The most plausible manner to use this aircraft is in the Boom & Zoom role, given its fast speed in a dive. In addition, the nose-mounted .50 calibre can help you preform certain attacks a P-40E pilot could dream of doing. However, there are certain methods to using the plane, as it is an earlier iteration of the H-81A-2 is a P-40.

However, there are certain methods to using the plane, as it is an earlier iteration of the H-81A-2 is a P-40.
  
The first method is to climb to altitude, and try to intercept enemy attackers and bombers. This tends to play in favor of the H-81A-2, due to its excellent top speed of 528 kph (328 mph) at 3,800 meters (12,467 feet.) That being said though, you are inhibited by its relatively slow rate of climb of only 10 meters/second (32 feet/second.) On the contrary, once you reach altitude, Boom & Zoom as much as you want against bombers, as your high dive speed will make it difficult for most gunners to target you. In addition, you have a nice turn speed of 21 seconds, which can allow you to snap over on some opponents with relative impunity. If you do find yourself fighting in the vertical, flaps will also be of use to you, as they do have a decent speed tolerance before they snap off.

In Ground RB, you are a nice ground pounder as there is a bombload of 1x 500lb bomb plus 2x .50 cals in the nose. When you spot an enemy ground unit, it is best to climb to around 1500m before diving at it. This way you have quite some time to distinguish your target as you dive down, and the speed gathered will also protect you. Recommended diving angle is around 30-70 degrees. Once you speed passes 520 kph and the target fills up the reticle, pull the reticle right above the top of the target and release the bomb, it will land very close if not directly hit the target. If you cannot dive that fast, aim higher above the target before releasing bomb. After dropping the bomb, the nose-mounted .50 cals are good for strafing tanks' roof armour. Now you want to dive steeper for the bullets to pierce through. When diving, cut throttle and slow down to give yourself a long window to aim and burst, you must fire from a rather far distance since you need some time to pull up from the near-vertical dive. The 12.7mm AP rounds are good at penetrating roof armour and knocking out crew/modules, giving you kills or assists.

; Simulator Battles

 +
* In Simulator, the H-81 has great potential but is not very friendly to beginners. Its advantages include decent dive and level speed, a surprisingly good turn rate, and adequate visibility over the nose unlike the similar P-40. However what make this plane hard to master is that its weapons of machine guns require landing continuous hits on an aircraft in order to damage/destroy it, yet most players will struggle to align even one pass. It also suffers from severe wobbling, resulting in the gunsight swinging around when trying to adjust the aim, which can make the player miss their chance to fire. Other drawbacks include the limited visibility due to numerous canopy frames and a razorback design, and the engine tends to slowly overheat at 100% throttle. WEP cannot be used for more than half a minute, as it will also heat up the engine quickly.
 +
* Before entering a battle, it is recommended to set keybinds for trimming on all axis and vertical head movements to improve the forward visibility a bit. Like the P-40, the H-81 is nose-heavy so trim the elevator for around +4% depending on your speed. Take at least 30 minutes of fuel. Recommended convergence lies between 250-500 m.
 +
* For dogfighting, because almost all aerial battles in Sim occurs at below 3,000 m, the P-40 can easily climb to this altitude and gather up lots of speed before engaging a battle. The tactic is similar to the RB one above, which is to keep speed and boom and zoom. If, unfortunately, you find yourself being chased on your six and you don't know how to do any defensive manoeuvres, do a large, smooth turn towards the nearest friendly airfield to avoid bleeding too much speed. Then shallow-dive towards your airfield. The P-40 can quite easily outrun opponents like the [[A6M (Family)|A6M]] or [[I-15 (Family)|I-15]], but struggles to outrun [[Bf 109 (Family)|Bf 109 F/Gs]], [[Fw 190 (Family)|Fw 190 A]] or other [[P-40 (Family)|P-40s]]. Another way of disengaging is to do a sudden Split-S to dodge under the chaser. Average Sim players will now try and see where you went, if not immediately losing track of you. You can then run for your airfield or shallow climb for another attack.
 +
* When intercepting player bombers or AI bombers/attackers/reconnaissance aircraft, it is best to get an altitude advantage of at least 800 m before engaging. This way, you can not only BnZ the target which is your common tactic, you also get enough time to smooth the aim as you dive, helping you to score accurate hits. After a pass do not try and stay at their tail and keep shooting, disengage immediately and zoom away, preparing for another pass if needed. Chasing behind a bomber makes yourself pretty much stationary for the tail gunners, and you will be showered with bullets. The huge engine & cooling systems of the H-81 will usually get damaged which is fatal if you are far from friendly airfield.

