Sitting around the hanger and discussing the possibility of somehow using
off-the-shelf electronic/computer components or gadgits for semi-automatic
wing leveling on lightly loaded, short wingspans.


As an example: One fellow pictured a rolling ball bearing inside a tube
somehow activating a magnetic switch which in turn pulses a dc linear
motor
to operate the aileron minutely.

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.


Hmmmm. No free (or even cheap) lunch, here.

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.
