This simulator requires a high end device.
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.

Supports first person view (FPV) and line of sight (LOS) flying.
Includes self-leveling and acro mode.
Option for low resolution mode (to be able to get higher framerate)

This is a demo with one scene only (the desert). The full version of FPV Freerider includes six sceneries and a lot of more setup options for rates camera and physics as well as a 3D flight mode for inverted flying.
The quad in this demo has deliberately rather sluggish settings in the full version you can tune it precisely to your liking.

Touchscreen controls support mode 1 2 3 and 4.
Mode 2 is default input:

Left stick - Throttle/Yaw
Right stick - Pitch/Roll

If the simulator doesn't work on your device it doesn't work simple as that. Most probably nothing to be done about it. Giving a low rating does not help.

If your device supports USB OTG and you have the right cable you can try to use a USB gamepad/controller for better control.
Physical controllers are configurable between mode 123 and 4.
There is no guarantee that it will work with your device/controller please try this free demo first to see.
