OK, that sounds like a problem. > I think moving a control surface, like for example the rudder, from full left > deflection to rull right deflection in an instant is unrealistic.

In real life, in a small airplane, if I decide to stomp on the rudder pedal, the rudder is going to move real fast. The realistic time scale is not long compared to 1/30th of a second i.e. the inverse frame rate. That is to say, any filter with a realistic timescale wouldn't solve the problem. The problem (as usual) lies with the nut behind the steering wheel. If you don't want the rudder to move real fast, don't command the rudder to move real fast. -- Specifically, if the problem is a noisy joystick, fix the joystick somehow; don't mess up the FDM. -- If "5" is doing the wrong thing, make "5" do the right thing. ------------------------------------------------------------------------- SF.Net email is sponsored by: The Future of Linux Business White Paper from Novell.
