Watch how people get you off thier tail and try to do the same things. There are a lot of referrence materials posted by some very good pilots in other threads (such as help and training) and thier web sites.
Learn how to use flaps.
Be concious of your "E" state. (ie. don't EVER get a P47 slower than about 250)
It's also HUGELY important to fly the plane that you choose in a way that optimizes what it does well. (for example, don't try to out run a P51 in a F4F, or try to outturn a Spit in a 190. Don't try to out roll a 190 in a Zero at over 300 mph. As a matter of fact, don't ever get your Zero over 300 mph

. the list goes on and on and on.....) It's a matter of knowing the characteristics of the plane you are flying, using them to your advantage and knowing about a half dozen manueveres (for starters.)
but most of all PRACTICE.
But aside from that.... the best way I found to get someone off my six is to help your friends (countrymen) when someone is on THIER six by doing 6 calls clearing thier tails. It's called teamwork.
