Over a year ago I printed a Huey with my 3d resin printer. You can read more about this here. Alas I didn’t have any door gunners. Now I got a few door gunners from Empress miniatures, sculpted by Paul Hicks.
And both in the 1/50 printed Huey. I think they work really nice in an 1/50 ship but also in a 1/48 one. Have a look here
