Nope. Higher angle of incidence of the bubble canopy resulted in lower drag on the D model. the D is just as fast if not slightly faster.

True Air Speed. Tacview Agrees. Shows the same speed in MPH converted from knots since that is what I have my Tacview set to.

its TAS.......

His TAS was already 348mph. Unless you for some reason think DCS doesnt calculate TAS correctly.

Yes, that is also true. The ones on the P-51B in those tests are the old racks.

Since we cant agree, how about this: You are all focusing on the B models for some reason. The D model WITH racks did 442mph at 26,000ft and 375mph at SL. WITH WING RACKS. With an additional 200bhp, it would go faster obviously, making it just as fast if not slightly faster than the 190D and K4 at SL. ALSO note, the P-51B in tests was tested with RACKS, so all of that is legit as well (and I recall it did 380mph at SL.)

Honestly I dont think this matters. The wing racks weren't permanent fixtures. A player should be able to remove them, especially since the combat in game isnt typically at 35,000ft after flying for 6 hours.........and the P-51D racks have negligible speed loss. If the P-51 had 150grade in game all 3 of our fighters would be nearly tit-for-tat on every performance figure. Speed on all fighters would be in the 440mph area and climb on all fighters would be about 4400fpm. If we had a different model of 109 with the option of gondola guns, it would be equally silly to make it impossible to remove them. The ETC racks also cause drag.....0-2 mph depending on weight.

No. You are wrong here regarding the racks. For one, P-51s dont come with racks simply because they have 150 grade fuel. Second, the racks on the D model and B/C are different. The ones on the D model took at most 4mph off top speed, the ones on the B took off more. Did you even realize the racks were different? Thirdly, the the 12mph figure stated in the tests you apparently scantily read is an estimate, not flight tested speed losses. The reason for this is that the amount of speed lost due to the racks is heavily dependent on drag due to weight. The speed loss quoted is from the assumption of a very heavy pony, not one at combat weight. You will notice that on both the B and D models there are tests with and without wing racks with nearly the same speeds given. Lastly, the P-51D WITH racks topped out at 375mph at SL at 67inches. A 75inch pony would be as fast, if not slightly faster than a Dora or K4 on the deck and at every other altitude. And rarity does matter, if just so happens your content with this setup. If the only German plane done was the 262, or the only American one the F4U-4 simply due to document availability, I doubt anyone here would be happy.

I have the new one. It still climbs at 30m/s

It isnt any faster. Ive matched the specs before, and it continues to be slow. Also the K4 is still climbing at around 30m/s

Excellent point. Aviation enthusiasts spend alot of time debating turn performance and roll rates etc. Anecdotal evidence wont tell you the finer details of two aircrafts performance, but when both sides think their ship is the best, its safe to assume that within the literally infinite conditions fighter combat began and ended, most aircraft probably fell into the "good enough" category with regards to knife-fighting characteristics in particular.

I dont think a P-47M is necessary, but it should would be nice to get a P-47D-30 with 150 grade fuel belching out 65-70inces of boost.....

Those all sound like reasonable improvements to the game

Because it would be a logically unnecessary statement. It stand to reason that any flap system moves the flaps to a desired position and doesn't movie unless something makes it (like in a full blow up system). IE: I move lever, thing happens, and machine doesnt decide for me what flap setting I want(in non-overspeed). If we assume the flaps DO move during over speed, why would any pilot expect the flaps to move in any other condition? If I put flaps down in a plane, withing the normal speeds, I wouldnt expect them to go down on their own. Nor would I expect them to deploy if I didn't intend it.

Think about that for a second. For what reason other than over speed would the flaps move without the pilots command? It would seem quite silly if the flaps simply moved on their own without pilot command. Yet, they are clearly stating that the flaps will NOT move unless the pilot moves them. Seem like a odd thing to be so clear on. As was previously pointed out as well, I cant imagine why youd need to put a placard in the cockpit and manual warning the pilot of over speed if the system was automatic. It says dont deploy flaps at those speed, implying that you can....Why not state: Here are the speeds you cannot do, but the system will take care of it for you so your good.

NA 5914 "When you move the flap control to a certain setting, the flaps will move to that position and remain there until another is selected"

The F6F has a full blow up system, and the F4U a partial one. The P-38, P-40 and P-51 do not. With regard to how that matters he states: The F6F flap actuator rods are attached to heavy springs that "sleeve" if you will through the center of the spring. The springs attach to the flaps. So in the F6F you just put the flap switch down. As you slow down, the flaps start coming out at 140 knots, and are full down at 93 knots. Speed up and the flaps go up.

So.....every aspect of a plane is perfectly engineered then? Not possible to make something that doesn't fit with your view of necessary? Neither of us designed the plane, so ask them not me....

:megalol::megalol:

I dont think it is the DM alone. I just dove the plane to quintouple check and after deploying to max at 6000m I dove past limits and it flaps go up like clockwork as you pass the do not exceed speeds. It certainly is DM related on the 109, as I can put those flaps out at 500mph without damage.

He states: The slip stream or air load won't keep the flaps from going out. Though if you are at 500 and go flaps 50 or full, they may just we'll break, bend, break the actuating Rod etc before they get all the way out.

He states: No. I've never over sped the flaps in the 51. I don't want to fix them. but I've flown, built, serviced, overhauled the Hyd actuators to know.

The pilot has given permission to quote his name. Chris Fahey. He also gave me this to say: "They will go down over limit, with 1200 lbs of pressure or so, and to much over limits and you will damage the flaps, or structure. There is no blow up in the Mustang, or limit other than position of the flap handle and the pilots brain." Additionally: He states these pilot can confirm this as well: John Muszala, Scooter Yoak, Rich Palmer will all confirm this.

He was not angry. And Im not certain why that needed commented on.

He was not.
