I worked a little on the Su-9, landing gear, correct masking, started the missiles
Looking good. It appears you had no issues during construction. Did the kits come with the masks?
No, they didn’t.
For the Su-9 I got a set from Montex and the Su-11 from Eduard.
No, no issues with the construction.
But the cockpit lacks detail, at this scale and given the size of the aircraft, I would expect better detailing.
The are other extras if you want to pimp it.. engine, wheels, air scoops and pitot tubes.
