The Maule M-5 is an American four-seat cabin monoplane designed and built by the Maule Aircraft Company.

Design and development

The M-5 was a development of the earlier Maule M-4 with improved STOL performance. It has a 30% increase in flap area and enlarged tail surfaces.

Two prototype M-5s flew in 1971, one powered by a 210-hp (157kW) engine, the other with a 220-hp (164kW) engine.

The M-5 is a steel-tube and fabric high-wing braced-monoplane with a cantilever tailplane with a single fin and rudder. It has a fixed-tailwheel landing gear and an enclosed cabin with two rows of side-by-side seating for a pilot and three passengers. The aircraft entered production in 1974 and was named the Strata Rocket and the Lunar Rocket. A generally similar M-6 Super Rocket was also developed with a 3-foot-longer (0.91 m) wingspan and more fuel capacity, smaller ailerons and larger flaps.
