I have purchased a new alienware area 51 alx. Top of the line. 6gigs of ram dual ati 5870 graphics cards( i think that is the name of it somethign like that) ....well here is the problem....Installed flight x many times regular way and under admin...and with vista compbatily everything..... but when I install flight x it works fine. The reverse thrusters open up and stay open. The problem comes into affect when I install abacus airbus fleet that they no longer want to stay open. The reverse thrusters open and then like 2 to 3 seconds later they start going back and forht back and forth ..like they want to shut and open...Also the airbus a340-600 doesnt want to get up to speed to take off... Of course all the good airplanes are add ons cause microsft wouldnt give you the good stuff. I tried installing windows xp64 and still the same problem. This never happend on the old computer that was just plain home. I started to think maybe it was the graphic card so I tried disabling one of them ...didnt work...I tried turning off the aero theme still doesnt work.I have searched the web for this problem but no one seems to have my problem. Dx 10 is turned off. Also this happens in a century of flight.

Install on separate harddrive according to http://www.simforums.com/forums/forum_posts.asp?TID=29041Use FSUIPC to set up controllers.

Abacus Airbus Fleet :( Abacus aircraft are freaking horrible. Take an Airbus, which is one of the most difficult airliners to simulate for FSX, and add in Abacus, makers of the most horrendous virtual cockpits and terrible system modeling and what do you get? :(Sorry, I couldn't resist.For good FSX aircraft, I suggest PMDG, Level D, Flight Sim Labs, Captain Sim, Aerosoft, FeelThere, and Flight1.As for settings up reversers, you can do it with a registered version of FSUIPC, but I set it through FSX. I have "decrease throttle quickly" assigned to the middle axis of my saitek throttle, which when pulled all the way back sends a button command that triggers this assignment. I have it set to repeat with the repeat setting maxed out.
