Developed the system a bit further. Now it's starting to resemble jet physics a bit better imho. What do you think: <obsolete link removed> It's a rather complex system. Basically I read joystick axis values from a joystick mocap server app into an expression. Then I do some filtering and scaling to the values and assign the values to the plane rotation and whatnot. The plane is a rigid body object an is affected by gravity, lift force and thrust, which is joystick controlled too. As a visual goodie the ailerons, rudders, thrust blades and elevators move according to the joystick movements too...
