Lembaga Industri Penerbangan Nurtanio 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.
