What's Up With the Yak-9U?

[funked]

Jugs out turn it easily.  This shouldn't be should it?

[leonid]

Not in my experience.  In Tour 5, I killed 12 jugs in a Yak, only dying to them twice.  And those two deaths were when I was out of E, on the deck, and got bounced.

Well maybe I just suck!

you suck funked

Recalibrate your stuff. In a Jug I don't like to see a Yak incoming to me.

Actually Funked, I think your right.

The turn rates of the Yak (especially to the right) seem very unimpressive and its prone to snaprolls.

Even using the worst of the two data points we have for this plane, it should be doing a turn time of 20 seconds.

Anyone timed it yet?

I find it easy to stay on the tail of a P47 in the Yak9.  I think that airspeed has alot to do with it, Jugs usually try to either dive away or at least perform evasive maneuvers while diving, so that lets the Yak9 build up some speed.

They are very close.  I found the yak to out-turn the 47 by about 1 second at a similar speed (150 mph).  The yak turns to the right better than the left, it seems and the P-47 turned better to the left.  The difference was 2 seconds for right hand turn (28s vs 30s)

Interesting Wells.

Even the "production" Yak-9U had a published turn time of 20 seconds, and if you give a 10%-15% "slowdown" factor (to match the fact that most other planes are 10%-15% slow on turn times according to the comments on Laz's turn thread) which comes out to a 23 second turn, thats still at least 5 seconds off.

That means the Yak is over 20% too slow in sustained turn rate to the right, probably slightly less to the left.

Without the adjustment factor that means an error of almost 29%.

Quite significant IMO.

Vermillion 50% fuel right?

[humble]

I was very suprised how mediocre the yak-9 seems to turn. I expected something on par with the 205 or G-6. It seems to be in between the hog and pony to me.

[Vermillion]

50% fuel ????

If your asking if that turn time number is for 50% fuel, not to my understanding.

It is quoted along with the other "production" performance numbers from Soviet Combat Aircraft of the Second World War, by Gordon and Khazanov, and these match the AH performance almost exactly.

And these numbers are for the standard 100% fuel (as far as I can tell). So I would assume the turn time performance number is for the same flight conditions (ie loadout) as for the max speed, max speed at altitude, climbrate, etc.

A good test is to see how the La-5fn compares in turn times within the game versus the published number. Since the La-5fn, like the Yak-9U,  otherwise matches the "production" performance numbers from the same book.

The La5fn's turn time is suppose to be 19 seconds to the left. Anyone measured it in the game?

Somebody told me the NII VVS stuff was done with 50% fuel.

Yak-9 seems like some aerobatics leaf to me, it can fly controlled 80-120mph and do some serious deck level maneuvers, lol.

But what I think here, is that P-47D is too 'light', at least that what I've tested in offline, its like a 4 ton fighter. (everyone who knows weight of P47, can say that P47 is heavier and also pretty heavy, not that light to fly  )

Btw. folks, I don't think Yak9 is a turn plane, I feel that it is more for maneuvers, like one'o'nines.

[funked]

You are right about the last bit - Yak-9U wingloading is 38 lb/ft^2, nothing special.  But a P-47 (47 lb/ft^2) should be easy meat in a turning battle.
