I'm calling this one done, and I think it does evoke what a CH-37 looks like. Menacing to those who worked on and flew it, if not to the enemy, though they did do time in Viet Nam until the Skycrane and Chinooks were available for heavy lift.
I put in the markings of one I worked on in 66 to 71 in the Cal ARNG 49th Avn Bn at Stockton, 0-50643 after it was repainted in the newer non gloss OD. I used ANA 613, looks close to what I remember. What minimal decals needed were done on my Alps MD-1000 after drawing them in Corel X4.
I think Special Hobby did a fine job of capturing the shapes and the fit was pretty good. The cockpit assembly was too wide for the fuselage, especially at the seat tops. As usual I did not use all of the PE parts, to fiddly and unlikely to be seen if they are on, like all the climbing handles. I know they are there on the real thing but I can't see them in most photos. Assembly was made more difficult by weak instructions as to placement and no definite fits on complex assemblies where errors can become additive. And then I lost two of the augmentor tubes and had to make a two part mold and cast replacements in order to bring things to a timely close.
More pictures of the build at the Helicopter GB in progress now.
