This is an old topic I know, but according to several charts posted in this forum the P-40 had a superior roll rate comapared to the P-39. The current P-39 roll more resembles the P-63's. Will the P-40 and P-39 roll rates remain untouched?

Thought I'd bump this. I'd like to get some answers. Are there any sources that can back up the high rollrate of the P-39 in FB?

yea is very interesting how roll rate had P-39? Have any info about these. If we speak about FM in my opinion now in FB is not exacly what i expect. As i read P-39 required carefully flight because stall/spin. Now you can fly cobra and you don't care to much about spin/stall. P-40 is hardly to flight than P-39 like should'nt be http://ubbxforums.ubi.com/infopop/emoticons/icon_frown.gif
Oleg if you read these topic please fix these arcade FM of Cobra.

Take the hint guys, Game bugs only please.

Though I would hardly consider myself an expert on the plane type, I believe I've read that the final bloks of P-39s [Q10] were re-designated as P-63s after production.

I have not seen any roll rate numbers for the specific model P-39s we fly in FB as yet. Lots of data on pre-N models, but one consistent thing that keeps coming up in accounts is that the 39 took several revisions to improve its performance and get the 'bugs' out.

Clint - your wrong about the p-63 - completely different animal - laminar flow and all that.

As for the 39s roll - look at the differences in revisions of the p40 for comparison - there can be huge differences in various models while they look the same on the outside.

I would like to see some data on the vvs variants.

Hi Nagual,

As I mentioned - just a hazy recollection of reading this:



P-39Q-10-BE (Model 26Q-10): Internal fuel capacity rose to 100 Imp gallons and armor weight went to 227.1 pounds. The throttle was linked to the propeller settings to provide automatic adjustments. There was additional winterization of the oil system, and there were rubber engine mounts installed. The first P-39Q-10-BEs were delivered to the USAAF by the end of July 1943. A total of 705 examples were built, but 995 more that were assigned serial numbers 42-21251/22245 were actually completed as P-63E-1 Kingcobras.

Well I'll be darned! 63 is a reengineered bird - different wing, tail, motor etc. Had excellent climb - outdid late war (la7,9,yak3,9u) types in horizontal maneuvers - according to vvs tests! Very fast on the deck - but good up high too..


On the p39s spin - it is very much there. I did a test the other night - went into a a slowish turn - 350 k or less - and hit full right rudder - boom! very very nasty flat spin - spun down 2500 meters before I recovered - at 500 - and I'm pretty good in the 39. You have to make a mistake to enter a spin - but it's there and it is very nasty. I had to pull every trick I had out to go with it. Simply reversing rudder - which will work in a lesser spin and used to allways work in the 39 - even back in FB - does not help - going with the spin caused it to accelerate dramatically. I had to play with flaps, rudder and throttle all together to get out.

I flew the P-39N last night on many diff missions

it clims VERY well, it rolls VERY well, it is not THAT unstable...right now I think its one of the best pre-1944 plane of the game, with A5 and La5fn

was it THAT good?
Porkryshkin thought it was good...but I mean, currently it is awesome...too much imo

The P-39 has been Uber since IL-2 FB v1.0, don't know, maybe to compensate for under preforming P-47 and P-51................./i/smilies/16x16_smiley-sad.gif
