You'd want head temperature and oil temperature feedback to do it right. Oil temp for initial placement and head temperature to temporarily open further for more cooling.

Agreed. And technically, it would be a step motor. Also, you could do away with the thermistor and just hook up to the oil temp sender. So the controller might be nothing more complicated than an oil temperature gauge that switches the step motor. That's the ugly way to do it. Maybe there's a cleaner way.

Seems like a thermistor and a servo could substitute for the NLA thermostat for aircooled engines. The servo could be mounted up on the flaps, in the cool part of the engine compartment, with only the thermistor down where it's hot. It shouldn't take too much thought to make sure that if it fails, it fails in the flaps open position. Or buzzes a warning! So, tell me why this wouldn't work.
