I have the Quality Fiberglass C-130 kit, and am very satisfied with it. Fiberglass fuse, foam sheeted wings & horiz. stab, 102" wingspan. I really love that CG paint scheme, but, being ex-Air Force, had to go with an AC-130 Spectre scheme. Check out the C-130 thread on the Twin/multi forum. Some are building from plans, some have the JHH kit, and others have the Quality Fiberglass kit.

A former student of mine just rotated back from Kodiak to Elizabeth City, NC about a year ago. He is a Herk crew member. (don't know exactly in what capacity). Name is Andy Miller. Don't guess you knew him, did you?
Good luck on your plane. (both of them)
