Welcome to the club. I am making ZIS-5 and ZIS-6 trucks from scratch in 1/72 scale (these are going to be complete, faithful and terribly small replicas).

why the HELL would you make a 1/72 scale TRUCK???

Diorama elements?

anyway... whatever fans I use will each have to be mounted in a dual-ring gimbal setup, like so:

from what I can gather from the books, the fan rotor diameter is 100cm. so, at 1:10 it would be 10cm or @3"

THAT sets the baseline for the fan I need, and thus the electric motors, thence the batteries, etc...

I need HARD DIMENSIONS to begin designing around, y'dig?
