My suggestion to you is go to library and see what you can find on aerodynamics. Now much of this likely will be way over you head (and mine) but some may be understandable, and you may even find info on models. There are many things that affect and pertain to an aircrafts performance. Such as center of lift. thrust line, airfoil, lateral area, C.G.,incidence, dihedral, aspect ratio, decaledge, power to weight ratio, etc.These are all common terms used in aircraft. Research can be rewarding and fun
