Best late biplane fighter

[Vincenzo]

I would start a comparison of latest biplane fighters, taking into only aircaft produced in series, i found this: Kawasaki Ki 10-II, Polikarpov I 153, Avia B 534 IV series, Fiat C.R. 42, Gloster Gladiator II, Grumman F3F-3.
If some have others craft for this i can add.

in weaponry for dogfight is best the fighters with 4 rifle caliber mgs, for intercepting is best more heavy guns also if only 2.

all this aircraft were considereer with high manuvrability, in horizontal speed the polikarpov is the best, in vertical maybe the avia

Some old threads on this:

This one is more comprehensive though including the Japanese, US, and Czech designs.


But for the ultimate biplane fighter it would probably be Canadian Car and Foundry FDB-1 - Wikipedia, the free encyclopedia (though only a prototype)

[Vincenzo]

Yes i know some of this, but there are many chats and political but few fighter comparison, and how you tell i add u.s., czechzlovak and japanee design

[Juha]

I-153

[SoD Stitch]

Could you add the Arado Ar 68E?

[Vincenzo]

please left out chats, choices must be motivated not by simpathy.

[Vincenzo]

sorry Ar 68E is clearly outclassed from this aircraft, all run over 60 km/h more fast or in other words it's of a previous generation

[Juha]

Why I-153
Finns used both Gladiators and I-153s and thought that I-153 was cleary better. British made an "unofficial" mock combat between Gladiator and CR.42 and the result was that CR. 42 was somewhat better.

Specs shows that I-153 was a bit faster and climbed clearly better than CR. 42. The 7,62mm mgs of I-153 had very high ROF.

I cannot say much on the other 3 but that Ki-10 had reputation of being very manoeuvrable but so was also I-153.

My choice has nothing to do with sympathy.

[Vincenzo]

so it's ok if you motivated at fitst now we've 3 post less in this topic, i'm sorry if i'm talking in not kind mode

[kool kitty89]

The modified Gladiator with uprated engine and 3-blade variable pitch prop (a fairly common field mod aparently, both by Finns and British in MTO) gave speed performance on par with the Cr.42 and slightly better maneuverability, and significantly better climb. Further improvement could be made by replacing the cowling with a more streamlined one. (similar to the Blenheim's) (and even more with 100 octane gasoline -producing nearly 1,000 hp at ~9,200 ft)

Often the modifications were made using peices taken directly from Blenheim.

The Finns made similar modifictions previously with their Gauntlets.

[Juha]

Hello kool kitty
the Gauntlet in the photo is powered by Leonidas engine, that's why it has more streamlined engine cowling. During it's reconstruction there was much debate on the engine choice. And the engine was almost it's doom, happened to see the crash or forced landing more exactly. It has been repaired back to flying condition.

[Mitya]

I-153

[kool kitty89]

I-153 had the best armaments overall.

[Vincenzo]

The 3 blade prop was the alone standard for Gladiator II, the perfomance are what indicated. kk89 you're sure of use of 100 octane on Gladiator?
Surely the soviet 12.7 mm are good weapons i'm not sure that 2 ubs mgs are best of 4 breda mgs.
for mitya and for all please i'm not interessed a list of post with a name of aircraft give motivation

[kool kitty89]

Don't know if 100 octane was ever used was used, but those ratings were for the Blenheim's Mercury XV engines.
