Just upgraded to the new style controller with the camera tilt wheel. This controller has been modified to add a new switch for slow yaw control. It also has the lever installed in the rear of the controller for camera tilt control. This tilt lever will only work properly if you haven't updated to the latest version of the Zen IMU software (needs version 188.8.131.52 not 184.108.40.206). Any offers will be considered. Thanks!
