Unzip the zip file (mine is right click on the zip, click extract) I keep my planes in folder of their own in "my documents", but you can add them to the FMS models files, it is in program files on my computer. When in the game, load model, double click folder w/ planes, double click plane you want you should see a file that ends in .par (FMSplane.par)double click the par file (mine doesn't work if I push open I have double click for some reason) hope this helps BTW I have 250 planes at least , I lost count when I tried to count them last When playing go to simulate and push options, click the box that says auto-initialization after crash and the planes will bounce in stead of just stopping, It is great! FMS is the best(I mean for money dollar for dollar) Do you have a interface so you can use your tx?
