The Windward Performance DuckHawk is an American mid-wing, single-seat, 15-metre class glider, that was designed and produced by Windward Performance of Bend, Oregon.[1]
Since 2016 the aircraft has been no longer advertised as available by the manufacturer.[2]
Design and development
The DuckHawk is a development of the Windward Performance SparrowHawk and is intended as a higher performance glider than its predecessor, with very high structural limits and Vne. The DuckHawk has less than 10% parts commonality with the SparrowHawk. It features a cantilever wing, a single-seat enclosed cockpit under a bubble canopy and retractable monowheel gear.[1][3]
The aircraft is made from preimpregnated carbon fiber. Its 15 m (49.2 ft) span wing employs a Greg Cole-designed airfoil, has an area of 80 sq ft (7.4 m2) and an aspect ratio of 30:1.[1][4]
