A new IMU was installed, and internal filter settings were adjusted. The weather was calm and sunny. The very first flight used the data logger with the 10 extra signals added. It was not able to log the data correctly, so the old data logger was then used. There was also a flight in which the flight computer stopped working correctly after 35 seconds of running. Everything worked smoothly after a second try. Besides these two setbacks, all flight ops ran smoothly. The first flight (53) consisted of multiple touch and goes, staying in the landing pattern. The internal IMU filter was using default bandwidth settings. The EKF filtered flight data was not accurate. Software used was trunk/Software/FlightCode rev 866 *NOTE: In IMU_iSensor.c, the " Send command" lines 68:70 were commented out in order to use default filter settings. Flight 53 tested the newly installed IMU using default internal digital filter settings. Rx data: A017, L018, F001, H000 Thor Flight 53en-USThor FlightACRCAnokaIMUEKFFilterDataset
