Realflight G2 add-ons
$40?? No, they're not worth $40.....They are worth $25 - $30 as Cyberpilot said. Seriously though, I like them a lot....it makes flying online in the multiplayer mode much more fun, since if you don't have the add-ons, other people that have the add-on's and are flying planes from them will show up on your screen like they're flying PT-40's.
