i know it still early for me to learning about this,because of my passion on it i keep doing this, my preparation before entering flying school....thanks to my friend....
first thing i read was the theory of flight
-4 principles:Lift,drag,thrust and weight
-angle of attack: angle between the airfoil and the airflow
- Best Lift/Drag ratio : the greatest amount of lift for the least drag amount.Occursat 3 1/2 - 4
-factor affecting lift
+angle of atack
there are many more,after this i will try to elaborate more
