Quadplane Ark Optiflow Issues

Hello everyone,

I’m currently building a quadplane and I’m interested in integrating the Ark Optiflow sensor into my platform.

Has anyone here used this sensor in a VTOL configuration?

I’ve encountered some confusion regarding the EKF source switching between Optiflow (OF) and GPS on the ground. When in OF mode, switching the EKF source triggers a switch to DCM active for the AHRS . I’d appreciate any insights into why this happens.

Additionally, if I’m flying in DCM within plane mode, how can I transition to OF for landing without the AHRS switching to DCM again in Q (copter) modes?

I am happy to send logs upon request related to the questions above.

Thank you in advance for your assistance!
