Description

The ▃Ki-43-II Hayabusa is a premium Rank II American light fighter with a battle rating of 2.3 (AB) and 2.7 (RB/SB). It was introduced in Update 1.43.

The Ki-43-II Hayabusa was built from the ground up to be a very manoeuvrable turn fighter. It sacrifices any additional armament and armour for the ability to turn and climb. The aircraft was fitted with butterfly flaps (a type of combat flap) that drastically boost its ability to turn. Since the Hayabusa lacks any armour you will need to fly it with a defensive mindset. This aircraft is very comparable to the A6M series in the regards of handling and tactics.

Survivability and armour

Armaments

Offensive armament

The Ki-43-II (USA) is armed with:

• 2 x 12.7 mm Ho-103 machine gun, nose-mounted (250 rpg = 500 total)

Usage in battles

In all modes, the Ki-43 can perform both BnZ fighting and turnfighting with the correct opponent. It can easily accelerate to 500 kph in a dive while still having responsive controls. However its speed retention is quite poor and will loose lots of speed as soon as you level out. For turnfighting, you can out-turn most monoplane and almost all heavy fighters / attackers even without combat flaps deployed, but never turn with Spitfires and Zeros.

While having sufficient flight characteristics, the Ki-43 is extremely fragile and can get critically damaged by almost all guns. From the hard-hitting M2 Browning to the fast-firing MG 15, any gun can badly hurt the Ki-43 especially on the engine, fuel tanks, and pilot which can always lead to a later crash. Before attacking try to get an altitude advantage and perform deflection shots. To maximise the damage aim for their wings and engines, as the fuselage usually soaks up lots of bullets. Only fire when the bomber passes in front of your guns. This short window might seem inadequate to do anything... and it usually is, unfortunately. The slow velocity, light projectiles and low one-second burst mass usually guarantee no critical damage. However sometimes it only takes one bullet to set the target aflame, if you are lucky.

• In simulator, the Ki-43 is overall a decent plane. It has very forgiving characteristics such as good over-the-nose visibility, a clear bubble canopy without much framing and good backwards visibility. This increases your chance of spotting, tracking and / or dodging since you can see targets from almost every direction with ease (except the underside, of course). It is recommended to set keybind for moving your head vertically to make full use of the great forward vision in a dogfight. However, its wings are located directly below the cockpit meaning that you cannot see what is below your sides which can lead to you losing track of the enemy. You should get used to searching towards your 2, 4, 5, 7, 8, 10 o'clock, avoiding the wings.
• Note that when taking off the Ki-43 will shift severely to the left due to the propeller torque, so it is recommended to set keybind for left & right brakes to effectively control your direction on the runway. Using rudder alone will not work at low speed and you will either circle around or lose control and crash into nearby structures like tents / hangars.
• Landing is very beginner-friendly too. It is able to decelerate quickly while also having low stall speed, allowing you to quickly slow down and descent onto the runway. Takeoff & landing flaps do not lift up the nose a lot so you can easily remain overall parallel to the ground. It also performs great when braking as its nose will not usually dip into the ground, so you can keep braking until it fully stops (given that you deflect elevators fully upwards) which is vital for preparing the next fight quickly.
• It has very good handling at most speeds. It does not wobble a lot which is an advantage over the biplanes and early monoplane fighters, making it easier to smooth the aim. You should familiarise the shape of those that you should not turn with: the Spitfires have long, straight nose with an inline engine, rather large and elliptical wings. The Zeros have an overall cylindrical fuselage that merges into a pointy tail after the stabilisers, a radial engine and are usually painted white (early models). If you see them on your tail try outrunning them by diving at around -40 degrees. The Ki-43 still remains responsive handling at 500 km/h, but its speed retention is poor, meaning it will start to lose speed quickly and the enemy might catch up. If you are near a friendly airfield, great. If not, then hope for the best and run towards the friendly side. Don't forget to pitch up and down a little to mess up their aim, the early Spitfires and A6M only have a 60-round drum per cannon which will run out fairly fast. The leftover 7.7 mm machine guns will not be as destructive but still might destroy you.
• It will be very challenging when facing against the Japanese Ki-43, as both of you have the same characteristics. You cannot outrun each other and cannot out-turn each other, so the fight will be a combination of various maneuvers and techniques, and of course, the pilot's skills. Note that the Ki-43 has similar appearance as the Ki-44 and can be misjudged as a Ki-44 or a Zero. Comparing to the Ki-43, the Ki-44 has a slightly bigger engine and the canopy is shifted backwards, while the Zero has a very framy cockpit and usually a fully black nose. They all turn good and have fast dive accelerations.
• When it comes to intercepting ground pounders or bombers, the Ki-43 generally performs poorly since the targets are all quite robust against your weak guns. Some examples are the IL-2 which is commonly seen in sim. It can get mistakenly seen as other aircraft from a distance due to its common appearance. But up close you will see two bomb-like structures underneath its wings and triangular stabilisers with rounded tips. The early IL-2s have no defensive guns so it is safe to sit behind and carefully aim. They are heavily armored in the cockpit and engine so avoid aiming at these areas. Instead target the tail to hope for disabling their tali control. The late IL-2s, however, have a rear-facing Berezin UB which is something you definitely want to avoid. Perform deflection shots or just disengage.
