It's always great to see interest in this venerable old sim (given that there's still nothing like it out there), but I thought the low-level flight went on for too long -- the terrain popping looks awkward these days, and the sequence showed nothing of the aircraft's aerobatic abilities -- and then when you did switch to aerobatics (and a gut-wrenching display it was, I must add :) I thought you had the opposite problem of being too high up... the terrain areas being as small as they are, the repeating textures were a bit too obvious at that kind of altitude.
Neat stuff, but not quite in that sweet spot needed to make FU1 look its best in this day and age. But hell, I'm happy to see anyone doing anything with Flight Unlimited :)
If only there was a way to make the smoke trails last longer, I think some really funky videos could still be made.
