It's incredible you feel not enough confident and knowledgeable, to attempt any plane, military or not... but it's better for us (for me)
Well first and foremost, I didn't find good schematic sources for the KC-10, and on top of that I'm much more 'knowledgeable' on civilian planes than military ones. Therfore, as you said, I would not to have all the fun for myself
With your permission, I will process the C-118/R6D
Sure, my only plans for prop planes right now involves the DC-7, and maybe a refinement of your C-54 into the civilian DC-4s. I'll be back to jetliners and SB warships after that
