Hello. I am currently building a VTOL tilt-wing aircraft using Pixhawk4, Mission Planner, and ArduPilot. When flying in Q-stabilize mode on Mission Planner, I cannot control yaw. Is there a solution for this issue? As soon as the aircraft takes off, it rotates counterclockwise, making one full turn every two seconds, and I cannot control the yaw with the controler. In Q-loiter mode, there is still some yawing, but it is less severe compared to Q-stabilize mode.
How far along the tuning process have you gone?

You haven’t given any details of your set up. Are you using tilt vectored yaw control? If so, have you tuned that?

You can also post the .bin log file of the test flight, that can give us some clues to help you. Without a .bin file it’s really difficult to help.
Thanks for your help sir, i will do it tomorrow. it’s my first time making Quadcopter, so i am not good at it
