Well, flight models have the four basic forces of drag, lift, weight (from gravity), and thrust. That is as basic as it gets. Drag comes from air friction (aircraft speed and design is a factor), lift comes from the aerodynamics of the wings (surface area of the wings is a factor here), weight is fairly self explanatory, and thrust is from the engine power (unless it''s a glider, then there''s no true thrust and you get gravity involved). If you apply the basic Newtonian physics equations (based around F=ma), and maybe get your hands on some of the basic flight model equations for things such as lift, you may be able to produce a very simplistic flight model. Since you''re interested in this, I would suggest that you do start off with a very simple, working model and add more complex variables as you go along.

I read a book called "MECHANICS OF FLIGHT" by A.C. Kermode, 10th edition. I could probably write a flightsim using only this book, it''s that good. Good luck
