>Let's talk about something else: the zero lift moment coefficient (cm0) is around cm0 =-0.017 and this is unstable.
This means you'll either have to add some washout (this can even be beneficial for performance in small amounts) or have to compensate slightly with the ailerons
Not that it's a bad profile, but keep this in mind

>What do you guys feel about adding center fuselage to hold battery, esc, amp, motor, landing gear etc to the build?
Try to aim for something in the lines of a blended wing body, or at least something with an airfoil shape to it for a better lift distribution
Otherwise it sort of defeats the purpose of a flying wing, which is to eliminate the need for fusulage after all
I guess this is a bit more difficult to cut out of foam, but i honestly have never tried it

>How do i deside how big of control surfaces should i cut?
No idea senpai. I made a glider from balsa once for a project. Like i said i know some theory but that's basically it.
