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][2]
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][3]
