This could be a forum all it’s own. Particularly as a repository for collected wisdom on this topic. Still, I would be interested in hearing about (& seeing) folk’s camera set up, settings, filters & lenses, airframe & cockpit mounts, accessories. How many cameras & where. I find it disappointing, coming from the photography world, there is no off-the-shelf way of triggering several actioncam-type cameras on & off at the same time, even within one brand. That’s pretty easy to do in the big camera world.
