The EEL ULF 2 is a West German low-wing, conventional landing gear, single-seat motor glider that was designed by Dieter Reich and is provided in the form of plans by Entwicklung und Erprobung von Leichtflugzeugen (English: Development and Testing of Light Aircraft) for amateur construction.
The prototype was built in 1993 by Anton Quanz with Horst Fischer building the engine installation and electrical system. The ULF 2 first flew in October 1993.
The ULF 2 is predominantly constructed from northern pine or Douglas fir, with spruce and birch plywood and covered with doped aircraft fabric. The engine cowling, wing tips and fairings are made from fibreglass. The 11 m (36.1 ft) span wing features a Wortmann FX 63-137 airfoil and top surface spoilers. The aircraft mounts a ballistic parachute full-aircraft recovery system. The landing gear is conventional with a steerable tailwheel. The 54 cm (21 in) wide cockpit features a pilot seat inclined at a 33° angle.
The recommended engine is from a Citroen Visa automobile, which consumes 4.0 l/hr (1.06 US gallon per hour) and produces 24 kW (32 hp). The engine retains its automobile muffler and catalytic converter, runs on unleaded auto fuel, stored in a fuselage-mounted aluminium fuel tank with a capacity of 33 litres (7.3 imp gal; 8.7 US gal). The propeller is powered via a belt reduction drive. The muffler system allows the aircraft to comply with the ICAO Annex 16, Chapt. 10 noise requirements of 55 dB(A).
