The Groen ShadowHawk was a proposed American autogyro that was under development in the mid-2010s by Groen Aeronautics of Midvale, Utah for the surveillance role. The aircraft was intended to be supplied complete and ready-to-fly.[1] Active in 2015, by November 2017 the project's webpage had been taken down and development has probably ended.[1][2] Design and developmentThe ShadowHawk was based upon the earlier Groen Hawk 4 and its successful employment in the surveillance role at the 2002 Winter Olympics in Salt Lake City.[1] The design was to feature a single main rotor, a two-seats-in side-by-side configuration enclosed cockpit with a bubble canopy, tricycle landing gear, plus dual tail casters and pusher configuration engine. The design includes a two-bladed rotor and a four-bladed pusher propeller.[1] Specifications (ShadowHawk) {{Aircraft specs
