With the summer thermals upon us, and not being able to scratch my nose
without having my small homebuilt tossed off course got me to thinking
about how to build a low cost wing leveller.

A small servo tab mounted out on the aileron, controlled by a jumbo
sized R/C servo would probably work fine. If the tab was sized fairly
small, even if the servo went nuts, the pilot could easily overpower
it.

The servo would be controlled by a rate gyro that is also used in model
airplanes and helicopters to provide the stabilizing function.

The overall system would be controlled by a simple pulse-width
modulator using a 555 chip. A small amount of trim adjustment would be
provided.

Operation would be simple: turn on the system and adjust the pulse
width trim knob to get the wings level. Sit back and scratch your
nose, take a pee, eat a sandwich.

This simple system could be put together for under $300. Any thoughts
on how it might work?
