Arming control, how to change it, help needed

Hi all

A quick Mission Planer/Pixhawk question I hope

Where in mission planner do you change the control method for arming a Pixhawk

I have four of them and for some reason two arm low throttle Rudder left and two arm low throttle rudder right, so obviously I need them all to arm the same way, been through the setup pages but can’t for the life of me find it.

Thanks

Paul

Arming should be throttle down and right, if two are set up with arming down and left maybe you have your yaw (rudder) channel reversed on these.
