth 1 1909 (?>1913) = Home-built by Norwegian émigré Rosto. 30hp 3-cyl Anzani-powered monoplane, patterned after the smaller Blériot; span: 30'0" length: 35'0" v: 50 (?>40); ff (from frozen bay on skis): 11/5/09 or 11/15/09. Claim from a newspaper report of the ship reaching 100' altitude was likely exaggerated or miscalculated.


Roteron Inc, CA.

X-100 c.1946 = 1pCH; 25hp 5-cyl Noble; rotor: 15'3" v: 110. Gross wt: 240#. An attractive, minuscule, all-metal "Hoppi-copter" coaxial design was presented in a publicity photo as available for "$2,800 in limited production." Apparently very limited.

"Few people who know of the work of Langley, Lilienthal, Pilcher, Maxim, and Chanute, but will be inclined to believe that long before the year 2000 A.D., and very probably before 1950, a successful aeroplane will have soared and come home safe and sound." — Wilbur Wright, 1909
