  The Coriolis Effect . . . .

    Some of you guys covered the following in various ways.

    There is drag due to lift because the lift vector ( force ) is not perpendicular to the flight direction. Drag is a function of lift and that component of the lift vector in the flight direction is called induced drag.

    Up, and down, both ailerons produce drag, but in unequal amounts if the wing is in lift mode. The difference in drag for pattern airplanes is small because of low wingloading ( low AOA ).

    The symmetrical airfoil plays a role in keeping the drag differential low because, to generate equal lift , upright to inverted, requires a different AOA for the non-symmetrical section.

    What did I forget?        Nat
