5. About#

FS One by InertiaSoft is an RC flight simulator created by a dedicated group of RC modelers (and more people!).

InertiaSoft’s aim is to offer you the most realistic RC flight simulator. Our emphasis is on accurate aerodynamics and physics for airplanes. We hope you enjoy the level of RC flight realism.

We are improving FS One (since 2003), and we want it to keep going and growing.

When you download FS One, we hope it gives you many hours of RC sim enjoyment and practice. If you like it, please consider making a donation in the amount of your choosing.

Supporting its development will also bring more people into this great hobby.

Last, please help spread the word. Sharing FS One links and know-how is the best way to let your friends (old and new) discover FS One and find out how much it has to offer for free.
