Thanks for the info on clear resin, daremo. Guess I won't be going that way, then.
Anyhoo, since I had the high line off, I decided to open up the fuselage again and move the firewall and bench forward a couple of centimeters, to make getting gunners in there a little easier. It was marginally effective, and I still think female figures are gonna be the only ones small enough to work out.
The end result certainly wasn't worth the position light I lost to the carpet gremlins. At least now I don't have an excuse to not start harvesting bits off the Super Cobra. The AN/ALQ-144 off of the tail rotor looks good up on the Huey's dog house, even if it is an anachronism.
