Both, my follow up post to this mentioned that i checked Macross Manual, but have no idea where they got their "over 41 meters" for the length
I mention in the post that i have no definitive #'s, just doing kind of a fun exercise in trying to figure it out.
When i made the pattern for the 1/72nd i used the 1/144 Yellow Sub kit as reference. I wound up with barrels to butt measurement of just over 22 inches. If you take the Macross Manual measurement of 41 meters give or take then 1/72nd should actually be just over 22 inches.
I think I measured the Hi Metal at like 15.5 inches with those barrels, so really like 1/104 if your getting super technical by what I figured,
Again, just a fun thought exercise more than anything else. The official numbers and the line art don't seem to line up all that precisely anyway.
Are you using the 1/72 model for dimension references, or the original specs from the line art? I wouldn't use a different model as a reference for the dimensions of a fictitious machine... that 1/72 model might be off to begin with
Oh, i just looked back at Macross Manual, and it says over 41 Meters long. So in 1/72nd it would be about 22.4 inches long, which my kit is from the barrel to the back of the body. The Hi Metal is 15.5 so it looks like its just about 1/104 scale if you want to get very technical and believe the Macross Manual at all.
