P_51D EVA files

gosd look at every other xdp at the top line.it should read <General Allegience="0"
There is no / untill the end of a segment which ends like this /> i just checked both uploaded xdp's and they are correct. your problem is somewhere else.

anyone else haveing a loadup problem ?
 
...The flight model debate will likely go on for years yet...

Quod erat demonstrandum

...when the program runs the player aircraft.it "grabs" it 1/4 the distance back from the x gmax line to the back end of the tail....

I don't quite understand you Slip? Having looked at a few of the stock models, the gmax or modeller's centre is at the point of the nose - Tempest and Spit models are prime examples. The aircraft.cfg reflects this.

The flight simulator's centre - the point at which the flight model balances - is generally 1/4 of the mean air chord (average wing width) back from the leading edge of the wing.

If the flight model centre was 1/4 of the distance from wing leading edge to tail back from the leading edge, the model's pitching behaviour would look very strange in the sim, but in fact the models pitch around a point a little back from the leading edge.

Please elaborate?

@HH - now you're just being a naughty hobbit again! :icon_lol:

Yea Hairy just picking on the Brits again..
If ya see me hanging from a tree by my feets again who you mind cutting me down please..
They get very upset with the truth sometimes it seems..:icon_lol: :icon_lol: :icon_lol:

But to be honest I am truly grateful that we Americans did come to the aid of the Brits, and Japan did make a BIG Mistake attacking on Dec. 7th..

And Herr Hitler by declaring war on America saved the president from trying to sell another war in Europe to Americans

It must be admitted that America didn't want any more part of wars in Europe
WW1 left a bad taste in the mouth of America..
America had to come to England- France aid then too..

But Thank God we did come to the aid of England in WW2..
I would hate to have had it any other way..
Would hate to think of the "SS" ruling England..

BRAVO.. to the Greatest Generation who Saved the world..
And to all who stood against the darkness during this time..
:salute: :salute: :salute:
 
said i was waiting G.obviously your not reading the write ups or posts.so here it is.the degraded flight files you did for nigels 109's are unlikeable nicely puting it.

Unlikeable? Perhaps, but very close to the real life specifications. The late model Bf 109s were some of the most uncomfortable aircraft out there to fly and a realistic flight model should reflect that.

can't teach you manners.

If by teaching me manners you mean trying to make me shut up about my opinions backed up with real life facts, true, you can't.

not the stockers.microsoft made this sim as an online game play.where all the planes were made just about the same,to level the playing field.your capable of opening and compareing all the original cfs3 airfiles.look for your self.

So that's why the stock Spitfires outfly everything imaginable, the stock Fw 190s can barely make a turn without coming down like bricks and the stock P-51s stall randomly at will? I'm inclined to say it's just bad flight model design which wouldn't be anything new to Microsoft.

thankfully the third party builders found that out and start theirs on the leading edge. makeing for a generally better flieing plane.you believe that the stock air files are correct.

I certainly do not believe the stock air files are correct, I've flown only AvHistory from 2006 when I first discovered them.

do the real ww2 fighter planes make a left or right turn and FLIP back over the other direction and go into completly unrecoverable spins? NO.

With the exception of P-51B/C/D/K series with fuselage fuel tanks, Fw 190s, I-16s, Fiat G.50s, and that's only to mention a few.

the real aircraft can do inside vertical loops.the stockers can't. flaps on real planes make lift and drag. stockers don't.real aircraft slow down when you back the throttle to zero and start to loose altitude.not the stockers they will keep going like a glider.

As said, bad flight model design. Very bad.

every real aircraft built. has its owen power curve according to the equipment and aircraft design. cfs3 doesn't. we're stuck with a unidirectional power curve.and a manual wep.cfs3 can't produce reverse thrust. the critical altitude is set so low on all cfs3 aircraft. they won't handle and are power restricted.both to less than 20.000 feet.

CFS3 allows full control of engine efficiency at whichever RPM you wish, allows setting the critical altitude to wherever you want it and setting the WEP critical altitude independently from that, and yes it can produce reverse thrust. Try setting propeller blade angle limits to negative figures and you'll see.

Some of the stock aircraft have their critical altitudes below 20.000 feet, agreed. Because they should - mechanical superchargers have their limits and very few models were optimized for extreme altitudes. Then again the turbocharged P-47s and the P-51B give full power up to 30.000 feet.

The real life V-1650-7 in the P-51D gave full 60.5 in/hg boost up to 26.000 feet, producing 1260 bhp at that altitude. After that the power fell of quite rapidly, at 30.000 feet it only had 51.6 in/hg (1075 bhp) left and at 40.000 feet the figure was down to 32.8 in/hg and 630 bhp.

real aircraft can't flat flight corkscrew at the rates the stockers do.theres more but the point is made that cfs3 aircraft flight files ARE NOT ACCURATE.

