About the Maule M-4

The Maule M-4 is a rugged four-seat tailwheel aircraft built by Maule Air in Moultrie, Georgia, since the 1960s and known for exceptional short-field performance. Designed by Belford Maule, a pioneer in STOL (Short Takeoff and Landing) technology, the M-4 family includes variants like the Rocket, Jetasen, and Strata Rocket, powered by engines ranging from 145 to 220 horsepower. With its fabric-covered steel tube fuselage, high wing, and strong landing gear, the M-4 thrives in backcountry strips, gravel bars, and unprepared surfaces where most aircraft fear to tread.

Takeoff rolls under 400 feet and landing distances under 500 feet are routine, making it a favorite among bush pilots, hunters, and remote operators in Alaska, Canada, and the Mountain West. The type's simplicity and field-repairability have kept examples flying for decades, often in harsh environments far from maintenance facilities. While cruise speeds are modest (around 130 knots), the M-4's real mission is getting in and out of places other aircraft cannot reach, not covering distance quickly.
