I found this very competently done video by chance while checking the homepage of RealAir for news (I use their SF260).
If you don't know them and use FS8, 9 or X, check their planes, especially the SF260 which founded their fame - the formation flying in the video is done with that plane, so you see you do not need IL-2 for some dogfighting to do in civil flightsims!
. Concerning flightphysics and crispy clear 3D gauges with ultra-smoot needle-movement, their packages set the benchmark for the genre.
