After hearing so many good comments on the PMDG 737NG and reading excellent reviews I decided to buy it (the PMDG 737NG 677/700, I still don't have the 800/900s). I have used it for just a few hours this past weekend and I agree with the critics this has to be the best FSim add-on ever!The only problems I have experienced is a couple of very anoying crashes to the desktop in both cases while clicking on FMC buttons, the whole screen would go black but the FMC would stay on for about 1 or 2 minutes while FS 9.1 is crashing to the desktop. I am running the PMDG 737NG 600/700 on a very stable FS 9.1 install on Windows XP Pro SP2 and the fully licensed FSUIPC 3.4.Overall I am very satiscfied with my PMDG product, the fligth dynamics are great, the sounds are amazing, the panels and gauges are readable and run very smooth, the visual model and liveries are first class, event my PFS are great, the whole experience has been excellent.Only 2 negative comments: (1) my two crashes to the desktop, I hate when that happens, and (2) the manuals could be better, specially the sample flight tutorials, which should include screenshots to help newbies pinpoint where things are.Ohh, another thing, following Fred Clausen's flight tutorial, my engines won't start, I mean they try to start many times but give up. It takes me like 10 minutes to get those engines started -- my ignorance about the product more than likely, but if anybody knows what I'm doing wrong I would really apreciate the assistance.Next on my list is the 800/900, maybe next week!Ecellent job guys,Kerke

Glad that you are happy overall. Don't have a clue about your crashing issue but would like to comment on your second negative. As you might already know, learning this aircraft and it's systems is like learning how to fly the real thing. The manuals cover all aspects like the real manuals , but just like the rl manuals, they do not tell you how to deal with every situation or how-when-why you use a certain mode etc. I don't believe this is a real problem because there is more information contained within this forum (use the search feature) than any tutorial. The fact of the matter is this, there is no ONE WAY to fly this aircraft. You can find Mr. Brad Marsh's GEEZER GUIDE for the NG here http://homepage.powerup.com.au/~speedy/737start.html A great help.

Thank you both for your replies. As it turned out, I was missing a couple of steps in the engene startup sequence ;-)My 737NG starts just fine now. As far as the CTD is concerned, I did a little flight last night (KATL-KMIA) with the "American 737-700 2D Conckpit only" and everything went OK. In fact, this flight went better that OK, it went incredibly smooth!Thanks again,Kerke
