G'day there.. looking forward to getting stuck into AMS2.. I only run ACC at the moment and have roughly 2000 hours in AC/ACC.. After buying AMS2 today there were no major hiccups in the install/setup.. A couple of minor things however nothing worth crying over.. see you on the track..
Enjoy. Also take a look at the FFB megathread. Lots of helpful tips there. You may enjoy FFB out the box, in case you dont have a look at the suggestions.
