This thread is interesting, I'm gathering info for a sctratchbuild project, a non-transformable VF-4G (Fighter mode)in 1/48... I think I'll have to "invent" some parts, like the landing gear wells and some cockpit interior... I read somewhere that the VF-4 screen was retrofitted to VF-1, creating the "Block 6"... I'll assume that this screen wasn't the only thing retrofitted, but main controls and ejection seat as well... Let's see what happens.
