The Hei Hayate is the exact same plane as the Ko and otsu - same good turn rate, climb rate, and compression. Having flown those two, the Hei Hayate is quite literally the exact same. As with the other two, use your excellent vertical energy retention and good maneuverability to your advantage. You can outturn all allies except the Merlin Spitfires and the P-59 using combat flaps. You still retain the OK roll rate and abysmal rudder of the other Hayates.

The Hei Hayate is the same great Hayate, but with 2x 30mm cannon instead of 2x20mms. Although this might not seem too important, one hit from a HE 30mm shell will easily send your enemies to their doom. This solves the problem of the lackluster 20mms. When uptiered to jets, focus on killing the props. Climb high, and kill. Once all the props are down, look for furballs and/or ground pounding jets. Swoop down on these people and destroy them. When jumped by a jet, there are a few things you can do - pulling evasive maneuvers and wearing the enemy's energy down. Call out for your jet teammates to help you out. When there is one more person running away, unless they are a bomber (which is easy food) or a prop fighter, you will be practically useless. Just go to the airfield, repair, and J out. Equip ground target rounds and bombs and try to wear down the tickets. Remember not to die. Survival is more important than ever in the Hei Hayate - your astounding repair cost means that you need to take down ''three'' air targets before neutralizing your repair cost!

'''Simulator Battles'''
 
−
 
 
−
* In Simulator, the Ki-84 is overall a decent plane to fly. It enjoys lovely visibility towards the rear, sides, above, and over the nose, giving the pilot great situational awareness. It has nice handling, good climb rate, great speed and acceleration. Armament wise, the cannons have destructive damage and enough fire rate to put quite a few projectiles into the target in one pass. However the Ki-84's disadvantages are the poor rudder efficiency at high speeds, the rather slow roll rate, and the compass at the front-right of the gunsight that can obstruct your view. This aircraft can be used in BnZ fighting, turn fighting, intercepting (to some extent) and some ground pounding.
 
−
* Before taking off, bring at least 30 minutes of fuel for longer patrol time. Set the convergence to around 250 m since your weapons have low velocity, therefore needing more precise aim at longer range. While your Ki-84 roars down the runway, you will notice that it shifts severely to the left, thus you must put rudder input to the right to taxi straight. As with other Ki series aircraft, only elevator trim is available, so when the stick is at its deadzone, the Ki-84 will roll and yaw to the left side. Therefore you always need to pull the stick a little to the right which can get a bit annoying. Usually, trim for around -1% when cruising around 470 km/h, around -5% when diving around 600 km/h, and when fighting at around 400 km/h no negative trim is needed. When carrying the 2 x 250 kg bombload, no negative trim is needed as well. Landing characteristics are forgiving: cut throttle to make sure you are not above 350 km/h before touchdown. Deploy combat then takeoff flaps to further decelerate in preparation for extending landing gears. Extend at around 260 km/h, control your descend rate throughout. Right before touchdown, deploy landing flaps. The gears are quite sturdy. You can break until the plane reaches full stop and not worry about propeller strike.
 
−
* For dogfighting, it is always safer to enter with an altitude advantage. Most dogfights in Sim happen around or below 3,000 m so the Ki-84 can easily climb up to that altitude. Once at an advantageous height, boom & zoom the enemies. The Ki-84 can easily accelerate to more than 550 km/h in a dive which is decently fast but requires more precise manoeuvres to get the correct lead, since the faster you go the smaller the shooting window is. Important note: when fighting above 550 km/h, you want to be more precise in the roll and pitch axis, since at this speed the rudder locks up severely, preventing you from making aim adjustments which negatively impacts the lead. You must pretend that your rudder doesn't exist and fully rely on the ailerons and elevators to lead. A successful pass will usually cripple, if not destroying the enemy. Aside from BnZ, the Ki-84 is also excellent at turn fighting - with the appropriate opponent, of course. Except a few dedicated turnfighters, the Ki-84 can out-turn and get on most opponents' tail with combat / takeoff flaps deployed, and can sustain its turning ability throughout the fight. The Ki-84's stable handling allows you to pull some tight manoeuvres, so don't worry too much about flat spins. If you become a prey, try some defensive manoeuvres like barrel rolls or disengage by diving steeply towards a nearby friendly airfield. Note that the Ki-84's roll rate is very average so avoid manoeuvres like scissors.
 
