I am building a .20 to .25 size FA18 pusher plane. I am to the point where I need to determine the general location of the installed equiptment. I will try to position as much of the equiptment forward of the the CG as I am able so as to offset the weight of the engine at the rear of the aircraft. The question that I have is with finding the Mean Aerodynamic Chord. I can find the MAC for the wing with no trouble but how should I consider the fuseloge fairings that blend into the wings on the sides of the fuse? They are equil to about 10-15% of the total wing area I think. I do not think I can just ignore then when locating the the CG for this aircraft but I have no idea how to figure them into the calculation of the MAC.

Any suggestion would be appreciated.

Thanks Ted
