I have been driving myself nuts with the geometry of the front chisel section of the plane. I could get it to line up nearly but not quite, and couldn't work out why. I decided to give up as it was damn close, then taking a break then coming back to it I spotted something that really should have seen before.
You can clearly see on the full size buildup and the ice-floe landing model the front and side facets are totally flat, which was the assumption I was working from for my model, I now know why I couldn't make things line up.
The 1/12th hero has an error, possibly intentional, but probably not, where the slant angle of the window canopy facets are steeper than the nose sections as shown by overlaid lines in the pics below.
I think maybe what happened was, they cut out the windows from the resin/fiberglass shell, including the top window which leaves not much material there. This might have fractured or they cut the whole part off thinking they were going to have an opening canopy, then fixing it back in place the angle of the top of the canopy section changed so the front is lower. It's hard to make out but the canopy roof level drops to below horizontal
However on the other models, including the large reverse blue painted one the top of the canopy is flat to slightly rising back to front, and the side windows are deeper. You can see it in these shots.
It might not look that significant, but altering the model to match, when I draw a horizontal line from the top edge of the front facet to where it should be if the facets were flat, real size it is about 120mm difference, or 5mm at 1/24th scale.
So, the question is, which is correct, it does appear the big hero is the odd one out.
