Question on airfoils

[Fra119]

So I've seen people hiding wings inside their ships using megavoxel (a voxel that extend over the 1x1x1 boundaries) for aesthetic reasons, as I want to preserve the look of my ship too I'd like to try this solution.

Now I'm wondering how many xs wings I might need to obtain x thrust, so by looking at the engine library i noticed that an XS wing has 1/4 of an S Wing thrust but ~1/5 of its mass, same for the M wing, the XS has 1/16 of its trust and ~1/27 of mass. 

Is it really that simple? Do I really need only 16 xs wings to obtain the same thrust as an M wing, and with less weight? Or am I missing sonething?

Thank you

Yeah, I don't know why they did that with airfoils, it is the opposite with engines and brakes which have better force to mass as you go larger.
