After upgrading the aircraft version (above 4.4.0), the parameters of mnt cannot be found

ArduPlane Plane 4.5

In the past, using firmware version 4.3, it was very convenient to open and debug mnt. Just set mnt1_type = 1 to enable it. But after upgrading to 4.4 and 4.5, the option to enable mnt cannot be found in the parameter table.

Ask and answer yourself

Well, I’ve figured out what’s going on since I use a MATEK F405 WING. Therefore, after version 4.4, due to insufficient flash, the gimbal part was deleted, so it cannot be found in the parameter table:)

you can use https://custom.ardupilot.org to select what features you want on your board. As the number of features we have increases it has been difficult to make the right choice for everyone

I tried compiling, deleting a Q section and adding a gimbal. Obviously the compilation failed。

note that you can de-select the Xactti driver to work around the issue:
