Looks like the P-51 got some love with the latest 1.5 hotfix. There's nothing detailed in the changelog so maybe we could list any changes we spot.

 

Audio changes are the biggest thing I notice right off the bat: the tone when you pull the throttle back to idle is different and the sound of the guns in external view sounds different to me too.

I'd love to see some better fuel. What are the odds? I'm UPDATING now, :D Maybe something sweet coming our way?

Didn't notice any changes but I haven't flown lately either. K4 ground crew yells clear now on startup and I thought I noticed some different noises in tight turns under 400km.

Will the P-51 (and TF-51) eventually get the control surfaces forces simulation like the Bf-109?

If you mean trim tabs, they've always been there because the P51d has rudder, aileron and elevator trims adjustable by the pilot...

 

Unless you were referring to any other aspect ?

I guess he means the stiffening caused by airflow/speed. IIRC there is already some stiffening, but not modeled as in depth as in the 109.

Ah! Ok!, although I believe the P51d controls might feel very light over a wide range of speeds, just like those of the Fw190, so, I'm fine with the way it is now modelled...

 

The K4, that's a different story, from what I read in pilots notes / reports, and I think that together with fine tuning of the blackout effect, they're now close to perfect :)

The P-51D had heavy controls.

 

Loops, Cuban-8s, Immelmanns and even a couple of Cloverleafs followed the aileron rolls. We kept the power at a max-cruise type setting (36 inches/2700 rpm), and while the airplane was indeed a pure joy to toss about the sky, I had to work a bit to make it happen. I quickly realized I'd have to spend more time in the gym to be comfortable flying any combat missions in the Mustang. That stick got heavy at the bottom of a loop! I don't think we got much more than 300 kias at any point, but I wanted to pull with both hands a couple of times. Before you tell me to put away my skirt and man up, let me 'splain. Full aft stick in the F-16 takes 25 pounds of force. Always. At 1G or 9Gs, if you're pulling full aft, it takes 25 pounds. (We'll save the discussion of fighter aircraft fly-by-wire controls for another day). Those same test pilots I mentioned earlier measured the Mustang stick force at 70 pounds for a 4G turn and about 90 for a 5G turn at maximum level-flight speed, about 240 kias for their test. Those are estimates, since their force gauge went to only 60 pounds. They concluded that "the Mustang was a two-handed airplane in which prolonged hard maneuvering was extremely tiring." Still don't believe me? The late Jeff Ethell writes in the October 1997 issue of Flight Journal that, while flying the P-51A, "I could move the stick at high speed without using two hands as I normally would in the D." Makes you admire Bob Hoover's airshow performances even more now, doesn't it? I sure do.

Consistent with another report that floats around on the web:

 

MANEUVERING STABILITY stick forces/g at Vmax

FG-1--5 lbs/g (too light)

P-47--7.5 lbs/g (ideal)

F6F--12.5 lbs/g (barely acceptable)

P-51--over 20 lbs/g (excessive)

I don't think the ground crew is new, I noticed it before and I haven't flown it since this last update.

Well, I had a short discussion with YoYo a year ago... as I thought similarly... but it appears that:

http://forums.eagle.ru/showpost.php?p=1970423&postcount=380

1. Why is the pilot so strong? You can rip your wings in a dive by pulling half of the stick. I though there would be some force representation and control stiffening at high speeds modeled in the game that is a sim?
1. Because in Mustang there is no problem to pull the stick for overcome G-limit AT ANY IAS you can create sufficient lift to create enough G's. It's a fact that force gradient per 1g being very pleasant at low at moderate g's became NEGATIVE for high g maneuvers. It means that after you pull certain g the stick force stops to rise and then begins diminish as you pull. Up to zero. THis effect is especially noticable with aft CG.

2. Do not mix excessive dynamic pressure and Mach effects (compressibility). Compressibility effect is noticable during a steep diving from the high altitude (more than 30000 ft). You can see trim changes, violent buffeting, increased stick travel to create certain g. Excessive dynamic pressure or max IAS causes structural damages, especially control surfaces.

And there seems to be a mix of opinions. I have read that the Mustang is pleasant at all speeds, and that in comparisson the 190 is a very stiff aircaft.

 

The F16 pilot says that it got "stiff" but he also says that he "wanted to use both hands" but it seems that he didn't(?!).

 

http://www.wwiiaircraftperformance.org/fw190/wright-field-fw190d-9.pdf

"Maneuvrability and Aerobatics: The outstanding maneuvrability trait of this plane is its rate of roll. In this respect it compares well with P51D and P47 (...). The radius of turn however is poor and elevator forces in tight turns are xcessive. Constant stabilizer adjustments is required in turns and if pulled in too abruptly a fast stall with little warning will occur."

Solty,

 

What you quote from yo-yo does not contradict what these modern pilots describe: 90lbs of force for a 5g turn. It is interesting if it actually decreases past that point, and a non-linear force/g curve cannot be desirable in a fighter.

I just went a quick round with a Dora Offline. The P51 is such a great fighter to fly. It really is the "Cadillac of the Sky".

 

I love how honest the Mustang acts. It is just fun to fly.

Its a dream of mine that one day we will get FFB sticks with extreme strengths.Just look at the new high torsion racing wheels and how they make the racing sims so much more realistic.Watch the end wehere he drives with the wheel.

And did you notice the new detonation effects if you lower the throttle way too much inflight ?

 

I did, nice! But I still like Diveplane's mod better...

It doesn't mater anyway, that test has no place in a discussion on WW2 planes. Those are privately own refurbished aircraft, some of which are missing vital components (P-47 lacking a turbo charger for example.) The owner of the P-51 also put limitations on the pilots flying the aircraft to prevent damage to the plane as another example of it's flaws.

 

It really does hold no authority in this discussion at all. Fact that you can find these flaws negates the entire test.

Hmm, wasn't aware of that mod....

 

But, I also don't know if they're only sound effects, or is actual results from detonation occur in the engine ?

 

It's not detonation as we understand in engineering terms - i.e cylinder related and very bad for the engine. It's actually exhaust popping.

 

Unburnt fuel/air mix being allowed to escape the cylinders and hits the very hot exhaust manifold and combusts with a popping sound. This is often heard in Merlin engined aircraft as they cut power immediately prior to touchdown.
