The first flight (50) was for testing Will's heading tracker with Thor which consisted of 180 degree turns, and four 90 degree turns to make a rectangular pattern. This flight was completely closed-loop. Initially it seemed as though the controller was performing poorly. Upon inspection of the data, the signal seemed to be tracking the command fairly well. However, the plane was not given enough time to settle with each turn, so another flight was necessary which allowed more time for settling. The software used for this flight was branches/WayPointTrack/Software/FlightCode rev 856. Flight 50 was dedicated to testing the performance of Will's heading tracking controller.
