Hello, I just want to use AC45 for flight a little racer without GPS and compass on stab mode and althold only.
I make a first attemp flight desactivating completly compass and gps in EK3 src params and all seems working well.
But I experienced and EK3 failsafe.
What parameter I need to adjust to avoid that?
or for this setup you advice to use ek2 or ahrs?
Please let me know.
