This sunday I did my maiden flights in FPV. Had 16 hours training in Liftoff Sim, bought an FPV drone with DJI 03 Air Unit and mouted the OA3 on top. If it was only about video quality the O3 Air Unit alone was sufficient enough, but if you want the engine noise recorded you need additional gear on the drone.
Settings Ultra Wide, 4K30HS, everything else on Auto. Camera survived two crashes into the soil/peat without any scratches or bruises.
Thanks a lot. Did not expect to fly some acro on the very first day at all flying manual. It's been a great feeling.
For the camera settings, I did not had any plan to modify the settings before the first flight. Next time I definitely will! D-CINELOG and manual exposure. This should give better results.
