• Without load
• 2 x 50 kg Army Type 94 GPHE bombs (100 kg total)
• 2 x 250 kg Army Type 92 GPHE bombs (500 kg total)

Usage in battles

The Otsu modification is the middle child of the Ki-84 family, dropping the 12.7 mm heavy machine guns from the previous model in favour of two additional Ho-5 20 mm cannons, boosting firepower considerably. It retains the same strengths and weaknesses of said previous model. 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 solid turning characteristics and excellent 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 stiffer 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 and relatively lacklustre armament, although slightly improved from the previous model.

Unfortunately, the increased firepower comes at the cost of a higher battle rating, especially so in Arcade Battles. While a 0.3 BR increase in Realistic Battles isn't that bad on the surface, it allows you to face vastly superior aircraft such as the F8F-1B, Spitfire F Mk 24 and P-51H-5-NA that outclass you in almost every way. In arcade, the BR increase is a lot less subtle, a whole 1.3 BR increase to be precise. This increase causes the aircraft to occasionally be up-tiered into 7.0 matches with jet aircraft that will walk all over the poor Ki-84. Fortunately for the Hayate, it retains its advantage of excellent engine power - and by extension, top speed, climb rate and energy retention - and superb manoeuvrability that can turn with nearly every aircraft at the tier. While the Ko modification of the aircraft was brutal to play efficiently, the Otsu is a lot more forgiving, but can still wreak havoc in the hands of a skilled pilot.

Flying Styles

The Ki-84 Otsu is an aircraft that can tailor to any form of dogfighting its pilot can dream of. Its high top speed, decent acceleration, excellent manoeuvrability, great climb rate, and superb energy retention create a very stable platform when used properly, and a skilled Ki-84 pilot can single-handedly dictate the flow of the battle.

Basic Combat

The excellent energy retention combined with fantastic manoeuvrability allow the Ki-84 to be a very solid energy fighter that can easily compete with the 109's and the various Italian fighters at its tier. Ideally you should make use of the Vertical spiral or Zoom manoeuvre to bleed your prey's energy then pounce while they're recovering. Do take care to avoid roll-intensive manoeuvres such as scissors or lag rolls, as the Ki-84 has a mediocre roll rate that only gets worse with speed as a result of its severe compression.

Of course due to being a Japanese fighter, the naturally excellent raw manoeuvrability of the Hayate allows it to be a more than capable classic dogfighter who specializes in Turn-N-Burn tactics that can easily get on a bandit's tail. However it is noteworthy than the aircraft can struggle to regain its energy once it has bled it by turn-fighting, so avoid flat turns and go for climbing and diving turns instead so as to quickly regain its advantages.

Defensive Flying

Of course, there are scenarios where the Ki-84's pilot will have to go on the defensive. The aircraft cannot afford to take many hits, so avoiding as many shots as possible is mandatory for your survival. Defensive energy manoeuvres such as the Immelmann, Defensive spiral and the various Yo-Yo's should be your first choice when being attacked. If an enemy is diving on you, try to force an overshoot with your excellent manoeuvrability and engage while the enemy is zoom-climbing.

Pros and cons

Pros:

• Excellent manoeuvrability, among the best in its rank
• Competitive speed and acceleration
• Reasonably powerful armament with a decent amount of ammo
• One of the most underestimated aircraft at the rank
• Above-average climbing rate
• Very forgiving and enjoyable to fly

Cons:

• Severe compression beyond 630 km/h
• Ho-5 cannons have a tendency to spark
• Can face jets in an up-tier

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.
