U35208026: I removed the part about having high wingloading. The Spitfire LF 9 does not have high wingloading. In fact it has very LOW wingloading compared to most of the other planes at its BR. That is why it turns so well.

-By March 1943, a new version of the Merlin engine had been developed. Designated the Merlin 66, it was even more powerful than the preceding 61 and 63 versions, was tuned for low-altitude operation, and featured a new injection-based carburettor instead of the float carburettor of previous models, completely resolving the fuel-flow issues during zero-G manoeuvres and inverted flight.

Spitfire F Mk IXs equipped with this new engine were designated '''LF (low-altitude fighter) Mk IX''' (also commonly referred to as the Spitfire Mk IXb). Production of the improved type completely replaced those equipped with older engines by late 1943, and the LF became the most produced variant of the Mk IX, with over 4,000 aircraft built.
-Introduced in [[Update 1.35]], the Spitfire LF Mk IX is very much a short range, point interceptor fighter and the stand out fighter in the mid Spitfire line-up. It features an exceptional rate of climb, whilst still retaining the manoeuvrability of its early lineage. The LF Mk IX is considered by many to be the perfect Spitfire due to its balanced all-round performance and impressive statistics. The last of the Merlin-engined Spitfires before progressing on to the Griffon-powered variants, it has the perfect balance of turning performance (second only to its Japanese counterparts) as well as its "Boom and Zoom" capability that becomes more possible with later model Spitfires. However, the LF Mk IX also reverts to the rather outmoded twin cannon and twin machine gun layout of its predecessors, which can result in rather meagre damage output compared to its contemporaries and opponents.

 Prop pitch: This should be set to 100% when climbing to utilize the aircraft's superior climb rate. This will come in handy both at the start of a match and during combat. However when in level flight or chasing another plane this can be set back as far to 70-80% to get a few more km/h.
-Radiator: as soon as you unlock the radiator module you can set this to 30% and leave it there for the entire match. On Sicily however you want to set it to 35-40% until you reach 6,000 m (19,685 ft)
+Radiator: The radiator can be set to around 30% when using 100% power, however setting the radiator to around 80% will allow you to use WEP for the entire game.
 Supercharger: Switching this at 2,000 m (6,561 ft) will give you quite a boost in performance and it will retain its climbrate up until 4,500 m, after it will suffer miserably but still climb better than almost every plane. Therefore the supercharger gears should be switched at 2 km (6,561 ft) altitude

+{{break}}
 The Supermarine Spitfire was a British single-engine, all-metal, low-wing monoplane fighter. While the Mk VII and Mk VIII variants was being designed, a Spitfire Mk III was tested in September 1941 with the new Rolls Royce 60 in the hopes of developing an interim fighter to use as a stop gap measure. The new Spitfire performed exceptionally well, and was rushed into production as the Mk IX. The Air Fighting Development Unit described the Mk IX as 'outstandingly better than the Mk V especially at heights above 20,000 feet' and even though it was not fitted with the modified control surfaces under development for the Mk VII and Mk VIII, the Mk IX was more than capable of meeting the Focke-Wulf FW190 on favourable terms. The Mk IX was fitted with the Type C 'universal' wing and originally carried the tried and tested combination of two 20mm cannon and four 0.303 inch machine guns, but in later versions the four 0.303 machine guns were replaced with two .50 calibre guns.
 A total of 5,665 Mk IX were produced and 262 more Mk Vs were converted to Mk IX. Intended as a transitional stop-gap measure for the Mk VII and Mk VIII, the variant remained in production until the end of the war, ultimately becoming the most mass-produced Spitfire version. This mark was also used as a fighter-bomber and as a reconnaissance aircraft. Further modifications were incorporated into the Mk IX throughout its service life, such as a gyroscopic gunsight, bubble canopy and modified engine intercooler. Widely considered to be the most capable fighter in the world at the time of its introduction, it would take the introduction of the Rolls Royce Griffon engine to push the Spitfire into its next stage of evolution.
