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.
