Он же и самый "дубовый" - пилите, Шура, пилите....
Airfix Su-27 Flanker-B
In my opinion, the most accurate of all the available kits - although one of the worst for fit of parts. Still a little short in length, but acceptable. It certainly looks like a Flanker with a correct curve to the forward fuselage and a slim radome. Wingtip and underwing pylons are best replaced with copies of Hasegawa pylons. Noseleg has a separate wheel to cater for the differences in the debris guard - but it is just butt-joined to the leg which makes for a weak link !
Heller Su-27UB Flanker-C
Same kit as Airfix with new sprue containing two-seat fuselage, cockpit bathtub, extra seat and control column, taller fins and revised nosewheel with different debris guard.
