Ok here is the problem, in Aces High I can not get the plane to stay on auto-level or auto-angle for more than a few seconds and the planes seem to control horribly always unstable. I fly Warbirds a lot and do not have any problems close to this.
When I check my joystick it shows it jittering (spiking) in the analyze box. I have increased the damping and recalibrated numerous times to no avail. I am using CH Product Pro Peddles and F-16 Fighter Stick. The Fighter Stick is brand new out of the box. I just replaced my Thrustmaster F-16 FLCS, which had been demonstrating the same problems. The FLCS has on broken button and is 6 years old (tear in eye, love that stick).
