wing levelers

Ah. You might consider pursuing developing a "rate damper". This would be
much simpler than trying to control attitude, as it would only require
sensing of rate. This would not act as a wing leveler (well, not exactly,
but it might provide some attitude stabilization without correcting for
drift), but it would respond to bumps. You'd still fly attitude, but the
damper would handle the transients due to turbulence, etc.

Being a flight controls engineer, I won't advise you further on this project
(not willing to assume any liability on a project I don't control), but I
will provide the following advice:
(1) Incorporating such capabilities on an aircraft is LOADED with very
serious potential hazards, all of which can be mitigated by a very careful
and conservative system buildup. These include:
- PIO susceptibility
- runaway servos that can make it difficult/impossible for the pilot to
fly the airplane
- high transient electrical loads
- high mechanical loads on your airplane
(2) Set things up so that you can always turn it off quickly and revert to a
normal airplane (i.e. no mechanical load on flight controls from an
unpowered servo. Set it up so you can always mechanically trim out what you
get from a stuck, hard-over servo.
(3) Instrument the system thoroughly during development and test so that you
know how hard you're working your airplane.

Check with some R/C modelers to get the idea on how to set something like
this up.

Trying to make summer flying in chop somewhat easier. We didn't plan on
turning over controls to the device and would still keep a light grip on
the
stick; just wouldn't have to constantly play the stick.
