MWfly SPIRIT SKY LINE non-cerified Aeronautic Engines are 4-cylinder horizontally opposed (boxer type) liquid cooled motors manufactured to the highest standards to meet application requirements in a wide range of LSA and experimental single-engine or twin-engine airplanes and other aircraft (STOL, helicopters, gyrocopters, hang gliders, seaplanes and drones). These engines have been designed for long-distance touring use and can be supplied with clockwise or anticlockwise rotation, both in tractor and pushing configurations. Rotation is designated by the letters "R" or "L" at the engine model code. The rotation must be specified at the time of ordering. Their large displacement, combined with the high torque values obtained at low rpm, guarantees great flight comfort and low fuel consumption.

SPIRIT SKY LINE different models are offered with direct or geared drive transmissions (depending on the model) and deliver 100, 122, 135 & 140 HP.
