Plane on bench no disarm

Hi.

I try to commission my little AR Wing with an Omnibus F4 pro flight controller. Currently I have no RC connected to it.

When I power on the system, it directly arms and I can not disam it. When I do I get an error and on the console, I find the following:
INFO MissionPlanner.MAVLinkInterface - doCommand cmd COMPONENT_ARM_DISARM 0 0 0 0 0 0 0
INFO MissionPlanner.MAVLinkInterface - set giveComport Base Thread current False new True
INFO MissionPlanner.MAVLinkInterface - doCommand cmd resp COMPONENT_ARM_DISARM - FAILED
INFO MissionPlanner.MAVLinkInterface - set giveComport Thread Pool Worker current True new False

INFO MissionPlanner.MAVLinkInterface - doCommand cmd resp COMPONENT_ARM_DISARM - FAILED

Any Ideas, why I can not disarm it?

On the little console in mission planner, I see:

Fixed it … Did a parameter reset :wink:
