OK, here are the final pics to stop all this whining..... Sorry for the lighting as I tried a different area of the workshop.
The only thing that I did since the last update was to add the brake lines and allow the sliding canopy to fall off. It's now loose and not quite aligned in these pics. I lost steam with this one when I noticed that the vertical stab is warped and there's something wrong with the main wing alignment too, causing the starboard wing to sit much higher than the port one despite the undercarriage being pretty much level. Not sire where the problem is but it's way beyond fixing anyway.
Seriously, thanks for the interest guys. I learned a lot about Russian colours and hope that this won't be my last Soviet subject.
