Flying Model Simulator:
"One of the biggest downfalls of FMS is that the RC Models and Sceneries that are included with the sim are really crappy. Both in looks and in the way the models perform. But there are many people who have taken the time to make sceneries and models that are much better then the originals. You can search 'FMS Downloads' on google to find places to download the additional models for free.
But I went ahead and made it a little bit easier for you. I took all my favorite FMS Sceneries and Models and saved them in one file that is available for free download. Here is the link to download them."
