1.Provided, that the surface area is the same and the distance from CG to the vertical stab MAC same: Is the effectivness of outboard placed vertical stabs on the flying wing same, worse or better than one single stab placed in the midline ?

2. If the material for the stabs is the coroplast, and the material is placed in such way that the flutes are parallel(horizontal) with flight - does one piece actually serve as two surfaces, because it has double surface joined by the flutes ? (Coroplast is hollow double walled polypropylene corrugated plastic - like cardboard paper).

Thanks for help
