Was that Gazelle G-BAGJ behind XN258?

Btw, according Rotorspot.nl the specific helicopter was only in JA & VH register (Kawasaki-Bell 47G-3B.KH4 ; c/n2171 ; JA7539,VH-AHQ)
… and a small image of the JA7539 at the http://www.geocities.jp/rikichan55/ja7500.html 🙂

Not sure about that because, beside J-20, Soko have had only one other piston engine project – Soko 522 http://sr.wikipedia.org/sr-el/%D0%90%D0%B2%D0%B8%D0%BE%D0%BD_522. (they designed it to exploit a pile of overhauled P&W R1340 fmrYU got from USA during 1950s :))

I’d rather look similarity with constructions the Utva fabricated in Pancevo…

Indeed, the Soko Aviation Industry is almost a brown field now (speaking of plane production – and by the way, none of F16 or any other allies plane didn’t “help” for that happen ;-), but as far as I know J-20s were maintaned & overhauled by http://www.vzmoma.com/engleski/index.htm.
How about to start from there with your project?

I’m glad to be of help.

There’s one in Croatia, but in bad condition until now http://www.hrcappuccino.org/ – click on left “Okohodci” and then look 10th thread from the bottom list /pics taken back in 2002

Looks like we have a family project now 😀

Go ahead, that way you won’t just prevent some personal memories from oblivion but also help preserve part of aviation history as well.
