Flying club

 

I think it's simply an absolute must have for any fan of general aviation.  If you get Flying Club X, you get four fixed wing and one rotary wing aircraft to fly, with great visuals inside and out.  The Cessna 152 uses custom panel gauges, and all feature a custom radio stack that replicates what would typically be found in that aircraft.  The aircraft also feature very realistic flight dynamics, and you also get a great little program called AeroTools which has various toys to play with to customise your Flying Club experience!  Not only does it feature a load and fuel editor for each aircraft, but also AeroPaint, which makes it easy to create custom liveries for the aircraft, AeroNation, which you can use to customise the registrations of the aircraft and also my favourite, AeroFace, which allows you to use either a webcam image or another digital photo of your (or anyone else's) face to superimpose onto the pilot figure that appears in the Flying Club aircraft.  This I have found is great fun to play with!

 

Plus, with the latest update, all the aircraft are compatible with FSX SP2, and have been reworked to take advantage of the new features this provides.

 

It's a must have product in my book!
