Title: The 51B
Post by: dirt911 on May 07, 2010, 06:19:33 PM
P-51B i know its a rare plane in AH However i do fly it allot seems to fit the game well in MW and LW.Although i have a question about it which engine is the 51B running in AH?

The B is more popular than you might think in the LW MA.  As of today, it had a k/d ratio of 1.06,  that's not bad.

Hmm seems fair enough but thought the 51B in ah was running Allison.

No P-51B ever had an Allison.  AH has never had a P-51 powered by an Allison.  I assumed your question in the OP was about which specific model of Packard Merlin it was using, and that I do not know.

Most pilots in world war 2 liked the B version of the mustang over the D version, reasons why i don't know. my guess would be because it handled better.  :)

IIRC B runs a Merlin 61, D runs 66. :salute

No, that is a Rolls-Royce number series.

The in AH Spitfire Mk IX has a Merlin 61 and the the Spitfire Mk VIII has a Merlin 66, the P-51s both have American built Packard Merlins, not Rolls-Royce Merlins.  The 60 series is a Rolls-Royce series.  Further, the Merlin 66 is optimized for mid and low altitudes, well below the P-51B or D's best alt.

P51B
Packard Merlin V-1650-3/7
1,380/1,420 hp, two-staged supercharged, 12 cyl. V engine.

P51D

It's not so bad. Who was the USN pilot that responded to other pilots wanting more guns on the wildcats with "If you can't hit with 4, you can't hit with 6"

I've landed 7 kills in a B-pony in a single dogfight (no hotpad, not multiple fights, all one furball), so it's quite capable. I just wish all the ammo ran out at the same time like the FM-2.

What do you mean, "where"?

P-51A is right there.  P-51C is a P-51B built in Dallas instead of Inglewood, CA.

I am not as familiar with the Packard Merlins, but I know that they don't match exactly.  The Merlin 266 is the Packard version of the Rolls-Royce Merlin 66, but the critical altitudes are 1000ft higher for the 266 than the 66.

My point is that his statement that the P-51B uses a Merlin 61 and the P-51D uses Merlin 66 was flat wrong.  Even your initial statement that they were 60 series was wrong.

You can go find it under "P-51D" in the hangar.

P-51A has not been introduced, just as many other aircraft have not, due to other priorities.

P-51B is the same as P-51C, just built in different locations.

That cant be right.



P-51C



Packard Merlin,V-1650-7,1,490 hp,Two stage supercharged






P-51B

Packard Merlin V-1650-3/7,1380 hp.or 1,420hp Two stage supercharged.

All in total they travel almost same speed but.Just would be nice to intro all 51's to AH.
Title: Re: The 51B
Post by: Squire on May 08, 2010, 09:37:40 PM
1420 hp to 1490 hp is .05 of 1 percent difference.

Sometimes engines are listed as different hp even though they are the same engine as in the case of the sources for the V-1650-7 that you listed. The B/C Mustang was the same a/c. One was built in Dallas and one was built in Inglewood, as the previous poster indicated. For all intent and purpose they were the same a/c.
Title: Re: The 51B
Post by: Karnak on May 08, 2010, 09:38:09 PM
You can find either with either engine as I understand it.  The only difference is point of manufacture.
Title: Re: The 51B
Post by: smoe on May 08, 2010, 10:30:44 PM
Gotta remember that engine hp is a loose term. Even auto engine hp in the 60's could vary considerably depending who did the calcs.

It's amazing to me that folks want to come in and argue with things that just aren't that hard to confirm though a little research of their own.   The recent batch of P51B vs P51C threads being a good indicator.

P51B-Inglewood,California.  P51C-Dallas,Texas. 

Heaven help you guys when you get around to the folks who manufactured Corsairs under license, or any of the other birds that were built by different companies.  Give me a TBF!  We only have the TBM!    Where's my FG1-D! We only have the F4U1-D!  I want a Vega built B17!  Ours is Boeing!

It's enough to make ya weep.   :cry

Would be even nicer to get a German heavy bomber, at least 1 Russian bomber,  Any sort of additional Italian air craft, Japanese light bomber, float planes, remodeled aestetics, and so many other things i cant think of right now...

the only significant differenc between the B and the C model was where they were made.  We already went through this on another thread. It would be a waste of development resources to make a C when the B is essentially the same aircraft with the same performance.  If you want to fly a C, up a B and pretend its a C model.
