Long time Lockheed family, ex-employee, and fan.
I have had three 1/72nd scale C-130 model kits for a long time. My original intention was to kitbash an unusual stretched model of a C-130.
For several years, I have been trying to get some of the new composite propellers. No luck from all possible sources.
I finally managed to model an NP2000 in SketchUp. I can probably manage to translate it to another format, and then see how suitable it is to print (resolution, etc) & if it needs repairing, etc...
I need 4 or 8 of them made out of pretty much any material. They are about 2.25" actual size.
