And here are the yet unmodified "Franz und Emil" for my CI. Both will be getting brain surgery since both will be wearing the typical German crested "fliegerhelm." (BTW, I'm informed by a very knowledgeable source that these helmets were made of treated linen, not leather.) I picked these two head sculpts because to me they seemed to have the right personalities. The pilot seems older and more experienced. The observer looks like a scared young kid, which is probably about right.
In terms of positioning, I have a photo that shows the observer/gunner almost complete within the turret with the MG pointed upwards. That's great for me since it means less dummy and therefore less weight. (I have the rotating turret slaved to the rudder servo such that when the rudder moves right the gunner swings left.) I might have the pilot leaning to either the left or right since he wouldn't have been able to see anything with that honking great Benz BzIII inline in front of him.
The "great coats" will also be severely cut down.
