Looks good so far Alfa. Halinski kits really are a joy to build. At this point I pretty much avoid any other publisher unless that publisher has a unique subject that Halinski has not yet designed.
One thing that you need to watch out for with Halinski's kits though is the bulkheads. I assume that everything is designed on a computer, and it is designed to be PERFECT. This means that absolutely any slip of the knife or misshapen part will likely cause a bit of a mess with any of the surrounding parts. (I ruined the Halinski Su-27 in this manner.) With the bulkheads though, I find it hard to hide there existence. Usually you can see a that the part conforms to the bulkhead at the fuselage segment seems, but each segment tends to collapse slightly inward. This gives the appearance of bulges at each seem.
However, you can solve the problem by doing two things. First, shape the bulkhead SLIGHTLY. By this I mean sand the edges to match the slope of the fuselage. If the fuselage is shrinking into a cone at the tail, sand the edge of the rear of the bulkheads to be every so slightly smaller than the front. Flip this if it tapers to the nose, or leave the edges perpendicular if the segment does not taper at all.
Second, make sure each segment is completely formed before glueing it. You should not have to hold a segment around its bulkhead to make it hold its shape. You should spend lots of time "curling" the paper and rounding it so that it will almost conform to the shape of the bulkhead without it having to be held into place. As a rule of thumb, if you have to hold it, it has not been preshaped enough. Use the edge of a table for large curves, and roll pencils and burnishing tools over the paper (with a semi-soft surface underneath...erasers work well.) to make more accurate small curves.
Ok I will stop blabbing now. You may already be using these techniques, but I just thought that I would share my discoveries with you in the case that they might help. Good luck building the rest of her. I look forward to building this kit myself, so I cannot wait to see your results.
