question:
  What exactly is the differnce between the D-25 and D-30 besides rocket loadout?
Oh, and besides the paint job.
Thanks,

Dive flaps And I heard it's slower.

Yak unstable? no way  
Stable plane at slow speeds and very fast too. (oo, seems faster than A-5)

I have flown Yak some, haven't died at all in it. (twice died, that was under vulch by 6 enemies and I was on real crazy mood, but i made it still over 1:1 K/D)
Something 20-25 kills in Yak so far on few flights.
P47 isn't big deal in a Yak.

I Find Yak very stable at slow speeds - nice to practice perfect landings with it.
It does also roll fast and not a bad diver either. (Fw190 shouldn't try to scissor Yak too much, definetly not at slow speeds)

niklas,
I don't get into sustained turn fights with anyone, if I can help it.  Even if I should win a stallfight, I'm nothing but meat on the table for anything else that shows up.  Surviving in AH requires that you think ahead to the next fight all the time.  But you knew that  

Also, I'm with Fishu in fighting 190s in scissors.  While the 190 can change direction really fast, the Yak can do so pretty fast too, then turn tighter.  Add to that the Yak's low speed handling, and its really a lose situation for a 190 to scissors with a Yak.  Best thing a 190 can do against a Yak is split ess, and hold onto alt.

Good points on some of the comparisons, but the jug is right on and well done for once in a flight sim.
I would rather see the F4U-c go away and fix the D model or add the F4U-4, I say this because the jug shouldn't spank the hog all over the sky like the other planes do.

the yak is capable of going from 300 to 60mph in a heartbeat too, so be prepared to overshoot if yer on its six


but watch the ultra slow stall, you could end up in a flat stall w no easy way to recover,

seems yak has slightly aft cg

P-47 engines are not the same as F4U engines.  There's this little turbo thingy...

That turbo thingy is not too effective until after 20k.

I should be more clear - P-47D-30 had 2600 hp using water injection as opposed to 2100-something for the F4U-1D.

Citabria,

I agree about the cg location.  There's this evasive maneuver Deft from WB taught me awhile ago.  It works fine on the Yak-9U, so long as you don't try it at too low a speed.  The resultant attitude of the aircraft, combined with the airspeed creates a flat spin where the axis of the stall spin seems to be about where the cockpit is.  Plus, the aft fuselage dips, leaving you with no options but to bail.

U guys make me laught... geez... kids... hehehe.

I can't wait for the FW-D9, so u 'I know everything' guys will squeak an another plane  and cry for the overmodelling.

Propeller is a bigge. The Hamilton active paddle-prop beats the 13ft Standard any day.
Like the comparison of the prototype P-38K with Actives vs the old Curtis blades.  

and the R-2800-8 in the F4U makes 600 less HP then the R-2800-59 in the P-47.

Most of the American planes have two-stage super chargers/turbos.

1st stage is 0-19k, although there is a large power loss after 10k that worsens till the second-stage kicks in at 19k. This goes for the Double-Wasps and the Packard/Merlins.
The Alisons were crappy because they lacked the second stage.

P-38 and the P-47 are exceptions to this loss in power however; the P-38's turbos are based on RPM and exhaust flow, as is the B-17, and the P-47's super charger is 3-4 times larger then the engine mounted ones on the other Double Wasps or the Packard/Merlins. It's sheer size allowed more effectiveness at lower alts and even in the dead zone between 14 and 19k. The standard super charger is about the size of a bell housing on your average truck (about 1' in diameter) while the P-47's is about the size of a washing machine (about 4' X 4')

And thus you get 600 more HP from the P-47 then from the the F4U.

It might be possible however, that some of the planes in AH have 3 stage super chargers but the preformence charts don't refelect it for the US planes.

Leonid. In this game Fw190A5 outturns Yak-9u in both left and right turns. It was checked in the Training arena. Both planes were 100% fuel loaded and the circles were made at the deck. The tests started with Yak-9 being on the 6 of Fw-190. After 3-4 circles Fw-190 got the 6 of Yak-9 and could stay there as long as he wished.

Jigster,

I think your estamation of the F4U-1D horsepower is a little Low. The R-2800-10W had a max combat horsepower of 2250HP. Plus the P-47D-25 and later weighed almost 2500lbs more than the F4U. Well over a ton.

Also the early versions of the P-47 used a Curtis 12ft toothpick style 4 blade prop. The F4U used a 13ft Hamilton standard wide chord three blade prop.  Republic switched to a blade style already in use by Vought. The only difference being that they used a four blade prop instead of three.

In takeoff comparisons a fully loaded
P-47D-25 at 14,411lbs took 2540Ft to leave the runway where as a fully loaded F4U-1D at 12289lbs left the runway in only 840Ft.
Even the paddle blade prop and increased horsepower can't make up the difference in weight and a wing designed more for long range cruising than short carrier takeoffs and steep climb angles.