<!--Some concerning vehicles to worry about if playing this plane. (i.e. Japanese fighters will out turn you)-->
Perhaps the biggest threat comes from facing any Japanese plane at this battle rating. They can turn so much faster than you as to bleed your speed and energy to the point of stalling out. The greatest threats come from the Ki-44s and the A6M2-N. In addition, the Ki-43 has significantly greater maneuverability than you. The vast majority of these planes have guns similar in caliber to a .50 Cal, which means that they have the firepower to dispatch you at a fairly fast rate.

The vast majority of these planes have guns similar in calibre to a .50 Cal, which means that they have the firepower to dispatch you at a fairly fast rate. The H6K & H8K are  very spacious flying boats, being most threatening in Simulator since it is much harder for the interceptor to aim precisely like in realistic battles. They have fairly deadly 20 mm defensive cannons facing backwards, so avoid tailing them from their six unless the gunner is unconscious. Engage from their sides or high six and aim for the wings. Your 2 x 12.7 mm + 4 x 7.62 mm MGs will cripple its wing structures easily or set it aflame if you are lucky. Don not engage if you have no altitude advantage.
  
In terms of the British, any Spitfire or Hurricane will out-turn you. While they do not have as heavy of armament as you do, the shear rate of fire from the .308s can light up exposed ares of the plane, or even score a pilot kill. While it is mostly unlikely, the Spitfire Mk. IIb not only boasts maneuverability, but also two 20 mm Hispano cannons, which can tear you to bits. In addition, almost all British fighters can out-climb you, which leaves you at a disadvantage in energy.

The Germans have the most planes that can give you a problem, due to the vast majority of them having 20 mm cannons. Most notably are aircraft like the Bf-110 and the Bf-109 E-3. You also do have to worry about aircraft like the Bf-109 F-1, which has a 20 mm cannon in the propeller hub. While it is unlikely, you may also face the Fw-190 A-1. Most German planes will have a significantly better climb rate than you and be able to energy fight you more efficiently. As mentioned earlier, most German planes boast much heavier firepower than you, which renders you at a disadvantage in punching power.

Most Russian planes will also give you a run for your money. Almost all of the Russian planes boast only nose-mounted weaponry, giving them a significant advantage over most allied planes. The most common enemies to worry about are any plane with the prefix "Yak." Perhaps the most common cause of US teams being defeated by the Russians, is the fact that they head on an IL-2. '''Never''' under any circumstance head on an IL-2.

In Ground RB, avoid SPAAs at all cost. If you are the only aircraft up and there are SPAAs firing towards you, get away from them. Although the H-81 is armoured by steel armour plates and bulletproof glass, it is still very vulnerable to 12.7mm/20mm/37mm shells. Direct hits will usually damage your huge cooling system which can result in a crash. However, if a teammate plane gets the attention of enemy SPAA, you can sneak up on them. At this BR, common SPAAs include M16, Flakpanzer 38 and Sd.Kfz. 6/2.

As mentioned earlier, the H-81A-2 has nose-mounted .50 cals, which can make short work of almost any fighter at battle rating 2.3. The aircraft also has a tighter turning time than the P-40E, which can give a H-81A-2 pilot a small advantage. If a H-81A-2 finds its way onto your tail, try to make the pilot over-shoot or bleed energy. The cockpit, while having more protection than an open top and a bubble canopy, is still a fairly vulnerable spot, so pilot snipes aren't uncommon.

Heads up for German and Russian pilots! While aircraft like the Bf-110, LaGG-3 and the Yaks have nose-mounted weaponry, an experienced H-81A-2 player can still make you pay dearly in a head-on. If you find yourself in a head on with a H-81A-2, fire a short burst, then hit the deck to avoid being hit by return fire. This is especially true with the Russians due to their wooden air frame.

The H-81A-2 is one of the export versions given to the ROC through the American Volunteer Groups sent to China. The volunteer force was sent by US president Franklin Roosevelt to deter Japanese aggression during the Second Sino-Japanese War. At the time these aircraft were a relief for the Chinese aid as the aircraft they were using at the time, primarily I-16s and I-15s, did not compete well against the Japanese air force. The only unit of these volunteer groups to actually see combat against the Japanese forces was the 1st AVG, otherwise known as the "Flying Tigers".

