LOL, I've got two of the 1/32 Flankers sitting behind me right now in various states of unfinished...
The nose cone fit on the B has had me stymied for months as I just can't think up a fix for it- either I reshape the cone with heat (scary thought) or I pack it full of milliput and start grinding and sanding it down to match the fuselage contours. Otherwise, that bird is ready for painting. The C got sidetracked by some other GB entries (Frogfoot and MiG-21). I've got several Linden Hill and Begemot decal packages for each if I ever get back to them.
If you haven't tried one, look into Trumpeter's 1/32 Su-25UB as it's a fantastic kit with excellent details all the around and there's a kick-ass resin cockpit set for it as well as PE. I've spent as much time on painting the Frogfoot's cockpit as I have spent on the entire MiG-21 project.
This is my main contest entry and has been getting all my love for a couple of months now... two weeks to finish it.
