I think maybe it is connected to Cross coupling? When I had the Logitech joystick, you pretty much set the throttle 95% and left it there, you could do almost all the flying with the x y and z axis. I probably learned bad habits there...

Will have a look at your thread, thanks. Was going to ask if your Javelin name was anything to do with the Gloster Javelin, but seeing your location I would be surprised if you had even heard of them!
