I have TM Warthog joystick and throttle. I have Logitech Rudder pedals. I am using 11.26 on my MacBook Pro. Most aircraft fly very cleanly. But some built-in aircraft have control surface problems on initialization. For example, the SR71, F4, Stinson, Cirrus, and perhaps others all initialize with their elevator hard down and the ailerons hard right. But other planes like all of the Cessnas, and King Air initialize just fine. I have tried calibrating several times and the axis are centered. The planes that have incorrect surfaces are impossible to fly.
