Would like to get flight stabilization happening so it’s easier to fly FPV with the head tracker initially. At least if I balls it up I can throttle off, let go of the sticks and it will have some chance of landing flat. Would also be able to see compass headings, altitude and battery on screen through the OSD.
Think I’ll start here first and see if it works with that F3 board.
Some others to look at:

Ardupilot
Betaflight
MWPTools for navigation to mix with the flight controller. That or the INAV software.
