Are you saying that no type of flap adds lift? My other curiosity is, are you an Aviation Engineer?
Reason I ask is, any flap that increases wing surface area as it is extended ---should--- increase lift.
Your thoughts.[8D]

flaps don't add lift
they just reconfigure the airfoil
Try this: trim for a set cruising speed level flight (for the pilot-in-the plane- guys)
Now add flap - a little teesy bit- what happens?
the plane balloons?
Does it continue to climb?
Or does it gradually slow down.
Ad a littl more (still under 20 degrees)
what happens?
More of the same?
If the flaps added lift - the plane would continue to climb with NO power increase needed.
They do keep the fuselage at a low AOA-and the big wing and the little wing (I love that one) at low AOA
but the drag is always higher-always-