−
* When performing the "destroy enemy surveillance aircraft/attackers/bombers" task, it is crucial to constantly evade the turrets. If it is a bomber/attacker with decent defensive firepower or robust protection, then you might want to disengage after some attempts if you don't want to die. Pay special attention to any plane equipped with M2 Browning MG, they can critically damage the Ki-84 especially on the engine, fuel tanks, and pilot which can always lead to a later crash. Before attacking try to get an altitude advantage and perform deflection shots. To maximise the damage it is better to aim for their wings and engines, as the fuselage usually soaks up quite some bullets. Only fire when the bomber passes in front of your guns. This short window is enough to cripple or even destroy a twin-engine aircraft thanks to the upgraded 30 mm cannons, but it might require more passes to destroy robust targets such as B-29. However sometimes it only takes one bullet to set the target aflame. Do not follow behind a bomber's 6 unless you are sure that its tail gunners are unconscious. Chasing behind a bomber makes yourself pretty much stationary for the tail gunners, and you will be showered with bullets.
 
−
* For ground pounding, the best loadout is the 2 x 250 kg bombs. With an extra 500 kg of weight attached outside, the Ki-84 handles much clumsier during take offs, especially on the roll axis. Longer distance is needed before lifting off. It is quite easy to drop bombs accurately with a Ki-84 because this aircraft is able to quickly accelerate above 550 km/h in a dive, the bombs will travel an almost straight line towards the target, therefore you can aim the gunsight directly at the target and expect the bombs to land very close. After bombs away, immediately pull up. The 4 Ho-5's perform well in killing trucks, AA guns and artilleries as they are quite accurate, but do not waste cannon shells on these targets unless you must. Constantly watch your surrounding, especially your high 6 for any incoming enemies.

'''Enemies worth noting:'''
 
−
 
 
−
* [[Me 264]] - The Me 264 is armed with large calibre MG and cannons all over it, therefore tailing a 264 is basically suicide unless all of their gunners are knocked out. You can treat the 264 almost like a B-29 or B-17 as they are very similar in both design and defensive capabilities. It is best to head-on the 264 if you can as you can easily knock out the pilots due to its glazed nose while also taking minimal damage. However the bomber lacks a ventral turret on its belly, making it easy to deal damage from below, but be wary of the downwards facing rear 20 mm cannon near the tail. The safest way to attack is from a higher altitude, dive at an oblique angle and focus fire on the wings and nose. Never engage if you have no altitude advantage. Looking somewhat similar to a B-17, an Me 264 has huge back-swept wings with 2 engines on each, and a H-tail which differentiates it from a B-17/B-29.
 
−
* [[Yak-3 (Family)|Yak-3]] - This is a capable dogfighter or BnZ fighter that can be a huge threat. Although its firepower is not deadly, it can still critically damage a Ki-84. It is able to fly or dive at similar speeds, and can even engage a turn fight with a Ki-84 that is using takeoff flaps. The Yak-3 has a straight dorsal line housing an inline engine, a bubble canopy with a huge cooling intake sticking out the belly, and its symbolic, triangular wings.
 
−
* [[A6M (Family)|A6M]], [[Spitfire (Family)|Spitfire]], etc. - If you see these turnfighters on your tail try outrunning them by diving at around -40 degrees. The Ki-84 still remains responsive handling at 600 km/h, but its speed retention is not the best, meaning it will start to lose speed quickly and the enemy might catch up. If you are near a friendly airfield, great. If not, then hope for the best and run towards the friendly side. A Spitfire also has an uncurved dorsal outline and large, elliptical wings. A Zero has a radial engine that's usually painted black, rounded wingtips and stabiliser tips followed by a pointy tail.
 
−
* [[Ju 288 C]] - This is a very common bomber in air RB. Their tactics generally fall into two styles: shallow dive bombing and conventional climbing. For the ones that shallow dive towards a bomb base at the start of the match, think twice before engaging. The Ju 288 is very fast for a bomber, being able to reach >500 km/h in a shallow dive which makes it quite hard for an attacker to BnZ it, as it will be slow to catch up to it, giving it long enough time to shoot back. The Ki-84 locks up past 550 km/h, plus the small ammo capacity of its 30 mm cannons, it is best to leave it for heavy-punching teammates. As for the Ju 288 that climb, do not engage if you have no altitude advantage. It has numerous guns with great downward coverage, posing a big threat to the fragile Ki-84.

