About the Chaser Aircraft Chaser 75

The Chaser 75 is a single-seat, single-engine aerobatic taildragger designed and manufactured by Chaser Aircraft in the United States. Introduced in the early 2000s as a Light Sport Aircraft, the CH75 occupies a niche in the sport aviation market as an affordable, nimble platform for recreational flying and basic aerobatics. Built around a welded steel tube fuselage with fabric covering and powered by a Rotax 912-series engine producing around 80 horsepower, the Chaser 75 emphasizes simplicity, low operating costs, and spirited handling characteristics. Its light empty weight of approximately 600 pounds and maximum takeoff weight of 1,650 pounds place it squarely in the LSA category, making it accessible to pilots holding a sport pilot certificate.

The aircraft's aerobatic capability sets it apart from many LSA designs, which are typically limited to normal category operations. The CH75 is stressed for positive and negative G-loads, allowing loops, rolls, and other basic maneuvers within its approved envelope. Its relatively low stall speed of 39 knots in landing configuration and never-exceed speed of 135 knots define a forgiving flight envelope suitable for pilots building tailwheel and aerobatic experience. The tandem seating arrangement (single-seat in most configurations) and conventional gear demand active pilot technique, particularly during takeoff and landing, rewarding stick-and-rudder proficiency.

SkyMeter has tracked flights across airframes and operators, with the largest observed operator.
