The '''{{Specs|name}}''' is a rank {{Specs|rank}} German biplane fighter {{Battle-rating}}. This fighter has been in the game since the start of the Open Beta Test prior to Update 1.27.

The '''{{Specs|name}}''' is a rank {{Specs|rank}} Japanese fighter {{Battle-rating}}. It was introduced in [[Update 1.37]].
 
 
The Heinkel H 51 was one of the first aircraft which the German Luftwaffe (still operating in secrecy) tasked to be built. Brothers and talented aircraft designers Walter and Seigfried Günter were working for Heinkel Flugzeugwerke in 1931 when they developed the design for an advanced trainer biplane which was designated He 49. Though touted as a trainer, the aircraft had been designed as a fighter and with a few minor conversions, could be an operational fighter aircraft. After several iterations, the Luftwaffe ordered this aircraft into production as the He 51 in 1933.
 
 
 
Currently in service with Germany was the older Arado Ar 65 biplane which the He 51 was slated to replace, unfortunately by the time the He 51 A rolled off the production lines, it was already outdated, however, it wasn’t until after 150 were built that important modifications were made which resulted in the upgraded He 51 B. Of the 450 B variants built, 46 of them were modified by replacing the fixed landing gear with floats to allow the fighter to land on water. Later another 100 were built as the He 51 C variant which was configured as a light ground-attack aircraft.
 
 
 
Used initially in the Spanish Civil War, the He 51 showed to dominate over older biplanes, however, the advantage was short-lived as modern Soviet fighters and bombers arrived and the He 51 could no longer keep up with them. Operations for the He 51 converted to night fighting, however not long after that it was designated solely for ground attack operations. Though not seen as a fantastic aircraft, behind the scenes it had set the stage for the Luftwaffe years later when close support tactics were developed by Field Marshal Wolfram von Richthofen while flying a He 51.
 
 
 
When paired up against other reserve fighters in the game, the He 51 can hold its own, though it will not win any speed records, nor will its machine guns out fire some of the early Soviet fighters, however, there is a place for the {{PAGENAME}}. Diving straight into a cluster of fighters rolling around with each other is not the best tactic, it is better to pick a target and go after it, however, if cornered, the slower speed and manoeuvrability of the He 51 can get it out of tight spaces and potentially down a few enemy aircraft in the process. With two 7 mm machine guns, tracer rounds work best against early aircraft, especially those which are fabric covered and have non-sealing fuel tanks. Though the pilot may find themselves up-tiered against mono-wing aircraft of faster speeds, the {{PAGENAME}} can quickly turn the tables and put the faster enemy fighter on the receiving end of a stream of bullets, and only a few hits are enough to hobble the enemy aircraft allowing the Heinkel to catch up and finish the job.

The Ki-84 ''Otsu'' is a very stable platform that can easily compete with its contemporaries at the tier. It has an excellent top speed and acceleration for a Japanese aircraft, but is still quite a bit lacking when compared to aircraft like the late [[Bf 109 (Family)|109's]], [[Ta 152 H-1|Ta 152]], [[F8F-1B|Bearcat]], [[P-51H-5-NA|P-51H]], and the [[Spitfire (Family)|Griffon Spitfires]]. However, its most powerful trait is its excellent manoeuvrability. The Ki-84 will be able to outturn anything it faces with the usage of combat flaps that's not a Spitfire or [[Re.2005 serie 0|Re.2005]] (with the exception of other Japanese fighters like the [[A6M5]]). Overall it is an enjoyable aircraft to fly due to its excellent manoeuvrability, competitive top speed and acceleration, and smooth controls, but the pilot must take care at speeds above 630 km/h as the aircraft will stiffen up considerably.

Like many biplanes before and contemporaries of the {{PAGENAME}}, armour was not an option, survival was based on the pilot’s grit. Armour added weight, weight the early biplanes could not afford to carry and still be a viable fighter. Flying in open cockpit and fabric-covered aircraft, the only protection the pilot had was to place his engine between him and his enemy, otherwise, the pilot was vulnerable. Typically aircraft like this have the engine at the nose of the aircraft, followed by the fuel tank and then the cockpit, all three critical components relatively crammed together. The pilot’s toolbox had to contain situational awareness as he needed to know where the enemy was around him. Tracer rounds could easily ignite the fabric-covered aircraft or large fuel tanks, so it was imperative the pilot was the attacker, not the one being attacked and knowing where the enemies are at can help avoid getting shot at.

