We are not sure how to detect the very earliest initial wing tip movement
or drive the small trim type motor and would appreciate some thoughts or
site recommendations to investigate.

The idea of a ball bearing in a tube is not even close. Ever hear of the
graveyard spiral? It is what killed Kennedy. (not the president) In
such
a spiral, you experience several 360 degree turns, diving steeply enough
that vertical descent rates of 10,000 feet per minute (if the plane holds
together) are possible. Still, the ball in the tube would stay right in
the
middle. One G all the way.

You need a gyroscope, or an electronic equivalent. Some have played using
very sensitive GPS antennae in the wingtips.

Best advice? Trim the plane, stay awake and fly it, or BUY an autopilot,
or
wing leveler. Or google wing leveler.


Automotive world is using electronic stability-control (ESC) systems with
documented success. The article says the system used a decade ago wasn't
very good, but they've come a long way since then.

I'm guessing some variant of this is what you'll eventually cobble together
in your garage.
