Title: Pyro Ki84 performance issues

In the last 2.01 patch, we’re just going to continue to make some fixes and there are some performance issues with the Ki-84 that I plan to change.


Can you go into further detail about what will be changed?

Float like a butterfly

Sting like a bee

Accelerate like a missle

Roll like a spiral pass

Turn like tetherball

Slow but very agile.  323mph on the deck and 386mph at 20,950ft.  Climbs at ~3,750fpm initially and accelates pretty well at 200mph, but nothing to get exited about.  It turns well, though a Spit V will beat it.  The P-51 or P-38 will out turn it due to their combat flaps until the speed gets below 165mph and it can deploy it's combat flaps.

It performs very well in the verticle and it rolls very nicely, particularly at mid-range speeds where it can almost keep up with an Fw190 or F4U in terms of roll.

It's firepower is quite solid.  I find the guns to have a nice feel to them, better than the German guns.

I'm kind of curious as to how the Ki will be nerfed too... it doesn't seem all that great.. it is a good plane, but it is no Spitfire.  Not even in the same category as the La-7.

Urchin,

It may not be a reduced performace change that Pyro has in mind.  There are a lot of things that could be adjusted, some would help it and some would hamper it.

If I were to guess though, I say the adjustment will have something to do with it's stall speed and extreme low speed handling being too good right now.  It could also be a small bumb in speed, though 1mph to 2mph off the intended speeds doesn't usually get attention.

I think its most likely to be improved with more engine power then tuned down in any way.

Urchin, the Ki84 flies so well it gives the SpitV a real run for its money.

It is more than a match for a P38, and the few times I fought a P51D in a Ki84 I won.

It's way more uber than some think. And it's not a bad thing. We now have something to kill the La7, the SpitV, and still slow enough not to be listed with them in speed levels.

I'm not entirely sure you meant tho say the Ki-84 is slower than the Spit V, but it sounds like that is what you are saying.

The Ki-84 is a bit faster than the Spit V at all altitudes, increasingly so as the altitude gets higher.

It is 58mph slower than the La-7 at sea level though.

Current Ki84 with 50% fuel climbs at 3900 fpm at sea level (166 mph) with a range of 114 miles. At 10k it still climbs at 3750 fpm and range increased to 115 miles (134GPH), all that without reheating the engine with WEP. Test done offline.

A SpitV achieve similar results only on WEP, 160 GPH, range of 54 miles. We be should compare Ki84 against SpitV with double the fuel load than Ki. That without considering the limited wep time of the Spit.

Now we have two miracle engined planes, Ki84 and Yak9U.

Trim Trim and more Trim. Use the trim and you will soon be turning with anything at speed. I can pull black out turns at any speed.

How is that a "miracle" engine?

You make no sense.  The Ki-84's engine puts out a lot more power than the Spit V and you're surprised that it allows it to climb as well despite being heavier?

Icemaw,

Yes, that is true in the short term, but once the Gs drop to below the blackout threshold the American aircraft turn better due to their high speed combat flaps.  Once the speed drops to the point where the Ki-84 can get it's combat flaps into play it turns back to the Ki-84's favor.  The problem the Ki-84 has is that it is quite dificult to keep it that slow and you can easily find yourself above your flap speed and handing the advantage back to the Americans.

Pyro, you won't change N1K2-J's flight model in it?
IIRC busa mentioned it, it's not correct.

IIRC Pyro intends to reduce the Ki's climbrate to be more inline with its specs.   I believe they discovered (busa) that the climbrate isn't falling off with altitude as it should.

While the American fighters (P-51s, P-38, F4U and P-40) can get their flaps down at higher speeds, it won't help them at all. Why?
Because the Ki-84 can easily cancel that advantage by pulling the nose high. Of those listed, only the P-38 can manage that, and the Hayate is still markedly superior. If you get the flaps out in any of the above, while fighting a Ki-84, you will die. That's always the option with the Hayate, you can high yo-yo these planes to death.

