Now that I am trying to learn the in's and outs of trimming - I have a question. The turn and bank indicator has a needle and a ball. The needle responds with rudder input and the ball responds with rudder trim input. By centering the ball with rudder trim what exactly is happening with the plane? Since many planes don't seem to have aileron trim I've added elevator and rudder trim to the X-52 and am trying to learn.
Also - some AC seem VERY hard to level out. I understand that planes have optimum cruising speeds where they fly level more easily - are these listed anywhere for the planes in the game?

The ball is simply a ball in a curved glass tube. When your plane is pointed in the same direction as it's flying, the ball sits in the bottom of the curve (centered), but when it's pointed bit to one side the ball will roll to the other side. The tube is filled with fluid (alcohol or light oil) to make the ball settle quickly.

The needle indicates rate of turn or bank angle, I don't recall which.

There are a couple of aircraft that replace the ball with a second needle, among them some of the British aircraft.
