incorrect historic model of Ro-57

[Flaky_9999 37]

The Ro.57 was preceded by another twin engine fighter design, the Ro.53, which never entered production. The Ro.57 consisted of an all-metal, semi-monocoque fuselage with a steel skeleton and Duralumin structure. The wings were also Duralumin. It was powered by two 840 hp (630 kW) Fiat A.74 radial engines giving a maximum speed of 516 km/h, which in 1939 was faster than that of the main Italian fighter, the Macchi C.200 (504 km/h).

After testing at Guidonia it was proposed by IMAM for use as a dive bomber. This transformation, which involved the addition of dive brakes, provision for 500 kg bombs and an improved forward firing armament (adding two 20 mm cannon), ^[3] took time and delayed production. The resulting aircraft was designated the Ro.57bis. Performance dropped to 457 km/h maximum speed and to 350 km/h at cruise speed. The Ro.57bis was ordered into production in 1942 and entered service with the 97° Gruppo in 1943. About 50–60 aircraft were delivered. ^[4]

It is said that the Ro.57 could have been the long range interceptor that Italy lacked throughout the war. It proved to be too costly for the limited weapons it carried and it never was assigned a clear role^{[ citation needed ]}. A better-armed version with more powerful engines was developed as the Ro.58.

LoL wikipedia

[Hardmoor 2,196]

when you copy EVERYTHING

[doflite 100]

look at the sources that Wikipedia lists, check if they agree, then tell gaijin what to do.

[Mora__ 29]

What we got has Hispano cannons as oppised to Mauser. BR 2.7 would be fine MG 151/20, but with Hispanos it should be 2.0. The plane is an absolute dog.

thanks wiki for making my life hell

 

as i said under videos on yt and on the discords, all of the actual sources on the plane agree that the Quadriarma had hispano 404 20mm cannons. Not only that, but you can clearly see they are hispanos by looking at the muzzle break in the photographs:

 

 

The production run went as follow:

first the normal 57 with 2x12.7mm bredas and no bombs

second the bis, still with just 2x12.7 but with an airbrake, bombs and some minor mods

lastly some (1, 2?) bis were converted to quadriarma by adding the two hispano cannons and removing a small fuel tank in the nose
