The 601XL I'm building is designed with a simple ON(mom)-off-On(mom)
flap switch. I was wondering if anyone makes a gizmo that would go into
the circuit that would allow a single momentary push position the flaps
into 10º then a second would move it to 20º and so on? Obviously the
same going the other way.

I could live with a gizmo that just ran applied the power to the flap
motor for X number of seconds either down or up for each push as long as
X is something I could set.


Have you looked at something like this:

It's programmable to 3 preset locations, but you can slew the actuator
to any position by pressing the center button and either left or right
button simultaneously. I found a spec sheet at:

It must be used with a linear actuator with a feedback potentiometer
like this:

Or, you could mount an external feedback pot on your existing flap
actuator.

I couldn't find where these particular automotive linear actuators
(used in "...power-operated hoods, trunks, tonneau covers, or any
other heavy-duty application") have been used in aircraft, but I'm
thinking of installing one in my RV-4.