The IJAAF approached Nakajima in 1942 to upgrade it's Ki 43 fighter. They realised the need for a more armored, faster, and heavier armed fighter. Addressing the common complaints with the Ki 43 - low speed, lack of armor, and measly armament, the designers at Nakajima unleashed the Ki 84 - Japan's fastest propeller-driven fighter. Using the firm's own Homare, the Ki 84 was easily able to keep up and tangle with the P-51 and P-47. The Hayate was produced in three modifications - the same plane but with different armaments. These three are the ones you have flown in game.

Addressing the common complaints with the Ki 43 which were low speed, lack of armour, and measly armament, the designers at Nakajima unleashed the Ki 84 - Japan's fastest propeller-driven fighter. Using the firm's own Homare, the Ki 84 was easily able to keep up and dogfight with the P-51 and P-47. The Hayate was produced in three modifications which happened to be the same aircraft with different armament options. These three are available to fly in-game.

Description

GarageImage Ki-84 hei.jpg


The Ki-84 hei Hayate is a rank Japanese fighter with a battle rating of (AB), (RB), and (SB). This aircraft was introduced in Update 1.37.

General info

Flight Performance

The Hei Hayate is the exact same plane as the Ko and otsu - same good turn rate, climb rate, and compression. Having flown those two, the Hei Hayate is quite literally the exact same. As with the other two, use your excellent vertical energy retention and good maneuverability to your advantage. You can outturn all allies except the Merlin Spitfires and the P-59 using combat flaps. You still retain the OK roll rate and abysmal rudder of the other Hayates.

Survivability and armour

  • 70 mm sloped (66°) bulletproof glass in the windshield
  • 13 mm steel plate behind the pilot seat
  • 6 mm steel headrest

Armaments

Offensive armament

Main articles: Ho-155 army (30 mm), Ho-5 army (20 mm)

The Ki-84 hei Hayateis armed with:

  • 2 x 30 mm Ho-155 cannons, wing-mounted (60 rpg = 120 total)
  • 2 x 20 mm Ho-5 cannons, nose mounted (150 rpg = 300 total)

Suspended armament

Main articles: Army Type 94 GPHE (50 kg), Army Type 92 GPHE (250 kg)

The Ki-84 hei Hayatecan be outfitted with the following ordnance:

  • Without load
  • 2 x 50 kg Army type 94 GPHE bomb
  • 2 x 250 kg Army type 92 GPHE bomb

Usage in battles

The Hei Hayate is the same great Hayate, but with 2x 30mm cannon instead of 2x20mms. Although this might not seem too important, one hit from a HE 30mm shell will easily send your enemies to their doom. This solves the problem of the lackluster 20mms. When uptiered to jets, focus on killing the props. Climb high, and kill. Once all the props are down, look for furballs and/or ground pounding jets. Swoop down on these people and destroy them. When jumped by a jet, there are a few things you can do - pulling evasive maneuvers and wearing the enemy's energy down. Call out for your jet teammates to help you out. When there is one more person running away, unless they are a bomber (which is easy food) or a prop fighter, you will be practically useless. Just go to the airfield, repair, and J out. Equip ground target rounds and bombs and try to wear down the tickets. Remember not to die. Survival is more important than ever in the Hei Hayate - your astounding repair cost means that you need to take down three air targets before neutralizing your repair cost!

Pros and cons

Pros:

  • Equipped with a very powerful array of weapons
  • Respectable speed for a prop plane
  • Decent high altitude performance
  • Capable turner
  • Solid energy retention
  • High muzzle velocity from both cannons
  • Insta-kill 30mms

Cons:

  • 30 mm cannons are mounted in the wings, resulting in significant convergence
  • 30 mm cannons fire fairly slowly, which isn't ideal for dogfighting
  • Poor ballistics from the 20 mm cannons at this rank
  • Can and will face early jet fighters, which negate your speed advantage
  • Useless when the engine's shot
  • Airframe is highly susceptible to battle damage, especially of the incendiary type

These three are the ones you have flown in game.
