Mode 1 is available in the demo version.
To use mode 1 you go through the Calibrate Controller-procedure as using mode 1.
Keep an eye on what it says on the top of the calibration screen.
For example - when it says "throttle up" on the top of the calibration screen, you use the stick that you wish to use for throttle.
(In your case you would use the right stick)
An when is says "yaw left" you use the stick you wish to use for yaw etc...
(If you're using a touchscreen you can simply quick-select the mode you wish to use on the main menu)
