General info

Flight performance

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.

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, but relatively lacklustre armament.

Usage in battles

RB:

The strong rate of climb of this fighter allows for a significant altitude advantage to be made in the beginning of battles. As this fighter is usually paired with the Soviets against the Japanese, make sure to utilise this advantage as your Soviet teammates and many of the Japanese fighters that you will encounter will be unable to climb as high as you. However, if German aircraft are present in the opposing team be cautious of climbing too high as they will be able to easily gain an altitude advantage over you.

When encountering Japanese Zeroes (i.e. the A6M5) do not attempt to "turn-fight" them. Instead, maintain your energy with a typical boom and zoom technique as they will be unable to match your altitudes. The N1K2 series and the Bf 109 series have greater rates of climb, but handle slightly worse at lower speeds, hence it is suggested that you should attempt to burn both your opponent's and your own energy using climbing corkscrew manoeuvres to bring both of you into your optimal fighting altitude (~4,000 m) at your best operating speed (< 400 km/h). Here you are more manoeuvrable and have a better chance at taking out these fast aircraft.

Due to your fairly weak weaponry, it is not advised to chase after heavily armoured bombers and instead focus on fighting enemy fighters. A potential approach is to support allied aircraft by maintaining a high altitude above them, preventing enemy aircraft from diving on top of your allies as you can control the airspace directly above them.

SB:

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 kph, around -5% when diving around 600 kph, and when fighting at around 400 kph 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 kph before touchdown. Deploy combat then takeoff flaps to further decelerate in preparation for extending landing gears. Extend at around 260 kph, 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.

Pros and cons

Pros:

• Strong 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
• Maintains a high degree of manoeuvrability at lower speeds
• Jack of all trades: nimble yet quick while having a good degree of energy retention, allows this fighter to hold its own against any fighter that it may encounter
• Thanks to its lack of canopy frames, a clear all-round canopy view especially over the nose gives it a huge advantage in simulator.

Cons:

• Not as manoeuvrable as the Japanese fighters that you will be facing at this tier, and struggles to contest the high altitudes of the Bf 109 series due to their superior rates of climb
• The "jack of all trades, master of none" character of this aircraft makes it difficult to play as pilots will need to adapt their play-style 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
• The weapons feel fairly lacklustre, with the 20 mm cannons having a reasonably low amount of ammunition (at least compared to the 12.7 mm machine guns)
• Severe lock-up of the rudder above 500 km/h renders dive bombing or high speed boom and zoom less effective
• Elevator locks up at high speeds preventing optimal usage of its great energy retention
• A reasonably slow roll-rate causing this fighter to be vulnerable against Japanese fighters or the Fw 190's which are the typical opponents
• Fairly susceptible to damage with fires being particularly devastating to this light aircraft
