Conventional model

Layout

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

	Flight mode	Stabilization	Automatic level	Hover	Knife-Edge	Off
	CH10 (3 pos SW)	CH10>M+H	CH10>M+H	CH10>M+H	CH10<M-H
		(CH10 SW Down)	(CH10 SW Down)	(CH10 SW Down)	(CH10 SW Up)	CH10 SW-mid
	CH11(3 pos SW)	M-H<CH11<M+H	CH11>M+H	CH11<M-H	M-H<CH11<M+H
		(CH11 SW Mid)	(CH11 SW Down)	(CH11 SW Up)	(CH11 SW Mid)

Delta wing & Flying wing & V-tail

Layout of Delta wing / Flying wing				Layout of V-tail
The available flight modes can be assigned to CH10 with a three-position switch.
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/Flying wing/V-tail is selected, the signal produced by the transmitter should be without active mixes on the channels related to AIL and ELE. S6R/S8R will mix the AIL(CH1) and ELE(CH2) input signal with a fixed mix percentage automatically. Signals on CH4~CH8 will behave as required by the user.

M: represents a neutral signal period (1500μs)

H: represents the time of required signal change to activate the mode (50μs). When the factory settings are selected, the switch position shown above represents the required modes.

Flight mode:

Off: When the mode is activated, S6R/S8R will transmit the received commands produced by the transmitter to the model without compensating.

Stabilization: When the model is activated, S6R/S8R will compensate with external forces (wind) as soon as receiving commands from the transmitter. This function is used to enhance the stability of the model on three axes (Pitch, Roll, Roll). CH9 could be used to adjust gyro gain by assigning a knob or a slider, changing the sensitivity of the counteracting signal produced by the internal three-asis gyroscope.

Automatic level: When the mode is activated, S6R/S8R will make the model return to level orientation with internal three-axis accelerometer and three-axis gyroscope on AIL and ELE channels after the sticks being released to neutral. RUD channel works in stabilization mode only.

Hover: When the mode is activated, S6R/S8R will make the nose of the model straight up with internal three-axis accelerometer and three-axis gyroscope on RUD and ELE channels (ELE and RUD inputs are not required). Under this mode, AIL is used to control the rotation of the model and THR adjust the altitude. AIL channel works in stabilization mode only.

Knife-egde mode: When the mode is activated, S6R/S8R will roll the plane on a certain side (wing points up) with internal three-axis accelerometer and three-axis gyroscope on RUD and AIL channels.Thus, AIL inputs are not required. While the mode steering is done with ELE, altitude will be maintained with THR/RUD. ELE channel operates in stabilization mode only.

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

Note: CH9~CH12 are not marked on the diagram.

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

Attentions

CH1~CH8 should be connected to the corresponding servos.

S.Port could be used to update, edit parameter settings via FrSky STK PC tool and connect with telemetry sensors.

Binding Procedure

Binding is the process of uniquely associating a particular receiver to a transmiter/transmitter module. A transmiter/transmitter module can be bound to multiple receivers (not to be used simultaneously). A receiver can only be bound to one transmiter/transmitter module.

Follow the steps below to finish the binding procedure.

1 Put the transmitter/transmitter module into binding mode

1.1For Taranis X9D Plus 2019 as an example,turn on the radio, go to the MENU – MODEL SETUP – PAGE 2, choose Internal or External RF, choose the [mode] ACCST D16 and select BIND.

1.2For Horus X10 Express as an example,turn on the radio, go to the MDL – INT MODULE or EXT MODULE, choose the [TX RF Protocol] ACCST D16 and select BIND.

1.3For transmitter module (XJT as an example), turn on the transmitter while holding the FS button on the module, release the button and the RED LED on XJT module flash.

2 Connect the battery to the receiver while holding the F/S button on the receiver. The RED LED on the receiver will flash, indicating the binding process is completed.

3 Turn off both the transmitter and the receiver.

4 Turn on the transmitter and connect the battery. The GREEN LED on the receiver indicates the receiver is receiving commands from the transmitter. The receiver/transmitter module binding will not have to be repeated, unless one of the two is replaced.

Note: After binding procedure is completed, recycle the power and check if the receiver is really under control by linked transmitter.

Set up your model and receiver step by step

You need complete calibration of Accelerometer about the six positions via the S6R/S8R.Lua/FreeLink APP/FreeLink.exe firstly. Step1: Connect your servos follow the channel list according to your model.

Step2: Set you radio follow the channel list.

Step3: Choose the Wing Type via the configuration tool (S6R/S8R.Lua/FreeLink APP/FreeLink.exe). Step4: Choose the AUTO LEVEL mode, check the model servo feedback.

Step5: Choose the manual mode, check servo feedback via transmitter.

Quick Mode

It supports stabilization mode and manual (six-axis off) 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 Down	None
CH10
	SW Mid	Stabilization Mode
	SW Up	Automatical Level Mode
CH12	SW Down	Urgent Mode (Automatic Level Mode)

Note: The default mode of S6R/S8R is Quick Mode.When re-flashing firmware of S6R/S8R or replacing with a new one, the preset mode will be cleared out.

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

-CH11 is not used when using Quick Mode.

Modes

		Stabilization
				Delta Wing
	Conventional Model	Automatic level			stabilization
				Flying Wing
		Hover			automatic level
				V-tail
		Knife-edge

The model types could be enabled via Freelink.exe or S6R/S8R.Lua. If required, S6R/S8R could be used as a standard 6/8 channel receiver.
