Hi all. It's been a while since I've visited/posted.
I'm in the midst of building a Zvezda Yak-9D. I can't speak for the recent Modelsvit production, but their earlier Yak-9DD is much less refined and detailed than the Zvezda effort, which is very complex for a small fighter aircraft kit, with 192 parts, many of which are very small. The kit builds from the inside out, with the whole cockpit and engine (which can have more or less pieces depending on whether you plan to build it exposed or not) mounting on the lower wing, and the multi-piece exterior attaching around it. In this picture, taken when the cockpit was pretty well done, the assembly comprises something over 50 parts.
Since taking the photo, I've discovered that the landing gear struts must be attached prior to the joining of the wing tops and bottoms. Similarly, the tail wheel assembly must be attached to the inside of the separate fuselage bottom part before it is installed.
I'm enjoying the build, and everything goes together reasonably well considering the many pieces. However, tolerances are tight, and there are plenty of opportunities to go awry. The instruction diagrams could be clearer IMHO, and I've had to study them carefully to get things properly located. Bottom line, I think it's going to yield a very well detailed model, but it's in no way a kit that falls together. I'll try to post another photo or two as I progress.
Cheers, Pip
