Ultralight trike powered hang glider with a Rogallo wing and a three-wheeled undercarriage

An ultralight trike is a type of powered hang glider where flight control is by weight-shift. These aircraft have a fabric flex-wing from which is suspended a tricycle fuselage pod driven by a pusher propeller. The pod accommodates either a solo pilot, or a pilot and a single passenger. Trikes grant affordable, accessible, and exciting flying, and have been popular since the 1980s.

Tandem arrangement in which people, machines, or animals are in line behind one another facing forward

Tandem, or in tandem, is an arrangement in which a team of machines, animals or people are lined up one behind another, all facing in the same direction.

Tricycle landing gear aircraft undercarriage arranged with main gear under the wing or fuselage and a third set under the nose

Tricycle gear is a type of aircraft undercarriage, or landing gear, arranged in a tricycle fashion. The tricycle arrangement has a single nose wheel in the front, and two or more main wheels slightly aft of the center of gravity. Tricycle gear aircraft are the easiest to take-off, land and taxi, and consequently the configuration is the most widely used on aircraft.

The aircraft is made from composites, with its double surface wing covered in Dacron sailcloth. A variety of wings can be used from 10 to 12 m (32.8 to 39.4 ft) in span and 10 to 15 m2 (110 to 160 sq ft) in area, all supported by a single tube-type kingpost and employing an "A" frame weight-shift control bar. The powerplant is a twin cylinder, air-cooled, two-stroke, dual-ignition 53 hp (40 kW) Hirth 2704 engine or 65 hp (48 kW) Hirth 2706. The aircraft has an empty weight of 200 kg (441 lb) and a gross weight of 450 kg (992 lb), giving a useful load of 250 kg (551 lb). With full fuel of 57 litres (13 imp gal; 15 US gal) the payload is 209 kg (461 lb). [1]

The Hirth 2704 and 2706 are a family of in-line twin cylinder, two stroke, carburetted aircraft engines, with optional fuel injection, designed for use on ultralight aircraft and especially two seat ultralight trainers, single seat gyrocopters and small homebuilts.
