This aircraft was designed and built by Mike Huffman during the late 1960s and early 1970s. It featured a welded steel-tube fuselage, aluminum wings and tail boom, and composite tail surfaces. Powered by a McCulloch 72-hp target drone engine, it was essentially an ultralight before the ultralight movement began.
Flugzeugbau Dr. Georg Huffer produced a civilian version of the First World War Fokker D.VII fighter, known as the Huffer H.9. It was an open-cockpit training/sporting two-seater powered by a Mercedes engine.
The twin Packard XHB-3, ordered from Huff Daland in 1926, was cancelled before it had been built.
The Huff Daland XHB 1 of 1926 27 was an enlarged LB 1, with a single 800 hp Packard 2A 2540, but never progressed beyond prototype stage.
Keystone Aircraft Corpora¬tion built a total of 220 aircraft in the US Army Air Corps LB (light bombardment) category, venturing briefly also into the B (bombardment) and HB (heavy bombardment) classifications. All except ten of the LBs were twin engined aircraft, but had their origins in the single–engined XLB 1 prototype and nine pre series LB 1 biplanes produced in 1925 by Key¬stone’s predecessor company, Huff Daland and Co Inc of Ogdensburg, New York, which became Keystone in March 1927.
The XLB-1 three-seat, single-engine light bomber was tested in 1923, mount¬ing an 800 hp Packard and was developed as the twin-engined XLB-3, with a crew of five. The basic LB 1 airframe was redesigned by Keystone in 1927 as the twin engined XLB¬3A.
John W Hudson built a 100hp@1000rpm to 120hp@1200rpm 10-cylinder air-cooled radial aero engine of 693.8ci, with a dry weight 32 lb#.
Devised and made by Mr Sandy Hudson Jr, a law enforcement operator of Black Mountain, North Carolina, the Tri-Motor is a powered conversion of a Schweizer SGU 1-19 single-seat sailplane fitted with three West Bend go-kart engines producing a total of 17.3hp and each driving a 2ft 1 in diameter two-blade wooden pusher propeller. Two West Bend Model 70013 engines are mounted on pylons on each side of the fuselage aft of the cockpit and between the wing bracing struts, and a West Bend Model 70012 is carried on a pylon on top of the rear fuselage in front of the fin. The total fuel capacity is approximately 2 US gallons, a small separate tank for the rear engine being mounted on the fin leading edge.
This powered conversion of SGU 1-19 N91817 was started in May 1962 and completed in September 1963 at a cost of $1,000; Mr Hudson won an award for the lowest powered aircraft with the Tri-Motor at the 1963 Fly-In of the Experimental Aircraft Assocation.
The standard SGU 1-19 is a utility and training single-seater of early postwar design with an all wood constant chord fabric-covered wooden wing with two spruce spars, spruce and mahogany plywood ribs and a ply leading edge. The fuselage is a fabric-covered welded chrome-molybdenum steel tube structure, and the landing gear is an unsprung monowheel with a single skid mounted on rubber blocks ahead of it, and a rubber-mounted tailskid. The tailplane and elevators are fabric-covered welded steel tube surfaces, the tailplane being braced, and the fin and rudder are either of fabric covered wooden construction when the SGU 1-19 is supplied in kit form for amateur builders, or of fabric covered steel and aluminium alloy when factory built. The pilot could sit in an open cockpit, or a transparent canopy could be provided as an optional ‘extra’.

The Hübner Eindecker of 1912, tentatively identified as his second monoplane (E II), powered by a 50 hp Argus.
At the end of of 1935 Hübner flew the Mücke for the first time. Flight areas were the Neckarwiesen and Obrigheim, Germany. The biplane is detachable and can fit a trailer. The 2 cyliner, pusher, 1.8Ps engine was fastened between two struts.
The Hubertec Thermik (English: Thermal) is a German ultralight trike, designed and produced by Hubertec of Aach, Rhineland-Palatinate. The aircraft was supplied as a complete ready-to-fly-aircraft.
The company is an industrial prototyping and exercise machine specialist that decided to produce an ultralight trike design as a sideline project.
