Title: Request for p51c
Post by: Citabria on August 03, 2003, 03:54:13 PM
p51c was the faster and lighter than the p51d by a few miles an hour and would offer me and other players an interesting compromise between firepower and visibilty vs speed and less weight with these two aircraft.


the p51c unlike the b was fast at low altitude as it had the same engine as the d but less drag without the bubble canopy and would see much more use in the arena than the b as it could be used in formation with the d and not lag behind below 25k where the fighting happens. I'm sure the mustang squads would find it a welcome addition to their stable.

superfly natedog pyro hitech...
with ah2 coming out would it be cost and time effective to take the 3d model of the b and the flight model of the b and add the engine model of the d? and have a unique 3rd version of the p51 in ah that will get used often due to its superior performance at the cost of armament and visibility?

a nice shiny silver razorback mustang would be quite nice :)

P-51C and P-51B are the same.

The difference was the P-51C was built at North American's plant in Dallas Texas.

Its ez to think they were different sub models however, and why they bothered with a "C" designation is beyond me, maybe it had to do with accounting procedures.

p51c had same engine supercharger gearing as p51 d

p51c was faster climbed better flew further than p51d but had less visibility and guns than the d.

seems like it would be an interesting addition for mustang dweebs. i bet they would actually use it too.

P-51C shoould be easy to develop. Just copy the P-51B dimentions, change or alter the flight characteristics for 51C, and add 4 hizzuka (hispano) cannons.

from the stats/website cit linked to, the p-51c is hardly worth the effort to model as it's almost comparable to the p-51d... i mean 1-2mph difference at listed alts, and less firepower/visibility? :rolleyes:

i think the "hizzuka" load for 51C would not be like the "Chog", i think it would be somewhere around 400 to 360 rds

The P-51K was a 'D' built in Dallas.;)

The first P-51B flew on May 5, 1943, and the first P-51C flew on August 5 of that year. Inglewood built 1988 P-51Bs and Dallas built 1750 P-51Cs.

With the introduction of the P-51C-5-NT onto the Dallas production line and the P-51B-15-NA in the Inglewood production line, the Packard V-1560-7 engine was adopted as standard. It offered 1450 hp for take off and a war emergency rating of 1695 hp at 10,300 feet. Maximum speed at 20,000 feet was reduced from 440 to 435 mph, but increased from 430 to 439 mph at 25,000 feet. 398 P-51B-10-NAs, 390 P-51B-15-NAs, and 1350 P-51C-10-NTs were built, all powered by the V-1650-7 engine.

All preceeding dash numbers of the B/C used V-1650-3 engines.

P-51C didn't HAVE Hizookas.  One of the little podunk British varients had 4, I think it was the Mustang IA.

well whatever it is i want a late model p51b or p51c with the same low altitude top speed as the p51d.

thanks :)

Weren't the H's and K's the same aircraft, not the D's and K's? :confused:

No Kevin, Milo has it right

The "H" model was the late war, lightweight version of the Mustang that was never put into production.  Roughly equivalent to the P-47M/N.

There was 555 P-51Hs completed before V-J Day,  out of 2000 P-51Hs ordered, made up of 555 NA-126s and 1445 NA-129s with minor differences.

The Dallas built a/c was to be the P-51M.

Ok, thanks for clearing that up :)

The "H" was mass produced.  As were the P-47N's (N is just a modified "M" imo with the clipped "wet" wings).   But post war it was not favoured by the crews and pilots (and the Air Force/ANG) that used them. My readins on the model indicate the more rugged D model was preffered. The D model they had more of and in particular more spares for with which to maintain and keep them running longer too.

No merlin powered Mustang (B, C, D, K, H) served with 20mm cannon.

The K was a D with a slightly different prop (built in Dallas), and was just short of the Ds performance. Why the different prop, I have not been able to find out.

The major reason for the prop change was due to availabilty. Hamilton Standard was unable to produce propellers in sufficient volume for the high level of demand. additionally, the War Production Board urged aircraft manufacturers to use different sources to assist with boosting growth of the smaller companies as well as for common-sense strategic purposes. A fire at the H-S plant could shut down the only source for weeks. Multiple sources meant less disruption due that type of event, or even something as simple as a strike by unhappy employees. So, several manufacturers went with the Aero Products props, including Grumman for the F8F-1 Bearcat. Still others were using the Curtiss Electric props (generally disliked for several reasons) Unlike the H-S prop, the Aero Products prop lacked the airfoil shaped shank cuffs, which reduced total thrust enough to result in about a 4 mph loss at max speed for a perfectly tuned, perfectly clean airframe. Since no such thing existed in typical combat service, actual performance differences weren't really discernable to the pilots.

P-51Ks had a slightly different shaped canopy bubble as well, again due to a different manufacturer using a slightly different shaped mold.

My regards,

Widewing

How would an Allison engined Mustang fare in the MA?  Was the Allison better at low altitudes than the typical Merlin 'stang...better acceleration and/or speed?  

And I know how those four cannons would perform.

From what I've heard the merlin was slightly better than the allison at lower alt, but was alot better than the allison at med-high alt.
