combat tricks
On a more serious note, it is worth while to try to watch and follow or "intercept" other sunday flyers. Most sunday flyers put around in a basic left hand pattern. Get used to getting behind them, and watching for their turn, and then turning with them. Just be sure to do it at a distance so they don't notice, or better yet, do it with friends who don't mind. You don't even need to do it with your combat plane. The important thing is getting used to watching the other guy while staying with your own plane.
While you are new, you can live by "when in doubt, pull up then breathe". If you loose sight, orientation, or anything at all feels odd or panicy, pull full up elevator with no aileron, and take a breath as your plane loops and you catch back up with it. It's not uncommon for the plane to get ahead of you. As long as you don't get in the habit of casing guys low inverted, full up elevator will 99% of the time be a safe thing to do.
