N.Stroud - Indonesia's fledgling insects
The Sikumbang awaits another flight from Husein Sastranagara Air Force Base at Bandung, with an AURI Consolidated PBY in the background. The pilot sat just above the leading edge under a sliding cockpit canopy which provided an excellent view in all directions.
An air-to-air study of the NU-200, the first original design of the Air Force's Experimental Section which commenced flight testing in August 1954, showing the aircraft’s straight-tapered wing, which was of single-piece wooden construction with an aspect ratio of 6-5:1. Contemporary press reports highlighted the NU-200’s similarity in intended role to the USA’s Fletcher FD-25 Defender COIN aircraft, which was not adopted by American forces.
This aircraft is today mounted on a pedestal at the entrance of the Nurtanio factory.
Major Nurtanio Pringgoadisuryo stands beside the NU-200 Sikumbang on its roll-out at Bandung in the summer of 1954. For this article we have used the Indonesian custom of putting the surname first.
The sole NU-200 Sikumbang aloft after its first flight in August 1954. Bearing a large “X” on the tail to denote its experimental status, the “Bee” also carried the nation’s red-and-white pentagon marking and the serial “01”. The bare-metal fuselage was wrapped with a yellow band and the upper surfaces and fin were orange-red.

The cockpit of the NU-200 was relatively simple, but included all the necessary basics, including altimeter, r.p.m. gauge, airspeed indicator, turn-and-bank indicators, compasses, fuel gauge, climb meter and manifold­pressure gauge. The throttle box was located on the port side, above the trim-control equipment, seen at LEFT.
Belalang Model 90A - переоборудованный учебно-тренировочный Piper L-4 с улучшенными летными характеристиками.
The upside-down Cub - with its name and a grasshopper motif on the forward fuselage, a production NU-90 Belalang meanders over the Indonesian countryside. Quite why the Indonesians considered the low-wing Belalang an improvement over the high-wing Cub from which it was derived remains something of a mystery.
The series version of the Belalang, the NU-90, with redesigned cockpit canopy and other changes.
The tapered wings and swept fin of the NU-25 Kunang were replaced in stages on the NU-35 Super Kunang, probably built using the same airframe, initially with a constant-chord wing of 25 per cent greater area and later an unswept fin, as seen here. An uprated 35 h.p. Volkswagen engine was also fitted.
Designed as an economical single-seat ultra-light training aircraft for pilots of very limited experience, the NU-25 Kunang first flew circa 1957-58, and was roughly equivalent to the Druine Turbulent in terms of size and performance. The same aircraft, “04”, was later fitted with a 35 h.p.engine and an enclosed cockpit with canopy.
