If there are a few people online choose a field a bit away from the action. Get a bit of height and speed before entering the frey.
Team speak is your friend.
Even to day with my microphone on the blink I was just hearing my team mates. A 109 got on my tail and a few of my team mates vectored my way to help. One guy was saying "turn him right , turn right , not than much!" and we set up the 109 so that my team mate could shoot him off my tail.
It's also useful for finding out where the action is.
Talk/chat to your team mates, work as a team and have fun!
Cheers
