The end result looks great. Yes, those AK pens are very popular, people were raving about them all weekend at SMW. The suppliers that had them sold out. I think I will try them for things like the base wood colour on cockpit parts, but they are in pretty short supply. However, I don't think they solve the "squiggle" challenge, not unless they do ones with a finer point.
A couple of shots to end the "construction" part of this build. I've taken a few shortcuts especially with the rigging, using etched metal turnbuckles and sliding them into position by running the line from one end to the other on the flat side. After painting them up and if you squint hard enough they don't look too bad.
If you hadn't told me, I wouldn't have noticed! They look fine and I am all for a few shortcuts to get things finished.........
