They are the best 1/35th Hueys on the market; too bad they only make the C model and not the U, H, or N. For those you have to use an old 1/32 Revell or the newer Panda versions (which I hear are terrible; the rivets are waaaay too big and I hear the fit is poor (I have two but haven't put either one together yet).
They all have errors but the detail and what you get for the $$ MRC is the best. Some have pilot, co-pilot, and gunner figures. And I think some (if not all) versions of the MRC kits come with all the weapons to make all the other versions no matter what version is on the box art, just the decals and whether or not figures are included differ.
