BlackBird686 Hangar Idea works very well. The only problem with it, its that you need a lot Hard drive space to many different CFS2 install. With ACMan allows you to use all your planes in just one install. you can the same MB. All you need to do is change the Hangar and will have a new set of planes.
You use what ever method you like or suites you the best.
I do recommend that the download ACMan anyway just in case you would like to use it some time in the future.
I also reccommend that you download the ship Manager as well.
Remember there is also a limit of ships as well. You can manage them with the ship manager at:

Enjoy