So for the third time we see (and agree) that the stockers are hopeless. They really are. The actual flight model files themselves are surprisingly accurate but it takes something else than the stock data to get a well flying model.

thats why alot of people blew off and bad mouthed cfs3.they wanted planes set up more like these.i was talked into putting them up after holding them for 5 years.now for all intents and purposes cfs3 is pretty much DEAD.most of the builders have moved on for many reasons. some because of fourm response like this.

Those people either didn't know where to look, didn't appreciate realism or just got fed up with a marginal sim. I can fully well understand why few people want to build things for a sim with dozens of users when the alternative is building for a sim with thousands of them.

NOW THE NASTY remmember a thread i started called "follow the leader" i do ! i was looking for a test pilot.i posted pics of myself flying aircraft inverted through hangers.and wanted others to do the same.a guy dared someone to fly inverted under the tower bridge with a B-29. ring a bell yet ? you posted a picture of a B-29 flying under the road platform inverted.remmember now ? i do. i downloaded the picture and opened it in photoshop.sure enought it was faked. and it was the second time you posted the same B-29 pic.you let it ride as real. i did it for real and ended the thread without finding a test pilot.again i was gentleman enough not to call you on it,on public fourm.and make you look like a cheater. oh well.on top of the negative posts. thats why your word,opinion and work mean nothing to me. :hatchet::rocket: hey look there are, different imodicons.

Ah, finally my favourite part of the post. No need for the axe and bazooka though. I remember the thread very well and it was a real challenge to get the B-29 through the gap without the vertical tail hitting the water. I'm suspecting your Photoshop is broken because it was real so of course I let it ride. See pictures [1] [2] [3]. You should have called me up on it right away, gentleman or not, if you suspected something - I'd have posted these back then!

The funny thing is that all this began from me saying that a critical altitude of 41.000 feet is unrealistic for a Packard Merlin, as is unlimited WEP. I won't change my opinion of those because both of them are facts. I can agree with you in saying that this version is more fun than the stock P-51D (which is horrible) but realistic it is not.
 
Owen, I'm sorry but... :wiggle:

The Brits didn't have anything with long enough range to cause them a problem, so it was up to the P-51 to take the airwar to the Germans..
Thus the greatest fighter the allies had..
The one that could match the Germans in their airspace and get home..

Hey we all should be grateful that the USAAF had the Birds needed to defeat the Luftwaffe..
The Mustang was developped from a RAF demand, they requested specifications that were far away from USAAF ones. Originally, USAAF didn't want to hear about this aircraft: P47 and P38 only.
The fact that the aircraft had a so long range is a hasard, they created an aerodynamic effect they will not discover before the end of the war.

And, without the Merlin engine, this great fighter would never have been able to play the role he did.



As Churchill said when informed of the attack on Pearl, the first words out of His Mouth was "WE ARE SAVED".
Winning a war is 90% a matter of logistics.
Once USA was in the war, it opened nearly unlimited ressources for the allies and none of the axis nations were able to bombed them, the US industry was unstoppable. This is why having USA into the war was so decisive.


My opinion regarding WWII is that the real decisives battles were fought in North Africa in 1941. Commonwealth didn't lost Egypt and kept a foot in Mediterranean area, that's the key.
Then, USA entered the war and landings one year later in november 1942 were performed with new escort carriers that were started to be produced at many units per month, something that England was not able to do. Just an exemple.
From this point, and with the giant Russian industry that was producing more and more war machines, it was the end.
Then, it was a matter of strategy in order to find the best way to end this horror as quickly as possible.

I'm not sure that Germany wanted or could attempt an invasion of England in the summer on 1940.
 
...I am always intrigued by the campaigns in North Africa... Love those desert Hurricanes and P-40's:jump:

LOL..LOL..LOL..
I shall admit I did this only to get something happening here..
Was getting Boring in the forum..LOL..

I realize the p-51 is NOT a Super bird..
And it was a British order which brought life into the P-51..

It has had the effect I had hoped for..
Got it all stirred up here as we say in Kentucky..
And I do enjoy poking the Brits with my pointed Hobbit stick..:applause:

Now would some one be so kind as to shoot the rope they ( Brits) have hung me
by my feets again with..

For some reason they seem to like hanging me upside down whenever I do this..
Thanks all it was Great fun poking the Brits..:icon_lol:

Now shoot me down please..:tgun2: From this tree..:icon_lol:
