Maule aircraft are known for being a good value, easy to fly, reliable, and long lasting. The model M-7-420 is the world’s smallest turboprop powered aircraft.
Maule aircraft have been used as trainers, by the military, as sight-seeing aircraft, by police departments and as recreational aircraft. They have been equipped with skies and floats. Their short take off and landing abilities are appreciated by bush pilots in remote areas of the world.
Maule aircraft were conceived by Belford D. Maule in 1952. He designed them from the start to be high performance utility aircraft which could be flown from small, unimproved air strips. The aircraft first took to the sky in 1957.
The Maul Aircraft Corp. was officially formed in 1962. Their first model, the M-4, became instantly popular. By 1968 the aircraft were upgraded with engines that produced over 50 percent more power. A new plant was opened to accommodate additional production.
Maule aircraft continued to be refined and improved through the years. Engine power has increased, and controls enhanced for better response. By 1990 the aircraft were being sold throughout the world. By the mid 1990’s Maule aircraft reached the no. 3 position of best selling single engine aircraft in the United States, producing over 60 aircraft a year.
Flying the Maule Aircraft
The cockpit of a Maul aircraft is spacious for the largest of people, and comfortable. The interior is brightly lit, and visibility is excellent through the large side windows.
When starting a newer Maul aircraft that uses a three bladed propeller, you will find it extremely smooth running. Not only is the idle smooth, but the aircraft is smooth throughout its operational range.
Taking off happens in the blink of an eye in this STOL aircraft. A Maule aircraft will lift its tail with just a short roll and be ready to rotate after about 200 feet. Very little rudder is necessary to counter propeller torque. Although a Maule aircraft will get off of the runway in a hurry, with the piston engine its maximum climb rate is about 1,250 fpm. The good thing is that it will climb at just about that same rate from a high altitude runway, or when fully loaded. However, higher altitudes will lengthen the takeoff run.
Landings in a Maule aircraft require some effort. The factory recommends 65 mph as the approach speed. Dropping the speed under 62 mph will result in it sinking at a surprisingly quick rate. Flying an approach at above 70 mph will make it hard to bring down. Small throttle corrections at slower approach speeds results in excellent aircraft control during steep approaches. During flair, one must be ready to apply throttle instantly to prevent the Maule aircraft from dropping from the sky.
Once the Maule aircraft settles down on the runway, it steers like most other tail dragger aircraft. Things happen slowly due to its slow landing speed and quick deceleration. However, the large aircraft profile make it susceptible to strong cross winds. Brakes, rather than rudder, are best used to keep the aircraft from weathervaning.
A total of over 2,500 Maule aircraft have been built to date.