Usage in battles

The most plausible manner to use this aircraft is in the Boom & Zoom role, given its fast speed in a dive. In addition, the nose-mounted .50 calibre can help you preform certain attacks a P-40E pilot could dream of doing. However, there are certain methods to using the plane, as it is an earlier iteration of the H-81A-2 is a P-40.

The first method is to climb to altitude, and try to intercept enemy attackers and bombers. This tends to play in favour of the H-81A-2, due to its excellent top speed of 528 kph (328 mph) at 3,800 meters (12,467 feet.) That being said though, you are inhibited by its relatively slow rate of climb of only 10 meters/second (32 feet/second). On the contrary, once you reach altitude, Boom & Zoom as much as you want against bombers, as your high dive speed will make it difficult for most gunners to target you. In addition, you have a nice turn speed of 21 seconds, which can allow you to snap over on some opponents with relative impunity. If you do find yourself fighting in the vertical, flaps will also be of use to you, as they do have a decent speed tolerance before they snap off.

In Ground RB, you are a nice ground pounder as there is a bombload of 1x 500lb bomb plus 2x .50 cals in the nose. When you spot an enemy ground unit, it is best to climb to around 1500m before diving at it. This way you have quite some time to distinguish your target as you dive down, and the speed gathered will also protect you. Recommended diving angle is around 30-70 degrees. Once you speed passes 520 kph and the target fills up the reticle, pull the reticle right above the top of the target and release the bomb, it will land very close if not directly hit the target. If you cannot dive that fast, aim higher above the target before releasing bomb. After dropping the bomb, the nose-mounted .50 cals are good for strafing tanks' roof armour. Now you want to dive steeper for the bullets to pierce through. When diving, cut throttle and slow down to give yourself a long window to aim and burst, you must fire from a rather far distance since you need some time to pull up from the near-vertical dive. The 12.7mm AP rounds are good at penetrating roof armour and knocking out crew/modules, giving you kills or assists.

Simulator Battles
  • In Simulator, the H-81 has great potential but is not very friendly to beginners. Its advantages include decent dive and level speed, a surprisingly good turn rate, and adequate visibility over the nose unlike the similar P-40. However what make this plane hard to master is that its weapons of machine guns require landing continuous hits on an aircraft in order to damage/destroy it, yet most players will struggle to align even one pass. It also suffers from severe wobbling, resulting in the gunsight swinging around when trying to adjust the aim, which can make the player miss their chance to fire. Other drawbacks include the limited visibility due to numerous canopy frames and a razorback design, and the engine tends to slowly overheat at 100% throttle. WEP cannot be used for more than half a minute, as it will also heat up the engine quickly.
  • Before entering a battle, it is recommended to set keybinds for trimming on all axis and vertical head movements to improve the forward visibility a bit. Like the P-40, the H-81 is nose-heavy so trim the elevator for around +4% depending on your speed. Take at least 30 minutes of fuel. Recommended convergence lies between 250-500 m.
  • For dogfighting, because almost all aerial battles in Sim occurs at below 3,000 m, the P-40 can easily climb to this altitude and gather up lots of speed before engaging a battle. The tactic is similar to the RB one above, which is to keep speed and boom and zoom. If, unfortunately, you find yourself being chased on your six and you don't know how to do any defensive manoeuvres, do a large, smooth turn towards the nearest friendly airfield to avoid bleeding too much speed. Then shallow-dive towards your airfield. The P-40 can quite easily outrun opponents like the A6M or I-15, but struggles to outrun Bf 109 F/Gs, Fw 190 A or other P-40s. Another way of disengaging is to do a sudden Split-S to dodge under the chaser. Average Sim players will now try and see where you went, if not immediately losing track of you. You can then run for your airfield or shallow climb for another attack.
  • When intercepting player bombers or AI bombers/attackers/reconnaissance aircraft, it is best to get an altitude advantage of at least 800 m before engaging. This way, you can not only BnZ the target which is your common tactic, you also get enough time to smooth the aim as you dive, helping you to score accurate hits. After a pass do not try and stay at their tail and keep shooting, disengage immediately and zoom away, preparing for another pass if needed. Chasing behind a bomber makes yourself pretty much stationary for the tail gunners, and you will be showered with bullets. The huge engine & cooling systems of the H-81 will usually get damaged which is fatal if you are far from friendly airfield.

