RE: Zero scale?
Yes and keep in mind, back then, most jap pilots were small, so a regular pilot in 1/8th scale will look big in the cockpit, I had the 120 size one but sold it before finishing it, I had pictures on how to do scale gear doors but lost them all due to giving the old PC to the ex girlfriend when I split with her. The pic's are here on RCU with a bunch of scale documentation on the zero, color schemes and different outfittings of the plane.
I think it was "GSP Zero" for a thread.
