Shutdown
FlySky FS-i6X don't have a software controlled shutdown button. Do not switch off radio when you see ▫ (small square) icon in top right corner of main screen. It indicates that settings are not yet saved. Wait until it disappears or use "Save all" option from main screen popup menu.
When to use "Save all" option:
- When you don't want to wait until square icon disappear before shutdown.
- With USB connected - when USB is connected then settings are not stored with standard delay.
- To save timers.
USB connection
FlySky FS-i6X don't have a USB VBUS making it impossible to detect USB connection. To connect press OK on main screen and select "USB Connect" (In version 1.8.0 or earlier it's in: Radio Setup -> "USB Detect").
Powering by 2S Li-Po/Li-ion/18650
FlySky i6X is officially rated for up to 6V. Running anything above will damage your radio.
Mode 1 & Mode 3 radios
With Mode 1 & Mode 3 radios you may experience inverted gimbal movement and swapped gimbals on main screen. To fix this swap gimbal connectors (red-white one with black-white one).
