right wing keeps dipping down

[Megatherion]

I would have no problem with this if the torque and gyro realism effects were turned on, but with all realism effects turned off, the plane should be able to fly level with hands off. I unplugged all my joysticks and flew with the keyboard (yuck!) and the problem is still there. Does everyone have this problem or is it just a few of us, can anyone fly hands off straight and level(applying trim as needed) with the spitfire or hurricane?
