Keeps the tips out of the weeds while improving lateral stability :-)

We use DR400 Robins as tow planes. Like many (all?) Jodel designs, they
have flat inner wing panels and dihedralled outers. There is also a lot
of wash-out on the tip panels (shown in the side view photo on the link).
I'm told that at cruising speed the tips intentionally contribute zero
lift while minimising tip vortex drag, making them very efficient at the
design cruise speed. They're good tugs too.

We used to have a Rallye and a 235 hp Pawnee, both now replaced with a
pair of Robins.
