I saw somewhere on a recent posting some discussion of forces needed to deploy flaps. I have HDPE tape on the flap skins where they rub the wing top skin, and there are clear witness marks showing where the flaps are during flight. Of course, on the ground with no loading, they are down a bit further than these marks indicate. What is amazing is how little force it takes at the trailing edge of the flap to "raise" them to their highest flight position. I'd estimate it might be 15 pounds per flap. I'll try to measure it with a fish scale next time I'm at the hangar.
Of course, some brave or crazy guy who has manual flaps could get some altitude, use a fish scale, and post the results! I can't imagine how we can build and fly these planes without this important data!![Eek! :eek: :eek:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
