  Ochoa (1909 Fly)

Jersey Devil aka Jersey Mosquito 1908 = 1pOhwM; 12hp water-cooled motor; span: 18'0" length: 7'0". This early creation had two "very large steel flapping wings" covered with fabric, an innovative aft rudder, a six-bladed prop, and appeared in a show at Arlington in May 1909, "but did not fly." One problem might have been with its "collapsible" wing framework, with which the inventor explained in July 1909 Fly, "By reversing the engine, one can back up the monoplane ... into a barn, where it does not occupy as much room as an automobile."

PB's (2-295) also approved installation of 100hp Cirrus on PCs. Prototype [X187N] had 100hp Kinner, replaced by 90hp Cirrus MkIII before flight testing.

1977 = Home-built. 1pOB; 85hp Continental C-85; span: 28'0" length: 18'0" load: 230# v: 95/80/45 range: 350. All-metal fuselage; wood-framed, fabric-covered wings and tail; conventional gear with panted wheels.

  Airmaster Coupe Art from company brochure (Tom Heitzman coll)

Airmaster Coupe 1928 = 3pChwM; 90hp LeBlond 5F; span: 32'9" length: 21'0" load: 500# v: 135/94/42 range: 350. Joseph W Esch. Described as styled after d's Ryan NYP, it actually looked more like an early Monocoupe. $3,000; POP: 1 [568K] c/n AY-5, built by students at subsidiary Ohio Aero School.

Youngster 1928 = 2p Airmaster with 60hp LeBlond 5D; length: 19'9" load: 200#. Side-by-side seating. First tried with 60hp Anzani. $2,375; POP: 2, [7200] c/n A-3 and [X7872] c/n AY4-4, also first as a student project, but advertised in aviation magazines of 1928.

195? = 1pChwM agricultural plane; 115hp; span: 29'0" length: 22'1" load: 624#. Reworked Piper J-3 fuselage and wing with tip plates. The pilot sat in a raised cockpit on top of the wing with a fine view of the countryside.

  Ohm & Stoppelbein Special [N6H] (K O Eckland coll)

Special 1950 = 1pCmwM; 85hp Continental C-85; span: 18'6" length: 16'3"; ff: 8/x/50. Midget racer [N6H].

SK-1 1929 = 3pOlwM; 100hp Kinner K-5; span: 26'0" v: 100. Leland Atwood. POP: 1 [X8862]. Backed by a group of investors, the sport trainer performed well in test flights (p: Fred Herman) but production, as well as development of a 10p transport, was cancelled by financial woes in the Depression.

Baby Lakes 1954 = 1pOB; 80hp Continental A-80; span: 16'8" length: 13'9" load: 375# v: 135/118/50. 5/8-scale replica of Great Lakes Sport Trainer. Andrew Oldfield. 650 sets of drawings sold and 40 were known to be built by 1982. Later versions were Super Baby Lakes with a 115hp Avco-Lycoming O-235 and 2p Buddy Baby Lakes.

1921 = 1pOB; 80hp Gnôme rotary. A mish-mash of surplus JN-4, Thomas-Morse, and Standard components produced a creation looking not too unlike something the Sopwith factory might have dreamed up. Used by Oleson in exhibition flights around Iowa until magnesium flares, used in night-time shows, ignited as he landed—he barely managed to get out before his ship caught fire. Although the fabric went up in flames, the frame was only scorched and it was rebuilt in 1922.

OM-1 Connecticut Yankee 1929 = 2pOlwM; 40hp Anzani SR-3. All-metal; dual control. Also found as having had 60hp Anzani, 90hp Brownback C-400, and 70hp Siemens installed along the way. [492H] c/n 1. Records show it as "abandoned" 11/25/32 and "permanently dismantled" 12/22/32, but sold "less engine" 3/23/35 and a 60hp Anzani installed, then resold 7/22/37. License cancelled 6/3/38. Connection between this and the previous Oleson is unknown. (Thanks to John M Jarratt for chasing down this elusive bird.)

  Olson Ambassador [N1600J] (Aviation Week via Ron Dupas)

Ambassador 1965 = 3-4pClwM; 100hp Continental O-200A; load: 779# v: 142/131/x. Fiberglass-covered, licensed manufacture of French Jodel DR.1050. $9,000 (projected, including avionics); POP: unk.

