What sim? We'll want to avoid that one.

I've used flight games where the rudder did funny things, like cause yaw without changing flight path, etc. (I think that was one of the WWII interactive games, like Air Warriors or one of the others.)

The rudder on our models causes the plane to yaw (turn left or right) and change direction. If the wing has dihedral, some roll will accompany rudder use. If your simulator doesn't cause the same, you won't be able to learn to use the rudder with that sim.

Good luck,
