Works very well for me and is individually calibrated (calibratable?) to any installation. A pivoted pointer in the cockhouse connected to the appropriate point on the flap actuator lever via a flexible push-pull cable similar to a bicycle brake cable - the kind that slides inside a flexible tube or housing is simple, foolproof and easy to build. A case of simple being better than hi-tech - and works even when the power fails or before you turn on the master. Be glad to show it to anyone interested at the Redmond bash this September. I happened to use a length of music wire inside of a Teflon tube but you get the idea. This push rod not only gives me a position indicator, it also provides the mechanical feedback to the flap position selector servo. KISS is the only way to go.