  Omega BS-12 [N285B] (Aviation Week via Ron Dupas)

BS-12 1956 = 2pCH; two 210hp Franklin 6AS; rotor: 39'0" (?>36'0") length: 39'1" load: 1400# v: 95/60/0 range: 175 ceiling: 11,500'; ff: 10/29/56 (?>12/26/56). The basic BS-12 was suitable for both cargo and passenger operations in a standard airline pod. Controllability and stability of the aircraft was maintained with the cargo pod directly behind the cabin in the external bay within the aircraft's c/g envelope. Besides eliminating in-flight drag, that allowed the Omega to use the ground cushion effect during take-off and landing. The "flying crane" configuration, which Sznycer pioneered, was also suitable for carrying unwieldy cargo such as pipes, lumber, or other objects in its open cargo bay. In emergency situations, all loads (except the passenger pod) could be jettisoned by explosive bolts. Complete failure of one engine in flight reportedly required no extra piloting technique as operational rpm would be adjusted for by the good engine. $77,500; POP: 1 prototype [N267B] c/n 156.

BS-12D-3 1960 = the second D-1 refitted with a supercharged FrankIin 6AS-335 BS-12F - Projected, not known if built. Two Allison T63 or Boeing 502-W turbines.

BS-12J - Projected, not known if built. Two 290hp Lycoming IO-540; load: 1695#; improved performance at high altitudes and improved single-engine performance.

BS-17A Airliner - Projected, not known if built. Three Allison or Boeing turbines and 5-blade rotor. Expanded passenger pod.

Aristocraft II 1963 = 4pChwM; 200hp Lycoming IO-360. Built from parts of the original Waco Aristocraft including the wings, struts, and horizontal tail. Twin fins were retained, but the engine was moved to the nose. Taildragger configuration. POP: 1 [N34219].

Model W 1968 = 6pChwM; 200hp Lycoming IO-360; span: 37'6" length: 26'0" v: 127/109/47 range: 870. A rebuild of Aristocraft II with a single fin and tricycle gear. POP: 1 [N34219]. A more powerful version with a 350hp Page radial engine was planned.

Pea Pod 1963 = 1pCmwM canard; 35hp Kiekhaefer O-4-35 mounted inside the vertical fin; span: 8'0" length: 9'0" load: 220# v (est): 132/115/55 range (est): 350. This odd ship might best be described as a flying barn door with its angular wing of 1.6 aspect ratio. The pilot had a prone position, with most of his body inside the wing. The plane could be carried atop the family auto. Taxi tests were performed, but it reportedly never flew. POP: 1 [N10T].

  Orenco F-4 (Frank Tallman coll)
  Orenco Tourister Original configuration and owner Earl Daugherty
  Orenco Tourister Mantz mod for film work, fake tail number (K O Eckland)

F-4 Tourister 1920 = 4pOB; 150hp Wright-Hisso A; span: 38'0" length: 24'10" load: 955# v: 100/x/43 range: 290 (data for Hisso). Two side-by-side cockpits. Also noted with 180hp Hisso E.

Its nameplate shows [the Daugherty plane] as c/n 45; however, it is doubtful Orenco made that many. This plane was bought by Daughtery and operated at his field in Long Beach CA—he even got married in the air in it! Later sold to Paul Mantz, who modified it for film work, such as a Vought VE-7 in "Task Force" (1949) and others. It's now (2002) owned by Kermit Weeks. (— Gil Halpin 9/4/02)

H-3 Commercial 1920 = OB; two 300hp Wright-Hisso H; span: (upper) 56'0" (lower) 42'0" length: 36'0" load: 2470# v: 140/x/48 range: 422. Design adaption of H-2, but there is no record of its use.

1908 = 1pOB; 8hp Belgian-make motor chain-driving two propellers with "variable pitch;" span: 18'0". Gross wt: 100#, "not including driver." Horsepower is suspect, but is as shown in Jane's. Vertical rudder aft could "be converted into a flat plane at will;" horizontal rudder in front also acted as a brake (was that really necessary for 8hp?). Over the top wing was a "mushroom-shaped plane on springs, capable of any distortion, intended to act as a bird's tail does," which Orme claimed would "prevent the sudden plunging of the aerial craft to earth if any mishap occurs." Despite that feature, it plunged to earth on 12/25/08 when a loose wire broke the prop, but news report stated it would be repaired and "the tests resumed." No further word was found.

Sport 1928 = 2pOhwM; 65hp Velie. POP: 1 [465] c/n 7735sub; sold to Dearborn Aero Club in 1933. Could be Pietenpol Air Camper?

Special c.1967 = 2pClwM; two 200hp Rangers; span: 38'0" length: 26'0" v: x/150/x. [N7755C].

Gyroplane 1912 = Conceptual flying machine described on a stock certificate as a combination of the helicopter principle and an "ordinary monoplane," constructed of steel and aluminum, thus "avoiding the danger of burning up."
