The plane was started with hand launch with accelerometer triggered motor start in auto mode. Due to the high wind, the launch was without problems. The motor starts with a delay of maybe 0.5s. The plane followed a flight plan of rectangular shape. We later increased the parameter “TRIM_THROTTLE” from 0.33 to 0.45 and then 0.55 as our impression during flight was that the plane had problems during the turns when the wind direction changed for the plane. During turns the plane often lost altitude. Apart from the altitude problems the plane followed the given pattern. The first rounds were at 50m and the following rounds at 30m altitude.

The last waypoint was landing. After that waypoint was active, the plane lost altitude and then probably stalled and crashed near the street.
