About this game
By Aviators, For Gamers


Acro FS is a stick-and-rudder aerobatic flight simulator created by Jim Bourke, airshow pilot and member of the US Unlimited Aerobatic Team. Designed from the ground up to accurately simulate aerobatic flight, it allows you to experience what it’s like to strap into a high-performance stunt plane and take to the sky. Take control of an aerobatic airplane, throttle up, and discover what you can do. There’s no navigation, no radios - just a lot of horsepower in a state-of-the-art aircraft.

Controller Required!


Acro FS requires a controller to fly. For good control, you'll need a 4-axis controller. A gamepad will work, as will "3D" flight sticks that include pitch, roll, yaw, and throttle. For best results, you can also use an RC-style controller that places these controls on two sticks, or muliti-USB systems with stick, throttle, and rudder pedals.

Controller Required
You'll want at least a 4-axis controller for flying Acro FS. At this point, all of those axes need to be on one controller - we don't support multi-USB configurations yet. We have provided profiles for: Our InterLink RC controllers Gamepads A couple of flight sticks If your controller doesn't work with any of these profiles, you'll need to set it up through the profile editor. Settings->Controller->Advanced will take you to the Controller selection page. From there, you can select the controller you want to use, and press the Edit button to edit the profile. Use the profile editor to assign controls to the numbered control channels, and optionally, the UI functions at the bottom of the list. Once you have a good working profile for your controller, consider sharing it. We'll set up a facility for users to send us profiles they've had success with. Watch for more information on that as we get it figured out.Read full article on Community Announcements (NoBeard)
