This is my second Arma Hobby kit to build, and I continue to be impressed. The detail – from the cockpit to the panel lines and access hatches – is tremendous. In fact, for 1/72 scale, it is almost a case of over-engineering! It took me about as long to build the cockpit and close the fuselage as it did to finish, paint and weather the aircraft!
The box and instructions include colored art for four different aircraft, accompanied by nicely printed decals that performed well. Because of some of the differences between the aircraft depicted in the decals, and the fact that many of the sprues are evidently intended to allow the building of other P-39 versions, I would recommend after you select your aircraft, run through the instructions carefully and determine which parts to include. There are places where you are required to fill in some engraved access hatches and inlets for the depicted N version, if you want to be technically accurate.
