High tech wheel pants and old fashion wing.


In fact the wing is much more high tech than the planks that have historically
been strapped onto various Cessnas and Pipers
It is tapered and has washout in the tips such that they are not providing lift
(and thus drag) at cruising speeds. You thus find that their cruising speed is
higher for the same horsepower engines than most convential (for that read spam
can american) aircraft.

Of course, they are still producing drag; after all, they are in the
airstream. What they are not doing, according to your description, is
any useful!

More likely, the wing tips are producing lift, though the designer might
have selected the twist to optimize the lift distribution at cruising
speed; that is, an elliptical distribution. Or, as Ian suggests, to
improve the handling qualities.