The '''''{{PAGENAME}}''''' is armed with:

When comparing offensive armament between reserve aircraft, the {{PAGENAME}} is on par with most nations, however, it lacks when compared to aircraft from France, Great Britain or the Soviet Union and to some extent the United States and their use of a heavy machine gun. The He 51 found itself between two great wars and to some extent was a fossil in regards to its armament. For a light biplane fighter, the {{PAGENAME}} only sported two 7.92 mm machine guns with a few options of ammunition types available for use.

* 2 x 20 mm Ho-5 cannons, nose-mounted (150 rpg = 300 total)
 +
* 2 x 20 mm Ho-5 cannons, wing-mounted (150 rpg = 300 total)
  
Some of the reserve aircraft the {{PAGENAME}} will face utilise a heavy machine gun, up to 4 x 7 mm machine guns and a couple of premium versions even pack on a massive (massive for a reserve aircraft) 20 mm autocannon. Though coming in at a severe weapons disadvantage in some instances, the {{PAGENAME}} can still dominate a match and come out the king of the hill. While the two 7.92 mm MG 17 machine guns may seem insufficient, they do a job and they do it well, though it may take a bit of practice to land the bullets where they will do the most damage.  
+
The Ho-5's are very volatile weapons when approached from a beginner's standpoint. Their reasonably high rate of fire combined with lower than average muzzle velocity and poor HE round makes it so that one must be fairly close to deal significant damage. Fortunately, they are quite accurate and do not jam as badly as its competitors such as the [[Hispano Mk.II (20 mm)|Hispano Mk.II]]/[[Hispano Mk.V (20 mm)|Mk.V]] and do not perform as badly as the Russian [[ShVAK (20 mm)|ShVAK]]. Your belt of choice should be ''Universal'' or ''Tracers'', with Tracers dealing the most consistent damage and being easier to aim due to not having to deal with the velocity difference between the HE shell and the Tracer shell.
 
 
Default ammunition what every pilot starts out with, though not the best it will cause critical hits and down enemy aircraft, though it may take a bit more patience and a few more rounds. When available to upgrade the ammunition belt modules, two other choices come into play which will allow the pilot to change tactics and fight more on their terms. Tracer ammunition is a fantastic choice for use against early biplane and monoplane fighters, especially since most of these aircraft are covered in fabric (as opposed to later aircraft covered in metal skin) and most if not all of the early fuel tanks are not self-sealing or do not vent exhaust gasses into the fuel tanks to stave off potential fireballs.  
 
 
 
Tracer rounds, though do little impact damage, their powerful punch comes from igniting aircraft on fire causing the enemy to fall to the earth in a flaming heap. One huge disadvantage to the tracer rounds is that it lets everyone know where you are with the bright coloured rounds flying through the air. To combat this, some pilots will switch stealth rounds, which just means that this belt is without any tracer rounds. Two advantages here are first, the removal of the tracer round adds in another damage round and secondly, there are no tracer rounds to give away your position, especially if your first shots don’t land where you want them to, enemy pilots will need to spend precious seconds looking around to find where the shots came from before reacting or they may react blindly and to your advantage. One challenge with stealth rounds is they are more difficult to tell where they are landing especially with distance shots and will take practice to know where they are hitting, though when used in close, they are easier to track and pack in a surprise for the enemy pilot they may not be able to recover from.

Early versions of the He 51 were not outfitted with bombs, it wasn’t later in the aircraft’s service it was deemed unacceptable as a fighter and was repurposed as a close support aircraft, not only able to use its machine guns to destroy ground targets but also being outfitted with six 10 kg bomb. At first one might think this is the equivalent of just throwing hand grenades out the cockpit, but this isn’t so. While these are not 50 kg or 100 kg bombs which will do significantly more damage against ground targets, the {{PAGENAME}} can still find success in bombing light targets, especially open-top trucks and anti-aircraft artillery. The first and second pass can be used for dropping the bombs on target and subsequent passes can utilise the machine guns to clean up. The {{PAGENAME}} has had a successful history of close support, even with a significant loss of aircraft in this role, tactics derived from its missions later became Luftwaffe doctrine for close-air-support and dive-bombing roles during World War II.

The ''Otsu'' modification is the middle child of the Ki-84 family, dropping the 12.7 mm heavy machine guns from the [[Ki-84 ko|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 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.
  
While hunting ground targets, it can become really easy for the pilot to have tunnel vision, only focusing on what is one the ground and destroying it. The pilot must also pay attention to their surroundings in the air to ensure an enemy fighter does not sneak into the air space and pounce on the ground pounder, if necessary the {{PAGENAME}} can covert from ground attack to air defence and attack, if successfully neutralizing the enemy fighter, the {{PAGENAME}} can then return to picking off ground targets.
+
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 fairly improved from the previous model.
 +
[[File:Ki-84 Combat image.jpg|thumb|A Ki-84 ''Otsu'' shredding a Hellcat's wing]]
 +
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.

