My project is a 5-rotor VTOL V-tail plane. I am using the Mateksys F405-VTOL flight controller and flashing it with the MatekF405-TE target using arduplane_with_bl.hex. However, some parameters are missing, and I can’t find them. I am using Mission Planner V4.6.0-beta4."
That board has limited memory, it is normal that some features are missing.
You will need to disable some features to make space for other features, or get an FC with bigger memory.
look at custom.ardupilot.org to custumize the features you need.
