Very serious problem with the flight model for the Delta Winglet paint. This is my third flight and the AC flies nose down. The climb out is painful if possible at all. Descent when I have got it up to altitude was like flying a missle down. I have check everything I can find in the setup menus, including weight and balance etc. Can't see anything, the house paint flew fine. Whats up with this? Help please. BTW I have uninstalled and reinstalled the paint several times including making sure the file was not read only. Anyway, just frustrated. Joe

Joe,Confirm you have Use Indicated Airspeed checked in FSX?Weather app?

Yes, IAS is checked.I can not get it over about 180 knots on departure . . the AC is clean . ..

Are you using any external weather app? Do you get this even with the Clear Skies theme set?

woops, forgot using ASE.I have checked for icing, pitots and actually, I am flying in some fairly stable weather. It just will not climb now. It did this before,but all of a sudden it just pulled out of it and flew correctly. It is like i am overweight, but I am not, have check everything. . . .it is like the airfile is a mess, burning fuel like no tomorrow . . .as well . .

Can you try with the Clear Skies theme and ASE not running please? Just need to make sure this isn't some bogus temp or pressure in the sim coming from ASE.

Ok, I finally got above 20,000 ft and it suddenly started to fly correctly. Now I know that may indicate settings and weather, but I have tuned this setup to the tee and have flown it for years and have no problems like this with any other AC. In fact, the house PMDG flew just fine. Anyway, unfortunately I dumped my vatsim flight befor it recovered and now off line . . . thanks, I really love this AC. She is a beauty, just want it to fly . . . LOLok, but watching the weather, temps, winds etc. already. Now it is flying fine, did not do anything but check my calibrations in FSUIPC. I will keep my eye on it and run clear as well, into Seattle tonight . ..

Joe, Please do another flight with no weather (Clear skies) and report back if you see the same issue. I had the same during beta but we could not pinpoint the problem. ALso if you could add any and all addons you have installed for FSX would be great. Thanks,

Ryan, I will keep at it and give you feedback. I am a homecockpit builder and have several external USB modules like PFC 737NG throttle, go flight etc, that are not working well yet either, but that is to be expected at first and so I am saying there are a lot of variables on my system. I will give the clear weather a go. Just curious that it pulled intself together but the pitch is questionable as well on departure and approach. Anyway, thanks much.

So we can't fly this bird in weather??

Addons- ASE, Active Camera, TrackIR, FS Real Time, some mesh programs, GEXNA, REX clouds, Utah Complete, but that is about it for software addons, cleaned it up in anticipation of the NGX. Thanks Joe

So we can't fly this bird in weather??

Nobody is saying that, they're just trying to rule things out to see where they issue might be.

The house 800 works fine, this is an issue that is showing up with the delta livery. Not sure that it is weather related at all, a lot of variables here. Just trying to find the needle . .

Hmmm, never had much problem with ASE before. So what do you use, REX weather???

I have had serious issues with the NGX in weather too, nose down climb, not able to climb very high. etc. I am reinstalling FSX as recommended at the moment and my addon list is in my post.
