and go to SIMHQ , air and look for library, then look for articles by Andy Bush which describe scissors and rolling scissors, they are the best Iv found.

In general I have found that in 99% of the times if you are low and slow in a FW with a plane on your 6 then you will be shot down, it does not pick up speed well so you cant escape, all the bandit has to do is sit there and wait and he will get the shots he needs.
Its only advantage in a dogfight is in its roll rate so thats why its good in scissors. You have 2 options in the scissors depending on what you want the outcome. If you wish to just try to survive and escape keep the roll as flat as possible, you use rolling scissors like gun jinks (e.g. sharp rudder or stick inputs) to put off his aim, while trying to extend towards friendlies. If you want to try to make the opponent overshoot then do wider rolls as it looses speed at any AoA
