In February, 2003, Groen Brothers Aviation formed a subsidiary, American Autogyro, to produce gyroplanes for the “kit-built” market. American Autogyro’s two-place Sparrow Hawk Gyroplane is also offered as a complete, turn-key aircraft in an Airborne Patrol Vehicle (APV) model. The SparrowHawk APV is an excellent entry-level airborne surveillance vehicle for many law enforcement agencies. American Autogyro also sells a Stabilization Augmentation Kit, designed to dramatically improve in-flight stability and safety for what has been the most popular competing kit gyroplane in that market. More than 120 SparrowHawk Gyroplanes and Sparrow-Hawk/P modification kits have been sold.
