I think what is happening is a trick I like to use.
whoever told you their are "TRICKS" told you wrong, if you did not recieve this "Tricks Theory " from anyone, then you need to reassess your thought process on BFM
I use it when I am being chased going over 350 mph and being caught for instance a high con dove on my six I drag him out but he is gaining. at about 1.5k I climb a bit and deploy 2 notches of flaps thus initiating the f4u's best turn radius
not all F4U series planes best turn radius is at the "2 notches of flaps extended" heck prob most of them are not, some may have a better "Sustained Turn Rate" at 2 notches, but not best turn radius, and then some have a better turnrate & Turn radius with all notches extended.......
I recommend you learn your F4U planes and their abilities and weaknesses
I quickly nose down so he has to re adjust his aim quickly by this point he is about 800 ish out I flatten my wing to him and quickly pull into his flight path as he probably didnt lag persuit and went for the shot if he did follow lag I generally just full flat turn or yo yo as needed and initiate some rolling scissor once I am ready.
you can not initiate a rolling scissors, "You can try to setup and overshoot and if lucky initiate/attempt a rolling scissors if your opponent takes the bait"
I have this win for me mostly against spits who rely on their turn to win but the 2 notch flapped f4u is a better turner
WRONG......... if you are beating spitfires in the F4U by just outturning them, it is not because the F4U turns better than the spit, It is because the person you are up against is not advanced as much as "you might be" in dogfighting..... or you are not straight up "outturning them" you are doing somethingmore than just turning....
but doesnt gain e so it will win a flat turn but lose the vert game this way. So if the spit resorts to going vert I flatten and scoot away as the f4u is faster than the spit just takes time to build the speed.
the spitfire can out accelerate the F4U initially, so you are getting lucky from your opponents poor gunnery......
I am not trying to pick on you, Greziz, but your description of "what to do" was very easy to show what was wrong information, Sir.....
hope this helps both the OP and you, in learning some untruths from your post
