FrSkys' all in one receiver and 3-axis stabilizer.
Disclaimer - We consider this product to be complex to use and do not recommend it as your first FrSky receiver.
The FrSky S8R adds 3-axis stability to your winged aircraft. In addition to stabilizing standard planform aircraft, the receiver also can stabilize flying wings, as well as aircraft equipped with V-tails.
The S8R stabilizing parameters can be configured in the field using your FrSky transmitter or by connecting the S8R to your PC using the optional STK usb adapter. The S8R can also function as a typical 8 channel receiver by turning off stabilization.

NOTE: May not be compatible with very early Taranis radios. The newer Taranis Plus and all other FrSky transmitters are fine.
