Hi Group
Will someone please explain why negative flaps supposedly
provides better aileron control. I know conventional wisdom
says that it does but WHY?

The flap/aileron interconnect has a lot to do with it.
With the help of another person;
Put the flaps in full negative then measure the max deflection of the
aileron (full up to full down).
Then put the flaps in full positive and again measure the max aileron
deflection.

With many sailplanes you will find that with negative flaps the interconnect
allows a greater range of aileron deflection.
