The Windward Performance SparrowHawk is a single-seat ultralight glider from the US manufacturer Windward Performance and the first glider made entirely of CFRP .
It was designed by Greg Cole according to the regulations for ultralight gliders in the USA, which stipulate an empty weight of no more than 70 kilograms. As the first and with a combination of five different wing profiles, the SparrowHawk achieves the performance of a club class glider, despite its low mass and only 11 m wingspan , which typically has a wingspan of 15 m and an empty weight of 200 to 300 kg. Prepregs were used to achieve a high proportion of fiber volume , which enables the lightweight construction .
The prototype took off on its maiden flight in 2001.
Jim Payne set eight national and international records in the ultralight glider class with the aircraft in 2009.