Specific enemies worth noting

Perhaps the biggest threat comes from facing any Japanese plane at this battle rating. They can turn so much faster than you as to bleed your speed and energy to the point of stalling out. The greatest threats come from the Ki-44s and the A6M2-N. In addition, the Ki-43 has significantly greater manoeuvrability than you. The vast majority of these planes have guns similar in calibre to a .50 Cal, which means that they have the firepower to dispatch you at a fairly fast rate. The H6K & H8K are very spacious flying boats, being most threatening in Simulator since it is much harder for the interceptor to aim precisely like in realistic battles. They have fairly deadly 20 mm defensive cannons facing backwards, so avoid tailing them from their six unless the gunner is unconscious. Engage from their sides or high six and aim for the wings. Your 2 x 12.7 mm + 4 x 7.62 mm MGs will cripple its wing structures easily or set it aflame if you are lucky. Don not engage if you have no altitude advantage.

In terms of the British, any Spitfire or Hurricane will out-turn you. While they do not have as heavy of armament as you do, the shear rate of fire from the .308s can light up exposed ares of the plane, or even score a pilot kill. While it is mostly unlikely, the Spitfire Mk. IIb not only boasts manoeuvrability, but also two 20 mm Hispano cannons, which can tear you to bits. In addition, almost all British fighters can out-climb you, which leaves you at a disadvantage in energy.

The Germans have the most planes that can give you a problem, due to the vast majority of them having 20 mm cannons. Most notably are aircraft like the Bf-110 and the Bf-109 E-3. You also do have to worry about aircraft like the Bf-109 F-1, which has a 20 mm cannon in the propeller hub. While it is unlikely, you may also face the Fw-190 A-1. Most German planes will have a significantly better climb rate than you and be able to energy fight you more efficiently. As mentioned earlier, most German planes boast much heavier firepower than you, which renders you at a disadvantage in punching power.

Most Russian planes will also give you a run for your money. Almost all of the Russian planes boast only nose-mounted weaponry, giving them a significant advantage over most allied planes. The most common enemies to worry about are any plane with the prefix "Yak". Perhaps the most common cause of US teams being defeated by the Russians, is the fact that they head on an IL-2. Never under any circumstance head on an IL-2.

In Ground RB, avoid SPAAs at all cost. If you are the only aircraft up and there are SPAAs firing towards you, get away from them. Although the H-81 is armoured by steel armour plates and bulletproof glass, it is still very vulnerable to 12.7mm/20mm/37mm shells. Direct hits will usually damage your huge cooling system which can result in a crash. However, if a teammate plane gets the attention of enemy SPAA, you can sneak up on them. At this BR, common SPAAs include M16, Flakpanzer 38 and Sd.Kfz. 6/2.

Counter-tactics

As mentioned earlier, the H-81A-2 has nose-mounted .50 cals, which can make short work of almost any fighter at battle rating 2.3. The aircraft also has a tighter turning time than the P-40E, which can give a H-81A-2 pilot a small advantage. If a H-81A-2 finds its way onto your tail, try to make the pilot over-shoot or bleed energy. The cockpit, while having more protection than an open top and a bubble canopy, is still a fairly vulnerable spot, so pilot snipes aren't uncommon.

Heads up for German and Russian pilots! While aircraft like the Bf-110, LaGG-3 and the Yaks have nose-mounted weaponry, an experienced H-81A-2 player can still make you pay dearly in a head-on. If you find yourself in a head on with a H-81A-2, fire a short burst, then hit the deck to avoid being hit by return fire. This is especially true with the Russians due to their wooden air frame.

Pros and cons

Pros:

  • Good firepower with plenty of ammo
  • Good manoeuvrability
  • Good rate of climb for the rank
  • High top speed for its rank
  • Fast dive speed and dive acceleration
  • Good durability
  • Significantly better over-the-nose visibility than the identical P-40, giving it a huge advantage in Simulator dogfights
  • One 500 lb bomb allows it to attack tank in ground RB
  • It is a premium = more research points and Silver Lions
  • .50 cals are nose mounted, concentrating their firepower

Cons:

  • Turn fighting with Japanese planes is not advised
  • Heavy weight and weak engine results in very poor energy retention. Will lose all the speed & altitude after around 2 BnZ passes
  • Engine overheats fast while using WEP, limiting its power output
  • Rudder locks up past 520 kph
  • Somewhat long takeoff run
  • .30 cals may struggle to do effective damage once the ammo for the .50 cals runs out
  • Engine will slowly overheat if cowling/cooling systems are damaged
  • Only one payload option of a single 500lb bomb
  • Numerous canopy frames and a razorback severely limit the pilot's all-round and backwards view in Simulator
