[hesham]

Hi,

we know very well the Indonesian LIPNUR,it was the Department of the
Indonesian Air Force,Nurtanio Aircraft Industry,and here is its X series;

X-01 Sikumbang NU-200 was COIN aircraft.
X-02 Kumbang 260 was four-seat utility aircraft.
X-03 Belalang 85 was military trainer aircraft.
X-04 Kunang 25 was light sport aircraft.
X-05 Super Kunang 35 was developed from above.
X-06 Kindjeng 150 was sport autogyro.
X-07 Kunang 50 was developed from Kunang 35.
X-08 Manjang was a helicopter.
X-09 Sikumbang NU-225 was COIN aircraft.

Thanks Hesham. By the way, many of these designs were originally attributed to AURI or LAPIP which predate LIPNUR.

In his book, Harapan dan Tanggapan Pemerhati dan Mitra, R.G.W. Senduk gives a slightly different list for these 'X' numbers. I've incorporated these differences into my type list below:

X-01 - NU-200 Sikumbang (Bee), light armed reconnaissance aircraft
- aka Si Kumbang, prototype with 200 hp DH Gipsy Six Srs.1
- NU-225 Sikumbang aka Sikumbang-02, 225 hp Continental O-470
- NU-260 Sikumbang, [? 260 hp Continental IO-470 ?]

Dear Hesham and Apophenia,
thank you for the X series from Indonesia, very interesting stuff ;D.
In my notes I have a first flight date of 15 January 1965 for X-07/NU-50, but I have never seen any picture of this 2-seater and I honestly doubt whether it was actually built/flown.
Any ideas!
