The only thing I’ve seen is when someone is using a head tracker, they can look at different angles that place the plane pretty much anywhere they like. I’m guessing the Asobo dev’s thought they were making an “artistic” choice with this angle. If you use the drone as a following camera, you should be able to control its angle, but I’ve never tried that. The only time I use the drone is to explore ground scenery. There may be some entry in a cfg or xml somewhere to fix the chase angle, but I’ve never looked for it.
