Klaus,
Here's some shots I took during deployment to K-1 back in 2003. An added bonus is that it shows the internal ammo bins and how we normally secure/route the feed chutes. As far as the overhead panels, 99% of the time you won't see much forward of the rear area since it's almost entirely covered by soundproofing/insulation. Some are black (NVG Mod) some are OD. There are a few clear plastic panels for quick inspection, but most of the wiring, etc. is covered. If you're modeling an HH-60G (Pavehawk) and want to be realistic, you'll probably want to do it with the soundproofing in place. Your call. If you do want to show the wiring and stuff without the soundproofing, let me know and I'll see if the maintenance boys will let me take some shots with the soundproofing removed. I might have to bring them a box of doughnuts though.
Here's one showing the Euro Green main rotor mast I had told you guys about earlier. We only have a couple birds with these. If you look through the gunner's window you can see the soundproofing.
Here's the one from K-1. Note that the ammo bins are "borrowed" from the 129th RQS out of Moffit, and that they both feed towards the front. Also note that we didn't/don't mount the FE or Gunner's seats, but instead just taped some cushioning to a gear storage box. This is for freedom of movement around the area and to increase space. Also note the "Oh Sh!t" button. This is part of the AN/APR39 system and allows anyone in the rear end that see's a missile threat to launch flares/chaff immediately. You can also see where we store the aircrew weapons (M-4's).
