I ran this question through here about a year ago. Most everyone mentioned that wing area includes the area through the fuselage. ..... except for rubber powered A/C.

Have yet another question regarding this again. I may ahve come upon yet another exception.

I have a A/C design from Russia. I have tried this way and that to make the stated wing area match what is determined via Autocad. I get real close iffn' I subtract out the area within the fuselage, and measure the area just underneath the wing-dihedral included. This hits the same for main wing and for Hoz-stab areas. The rear Hoz-stab has a healthy amount of dihedral.

This A/C is an F.A.I. competition design. Is it a Russian routine to indicate wing area as per projection or is it some competition ruling?
