View Full Version : P-51 falling apart too soon?

Just a quick question to our P-51 lovers. What was the break-up...or should i say...critical speed for P-51 that we have in the game ... in real life?

Take a note, this is not a whine, just a question. It appears that Pony falls apart somewhere from 860-880 km/h as indicated by instruments. So, what was the real deal?

Kozhedub: In combat potential, the Yak-3, La-7 and La-9 fighters were indisputably superior to the Bf-109s and Fw-190s. But, as they say, no matter how good the violin may be, much depends on the violinist. I always felt respect for an enemy pilot whose plane I failed to down.

Breaking up in the 860+ range is not bad at all. In fact, thats probably the best of any prop plane in the game, with only the FW-190 coming close. Most late war planes break up at 750IAS or less.

At higher altitudes 850km/h IAS would translate to over 1100 km/h TAS (the fastest I got was almost 1200km/h TAS), which is nearing the sound barrier.

I`v taken K4 almost to almost 900... by the way, i lost all control surfaces chasing K4 on the dive...twice LOL (First time i didn`t believe what just happened, second time was the last one i did it http://ubbxforums.ubi.com/infopop/emoticons/icon_biggrin.gif)

A bit OT but since the 109 was mentioned: Ky√¬∂sti Karhila answers a question about overspeed in the 109 (i assume he talks about the G6): "- What about the phenomenon called "buffeting" or vibration, was there any?
- No, I did not encounter it even in the 850kmh speed."

Try that in a 109 in FB....smooth ride? That aint it! http://ubbxforums.ubi.com/infopop/emoticons/icon_wink.gif

I think the p-51 might be breaking up a bit early, but I also believe it's close to correct.
Racing p-51s at Reno se over 800kph/500mph straightaways in a level attitude and the record for one lap is over 780kph/490mph.

Although these planes are highly modified, they retain stock wing airfoil shape and structure. The weight is also near stock at 10,000 lbs+.
The reason for the weight is they carry a sort of total loss cooling system called "spray bar cooling" and as a result a lot of water which is sprayed into the radiator sir stream.

Also carried is a NoX system and water methanol. they are not light weights! 3,500hp makes up for it.

My point is that they are running near the airframe limits, and this sim is close. My only ***** is Oleg saw fit to make the P-51 a bit slow at all altitudes, especially on the deck.
By the way, those racing P-51s are running at 500+mph at under 5,000', that's on the deck at Reno.

P-51 is probably one of the most accurate planes in the game when it comes to elements like this one. Doesn't seem like it needs any changing.

I also agree that its very close to correct.. though i think it also depends on the air you are actually flying in... i'v had 190's hold up at 860+ and fall apart around 700, depends on where i am.

I am pretty sure that is accurate, depending on what your altitude is and such. I have personally reached 920 Kph before becoming a lawn dart. http://ubbxforums.ubi.com/infopop/emoticons/icon_smile.gif Now the Jug on the other hand still reaches around 1000 Kph before becoming a projectile.

its accurate but the yak and la should breakup sooner, also the 262 is doing 1020 with razor sharp elevator effectiveness, damn things probally more effective then a f16s flyby wire elevator at high speed.

Dont worry, the 4,000,000 candle power flash stutters make up for it. You cant anything at tht speed anyway... http://ubbxforums.ubi.com/infopop/emoticons/icon_wink.gif

"860-880 km/h as indicated by instruments"

You refering to in cockpit, that would be Mph in this case, and that's pretty darn fast.

http://ubbxforums.ubi.com/infopop/emoticons/icon_eek.gif just noticed it's Vne got lowered. It was well over 1000kph IAS in the RC patch. But still it's got an RBJ rudder that allows bat turns at high speeds without trim-on-a-slider http://ubbxforums.ubi.com/infopop/emoticons/icon_biggrin.gif (although it can even improve the turn rate). But before you bash me http://ubbxforums.ubi.com/infopop/emoticons/icon_biggrin.gif: The 190D or 262 aren't better in these manners. Yet they all should have a great high speed handling, but in FB it seems to be very simple - there's no compression at all. Seems like the stick pressure is just a linear curve in FM, instead of a complex graph which automatically results in such incredible elevators at extremely high speeds if the high speed handling is good. P-47 is also one of these, and maybe the P-39 will become one, too http://ubbxforums.ubi.com/infopop/emoticons/icon_biggrin.gif (it's lacking high speed elevator responsiveness badly)

Dang my bad... shouldn`t have said instruments...speedbar http://ubbxforums.ubi.com/infopop/emoticons/icon_biggrin.gif which is km/h

AS FOR THE p-51 im more concerned about the BLACK OUT issue. there was no way in hell you should not black out so easy.
