Back on topic, the 109F vs F4U is a pretty even fight, as long as the F4U cant dive away and run.
The 109 has a small disadvantage in the turn radius, but also some advantage in the turn rate and climbing performance. Also the 109 has some torque too.
-dont try the flat scissors against the F4U. It will end up with your death pretty quickly.
-dont try the classical rolling scissors against the F4U, especially when it is following a downhill path. You have a chance, but only when the F4U is heavy and/or youre clearly superior to the Corsair pilot.
-the 109's game is the overshooting in the vertical rolling scissors, using hammerheads, etc. Force it.
Have fun!
