I've got a couple of these and in addition to what Gino mentioned the interior soundproofing looks more like diamond shaped tiles than quilted material. If you are going to use the M6 system with flex M-60's instead of the M21 system with miniguns, you'll want to replace the rather featureless weapons that come with the kit. Another issue is that the ammunition chutes are made of a rubber or soft plastic that is not compatible with the rest of the kit. They melt into whatever they are packaged with. In one kit it was a rotor blade, which is probably repairable. In another one, they melted through the pieces for one of the seven shot rocket launchers. Fortunately, there was an extra sprue with those parts thrown in the box.
Other than that, it's not bad and the only large scale B out there, unless you get the MRC/Acad UH-1C and the Cobra Company UH-1B conversion.
