Overview
The Boeing–Sikorsky RAH-66 Comanche is an American stealth armed reconnaissance and attack helicopter designed for the United States Army. During the early 1980s, the U.S. Army started to formulate requirements for the replacement of its helicopters then in service, which resulted in the launch of the Light Helicopter Experimental (LHX) program. Nearly a decade later, following the refinement of requirements, evaluation of submissions, and the rebranding of the programme as the Light Helicopter (LX) program, during April 1991, the Army announced the selection of the Boeing–Sikorsky team's design as the contest winner, shortly after which a contract for construction of prototypes was awarded. The Comanche was to incorporate several advanced elements, such as stealth technologies, and a number of previously untried design features. Operationally, it was to employ advanced sensors in its reconnaissance role, where it was intended to designate targets for the AH-64 Apache. It was also armed with one rotary cannon and could carry missiles and rockets in internal bays and optionally on stub wings for light attack duties.

Model Kit
As shown on the box art, this is a 1/48 scale Italeri kit made in Italy. The kit is very simple and contains only two sprue trees molded in O.D. green plastic. There is also a clear sprue, some screen for the intakes, and decals.
When looking at the mold quality it seems to be something between the first prototypes and what the design team envisioned as the final variant. While the cockpit glass is cleanly molded, most of the panel lines are too deep and do not match up with the source photos. The cockpit is very simplified with no detail on the inside of the fuselage. The seats, control panels, and rear bulkhead beg for more detail. I should also note that the kit comes without any crew figures. So if you want to build the Comanche in flight to better show off its stealth design, you will need to source the pilot and gunner. There is zero detail in the landing gear bays while the internal weapon storage areas have some basic rib and wiring detail.
The model can be assembled in three different armament configurations:
I am going to build my kit in the "attack" mode, but I am not completely sure if mine will be in flight or on the ground (?). Funny thing is the model is of a fully armed production model but the decals provided are for the two prototypes, go figure. I've always wanted to build this kit since I saw it in a Janes weapons update many years ago. While these 1/48 kits are apparently hard to get, I have seen a couple on-line built into some impressive models. I'm also not quite sure how much extra detail I will add, but follow along and feel free to provide ideas and input towards my build.
Next update will begin the build process... I hope...
