HI Thing.
my opinion is that with an enemy on your six you would want to evaluate (quickly - lol) your relative speeds before starting a rolling scissor.
First you need to judge their speed. Are they faster than you? are they slower? Are they co-speed?
Enemy Faster - This is pefrect for your rolling scissors. Providing you have 600+yrds seperation to work with you will be able to 'drag' the enemy round in a tight flat turn and almost instantly you will be closing that gap as they gain on you. With correct timing you now can transition between the flat turn and a barrel roll to hopefully force a quick overshoot. As for flaps, it will be different every time. If you are both holding alot of speed you may not need the flaps but often dropping a notch or two at the top of your barrel roll will decelerate your aircraft a great deal more than flaps up as well as making your finer control as the speed drops off.
Enemy Slower - This is the worst time to try a rolling scissors in the P47. the enemy will almost certainly get off the throttle and saddle up if you start trying to scissor from a position of greater speed. This is the time to make use of the Jug's huge mass and dive away, gain some seperation and re-think your options. Another option would be to try and 'rope' the enemy with a series of spiral climbs using alot of flaps to hang high long enough, unfortunately most aircraft will easily outclimb the Jug so this is a risky business.
Enemy Co-speed - This will happen alot. You are trailing a spit16 at 800yrds and you both are going 300mph.
In this situation flaps are most usefull for deceleration. Your goal now is to trick your enemy into an overshoot. A usefull method is to dive and make them chase you. Once you have the enemy thinking you are running away you can drop your flaps as much as possible and attempt to barrel roll around them for an overshoot, or to start a rolling scissor fight.
In the Jug you are a big target, not only that but you have alot of weight giving you huge momentum. Early throttle work and quick kills are you forte.
You do not want to be engaging in a rolling scissor fight with most of the planeset, what you want to do is get in your enemy's head from the start and trick them into losing. you need to make your move, take them by surprise, and kill them all in the same 10 seconds.
Prolonged engagements of any kind do not lean in the P47's favour as a general rule.
In the link below you can see exactly what i mean by 'trick your enemy and kill them as FAST as possible'. I'm not in a p47 but infact something far more vulnerable and heavy. Check the flaps use, minimal if at all, each encounter will be different though.
