S-2F3AT Turbo Tracker

The S‑2F3AT Turbo Tracker, produced by Marsh Aviation, is a modernized version of the classic Stinson Model 2 that first flew in the 1930s. Marsh began the conversion program in 2012, aiming to preserve the aircraft’s timeless lines while delivering contemporary performance and reliability. The “Turbo Tracker” retains the original high‑wing, fabric‑covered airframe but replaces the obsolete 140‑horsepower radial engine with a fuel‑efficient 300‑horsepower turbo‑charged Continental CD‑300 diesel powerplant. This upgrade provides a cruise speed of 145 knots, a service ceiling above 15 000 feet, and the ability to run on readily available Jet‑A fuel, dramatically extending range and reducing operational costs. Additional improvements include a glass cockpit with Garmin G3X Touch avionics, modern composite propellers, and reinforced landing gear suited for both paved runways and short, unprepared strips. The aircraft’s versatility makes it popular among bush pilots, flight schools, and vintage‑aircraft enthusiasts who desire classic aesthetic with modern safety features. Its significance lies in bridging heritage and technology, demonstrating how legacy designs can be revitalized for contemporary general‑aviation markets while maintaining the nostalgic appeal that originally made the Stinson a beloved workhorse today.
