ok, if you like to harrier then use a plane with a square wing or diferencial airfoil on wingtips (like funtana thicker airfoil on tip), with a sharper LE than rounded; if you fly KE and like slow rolls and stuff like that you need a plane with lots of lateral area (more=better), if you like a violent tumbler and flat spiner then go for a short tail or go for a long tail (pattern like) for slow and straight 3D, AND the bigger plane for your engine NOT the bigger engine for the plane, It have to pull out of hover secure it is a nonsense to rocket out with a monster engine
