Have you read this page Hexa config ? Also you should be able to set X or + in the mission planner after loading your Hexa firmware and going to the last tab of the Configuration/Set-up menu.
In APM Planner 1.1.63 the Configuration/Set-up brings up a window called "Setup" with options down the left side
Am I missing something?
Thanks in advance.
It's in the Firmware tab in Mission Planner.
Good luck to you!
I am not seeing that option??
