I have gotten a good start on my first Il 2. This is the second Accurate Miniatures model I've built (the SBD/A-24 was the first) and it is certainly engineered differently than other kits. You build this in some interesting sub-sections that don't seem to make sense at first glance, but if you follow the instructions it goes together quite nicely.
I started by painting the cockpit and fuel cell assembly and setting it aside to dry. Next is to glue the two main fuselage halves together.

The next steps are to assemble the radiator and spars to the lower wing center section. I found that the center section skin was molded rather flat and I used CA glue to fasten the spars tightly. The spars have the correct dihedral and are able to help give the center section the correct shape. The last step here is to glue the cockpit assembly to the center section assembly. Next was to assemble the engine cowling halves and the oil cooler inlet duct. This is one of the interesting designs of this kit but it does need a tiny bit of filler to fair all of the cowling parts correctly.

Just for fun I slid the upper wing panels and horizontal stabilizers into the assembled fuselage to check the fit. This, too, looks like it will fit quite well.

This is proving to be an easy and quick build so far. Not counting waiting for paint to dry I've only spent a couple of hours on it to this point.
