Hi Tread!
I'm sure that someone here will post some pics or scan some images for you but you really need to get these two books for great info, pics and drawings!
1. The Squadron # 91 CH-47 Chinook in action ......it has some pics and drawings of the Guns a Go Go birds.
2. the Aerofax Minigraph # 27 Boeing Helicopters CH-47 Chinook by David Anderton and Jay Miller.....This is probably the BEST Chinook book out there, it is out of print but they show up on ebay often and you might find one in used book stores......most major cities have military or aviation book shops as well.
If I had a scanner I would scan the drawings of the wing assy for you.......scratch building thosr should not be that difficult.....but to do a proper CH-47 A set up as a GO GO....one would need to build the nose thumper, interior detail, ammo cans, feed system for the nose thumper, ramp and window guns.
PHEW!
Straighten up and fly right.....
