Correct. I flew a turbo 206 with the Robertson kit. It would droop the
ailerons 10 degrees with the first 15 degrees of flap. We regularly operated
in and out of a 500 foot strip in Southern Oregon for 14 years.

Some of DeHavilland Canada's designs have/had them; I know the Twin Otter
does - it's interesting watching them land in the harbour here with the
entire trailing edge of the wing sagging! The Twin Otter is mechanical,
of
course.

These are called drooping ailerons and were used (in a reportedly
unreliable
design prone to asymmetric deployment caused by freezing of cable
actuating
system) on the Noorduyn Norseman. Credit is usually given to Dick
Hiscocks
and Fred Buller for the excellent design of the mechanical (reliable rod
actuated) drooping ailerons used on the DHC stol series that began with
the
DHC-2 Beaver and grew into the single (and later twin) Otter as well as
the
larger Buffalo and Caribou aircraft. These aircraft are legendary for
their
stol capabilities due mainly to the use of drooped ailerons (and big
powerplants).

I believe that the Robertson stol kits for the C-337 and others also
feature
modifications that cause the ailerons to droop with the application of
flaps.
