I've noticed a lot of aircraft are designed to use washout at the tips
to control stall behaviour. The idea as it was explained was that they
wanted the inboard part of the wing to stall before the outboard part
so aileron authority could be maintained a little longer.

I've also seen mention of stall strips being installed inboard to try
to affect the same thing.

Constant cord (Hershey Bar) wings need no twist, or stall strips, as they
stall naturally on the inboard section, with the tips remaining flying to
the end. They are not as efficient at high speeds as elliptical or
tapered
wings, but that is seldom the mission of planes that have constant cord
wings.

This may be a good generalization, but I can think of at least two
exceptions. The Grumman AA-1 and the Piper Tomahawk. I've never paid much
attention to the Grumman AA-5, but I wouldn't be surprised to see 'em there
either.
