Developed by Pipistrel as one of the first self-launched sailplanes in the microlight category the design used the wings of the Pipistrel Sinus with a new two-seat side-by-side fuselage. To enable the Taurus to self-launch a pop-out propeller is mounted on the rear fuselage driven by a Rotax 503 piston engine. In 2007 the company developed the Taurus Electro with the piston engine replaced by a permanent magnet synchronous three-phase brushless motor.
Variant with a Sinedon 40 hp (30 kW) electric motor replacing the piston engine; first flown in 2007. It was the first electric motor glider to achieve series production.
Unpowered variant without engine fitted.
Taurus Electro G2
Introduced in February 2011 as a two-seat self-launching sailplane, powered by a 40 kW (54 hp) engine and lithium batteries. Powered endurance is 17 minutes, intending to allow for self-launching to an altitude of 2000 m (6500 ft), after which the engine is retracted and the aircraft then soars as a sailplane.
Taurus G4 on display
One-off twin fuselage, four seat version, based on the Taurus Electro and acting as an engine development test bed for their forthcoming Panthera four seat hybrid. It has a 150 kW (201 hp) motor mounted on the central wing section between the fuselages. With two people on board, it was the winner of the Green Flight Challenge held in September 2011, covering 403.5 passenger miles per gallon equivalent and receiving the $1.35 million prize donated by NASA.
