Note: Please do not do the binding operation in the near range while the firmware upgrading in progress.

Note: Update the firmware after the receiver getting registered (OTA).

Go to the [File manager], and select the FW, press the enter button, select [Flash RX by int.OTA]. Power on the 

receiver, select the RX, go to the [ENTER], complete the flash process, the transmitter will display [Success]. 

Wait for 3 seconds, the receiver works properly at the moment.

About OTA function (ACCESS mode)

How to switch SBUS channel mode

Enter into RX Settings, click [SBUS], then select SBUS-16 mode or SBUS-24 mode.

A pre-flight range check should be done before every flight, in case the signal loss is caused by the reflection of 

the signal by the nearby metal fence or concrete, and the shading of the signal by buildings or trees during the 

actual flight. Under normal circumstances, in Range Check mode, the RSSI at 150m is about 45-50.

1. Place the model at least 60 cm (2 feet) above the non-metal contaminated ground (such as on a wooden   

    bench). The receiving antenna should be in a vertical position.

2. Ener the ETHOS system, move to the "RF System", scroll the Encoder to select "RANGE" mode and press 

    Encoder. In range check mode, the effective distance will be decreased to 1/30.

Range Check

There are 3 failsafe modes when the setting is enabled: No Pulse, Hold, and Custom mode.

●  No Pulses Mode: On loss of signal, the receiver produces no pulses on any channel. To use this mode, select 

    it in the menu and wait 9 seconds for the failsafe to take effect.
●  Hold Mode: The receiver continues to output the last positions before the signal was lost. To use this mode, 

    select it in the menu and wait 9 seconds for the failsafe to take effect.
●  Custom Mode: Pre-set to required positions on the lost signal. Move the cursor to the failsafe mode of the 

    channel and press Encoder, then choose the Custom mode. Move the cursor to the channel you want to set 

    failsafe On and press Encoder. Then rotate the Encoder to set your failsafe for each channel and short-press 

    the Encoder to finish the setting. Wait 9 seconds for the failsafe to take effect.

How to set Failsafe

Note: 

● 

If the failsafe is not set, the model will always work with the last working status before the signal is 

   lost. That could cause potential damage.

● 

When the failsafe is disabled on the RF module side, the failsafe set on the receiver side will be 

   applied.

● 

SBUS port does not support the failsafe setting in No Pulses mode and always outputs signal. 

   Please set "Hold" or "Custom" mode for the SBUS port.

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.

Off: 

When the mode is activated, 

S

R10+ will transmit the received commands produced by the transmitter to the 

model without compensating.

Stabilization: 

When  the  model  is  activated, 

S

R10+  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, 

S

R10+ 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, 

S

R10+ 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, 

S

R10+ 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.

1. When Delta wing/Flying wing is selected, the signal produced by the transmitter should be without active mixes 

    on the channels related to AIL and ELE. SR10+ will mix the AIL(CH1) and ELE(CH2) input signal with a fixed

    mix percentage automatically. 

2. When V-tail type is selected, the signal produced by the transmitter should be without active mixes on the 

    channels related to ELE and RUD. SR10+ will mix the ELE(CH2) and RUD(CH4) input signal with a fixed 

    mix percentage automatically. 

How to switch the S.Port/SBUS OUT/SBUS IN/FBUS

Select  the  FBUS/S.Port/SBUS  Out/SBUS  In  for  the 

channel ports.

Enter into the [Set] of receiver.
