Hello, Currently , I am working in VTOL system based in standard airframe. I dont touch any part of the code.

And recently I discovered a “bug” and I would like to confirm with you , that it is a bug and not a configuration problem.

When I changed from MC to FW , I lost the control of the surface control and motor. In the log file, I could see that vtol\_att stop to publish the message, but the commander and other nodes work correctly.

[Flight Review - VTOL Standard](https://review.px4.io/plot_app?log=5a68fe83-3e18-4578-86fe-4b4ff0314811)

The rest of the components recognize the FW mode so I couldn’t disarm the vehicle.

The transition was tested in ground with 0 arspd speed and without propellers. The idea was to verify that all the process was okay before to go out.

Kind regards
