slow, tedious progress to configuring the avionics to tak to each other... had to rxtende the OAT probe cable to reach the panel from the wing, still on its ce=radle. Then had to add a 'ground' between the wing and the fuselage. Added the GSA28 adaptor that makes it work when the servo is disconnected...
ended up checking the entire can bus and fixing a few problems.. all working in the end, but took ages....
