My thoughts:
I agree that perking the 3 cannon La-7 is appropriate, something small but effective like the F4U-1C.
It's apparent that the recent addition of the Ki-84 has generally gone unnoticed in its effectiveness at dealing with the La-7.
Against all aircraft:
Ki-84 - 1.34/1
La-7 - 1.29/1
Against each other:
Ki-84 - 1.08/1
La-7 - 0.92/1
That's quite interesting, the mighty La-7 doesn't dominate the Hayate. And, that's in spite of being nearly 50 mph faster on the deck.
We can discount the newbie argument, because there's plenty of newbies flying the Hayate.
It boils down to the Ki-84 having more strengths and less weaknesses than the La-7, especially when you know how to set up the Ki-84 for maximum performance.
Fly with 50% fuel max... Need more range, take drop tanks. Use manual trim. In manual trim the Hayate pilot is not fighting his own elevators at high speeds. At 50% fuel, the Ki-84 has similar range to the La-7 with full bags. Climb rate is virtually the same under these conditions. Roll rate goes to the Hayate, especially at medium to high speeds where it excels. Turning ability is no contest, The La-7 is badly outclassed. Scissoring with the Ki-84 is certain death. Should the La-7 pilot find himself with the Ki-84 above him or Co-E, he can always bunt over and try to dive clear. Well, the Hayate can dive too, and if its under manual trim, it can turn just as well as the Lavochkin at high speeds. Plus, if the La-7 driver isn't careful, he will have serious problems with control stiffening. In all probability, if the La-7 doesn't auger, he will be able to get out of gun range... And he better keep on running too if the Ki-84 doesn't take the bait and remains above him. If the La-7 wishes to reverse and engage, he'll have to climb. Climbing will make him slow and getting slow around the Ki-84 means getting dead.
Rope-a-dope; I've had a few La-7s try this. They died. Trying to rope a Hayate with decent E is not a good idea. If you guys think the Niki is the premier UFO, you haven't seen the Ki-84 fight in the vertical. We have compared the Niki and Hayate head-to-head and the Hayate is superior in every category of performance. Should you think that trying to rope the Hayate is a good idea, consider this: Long after the La-7 has stalled and tumbled out of its climb, the Ki-84 is still climbing with complete control in every flight axis, right down to 50 mph. Indeed, the Ki-84 is the king of the spiral climb. You can take off, and right from the runway, pull into a climbing spiral. Averaging almost 4k per minute, you can spiral up to 12k, and never go outside of the base perimeter!
So, the La-7 has but two advantages over the Hayate. Those are pure speed and level acceleration. It needs those advantages to survive, because it is equalled or inferior in every other measure of performance. The standard La-7 practice of taking the fight into the vertical doesn't work against the Ki-84. Suddenly, the Lavochkin pilot must learn use similar tactics that P-51 pilots must use against the Spit IX; stay fast, don't climb steeply and never turn hard. And those are survival tactics, not fight winning tactics.
In my opinion, the addition of the Ki-84 has significantly changed the dynamics of the MA, and changed it for the better.
