The fact remains that the N1K2's flap system has never been modeled right in AH.
Unlike the US planes, where the combat flaps are engaged before executing the maneuver, the system on the N1K2-J requires the maneuver to start before they deploy.
The result comes with mediocre high speed manuvering until the flaps deploy; the basic wing shape, and dimensions is nearly identical to the A6M5, with quite a bit more weight and the horizontal stabilizer and elevators are the same.
Also unlike any other plane with manual flaps, the deployment is of course, uncontrolable due to the remote location of the system. Much like the 109's slats. They cannot be raised in slow flight to decrease drag and increase acceleration. It does have a few functions that prevents full-time deployment under a certain speed; angle of attack via the mercury tube is taken into account, so that if the pilot leveled out, the flaps would retract.
At present, the varying degrees of deflection of flaps as the N1K2 changes angle of attack and speed don't seem to be taken into account -- while the inital deflection doesn't create much drag, the others, like all other planes, creates a considerable amount of drag.
It should be experiencing a tremendous energy bleed off after maintaining and high G turn as the flaps deploy... acceleration should be even worse afterwards if the pilot does not maintain the envelope on which the flaps retract.
Anyways, the automatic system is rather complex and there isn't a terrible amount of information on how the whole system works, probably explaining why it was never included. However, make no mistake, it isn't modeled historically in that respect.
The best possible solution to it at present would to just make them manual to simulate deployment delay, drag, and other factors in the simplest and easiest way possible.
