FrSkys' all in one receiver and 3-axis stabilizer.
Disclaimer - We consider this product to be complex and do not recommend it as your first FrSky receiver.
The FrSky S6R adds 3-axis stability to your winged aircraft. In addition to stabilizing standard planform aircraft, the receiver can also stabilize flying wings as well as aircraft equipped with V-tails.
The S6R stabilizing parameters can be configured in the field using your FrSky transmitter or by connecting the S6R to your PC using the optional STK usb adapter. The S6R can also function as a typical 6 channel receiver by turning off stabilization.

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