Why overcomplicate things. This is just too easy an application with a
BasicX board and an accerleometer.

Couple this with a cheap GPS, and big servos modelled after the ones used in
RC aircraft (the BasicX computer is designed to drive them directly), and a
complete autopilot is an easy design project.

I;ve been playing with this for a while, but I'll admit i've spent more time
thinking than soldering.

Anybody seriously interested in teaming up?

Before anyone rushes into anything take if from someone who has worked
AFCS, stab aug and the like. I have been in rotor and fixed wing
aircraft when the systems have gone nuts during inflight ops checks.
Fortunately the systems could easily be overpowered manually and
disconnected either by a button on the stick grip.

In any event all the systems had a ton of engineering and flight testing
before being accepted for service.

On the other hand some of the nutso systems can be quite amusing in
hindsight. I had an H-3s aug system problem I couldn't duplicate on the
ground. I requested a flight. They sent me a pilot who had a habit of
placing his coffee cup on the floorboard near his foot. We hovered, he
engaged system which promptly went crazy. I'm standing in the back
looking over the FE's shoulder, holding on for dear life and collecting
dings and dents in my helmet. The pilot calmly reached down, picked up
his cup of coffee, took a swig, put it down and then disengaged. After
we disembarked I asked him why he had done that. He said something about
enjoying the ride. That was about 20 years ago. I still think it was a
bit funny
