Today I went windsurfing on the Maasvlakte with the Staaker drone. It performed really well. The wind speed was 22 knots. Sail size 4.7 with a 78 liter. The return to home option was set in at 38% battery level. The drone took of from a 2-3 meter wide paved cycle pad way in the dunes. When Return to home was set in, it landed nicely back on this cycle pad.
