I am using the Ray Allen POS12 flap position sensor on the flap tube on our F1 Rocket. Some people are saying that we do not need the supplied micro-switch that came with the AOA installation kit. Can someone explain how to use the POS12 to tell the AFS 4500 that the flaps are past 1/3 so I don't need to install the micro-switch. Maybe this is not possible??? Thanks, Tony