What I like most about the Hayate is its ability to equalize E states very quickly. If you are Co-E with the Ki-84, you are likely to die. I find that 109s and La-7s continue to try fighting the Hayate in the vertical. And, they continue to pay for that.

Most guys have no clue what the Ki-84 can do. I had an La-7 attack me with a ton of E. 60 seconds later he was on the deck trying to scissor with the Hayate...Something he should not have tried. Another La-7 dragged me to his base where more fighters were waiting. Down went the La-7 and two SpitVs that tried to help him. In my opinion, the Ki-84 can turn with the SpitV once it gets the fowlers fully out. However, you don't have to do that since you can simply pull the nose high, which the SpitV cannot match. I prefer to keep the Hayate near corner velocity and use vertical maneuvering to gain the advantage.

I'm hoping that Pyro's adjustments include improved acceleration. This fighter should accelerate better than it does. I also hope he addresses the elevator issue. The Ki-84 shouldn't need so much nose-down trim at medium speeds. Climb rate seems ok, it drops off considerably between 8k and 14k, but levels off when the second stage of the supercharger kicks in and remains constant until 18k were it begins to drop off again.

My regards,

Widewing

I just want to know what will be changed.

IRL  a spit5 would be hopeless outdated byt the tíme ki84 entered serivice.

ki84 can chose to fight when he wants,
because spit5 is slooow compared, again IRL.

ki84 has combat flaps, a feature shared with p51 mustang and some other brands,
making turning easier ( or at least should be easier to turn)

ki84 was fast and agile,but unreliable engines and 1944 production quality made it hard to maintain in the field.

3900 fps, 134GPH, no heating problems, range of 115 miles at max military power with 50% fuel at 166 mph while climbing.
Do you need more?

I'm thinking that Mandoble has found a worthy successor to his Spit whines of old.  ;)

So you're saying that a plane that consumes fuel faster at MIL power than a Spitfire Mk IX or Bf109G-2 is unbelievable?

It doesn't have heating problems in AH because it doesn't have any WEP.  It consumes fuel slightly faster than the Spit IX and markedly faster than the Bf109G-2 at MIL power.  It carries more fuel than both combined, IIRC.

I don't understand what the problem is here.

Does it mean that a/c without WEP dont overheat and/or can push the throttle to gate without limits? C'mon Karnak ....

The real C.205's DB605A didnt have any WEP, however AH's C.205 has his maximum power limited to 5 minutes.

I know this is a game but some consistency would not hurt.

In AH that is one of the characteristics of not overboosting.  All aircraft that run at MIL power, even if they have an overboost, do not overheat.

In reality running at overboost did not overheat an engine under normal circumstances.  The effect it had was to reduce the time between maintainance overhauls.

Ok, then go and compare Spit IX, 109G2 and Ki-84 performance all at MIL, not just Ki84 vs anyting on WEP.


Nah Blue Mako, it is simply that some people here think AH Ki84 is a crappy plane while it is not.

First of all, the climb rate is in FPM, not FPS.  A bit anal perhaps, but accuracy is important if you are going to post test results.

Second, 3900 FMP is a little higher than most folks have found it to be in testing, are you rounding that up a bit?  Its not far off the official numbers of around 3700 FMP.  It should begin to fall off at higher altitudes.  Did you repeat the tests to check for accuracy?  Or is this a one-off test?  And I'm not saying your test results are WRONG, I'm just asking.

Third, why should the Ki-84 exhibit heating problems at full throttle use?  Nothing else in AHII does, are you suggesting that they include this as a feature for all planes?  Or are you trying to say that the Ki-84 in particular should be handicapped in some way that no other plane is?  If so, why?  

Thanks.

Hammer has documented the climb rate of the Ki-84 on netaces. You can see it here: Ki-84 climb (http://www.netaces.org/ahplanes/japan/KI84Climb.pdf)
