Attitude hold by flybar loop results


Well, flybar loops didn't track attitude very well. The software flybar loop doesn't have enough force to overcome attitude changes. Could swap in bigger constants during autopilot mode, but that road probably includes monster oscillations. All roads lead to a cyclic neural network or less flybar stabilization.

Went back to full autopilot. Came to the conclusion that part of our problem is altitude oscillation. The neural network may also forget its training & relearn every 25 seconds. A few more PID tweeks and she's roughly where the Corona was.

It definitely looks like the Sirf III binary conversion is less precise than the NMEA output.
