**How do you CALCULATE PORT LENGTHS of AEROPORTS?**

[swollen_cu 10+ year member]

I'm going to use precision soud ports on my box build, but I have a question on how to type in the

box volume calculator for the aeroports im using from them below. It asks for the Volume of box in cubic feet.

Is it asking for the volume of the box in general before displacement, or is it asking for the volume of the inner airspace after all displacements. It makes a big difference in cutting length. I just dont know which volume to use. Anyone know?

Thanks in advance...

This is the calculator from their ports...
