when I see these great videos, two things come on my mind:
1. prob animation ratio: as you can see, even real planes don´t have a proper one!! No, if I don´t like it, I play with different locked FPS, to get a nice representation.
2.SOOOOOUUUUUND!!!! I´m really happy with FSX, but our warbirdsounds are mostly superwhimpy. I replaced most sounds with offerings from Gary Jones and Nigel Richards, but that are fs9 sounds and a Seafury sound is not strictly correct in Bearcat, but that sound gives you really shivers. Did you see that Lightning video? Really funny, cause when the FDS Lightning came out, Smudge statet the turboless Red-bull Lightning would sound like a Fedex truck!...Hey that´s a heck of a Fedex truck.
OK, all that I want to say is, that there would be quite some money to earn from me, but just with some real noise...
Cheers, Thilo
