Sorry for my bad english.At instant replay spoilers (armed at approach) are shown in open position. Do you plan to fix it?And another question - I want to buy the MD-11 will not be any problems with the established NGX?

Known issue, not fixable due to limitations with all the advanced animations the NGX uses. You can use FS Recorder, I believe that works properly with the NGX.No, the NGX and MD11 don't conflict with each other. I own both myself.Also, FYI: http://forum.avsim.net/topic/361815-pmdg-forum-rules-please-read-before-posting/ (rule number 1)

For me in instant replay the thrust reverser animation doesn't work while watching the replay,

Yes, and it, too. In a perfect model is not implemented such a simple thing.But anyway - great!

It's not that simple.FSX's "recorder" doesn't actually record like a video recorder that you're used to. FSX's recorder is more of a "positioner." It only records the position of the plane and a few other parameters, but not specifically what the plane is doing at that time (reverse thrust and so on). Try it on a default model, or even a simple 3rd party model, and you'll see similar results.As is always mentioned, it's not something you can really get around. I can't tell the FSX Replay feature to pay attention to something unless I reprogram the recorder, not the plane.
