I have a book about allied aces which has a maneuver in it which was used by p47 pilots.
I'll type it out whats written but unfortunately i cant post the pic.
'Used to defeat a better turning adversary, the attacker,in this instance thunderbolt ace bob johnson, barrel rolled away from his opponents turn allowing him to cut inside and acheive a firing position.
P47 approaches from high 5 oclock...
The german pilot throttles back and pulls into a hard left turn.
Johnson rolls in the oppersite direction to the germans turn using the barrel roll to defeat the superior turning ability of the Me109.Johnson ends up on the tail of the 109 in a firing position'
this is a manouver i use in 190s too. As they start their turn they expect you to keep coming and try to match the turn.Instead you barrel roll in the opersite direction of their turn and come back onto them nose low, you then dive slightly under them as you build speed and you have a nice closing and rising firing position.If they continue the hard turn you may well still miss this shot and find yourself being outturned again but generally I find in the 190 its already too late for them when the cannons hits , even a few times.In the p47 you can find even with a good burst it sometimes doesnt have the hitting power you need.If this happens the prudent pilot would break off and extend and look for another advantage position.
