If anyone hasn't tried the racing, you really should. The time trials are a great way to get a feel for the course, and the network code improvements they made make the multiplayer racing almost seamless.
Even with the "standardized" flight models in the races, it's a ton of fun, and if there's a group of decent pilots, the identical flight models make for some really close racing. My first race, I started halfway down the field, but ended up winning by a fraction of a second over the airplane ahead of me, since my total time around the course was slightly faster.
