Well, actually SW, I have read this entire thread today. And I was so bothered by it that I decided to check other posts in this forum.

Stuff that got me concerned so far are this rollrate issue, the d9 compression and 190a5 speed at sea level and 190a5 climb speed. I'm not gonna post any opinion on these things now, since I have not been able to test them myself yet. And the last thing this forum needs is someone diving into a discussion armed with nothng but his opinions and expectations.

But I will when I get home from work later tonight.

If you read the entire thread, in order, you would of connected my posts as replies to others in this thread.

Did you check this thread regarding the 190A5 top speed:

It sure doesn't look like it needs to be changed according to Dtango's calculations.

What's striking is that now Dtango's calculations based on guesses outrun the factory speed chart presented..

I can't see the logic there.. :)

neutered is a bit harsh ... for a not so great difference.

If you want to see a neutered roll rate just get a pre 1.04 Typhoon and compare to the actual .

Yes-

 Exhaust thrust makes an impact. Looking at the physics CD0 ~ .027-.028 seems to be in line while the CD0~ .025 is not. The math here says that if the SL topspeed of the A-5 is 351mph, then the expected 21k topspeed should be 431mph.

If the calculation prove that the SL speed is in fact wrong in the game, then it also proves the A-5 charts wrong at 21K.

How does Dtango's exhaust thrust impact the original chart presented? One player presents a calculation estimate of flight performance that overruns the original chart?

Pfft.. :rolleyes:

But does the calculation really show that? And see my question to Dtango in the other thread. And he is saying he is using approximations, surely that must have some effect on the calculations? I really know too little about this stuff, but I find it very hard to believe that the factory charts are so wrong.

I never said the factory charts are wrong... but the thing is, if the A5 in game matches the charts at 21K... but is off by 16MPH at SL... then there is something that neither the calculations or the chart are going to prove/disprove the A-5's in game performance.

Atmospheric conditions, what time of year, etc. Cold air expands much more than warm air when it is super heated in an explosion. So if it's the dead of winter, you are going to get higher performance than the middle of summer.

The calculation shows that at SL the chart and Dtango's calcs match up. At 21K, the calcs are showing 431MPH... when it should be closer to 407MPH.

And what is SL in the chart? 0ft ASL I'd assume... as you know, 0ft ASL means you will be scraping water or ground.. so is the chart actual tests or is it too simply calculations?

EDIT: I said AGL, meant ASL.

to discuss Fw190A5's speed you've got the other thread. This is about rollrates :)

thank you :).

P.S.: AH's Fw190A8 performance is almost a copy from a FW-labelled chart

I wondered myself why AH's Fw190A5 doesn't follow a similar labelled chart, and the only answer I can find is than HTC probably didn't had that chart when they modelled the plane so they modelled it after the USAAF report.

Now they got the Focke-Wulf original chart I'm sure the Fw190A5's speed will be looked and corrected by Pyro, sooner or later, as soon as he has some time to do it :).


Now, back to the roll rates ,please :)

We have not changed any performace figures on any plane, including the 190 roll rate for "game play/internet resones".

That's all I wanted to hear.
Thanks for the answer HiTech, (I must admit I was kinda worried a couple of posts ago).

Then we should suppose the initial roll rate was simply wrong, once corrected the warp went away. That, or a deep change in code to optimize that kind of data transmission/representation.

It did? Nah, I think people got over using the LimpWristed shuffle as it would lead to carpal tunnel later on down the road.