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.

=== History and development ===

The design of the Ki-84 traces back to late 1942 when Nakajima accepted an order by the IJAAF to create an improved aircraft to replace the Ki-43 ''Hayabusa'' that was just entering service, with the requirement asking for a fast, nimble, simple but universal aircraft so that the Japanese could ease the stress on their factories. Nakajima used several elements from their previous designs - The Ki-44 ''Shoki'' and the Ki-43 ''Hayabusa'' - and took pilot complaints from said aircraft and worked on addressing them with the new aircraft, specifically the poor speed, climb rate, acceleration and weak airframe of the Ki-43 and the weak armament and flying difficulty of the Ki-44.
 
 
In the early 1930s, the most advanced biplane aircraft in Germany was the Arado Ar 65, though it was quickly becoming obsolete. The German Luftwaffe, operating in secrecy against resolutions set after World War I, did not want to fall behind in technology. Though military aircraft and vehicles could not be built, trainer and transport aircraft were designed and built but had a hidden dual purpose which would allow them to easily be converted into fighters and bombers. Heinkel Flugzeugwerke was one such aircraft manufacturer which was designing what was to be the Ar 65’s replacement. Günter brothers, Walter and Seigfried were the lead designers on a new biplane design in 1931 which labelled as an "advanced trainer", would easily be converted into a fighter when necessary. Early prototypes were designated He 49 with several variants resultant of modifications and upgrades performed to address shortcomings found during testing.
 
 
 
In 1933, the Luftwaffe ordered the He 49 (now designated He 51) into pre-production. The design of the aircraft is relatively simple, all-metal frame construction with a fabric covering. Like many early aircraft, it was powered by a v-12 engine, this one a glycol-cooled (ram air radiator) BMW VI engine and two 7.92 mm machine guns mounted in the upper fuselage/cowl of the aircraft allowing the pilot to point the aircraft where he wanted to shoot and then fire without having to make any considerations for convergence, with the exception of bullet drop over longer distances, however, when fired up close, the guns did considerable damage.
 
 
 
By the time the aircraft was rolling off the production lines in 1935, the He 51 A was already considered outdated which goes to show how fast technology was developing during these years. Modifications were made to the aircraft and the next in line production variant the He 51 B was produced in greater numbers and enjoyed early air superiority in the Spanish Civil War, only until modern Soviet fighters and bombers showed up.
 
 
 
Seeing that the He 51 B was no longer a capable fighter even as a short stint as a night fighter, it was quickly modified and the final production variant, the He 51 C rolled out as a dedicated ground-attack variant. The He 51 C was a very capable ground-attack fighter, coupled with its extreme manoeuvrability and slow loiter speed, the aircraft could attack a ground target and within a few seconds could have the plane turned around and be attacking again before any ground defences had the chance to regroup and retaliate. Towards the end of the Spanish Civil War, losses of the He 51 were starting to mount up as anti-air technology was catching up and more and more of the slower biplane were picked off from ground weapons.
 
 
 
It was during this time when World War I ace pilot Wolfram von Richthofen flew the He 51 in a ground attack role, through this process, he refined and honed his skills as a close support fighter. The tactics he learned through trial and error became invaluable later on during World War II when as a Field Marshal, he passed on these tactics and how to effectively dive bomb with aircraft. Though only 55 aircraft survived front-line service through 1938, they continued to be of use through the first few years of World War II as the aircraft they were originally designed to be, advanced trainers.

The Ki-43's performance issues was remedied by increasing the overall parameters of the aircraft and introducing the legendary ''Homare'' 18-cylinder radial engine that Nakajima themselves designed. The ''Homare'' proved to take a toll on the airframe so the tail was lengthened and the wooden 3-bladed propeller was replaced by a 4-bladed constant speed metal propeller to help deal with the torque and power the engine provided. However, this propeller was frustrating to work with as the 12.7 mm Ho-103's proved to be quite difficult to synchronize. Two Ho-5 20 mm cannons were mounted in the wings to remedy the weak armaments of the Ki-44 and Ki-43, and the small size of the cannon allowed them to be mounted in the nose later on in its life.
"Heinkel He 51 C-1 single-engine fighter/light ground-attack aircraft
 
  
The combat début of the He 51 fighter took place in 1936 during the Spanish Civil War. Heinkel fighters were flown both by Spanish Nationalists, including Joaquin Garcia-Morato, the best ace of the Spanish War, and by German fighter pilots of the famous Condor Legion.
+
The new aircraft first took flight in 1943 and proved to be better than almost any aircraft in service with the Japanese at the time, reaching nearly 500 mph/800 kmh in a dive and 387 mph at tree-top level, and was quickly approved for service under the designation "Ki-84 ''Hayate"''. However, the increasing deterioration of the Japanese economy and depletion of resources resulted in many defects, with the engine providing less power than intended and the landing gear being susceptible to breaking on landing due to the lack of steel to properly maintain them. Japan was also having manpower problems that resulted in a lack of skilled pilots that could bring out the best in the aircraft.
  
