it is lag.
what you are seeing is a plane in a stall, usually self-induced and the plane is winging over.
take a 190 for example. at low speeds (225 IAS) the wing-over is really nasty, and a snap stall happens in a fraction of a second. the plane goes inverted, and the pilot tries (usually) to recover. what you see on your FE is a plane flipping inverted, then righting itself quickly.
then net code can;t send that many packets in the time it takes for a plane to snap-stall so you get that flippy thing.
imagine it like a cartoon. ever make one you flip yourself? if there is too much action between 1 frame then the next it looks funny. thats pretty much what you are seeing.
as for "don't move your controls so rapidly" that is generally not what is happening. i can make a C.205 flip over at will then right itself (though still with the stall horn blaring) in about 1/2 a second. go around 200 IAS, then pull up and to the left with NO rudder input, when you are at the point where the nose of your plane is about 75 deg kick the rudder right hard and fast. just 1 simple input will cause the plane to flop over dramatically. mind you it is not totally easy to recover from this, but is a quick example of self induced stall. on the chasers FE the plane will flip, then drop in altitude, then flip again all in the matter of about 1-2 seconds.
mind you this can be done intentionally, or if you notice the manuever mentioned, it is similar to a barrel roll, it is just done more violently.
in the heat of the battle with that con on your stick you sometimes push too far, or quickly, and the plane's FM responds. the net code just cant keep up for the guy chasing you.
whether it is deliberate or accidental is up for debate. take the C.205 example above. if i was being attacked by a higher speed spit from the 7oclock position i would think to try a barrel roll going up the the left for an immediate defense. it makes him turn tighter bleeding E, and there is always the possibility of an over shoot.
well lets say i just got finished with another spit, and my E state is low. the C.205 turns terrible to the left and doing that manuever will generally result in a stall unless you have TONS of E.
even so, i want to try at least to make my evasive, and maybe i didnt judge the E state of the spit well. maybe he has chopped throttle, and is waiting for my roll. as i go up and notice he is following with ease, i start to push harder to make the move....
but i snap-stall over losing control. now the spit was clear on my 6 and he saw the flip, he pulls up to reset, and calls out on ch200 i am a stick stirrer based on what he saw on his FE.
now myself, i know right about where that snap is going to happen, and i try to ride that edge, hoping for the best, but preparing for the worst. not everyone has perfect control over their plane 100% of the time in Aces High.
there is 1 other type of "stick stir" i can think of. in fact a guy i was fighting the other day did it intentionally, and we both laughed. he said "it was all i could do you had me".
on the deck in a 190 chop throttle to zero pull up slightly and roll 1 way or the other. you will enter a snap stall similar to the C.205 and you will bleed E drastically. you plane will be in a total stall, and unless you are decent, you will not recover.
if you are able to recover you opponenet will have overshot you almost 99% of the time.
either way that is also not a "stick stir" but a induced stall counting on the net lag to not relay enough packets.
oh well thats my take on stick stirring
