It's been a long time since I was here, but I wanted to clarify my comment regarding the loss of altitude when banking. Basically, you will lose lift when you bank, and the plane will start to descend. I have no problem with that. However, when the plane's nose drops, it will slowly start to pick up speed. This will increase the lift, and so the plane's nose should start to rise again. This (for example) works perfectly with the "other 737", so I would have assumed similar behaviour from the CS plane. By the way, I am talking about manual hand flying here. Hopefully, version 1.1 will have flight model updates to correct this.

With all aircraft, when I manually fly them and make a turn, I have to physically pull back on the yoke to raise the nose or it will drop gain speed, but lose altitude. This applies to aircraft. I always thought that is normal for aerodynamics.

Hopefully the 1.1 update isn't too far off. :)
