That probably precludes most electrically operated flaps. Maybe this is one reason why the 2 place Grummans have such small flaps that don't offer much drag (or lift). To answer Jamey's question I would be surprised if a Cessan 150 can climb with it's big flaps fully lowered. If so, it's not much and probably won't meet the FAR 23 requirements, but then it was not certified under part 23. Also, there are a lot of planes that won't climb at higher density altitudes with the flaps lowered.

She spun it into the ground from about 300 feet. Maybe a plane CAN climb with full flaps. But, WHY?
