PMDGexpress

In my opinion, currently the best PMDG'S product is PMDG MD - 11.I´Have not updated it, because I´Think that the flight will go some way tainted or something. I´Ve heard something about gossip.

Calibrate your aileron, and your throttels, some times it works. Or you can try calibrate PMDG 747 in alt - menu, press alt, and select PMDG, and you can get options. I hope this works.P . S . Nice Landings.

Are you updated PMDG MD - 11 ?.

Yes it can be work, if you have other PMDG products. Remember: your FSX need run lots of memory.

Try change something animation, or visual effects it can be work.

I´think is it validation problem, but the video is called PIRATED PMDG MD - 11. Have many illegal PMDG products, and I´don´t like it.

You only need install Microsoft Flight Simulator X Service Pack 1. I´hope it work´s.
