Mansyu Ki-79
The Mansyu Ki-79 was an advanced trainer based on the Nakajima Ki-27 fighter. The Nakajima Ki-27 had been the first monoplane fighter to enter service with the JAAF, but by 1942 it was virtually obsolete, and a number had been converted to act as trainers. Mansyu went one step further, designing a dedicated training version of the aircraft, the Ki-79. Initiated in 1942 in China. It came out in four variants and remained in production until the end of the war.
The Ki-79 entered production in two versions. The Ki-79a (Army Type 2 Advanced Trainer Model A) was a single-seat trainer, while the Ki-79b (Army Type 2 Advanced Trainer Model B) was a two-seat trainer with tandem cockpits. The two separate cockpits took up about the same amount of space as the long canopy over the original single cockpit, with the front windscreen in the same place as on the single-seater. Both models shared the same all-metal construction as the Ki-27, were powered by the 510hp Hitachi Ha-13a engine and were armed with one forward firing 7.7mm machine gun.
During 1943 the Ki-79 was used to equip the Sendai and Tachiarai Army Flying Schools and the Tokorozawa Army Aviation Maintenance School. The Ki-79b was also used by the Tokyo, Otsu and Oita Army Boys Flying Schools, where they were used to give high school students a taste of flying. The Army designation was Mansyū Army Type 2 Advanced Trainer.
During 1944 the JAAF founded a number of Flight Training Companies, and although a total of 1,329 Ki-79s were built numbers began to run short. Mansyu responded by designing the Ki-79c and Ki-79d. Theses aircraft used a new airframe, with a steel framework covered by a plywood skin, designed to reduce the amount of duralumin needed in their construction. The Ki-79c matched the Ki-79a, while the Ki-79d matched the Ki-79b. Both types had only just entered production at Mukden when the war ended.
In the post-war period the Ki-79 was used as a trainer by the Chinese Communists. A large number of aircraft were captured intact in Manchuria after the Soviet invasion. The Communists hired Manchurian and Japanese pilots to get the training programme under way, and the Ki-79 became the first standard training aircraft for the People’s Liberation Army Air Force.
The Ki-79 was also used by Indonesian forces fighting the Dutch on Java and Sumatra, where a number of aircraft were reconstructed after being found on Japanese scrap-heaps. A Ki-79b became the first aircraft to be flown by the Indonesians.

Mann & Overtone 1910 monoplane
1910 Mann & Overtone monoplane was designed and built by Mann & Overtone Ltd in the UK.
Manning Comet
H. W. Manning had little experience with airplane design, but using the financial resources of his gas mantle business, Manning and his sons built an airplane they called “Comet I”. Son Jack made unimpressive test flights, but he convinced his father to build a larger plane, dubbed “Comet II”. They unsuccessfully displayed the machine in Baker City, Oregon on July 4-5, 1910. During the summer the Mannings attempted flights near Astoria, Oregon, and they also built a “Comet III” before giving up as constructors.
Mann, Egerton & Co Type B
At its Norwich factory built 12 Short 184 or Mann, Egerton Type A seaplanes, and from this developed own Type B seaplane powered by Sunbeam engine.
Mann and Grimmer M.1
Seventeen-year old R. Mann designed M.1 two-seat fighter-reconnaissance biplane, built with assistance of R. P. Grimmer and test-flown at Hendon February 19,1915. Conventional radial engine, nose-mounted, but facing aft so that propeller shaft extending through fuselage drove interplane strut-mounted twin pusher propellers via chain drives. Wrecked November 16,1915, development discontinued.

MFI MFI-15
MFI had been developing an airplane for some time, for artillery spotting and liaison operations and training, and which made its maiden flight on 11 July 1969 (SE-301), promised to be ideal for both of these purposes. Designed by Bjorn Andreasson, the plane could easily be equipped either with a nose wheel (this version being known as the MFI-15A trainer) or with a tail wheel (the artillery spotting version designated MFI-15B). The Swedish Air Force decided to purchase the Beagle Bulldog while the MFI-15, later renamed Safari, test program was still in progress. The plane was converted into an efficient weapons carrier by increasing the engine power and making some structural modifications as the MFI-17.
MFI BA-12 Sländan
Designed and constructed by Bjorn Andreasson and Rudolf Abelin, the Malmö Flygindustri (MFI) BA-12 Sländan is a single seat ultralight of pod and high boom configuration and with a butterfly tail. Designed and built in Sweden in the 1980s, the Sländan (English: Dragonfly) was the first Swedish microlight apart from glider based types. It is built from composite materials, with a square section beam formed in two halves supporting the engine well ahead of the wing leading edge and extending aft continuously to the tail. The wings, rectangular in plan and with a high aspect ratio (10:1), are attached to the beam with dihedral of 1.5 degrees. Ailerons cover 30% of the trailing edge. The wing has two pressed spars, foam filled glass fibre ribs and Kevlar filled glass fibre sandwich skins. The butterfly tail surfaces are also rectangular and assisted by a short ventral fin with the same chord as the tailplane.
The round nosed, single seat cabin is formed from six bonded pieces and mounted on the boom with its windscreen at the wing leading edge, placing the pilot below the wing at about one quarter chord. The sides are normally open though complete enclosure is an option. On each side a forward leaning bracing strut runs from the lower rear cabin to the front wing spar. The Sländan has a short, fixed, tricycle undercarriage with a steerable nosewheel; the mainwheels, fitted with brakes, are mounted on straight steel cantilever legs from the lower fuselage. There is a protective tailskid on the tip of the underfin.
The prototype Sländan was initially powered by a (21 kW) (28 hp) König SD 570 4-cylinder two-stroke engine though there were plans to replace this with a Lotus Magnum 2.25 when this type became available. At least three examples have been fitted with Rotax engines.
The Sländan first flew in 1984 and by February 1985 MFI were assembling five more. It was agreed that later aircraft should be produced by the Royal Swedish Aero Club using MFI’s moulds and tools. It was intended to market the Sländan in both flyaway and kit form. At about the same time, in a collaboration between MFI and FFK Aerotech, Andreasson was developing a slightly larger, two seat version called the FFV Aerotech BA-14 Starling.
Three Rotax powered, Swedish registered Sländans appeared on the mid-2010 civil aircraft registers of Europe.
