Nose, wing leading edges, anything that comes into contact with the air first is made as smooth and flawless as possible. The areas behind these parts of the aircraft are not considered as critical. Because of this, they feel there is not much purpose to spending the time or money to make these surfaces smooth. The Western countries do not follow this same train of thought and make the entire aircraft as smooth as possible. Weight Weight is the opposite of lift.
Weight is the effect of the gravitational pull of the earth on the aircraft.
We can always add more thrust, or create a more efficient wing, or even reduce drag as far as possible, but we can do nothing to counteract gravity. Now that you have a basic understanding of what actually holds your aircraft in the air, we can start learning Basic Fighter Maneuvers. I am sure you have figured out by now that holes in your wing reduce lift and increase drag. So lets learn how to avoid getting hit while making sure you cause some flight dynamics problems for your opponent.
