Description

The He 51 B-1 is a rank I German fighter with a battle rating of 1.0 (AB/RB/SB). It has been in the game since the start of the Open Beta Test prior to Update 1.27.

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 He 51 B-1. 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 He 51 B-1 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.

Like many biplanes before and contemporaries of the He 51 B-1, 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.

Armaments

Offensive armament

Weapon 12 x 7.92 mm MG 17 machine gun

Ammunition1 000 rounds

Fire rate1 200 shots/min

The He 51 B-1 is armed with:

• 2 x 7.92 mm MG 17 machine guns, nose-mounted (500 rpg = 1,000 total)

When comparing offensive armament between reserve aircraft, the He 51 B-1 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 He 51 B-1 only sported two 7.92 mm machine guns with a few options of ammunition types available for use.

Some of the reserve aircraft the He 51 B-1 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 He 51 B-1 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.

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.

Usage in battles

In Simulator, the He 51 is overall not an ideal plane to fly. Its advantages include the pair of fast-firing 7.92 mm MGs, allowing you to put enough bullets into the opponent when led correctly. It also has very stable handling (will not spin out as much) and great side and rear views with nothing at all to obstruct your view. You can even see your whole tail. At last, the He 51 has good rate of climb in comparison to most other equivalent battle rating aircraft allowing it to play the energy tactic well. This is good because the He 51 is a slow bird and has trouble catching virtually any other plane in level flight, but given its slow speed, it also sports an exceptional turn radius allowing it to turn a death-spiral into a turkey shoot. However, its disadvantages are that the front view offers an extremely restricted panorama and it is difficult to anticipate targets with a thick wing in your face, which will very often cause you to lose track of your target. As with all biplanes, this characteristic tends to dissuade its use in SB. Its good manoeuvrability is also countered by every other reserve aircraft as they can turn equally well. In addition it can get quite wobbly when manoeuvring at low speeds which can cause you to miss the shot. The MGs also have a really low one second burst mass, so to effectively damage an opponent you need to constantly lead correctly, which is not always possible. Therefore, the He 51 can only perform dogfights with other biplanes, and ground pounding.

Bring at least 30 minutes of fuel for prolonged patrolling and fighting, and set the convergence to around 300 m. When taking off, the He 51 will shift severely to the left so you need to set separate keybind for left and right brakes to counter the torque. Be careful when the plane is just lifting off and you want to cancel the roll caused by the torque, the He 51 responds very sensitively in the roll axis, thus too much aileron deflection will over-roll, striking a wing into the ground.

For dogfighting, it is crucial to know what the target is. If the opponent is a biplane, combine your turn rate, combat/takeoff flaps and decent climb rate to gradually get an advantage and get onto its tail. Now you want to be more careful to not lose track of it as your upper wing is very annoying. Smooth the aim to extend your firing window as much as possible, to utilise the great rate of fire and avoid the low burst mass. Most biplanes cannot survive too many hits. However if it is a monoplane, try to lure it into a turnfight. If an energy fighter (e.g. Yak-1) uses BnZ tactic on you, do what you do in Arcade/Realistic: roll to one side and pull under it to avoid the dive and to dodge under its belly. Now average Sim players tend to struggle to trace you, if not immediately losing track of you. Repeat this until they lose patience and start to turn with you. However, if you see a plane with an I-15's short and fat fuselage, a flat radial engine and triangular stabilisers located right after the low-mounted mono wings, consider disengaging. The I-16 is faster than you, turns equally well and can cripple your fragile He 51 even with 2 x MGs. If an I-16 is on your tail, a tactic to counter it is to utilise your stableness. Deflect both your ailerons and elevators for around 70% to get into a barrel roll. If the I-16 is to follow and cut inside your roll, it is super likely to enter a flatspin due to its instability in manoeuvres. Perform the barrel roll tighter and tighter until the I-16 loses control and spins, then turn around and shoot. Or, do simple flat turns but turn tightly, a tight-turning I-16 is also prone to enter flatspins, however this is at risk of getting shot before it loses control.

For ground pounding, your targets are trucks, AAA and howitzers. First you need some separation between you and the target so you have enough time to stabilise the plane. The He 51 can get quite wobbly. Dive at it and first stabilise the plane so the gunsight stays overall still at the target. Then, once the target fills out around 1/6 of the gunsight, open fire. If your aim is accurate you can destroy one target in a single pass. However, each MG only has 500 rounds and their rate of fire is pretty fast, so control the trigger to save some ammo for any unexpected dogfights.

Landing is easy thanks to the low stall speed and lovely handling. Line up and approach the airstrip at treetop, decrease speed to at most 200 km/h and deploy combat, takeoff and landing flaps in order. The touchdown speed should be no more than 140 km/h to avoid bouncing up. Release brakes immediately as soon as the nose starts dipping down to avoid propeller strike.

Enemies worth noting

• Su-2 (Family): given your weak firepower, even an average attacker will appear to be super robust. The Su-2 has tough airframes that will not easily get damaged by your MGs and a rear facing, rapid-firing ShKAS that can easily cripple you. Think twice before engaging. Its appearance is quite common, the most noticeable features can be the cockpit & turret that roughly resemble a TBF's, a protruding chin, olive green camo and a large and tipped spinner.

History

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 Siegfried 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.

Heinkel He 51 B-1 single-engine fighter In the spring of 1935, a new fighter variant, the He 51 B-1, was launched into production. It differed from the "A" version in that it had reinforced twin braces and a fuselage rack to mount a 170-litre external fuel tank. By the spring of 1936, the new version replaced the He 51 A-1 on the production lines. Heinkels were the main Luftwaffe fighters at the time. The He 51 ended up at the centre of a boisterous propaganda campaign developed by the Reich Ministry of Public Enlightenment and Propaganda around the reviving Luftwaffe. However, the He 51 was not commercially successful on the foreign market. In 1935, after they failed to obtain a licence for the Polish P.24 monoplane fighter, the Hungarian government turned to Heinkel with a request to consider the possibility of producing the He 51 with a French 850 hp Gnome-Rhone 14K engine. Despite the powerful engine, this variant's test results did not satisfy the Hungarians, and they chose to purchase Italian CR.42 fighters instead of Heinkels. The He 51's career as the main Luftwaffe fighter, meanwhile, started to decline. In January 1936, a series of training duels took place between the Ar 68, a new fighter by Arado Flugzeugwerke, and the He 51. The series was lost by the Heinkel fighter, as it was significantly inferior to its opponent in manoeuvrability, rate of climb, and maximum speed. As front-line fighter wings were being rearmed with new equipment, the He 51s were handed over to units intended to provide direct air support for ground forces. They did not stay there too long and were soon delivered to training units, where the He 51s were used for training fighter pilots throughout the entirety of World War II. At the end of the war, He 51s were occasionally used as light night bombers against Red Army units or for anti-guerrilla purposes. Their efficiency in this capacity was deemed unsatisfactory, and the He 51s did not win any fame as night bombers.
