I have been having an issue while using the Mimic in gamepad mode. It happens in both fixed mount (inverted) and handheld setups. While using pan and tilt, the Movi displays no roll issues. If the shoulder keys on the remote are touched at all, the roll will begin to shake, the Mimic has to be cycled through "Kill" to correct. Occasionally it will have the issue on it's own while in this mode but very rare. Has anyone else had this issue?
