Interesting turn times and radius from Soviet sources

There is really so much difference between VVS-Tsagi and AH2 turning radius?

Off Topic: I'd like to see the same banning/censoring attitude towards the picking crowd.

 Yup... and I'm a bit confident in the objectivity of my testings, too.

 But like gripen said, I'm not sure what kind of condtionss the Soviets used to test the turn radius. If I know it, perhaps I can do a few more quick testings with matching conditions to offer more accurate comparison... (if I get off my lazy butt, that is)

 So what exactly was the conditions the Russians used in the mentioned testings anyway? Anybody know?

Full up weight typically..............well they took off at that weight.


eg turn trials on 3 gun La 7 #38100869 were at 3310 kg take off weight.

at 1000m Mil power (1000mmpt @ 2400rpm)

Speed 320>340Km/h
Turn time> 21 secs@ 305-335m
Bank angle >71

a 2 gun model La7 serial No.452132-76 weighing in at 3240 kg

Speed 340
Turn time>19.5L/18.5R

No radius or  bank angle given for that trial

Yea. the P-63's had a 37mm in the nose, that was an improved version of the 37mm in the P-39.  IIRC, it jammed less and had more ammo.  It could also pack 2-4 .50's, IIRC.  I haven't really looked at any of my books in a while.  I do remember that the P-63 had a .50 under each wing in a "gondola" type arrangement, and that the Soviets usually took those off.  So probably 1x37mm, 2x.50 would be standard.

Any idea what the ROF was for it? My buddy has a cool book with all the equipment the U.S. used in WW2 and it has detailed info on all the weapons.  I need to go steal it:D
