Real Flight 3.5 (T-Rex 500) Installation

[Pipes]

I just git a Real Flight 3.5 Sim. I want to be able to load from the Knifeedege to my computer so that I can transfer the files and have the program for the T-Rex 500 in the menu on the Real Flight when I scroll down and see the diff aircraft. I tried to import three files from my folder to the Aircraft menu but it doesn"t show there. I have Windows Vista program. Can someone give instrustions on how to download and transfer ?
I am not too good with the computer. I need very basic steps.
Thanks
Newbie

From the Knife Edge website locate the TRex 500 page. Right click the link next to where it says "File". Choose Save Target As and save it to your Desktop.

Open RealFlight. From the top menu choose Simulation, Import, G3X. Locate the file you saved to your Desktop and open it. After a short moment the heli will be imported into RealFlight and you can see it in the Aircraft menu.

It works the same way for new fields as well. Hope that helps!
