| − | + | The Hei Hayate is the same great Hayate but with 2 x 30 mm cannons instead of 2 x 20 mm. Although this might not seem too important, one hit from a 30 mm high explosive shell will easily send your enemies to their doom. This solves the problem of the lacklustre 20 mms. When up-tiered to jets, focus on taking out propeller-powered aircraft. Climb high, and gradually work your way down. 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 such as pulling evasive manoeuvres 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 are typically easy to catch) or a prop fighter, will not be much for you to do. 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 at least ''three'' air targets before breaking even with this aircraft's repair cost! | |

| + | * 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 2x 250kg 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 turn fighters, 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 30mm 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. | ||

| − | * [[Me 264]]: | + | * [[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. |

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. |

The IJAAF approached Nakajima in 1942 to upgrade it's Ki 43 fighter. They realised the need for a more solidly armoured, faster, and heavier armed fighter. 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. | The IJAAF approached Nakajima in 1942 to upgrade it's Ki 43 fighter. They realised the need for a more solidly armoured, faster, and heavier armed fighter.

Description
The Ki-84 hei Hayate is a rank IV Japanese fighter
with a battle rating of 7.7 (AB) and 6.3 (RB/SB). It was introduced in Update 1.37.
General info
Flight performance
The Hei Hayate has identical flight performance to the preceding Ko and Otsu versions - same good turn rate, climb rate, and compression. As with the other two, use your excellent vertical energy retention and good manoeuvrability to your advantage. You can outturn all Allied aircraft except the Merlin Spitfires and the P-59 using combat flaps. You still retain the reasonable roll rate and abysmal rudder of the other Hayates.

Usage in battles
The Hei Hayate is the same great Hayate but with 2 x 30 mm cannons instead of 2 x 20 mm. Although this might not seem too important, one hit from a 30 mm high explosive shell will easily send your enemies to their doom. This solves the problem of the lacklustre 20 mms. When up-tiered to jets, focus on taking out propeller-powered aircraft. Climb high, and gradually work your way down. 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 such as pulling evasive manoeuvres 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 are typically easy to catch) or a prop fighter, will not be much for you to do. 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 at least three air targets before breaking even with this aircraft's 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 2x 250kg 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 turn fighters, 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 30mm 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: 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, Spitfire, etc: If you see these turn fighters 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.

History
The IJAAF approached Nakajima in 1942 to upgrade it's Ki 43 fighter. They realised the need for a more solidly armoured, faster, and heavier armed fighter. 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.
