General info

Flight performance

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.

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

Realistic Battles

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 capabilitys, 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-24's as it is rather fragile to enemy fire. The weaponry ins'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.

History

Describe the history of the creation and combat usage of the aircraft in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/History" (example: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).

Media

Excellent additions to the article would be video guides, screenshots from the game, and photos.
