In my understanding, it's not really advisable to get in a rolling scissor with a plane that roll better than yours. Then again, it's a difficult succession of maneuver that needs to be pulled perfectly for some time. A screw up on the part of the offensive plane (ie : not controlling it's forward momentum correctly by pulling longer helix than the defensive fighter) will give a chance to the defensive plane to reverse. So It comes down to skill (for which you need practice). I for one usually screw it up after 2-3 revolution, by stalling, not rolling fast enough and/or overshooting.
i'll make use of the surplus e (acceleration) that a 109 (and many other planes) has and go vertical...
That's a double edged sword. I've bee able to make quite few 109 auger in a rolling scissors they seemed to win (ie : in phase but no gun solution yet) by steepening the dive element of the roll just a wee bit. A f4u with full flaps and reduced throttle will not pick significant speed in a vertical dive where a 109 will accelerate quite quickly. They simply cannot follow the next pull up.
