The Ki-84 ko is the first truly fast aeroplane in the Japanese tech tree. Equipped with a 2,000 hp engine, this aircraft's performance is on par with that of the legendary P-51 Mustang. However, unlike the Mustang, the Ki-84 has slightly better turning characteristics and climb rate thanks to its lighter weight. This being said, the Ki-84 also has good energy retention, so try to make your opponent bleed energy to have an edge. The Ki-84 was also one of the first mass-produced Japanese aircraft to come equipped with armoured glass, armour plates and self-sealing fuel tanks, but the armour is still lacklustre compared to its Russian and American counterparts. However, as always, not everything is perfect. The aircraft controls stiffen significantly at speeds above 630 km/h, making even slight adjustments to heading impossible. Thus, at higher speeds, its elevator suffers. The Ki-84 also suffers a lot when no modules are researched, making the aircraft almost useless until modifications are unlocked.

The Ki-84 ko is a very good multi-purpose fighter, its capable of energy fighting and sustained dog fighting making it a menace to face with few enemies matching it, it takes a rather skilled pilot to shake these off as they have great turn fighting capabilities, good climb rate and a decent top speed for their BR.

It is important to remember that when uptiered, you will be fighting aircraft such as the [[Spitfire F Mk 22]], which is faster both in a straight line and in a shallow or step dive, the best way to reliable deal with this threat is to coax your enemy into a rolling scissors or sustained dog fight as the Spitfire F Mk 22 does not have a faster turn rate than the Ki-84 ko, alternatively if they do not dog fight and they are above you, you can force an over-shoot with some defensive flying and catch the Spitfire either as it passes or when it starts to go back up into its climb thanks to the Ki-84 ko's good climb rate.

The Ki-84 ko is not very well armoured at all and should avoid any head on engagements or well defended aircraft such as [[B-24D-25-CO|B-24's]] as it is rather fragile to enemy fire. The weaponry isn't spectacular either and may require a bit of practice as they are rather lack luster compared to other planes you will fight.

As a Ki-84 pilot your safest bet is to climb above your opponents and pick and choose your battles, often a good strategy to use is to hunt down the highest altitude enemies and pick them off one by one, remember not to waste all the altitude you have obtained as altitude is your friend in the Ki-84, whether you prefer Boom and Zoom or Dogfighting, the Ki-84 ko is sure to please you.

'''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 guns have enough fire rate to put quite a few projectiles into the target in one pass. However the Ki-84's disadvantages are the limited damage, rudder efficiency at high speeds, the rather poor 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 not usually cripple the enemy given the projectiles' lacklustre damage, so multiple attacks are needed to destroy one plane. 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 not enough to cripple a twin-engine aircraft given the slow velocity, light projectiles and low one-second burst mass. 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 2 MGs perform well in killing trucks, AA guns and artilleries as they have plenty of ammo, but avoid wasting cannon shells. However, 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 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.
 +
* [[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 mediocre damage, 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 Ki-84 ko is the first truly fast aeroplane in the Japanese tech tree. Equipped with a 2,000 hp engine, this aircraft's performance is on par with that of the legendary P-51 Mustang. However, unlike the Mustang, the Ki-84 has slightly better turning characteristics and climb rate thanks to its lighter weight. This being said, the Ki-84 also has good energy retention, so try to make your opponent bleed energy to have an edge. The Ki-84 was also one of the first mass-produced Japanese aircraft to come equipped with armoured glass, armour plates and self-sealing fuel tanks, but the armour is still lacklustre compared to its Soviet and American counterparts. However, as always, not everything is perfect. The aircraft controls stiffen significantly at speeds above 630 km/h, making even slight adjustments to heading impossible. Thus, at higher speeds, its elevator suffers. The Ki-84 also suffers a lot when no modules are researched, making the aircraft almost useless until modifications are unlocked.

This aircraft should be played as it appears: a lightweight Japanese version of the Mustang, retaining good engine performance, decent climb-rate, high diving performance, with solid armament.

Usage in battles

Realistic Battles

The Ki-84 ko is a very good multi-purpose fighter, its capable of energy fighting and sustained dogfighting making it a menace to face with few enemies matching it, it takes a rather skilled pilot to shake these off as they have great turn fighting capabilities, good climb rate and a decent top speed for their BR.

It is important to remember that when uptiered, you will be fighting aircraft such as the Spitfire F Mk 22, which is faster both in a straight line and in a shallow or steep dive, the best way to reliable deal with this threat is to coax your enemy into a rolling scissors or sustained dogfight as the Spitfire F Mk 22 does not have a faster turn rate than the Ki-84 ko, alternatively if they do not dogfight and they are above you, you can force an over-shoot with some defensive flying and catch the Spitfire either as it passes or when it starts to go back up into its climb thanks to the Ki-84 ko's good climb rate.

The Ki-84 ko is not very well armoured at all and should avoid any head on engagements or well defended aircraft such as B-24s as it is rather fragile to enemy fire. The weaponry isn't spectacular either and may require a bit of practice as they are rather lacklustre compared to other planes you will fight.

As a Ki-84 pilot your safest bet is to climb above your opponents and pick and choose your battles, often a good strategy to use is to hunt down the highest altitude enemies and pick them off one by one, remember not to waste all the altitude you have obtained as altitude is your friend in the Ki-84, whether you prefer Boom and Zoom or Dogfighting, the Ki-84 ko is sure to please you.

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 guns have enough fire rate to put quite a few projectiles into the target in one pass. However the Ki-84's disadvantages are the limited damage, rudder efficiency at high speeds, the rather poor 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 not usually cripple the enemy given the projectiles' lacklustre damage, so multiple attacks are needed to destroy one plane. 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 not enough to cripple a twin-engine aircraft given the slow velocity, light projectiles and low one-second burst mass. 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 2 MGs perform well in killing trucks, AA guns and artilleries as they have plenty of ammo, but avoid wasting cannon shells. However, 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.
  • 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 mediocre damage, 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.

Pros and cons

Pros:

  • Incredible rate of climb compared to other fighters such as the Ki-61 series and the A7M2
  • Effective top speed and energy retention allowing for the effective use of "boom and zoom" tactics
  • Great acceleration allowing speed to be regained quickly after duels
  • Reasonable performance at high altitude
  • Much better dive speed than the earlier Ki-61 series
  • Good manoeuvrability at lower speeds
  • Good energy retention
  • Thanks to its lack of canopy frames, a clear all-round canopy view especially over the nose gives it a huge advantage in simulator
  • Centre of mass is behind main landing gears, allowing it to break continuously until it stops. Does not need to worry about propeller strike
  • Engine cools down fairly quickly when overheated
  • Simple to use with MEC

Cons:

  • Lower maximum dive speed than its American counterparts such as F-82
  • The "jack of all trades, master of none" character of this aircraft makes it difficult to play as pilots will need to adapt their playstyle to counter specific aircraft that they are facing, subsequently requiring a fair degree of knowledge over the strengths and weaknesses of each aircraft that they will encounter
  • Somewhat vulnerable to damage, don't like to take hits.
  • Reasonably slow roll-rate causing this fighter to be vulnerable against Japanese fighters or the Fw 190's which are the typical opponents
  • Lock-up of the rudder above 650 km/h renders dive bombing or high speed boom and zoom less effective
