Yesterday, we had the first competition of the friendly unofficial winter league with 6 pilots. We arrived around 11am, and flew until 2pm. The wind was about 5 m/s at the pilot point which is not at the edge. We mostly flew unballasted, and had to work hard on the trajectory to keep the speed and energy in turn. Very interresting and challenging. We managed to do 9 rounds. Then decided to switch to free flight before the wind dies slowly.
