About the Pipistrel Virus SW 121

The Pipistrel Virus SW is a Slovenian-designed two-seat ultralight and light sport aircraft that has earned a reputation as one of the most efficient and elegant motorgliders in its class. Built by Pipistrel Aircraft, a pioneer in composite construction and electric aviation, the Virus SW combines a sleek composite airframe with a modest Rotax 912 piston engine to deliver exceptional fuel economy and glide performance. With a maximum takeoff weight of just 1,323 pounds and a stall speed below 40 knots, it qualifies as an ultralight in many jurisdictions while offering cross-country capability that rivals much heavier aircraft.

The SW (short-wing) variant trades some of the original Virus's soaring performance for improved cruise speed and handling, making it popular among European touring pilots and flight schools seeking low operating costs. Its clean aerodynamics yield a cruise speed around 120 knots on less than 5 gallons per hour, and the aircraft's docile handling and excellent visibility make it a favorite for both training and personal travel. The Virus family has won numerous efficiency competitions and set multiple records for fuel economy, cementing Pipistrel's status as a leader in sustainable general aviation.
