This simulator requires a powerful device. You will get best performance if you select low resolution and low graphics quality on the main menu. Also, if possible activate "Performance Mode" or similar in your phone settings to get the best performance.

Note that this is a RC flight simulator, not a game. You might find that the controls are hard, but that's because it's made to mimic real life. It is highly recommended to use a good physical controller.

If your device supports USB OTG and you have the right cable you can try to use a USB gamepad/controller.
There is a free demo available that you can try to see if it works with your controller.
Physical controllers are configurable between mode 1,2,3 and 4.
There is no guarantee that the simulator will work with your device/controller. If you have any problems please send an email and I might be able to help.

Controllers that have been successfully used include FrSKY Taranis, Spektrum, Devo, DJI FPV, Turnigy, Flysky, Jumper, Radiomaster, Eachine, Detrum, Graupner and Futaba RC radios, Realflight and Esky USB Controllers, Logitech, Moga, Xbox and Playstation gamepads.
