Maule M-7 / MX-7 / MXT-7
In 1981, Maule installed an IO-540-W1A5D out front of the M-5 and began delivering the M-6, also available with EDO floats. Two years later the model would morph into the M-7 and in 1989, the M-8. In 1991, the company experimented with a turbine Maule, installing an Allison 420 shp 250-B17-C and eventually offered the design in both taildragger and tricycle gear configurations. The family continues to create endless variations and improvements on the original airframe, with the original fuselage jig designed by founder B.D. Maule still in use in 1975.

Maule
Belford D. Maule, or “B.D.”, as everyone knew him, was born November 4, 1911 in Old Fort, Ohio to farming parents. Not caring much for farm life, he left at the age of 15 to live in Salladasburg, PA. with an uncle and aunt who owned a garage and tea room. There he demonstrated his mechanical ability by building a tractor, and by motorizing an ice cream freezer and an ice saw, among other things.
B.D. joined the Army when he was 18 and was assigned to the 19th Airship Company at Langley Field, Virginia. While working on dirigibles, he found time to design and build his first airplane, a single seat midwing monoplane powered by a Henderson 27 HP motorcycle engine, known as the M-1. Starting with the airplane on floats, and later on wheels at the Salladasburg farm, B.D. taught himself to fly. (Regulations weren’t as strict in those days.)
Following his stint in the Army, B.D. moved back to Pennsylvania and became a family man, marrying June Aderhold in 1934. June and B.D. located in Jersey Shore, Pennsylvania and built their own home there in 1936. Note that Jersey Shore is not only June’s birthplace but is also midway between Lock Haven (Piper Aircraft) and Williamsport (Lycoming Aircraft Engines). This was an area in keeping with B.D.’s interest in aviation. B.D. went to work for Lycoming, and in 1939 designed and built “the Hummer”, a low cost mechanical starter for light aircraft. (Many airplanes did not have electrical systems back then.)
In 1940, the Maule family moved to Jackson, Michigan. Mechanical Products Company was formed to manufacture the Hummer starter (Piper and the Continental Engine Company had shown an interest). In 1941 the B.D. Maule Company was formed in Napoleon, Michigan to build a light aircraft tailwheel which B.D. had designed. The steerable, full-swiveling tailwheel, is still being manufactured by Maule, in an improved form. With the advent of World War II, the starter business waned, and tailwheels were in demand as well as subcontract work to support the war effort.
As a diversion during the latter part of the war, B.D. designed a man-powered glider with flapping wings, known as an ornithopter. He claims to be the first (and is probably the last) person to have successfully flown such a device.
In 1946, B.D. and June purchased a farm near Napoleon, Michigan. With the help of their two oldest children, they converted it to an airport. In the process, they had the dubious honor of leveling a dog race track which had been operated by Al Capone. The airport flourished, being used for flight training during the initial post-war aviation boom.
Maule Aircraft Corporation formed by B. D. Maule at Jackson, Michigan, to manufacture M-4 four-seat light aircraft; production transferred to Moultrie, Georgia, September 1968. The airplane manufacturing business that received its first FAA type certificate in 1961. Prototype flown September 8, 1961, produced as M-4 with 145 hp Continental engine, as M-4 Rocket with 210 hp Continental. M-4 Strata-Rocket with Franklin engine led to M-5-220C Lunar Rocket, flown 1 November 1971, while M-4 Rocket became M-5-210C; M-5- 235 with 235 hp Lycoming 0-540 engine also built. Current name Maule Air Inc., offering large range of four- and five-seat lightplanes for recreational and business uses in the M-7, MT-7 and MXT-7 series. Over 2,000 Maule aircraft built since 1961.
The Maules are built on the Air Force’s abandoned Spence Air Base, just east of Moultrie, Georgia. They had been building airplanes for years in Jackson, Michigan, when in 1972, a particularly severe winter convinced them to seek a warmer haven. Moultrie was looking for industry. The first production model, known as the Jetasen M-4 was delivered in April 1962. Then, as now, all Maules are constructed in Moutrie, Georgia.

A monowing using weight shift and rudder control. The separate rudder is all flying and there are no ailerons, spoilers or wing warping to achieve roll. Construction is of aluminum tubing covered with dacron on the wings and tail surfaces. Power is a Yamaha mounted in pusher position forward of the wing. A 2:1 reduction unit turns a two-blade, wooden Ritz propeller. Fuel is carried in a plastic tank mounted above the wing. LANDING GEAR: Tricycle type shock mounted with spring action and a bicycle squeeze-type brake. The main and nose wheels are 16 inches in diameter.
In 1981 the complete MAC LST 400 sold for US$2995.
All MAC ultralites convert to floats in minutes. Mac un-breakable floats retailed for $495.00 and fit any ultralite
that has a main gear axle.
Each MAC. LST 400 series aircraft is built with 90% straight tubing joined with special fittings to allow faster assembly time, easier parts replacement and lower cost all around. Replacement parts consist of one straight tube to be cut and drilled to size. Special features are a spring shock system, sturdy all round construction. Simple engine mounting, quick folding for storage, all bags and covers included.

Mathews Pup
Single seat single engined biplane with three ¬axis control. Wings have unswept leading and trailing edges, and constant chord; conven¬tional tail. Wings braced by struts and transverse X cables; wing profile double ¬surface. Undercarriage has three wheels in tail dragger formation. Tailwheel steering. Aluminium tube framework. Engine mounted between wings driving tractor propeller.
Like the CCC, the PUP from Lyle Mathews is only sold as a set of plans. The PUP (Perfect Ultralight Plane) is a single seater biplane with its lower wing of shorter span than the top. The top wing is supported by a tubular framework which forms the cockpit and also acts as the mount for the tractor engine fitted in the nose of the PUP and on which the two triangular main¬ gear legs are mounted. The wings are sup¬ported by interwing struts and flying and landing wires in an X configuration, in the tradition of the old biplanes. The convention¬al tail and the steerable tail wheel are carried on a rectangular section, aluminium spar of 1 x 3 inch (25 x 76 mm). For simplicity the PUP has a metal structure built with gussets and pop rivets. The prototype formed its first flight at the beginning of 1983 using a Lloyd 22hp engine which Lyle Mathews then re¬placed with a Kawasaki TA440.
Plans cost $15 in the US and Canada, $20 elsewhere in 1982.

Mathews CCC
Single seat single engined high wing mono¬plane. Wing has unswept leading and trailing edges, and constant chord; cruciforin tail. Undercarriage has three wheels in tricycle formation. Aluminium tube framework. En¬gine mounted below wing driving pusher propeller. Other details depend on builder’s specifications.
Lyle Mathews sells sets of plans of ultralights for homebuilders and this machine which he has designed himself leaves the choice of weight¬shift, hybrid or conventional control system to the constructor, depending on how he or she builds the control surfaces. Lyle Mathews’ CCC (Cross Country Cruiser) can be described as a high wing monoplane with a rectangular wing form and a cruciform tail with tricycle undercarriage; it uses ‘tradition¬al’ tube and fabric construction. It is intended to receive 15 to 30 hp range engines in pusher configuration, mounted on the rear tubes of the pilot frame. The plans are sold in the USA and Canada for $15 and in other countries for $20 in 1982. The data for each CCC depend on how the constructor has chosen to build the aircraft.
