@JJJ65: Thanks for that! A few of these are not listed on Sandbaggers mod page, guess I'll find them here on the forum.
Say, you wouldn't happen to be an RB3D veteran, if you don't mind me asking? I know it's a terribly long shot, but I flew with a Czech back in the day.

@Polovski: Ha, busted! I'm indeed guilty of opening up as soon as I'm reasonably sure I'm seeing crosses. Just can't help it. :-) TrackIR would allow me to line up the sights with my head movements, right? I'm still desperately trying to convince myself that I shouldn't spend money on an accessory for a single game, but that might be a losing battle. Maybe a used older model...
