I had to reinstall FSX,to Fly this plane...for me its worth it..Its a fine plane to look at,and to Fly!!..it seems to be rare now as its no longer offered as far as I know...I would hope it could be adaptable to FS9...BUT??...so now I am back to a dual Flight Simulator...On,FS9 is all inclusive to date..my FSX?? its a One Plane sim!!...but for me its worth it....nice plane!!......Thanx Vin!
