Nurtanio NU-85 / NU-90 Belalang
This aircraft is a low-wing conversion of the Piper Cub L-4J.
The prototype, designated NU-85, flew on April 17, 1958, and proved to be such an improvement over the original L-4J that the Indonesian Air Force was having all its L-4Js converted into Belalangs, with the production designation NU-90.
The programme was started in 1959 and the NU-90 became the standard primary trainer at the Air Force Flying School.

Nurtanio NU-25 Kunang / NU-35 Kunang / Lipnur NU-25 Kunang / NU-35 Kunang
Development of the original NU-25 Kunang was started in 1957, to provide Indonesian flying clubs with an economical single-seat ultra-light trainer.
The original tapered wing, with fixed slots, was replaced by a constant-chord wing of 25 percent greater area during 1960. At the same time, the Volkswagen engine has been uprated from 25 to 35 h.p. and a cockpit canopy has been fitted. Now designated NU-35, the Kunang is of conventional wooden construction, with fabric covering.

NUD NU D.38
The Nuri Demirağ Nu.D.38 was a Turkish light civil transport, with twin engines and seating for four passengers, built in the early 1940s. Only one was constructed and flown.
Design work on the Nu.D.38 twin engine light transport began about 1938 and the aircraft was largely completed by 1941, but the first flight was delayed until 1944. Turkey remained neutral through most of World War II, only entering the war in 1945, after the first flight.
The Nu.D.38, manufactured by Nuri Demirağ in Istanbul, was a high cantilever wing aircraft. The wing, of tapered plan and all aluminium alloy stressed skin construction had a built up main spar and a secondary spar. There were pairs of split flaps inboard of the fabric covered ailerons. The fixed surfaces of the tail unit were also aluminium alloy structures with stressed metal skin. The tailplane, set at the top of the fuselage, was strut-braced from below. Control surfaces were fabric covered, with trim tabs.
The fuselage of the Nu.D.38 was an oval cross-section aluminium alloy monocoque, with stressed skin over frames and longitudinal stringers. The crew sat side by side at dual controls in a cabin with side access doors. The passenger compartment seated four, each with their own window, and was accessed through a starboard side door. There was a compartment for luggage or mail in the nose.
The Nu.D.38 was powered by two 160 hp (120 kW) Bramo Sh 14-A4 radial engines, mounted to the main wing spar on steel frames. It had a fixed, conventional undercarriage. A main shock absorber leg was attached to each of the steel engine frames, braced rearwards by a short auxiliary strut. Legs and wheels were enclosed in fairings.
The Nu.D.38 was first flown on 11 February 1944. No further aircraft were produced.
