What the title says. If I start with default engines off configured on x-plane (cold & dark) and last plane was CRJ-200 (consequently starting X-Plane inside this aircraft), then I change to whatever other aircraft, roll, yaw and pitch deflection surfaces don't move (they DO show as working on the joystick options). The workaround is starting the CRJ-200's hydraulics, or re-open the CRJ with default engines on, then changing aircraft.
