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 Gyro gain adjustment

CH10&CH11 Flight modes

CH12 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.

Receiver Internal Use

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:

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:

gyroscope on AIL and ELE channels after the sticks being released to neutral. Automatic RUD channel works in stabilization mode only.

Hover:

gyroscope and RUD, ELE for control.

When selected, SxR will compensate against external forces (wind) to enhance stability. This function is used to enhance

When selected, SxR will make the model return to level flight with internal three-axis accelerometer and three-axis

When selected, SxR will orientate the model’s nose straight up. The mode uses three-axis accelerometer and three-axis

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.

CH10

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.

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

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.
