Hello,
Today, I transited and flew my freeman 2100 VTOL in fixed-wing mode for more than about 5 seconds. Firstly, I transited it in the sea direction, and stopped it with multicopter mode, and I turned yaw at sea, and planned to test its roll and pitch axis control when I flew from the sea to the land (home position) direction. I observed that the airspeed was 12m/s, but the ground speed was 22m/s during this flight. I calibrated my airspeed sensor properly with Mission Planner, and there was no wind; the wind speed was about 1~2m/s as the sea was very calm. I would appreciate anyone’s opinion on this symptom.
When I transited from the sea to the land (home position), it was very fast and frightened me because the speed did not seem to decrease quickly, when I saw it in very long distance. There was a tall building near the landing site. Nonetheless, I changed to QHover mode very early, and its speed was stopped safely and smoothly, landing well in the designated spot. However, I suspect there may be an issue with the airspeed sensor. before take off, after calibration, I noticed the airspeed value was 1~2m/s, which is normal.
Here is the flight log (bin) file:
I use Pixhawk Cube Orange Plus.
Thank you for anyone’s assistance
