Sfaust,

The official flying shuts down at 4PM. Normally people are flying until 6PM after that, with regular frequency control. (The transmitter impound closes at 4PM). You should have no problem flying your other stuff after hours.... However, don't miss the fun at the bar @ the headquarters hotel.

Down_shift,

Typically around 200 pilots. Last year was low @ around 170 pilots because of a bad weather front, but normally the weather is perfect.
