What a day.... Tryint to fathom out the switches, but the supplied instructions dont match the switches supplied.. After building a 'test bed' I spent most of the day experimenting. Eventually, the americans got out of bed so I was able to talk to someone! Eventually managed to sort it out... For some light relief, I installed the AOA again onto the modified avionics cover. New slip ball arrived, so now installed where I wanted it to go. really pleased with the outcome!
