Channels

Channel No.	Corresponding parts on the model	Full name
CH1	AIL 1	Aileron
CH2	ELE 1	Elevator
CH3	THR	Throttle
CH4	RUD	Rudder
CH5	AIL 2	Aileron
CH6	ELE 2	Elevator
CH7	User-defined
CH8	User-defined
CH9	Receiver Internal Use	Gyro gain adjustment
CH10&CH11	Receiver Internal Use	Flight modes
CH12	Receiver Internal Use	Self-check activation switch

Note:

Only S8R has CH7 and CH8 PWM outputs.

When the the value of CH9 is in the center, the Gyro gain is zero. The gain increases as the value gets bigger. Until the value is ±100%, the gain reaches maximum.

CH9 uses absolute values ( or ). For example, 70% is seen the same as 70%. Use the edit line below in the transmitter mixers to remedy this.

CH9 Edit — Setting CH9 at Weight 50 and offset 50, the assigned pot/slide will work normally.

Instruction manual for FrSky S6R&S8R (SxR)

Quick Mode

Quick Mode is mainly designed for beginners. It supports normal model only, suitable for stabilization mode, manual (six-axis off) mode, automatic level mode and configured through CH10. What’s more, an urgent mode is added to configure automatic level mode default through CH12. The precise configuration is written below.

Channel	Position	Flight Mode
	SW Up	Automatical Level Mode
CH10
	SW Mid	Stabilization Mode
	SW Down	None
CH12	SW Down	Urgent Mode (Automatic Level Mode)

Note: The default mode of SxR is Quick Mode. When re-flashing firmware of SxR or replacing with a new one, the preset mode will be cleared out, that is to say, SxR will be in Quick Mode.

-- If Quick Mode is applied, there is no Knife Edge or (3D) Hover mode.

--CH11 is not used when using Quick Mode.

--Under identical operating conditions, the value of each channel produced by the assigned switch in FrOS are opposite to that in OpenTX. For example, SW Up in FrOS is equal to SW Down in OpenTX.

Flight Mode

Off: When selected, SxR will behave as a normal receiver without any compensation.

Stabilization: When selected, SxR will compensate against external forces (wind) to enhance stability. This function is used to enhance the stability of the model on three axes (Pitch, Roll, and Yaw). CH9 could be used to provide gain control by assigning a pot or a slider, changing the sensitivity of the internal three-axis gyroscope.

Automatic level: When selected, SxR will make the model return to level flight with internal three-axis accelerometer and three-axis gyroscope on AIL and ELE channels after the sticks being released to neutral. Automatic RUD channel works in stabilization mode only.

Hover: When selected, SxR will orientate the model’s nose straight up. The mode uses three-axis accelerometer and three-axis gyroscope and RUD, ELE for control.

Note:

ELE and RUD control is automatic. Under this mode, AIL controls the model rotation and THR adjusts the height. Automatic AIL only works on stability, auto level and knife-edge mode.

Knife-edge mode: When selected, SxR will roll the plane on a certain side (wing points up) with internal three-axis accelerometer and three-axis gyroscope on RUD and AIL Steering is done with ELE, altitude will be maintained with THR/RUD. Automatic ELE only works on stabilization, auto level and hover modes.

	Model Type	Mode
		Automatic level
	Normal Model	Stabilization
		Hover
		Knife-edge
		Off

	Automatic level
Normal model (Quick Mode)
	Stabilization
	Off
	Automatic level
Delta Wing(Elevon)/Flying Wing/V-tail	Stabilization
	Off

Note: These model types are selected through SxR, PC Config or SxR.lua.

Normal Mode

Layout of Normal Type

The available flight modes can be assigned to CH10 and CH11 with three-position switches.

Instruction manual for FrSky S6R&S8R (SxR)

	Flight mode	Stabilization	Auto Level	Off
	CH10	CH10>M+H	CH10<M-H	CH10 SW Mid
		(CH10 SW Down)	(CH10 SW Up)

When Delta wing (Elevon)/ Flying wing/ V-tail is selected, there must be no active mixing on the transmitter. SxR must mix all of the AIL (CH1) and ELE (CH2) signals internally. CH4~CH8 is user-defined.

M: represents a neutral signal period (1500μs/ 0.0%/ Mid position).

H: represents the minimum time of required signal (50μs), or to make state/mode change. If the value of Mid position is

1500μs, then Low position is from 1000μs to 1449μs, High position is from 1551μs to 2000μs.

Note:

When factory settings are used, switch positions above represents corresponding required mode, or just follow the vision in brackets to set the required switch positions for each mode.
