Yo-Yo - 2 / JCOMM - 0

Ok, he plays at home, but anyway, he won twice in a row...

 

What am I talking about ?

 

1) That thread down ( or up ) in the forum regarding the pitching moments due to flap deflection, where I finally got yet another confirmation, from a RL p51 driver, that indeed what we see in DCS's P51d is CORRECT!

 

Link to that thread: http://forums.eagle.ru/showthread.php?t=149076 ( skip to the end where I post the answer from yet another Mustang pilot... )

 

2) This was a game that took place long ago, and it had to do with the rolling moment I was observing in the P51d, specially with the flaps deployed during takeoff, under stron x-wind situations.

 

I argued about thinking the rolling moment although I could understand it was true, could overcome other factors, but the chapter on Directional Stability from FLIGHTLAB.NET, if you read the last two paragraphs on page 4.7, although about sideslips, does a nice job justifying exactly the effect when during the takeoff run the aircraft and the pilot trying to maintain the rw heading, are actually in a sideslip condition, and the deflected propwash from the prop, initially ( as the takeoff run starts ) at it's max speed and energy, can well account for the effect we can sometimes feel in the P51d, and also in the Fw190.

 

So, two in a row means I owe another beer to Yo-Yo :thumbup:

It does amaze me how close DCS gets it.

[BSS_Sniper]

I'm not sure why it was ever questioned?

And it seems to be all based on Yo-Yo's genius.

 

And again, in my mind the question arises if 3rd party developers have the same level of skillsets needed to achieve what Yo-Yo is achieving...?

 

Makes me wonder if ED is helping 3rd party devs out by "lending" them Yo-Yo's talent to get their EFMs right. :)

 

Thoughts?

[*Rage*]

I severely doubt any of the 3rd party teams can come close to Yo-Yo's calibre.

Agreed! Yet the question still stands - wouldn't it be in ED's best interest to make sure the 3rd party developers get their EFMs "right" by letting Yo-Yo do them?

 

I mean, honestly, it's one thing to knock out planes for FSX/P3D with their "relaxed" flight modeling on those platforms, but it's a whole different ballpark making a DCS module with EFM, with ED setting the standard -- and our expectations -- extremely high.

Because, as you probably know, and I at least do know, after 35 yrs flying for real, some aircraft do indeed immediately pitch down, or up, as a result of flap deployment ...

 

The P51d modelled in another sim, by a talented 3pd, immediately pitches down as flaps are deployed, while dcs's p51d pitches up first... and while this could be easily understandable by me, I would really like to be sure that is indeed the right behaviour.

Yo-Yo is a finite resource! You only need to see how much trouble most of the 3rd party devs are having with their flight models to figure that out.

Exactly!

 

PS: Sorry jcomm, didn't mean to hijack your thread :)

Yo-Yo is a professional who creates FMs for a living, its surprising he is right about stuff so often huh... ;)

Of course SiTH.

 

But, also a word of recognition to Crumpp who, at the thread and through PMs, kept trying to open my eyes to some interesting facts :-)

 

My biggest problem is, the more I like something, the more I demand from it, and flight simulation, presently translated into 4 flight simulators, is no exception...

 

I was brought to DCS by a great friend who told me, soon after the p51d was released, he had something to show me that would fulfil my requirements and wash my disgusts regarding the really poor modelling of prop aircraft in most flight simulators. He was right, and the P51d was the first module I bought.

 

Others followed, but I really do not like or want to learn the complexity of modern air war, so, I gave away most of my keys, and kept only the p51d, the K4, the D9, UH-1H, Mi-8, and an exception - the F86!

 

But as much as I would prefer not to play war games, truth is, if I have to play them, then I prefer the older / classic style of ww1 and ww2...

 

Really looking forward for more DCS ww2 modules, and a Map - a Map would really make it all even more tempting :-)

Thank You, Jcomm!

 

Shoot me a PM and let me know how the glider competition went!

Sounds like my story! I had actually snapped my old IL-2 disks in half, years ago; that's how disgruntled I was with the lack of fidelity in that and other "realistic sims" of the day.

 

I often refer to DCS affectionately as "my miracle sim," because, ten years ago, I would describe a hypothetical simulator to my simming buddies, then conclude "but there'll never be one like that, 'coz there's no market for it." But here it is. Or pretty close, anyway. Nothing's perfect, but DCS meets my practical standards. It's the only flight sim/game that ever has.

 

Now we just need a Yo-Yo-made P-38 ...
