What are people doing about the fact they (maY) have two flap servos, each with a potentiometer, and just one set of pins in the Dynon unit? I guess all you can do it choose one, and if there's a failure you need to spot it by looking out the window... Or is there some other solution which I haven't considered?

Two flap servos would be very uncommon, and likely dangerous. If one servo failed you'd get asymmetrical flap deployment which rapidly leads to an uncontrollable airplane.
Most sensors on the aircraft are not redundant- oil pressure, fuel levels, switches to tell you your gear is down and locked. Flaps are no different.
Can you explain your situation some more so we can come up with a creative solution?

I understand it's actually controllable with aileron, in the event. I know a guy who had one side fail to extend due to mechanical failure of the linkage. He just continued landing with one flap down and opposite aileron.
I am looking at installing two separate linear servos, each with the same power supply and synchronised limit switches, and I am considering using the flap position indication feature of the Dynon D120 to indicate the position of the synced servos. I was wondering whether my only option is to connect just one of the two potentiometers to the D120?
The safety mechanism is both share a common power supply CB, which is specifically sized to trip if either one of the servo motors stalls, preventing either servo from travelling from that stalled position because they lose power together.

In that case, you have three options- monitor one of them, get the average of the two, or get the max of the two. Let us know which one sounds best and we can help more.
Thanks - the average sounds like the best. Can this be done easily?In that case, you have three options- monitor one of them, get the average of the two, or get the max of the two. Let us know which one sounds best and we can help more.
