After hunting for one, I cannot find a 1:400 model of the An-225 and thus have decided to scratchbuild one (or at least 5 for various reasons), so a couple of questions.

Most sources say the An-225 is based on the -124 with a few noticable differences:

- larger wing
- larger number of MLG arrangements
- lengthened fuselage

Does this mean cross section wise, the An-225 is technically the same fuselage as the -124 or does it differ in other ways?

If this is true, I can take a current -124 and lengthen it myself, along with replacing the wing and landing gear - sounds better than scratchbuilding the entire model (which I will do if necessary).

Does anyone have any good plans for both the -225 and the -124 I can use in this project?

Does anyone have any tips, tricks or comments that would come in handy?

Lastly, does anyone know of a 1:400 An-225 model that would save me the trouble
