I know, I like that moment from the movie too, but if you want to make some serious research then you can clearly see where the FX crew used this or that model...and then you must choose which one of them do you thrust (in shape or scale).
Funny thing
UD-4L Dropship with APC will be full of compromises.
..
My angle of view on the whole project is
real life Scale and decreasing it into 1:24. So the primary pattern for me from the movie is 1:1 scale props and instalations....everything where you can clearly see people around the studio instalations.....
I´m curious which problem or challenge will be next...