In November 1936, General Franco's pilots and German volunteers met in the air for the first time with Polikarpov I-15 fighters supplied to the Republicans by the Soviet government. The appearance of the Soviet planes was a shock for the German pilots, who had believed that their He 51B was superior to foreign fighters in every respect. The superiority of the I-15 over the He 51 in speed, manoeuvrability, and rate of climb was indisputable. Although the Soviet fighter's four PV-1 machine guns had a slower rate of fire, they provided fire superiority over the German's two MG 17s. In addition, the He 51's magazine capacity was three times less.
+
Regardless of these problems, the Ki-84 proved to be an excellent aircraft that gained the respect of both its pilots and enemies, with USA stating that it was likely the best aircraft Japan had made and Japanese pilots found it relatively easy to fly, maintain and control.
 
 
When the experience of the He 51's combat employment in Spain showed the complete superiority of the Soviet fighters, it was decided to use the plane as a ground-attack aircraft to provide direct air support to ground forces.
 
 
 
The He 51 C-1 variant was launched into full-scale production. These aircraft were notable for their bomb racks, which were able to suspend six 10 kg fragmentation bombs. The bomb racks were mounted under the lower wing panels.
 
 
 
He 51 fighters of early variants were modified by the troops on site, fitted to carry bombs. The experience of combat with the He 51 during strike missions against ground targets had an enormous influence on the future development of the Luftwaffe, particularly on its tactical deployment of the Hs 123 and Ju 87 dive bombers.
 
 
 
A combined total of 725 He 51 fighters were built. 135 aircraft of the ""A"", ""B"", and ""C"" variants were delivered to Spain. When the Civil War was over in April 1939, only 46 He 51s remained in good enough condition for flying.
 
 
 
Spanish He 51s served as light ground-attack aircraft and then as training planes until 1946."

Description

GarageImage Ki-84 otsu.jpg


The Ki-84 otsu Hayate is a rank IV Japanese fighter with a battle rating of 6.7 (AB), 5.7 (RB), and 6.0 (SB). It was introduced in Update 1.37.

General info

Flight performance

The Ki-84 Otsu is a very stable platform that can easily compete with its contemporaries at the tier. It has an excellent top speed and acceleration for a Japanese aircraft, but is still quite a bit lacking when compared to aircraft like the late 109's, Ta 152, Bearcat, P-51H, and the Griffon Spitfires. However, its most powerful trait is its excellent manoeuvrability. The Ki-84 will be able to outturn anything it faces with the usage of combat flaps that's not a Spitfire or Re.2005 (with the exception of other Japanese fighters like the A6M5). Overall it is an enjoyable aircraft to fly due to its excellent manoeuvrability, competitive top speed and acceleration, and smooth controls, but the pilot must take care at speeds above 630 km/h as the aircraft will stiffen up considerably.

Survivability and armour

  • 13 mm steel backrest
  • 6 mm steel headrest
  • 70 mm bulletproof windshield, sloped

Armaments

Offensive armament

Main article: Ho-5 (20 mm)

The Ki-84 otsu is armed with:

  • 2 x 20 mm Ho-5 cannons, nose-mounted (150 rpg = 300 total)
  • 2 x 20 mm Ho-5 cannons, wing-mounted (150 rpg = 300 total)

The Ho-5's are very volatile weapons when approached from a beginner's standpoint. Their reasonably high rate of fire combined with lower than average muzzle velocity and poor HE round makes it so that one must be fairly close to deal significant damage. Fortunately, they are quite accurate and do not jam as badly as its competitors such as the Hispano Mk.II/Mk.V and do not perform as badly as the Russian ShVAK. Your belt of choice should be Universal or Tracers, with Tracers dealing the most consistent damage and being easier to aim due to not having to deal with the velocity difference between the HE shell and the Tracer shell.

Suspended armament

The Ki-84 otsu can be outfitted with the following ordnance:

  • 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 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 and relatively lacklustre armament, although fairly 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
  • Solid roll rate at medium and low speeds

Cons:

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