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. SR6 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.
Off: When the mode is activated, SR6 will transmit the received commands produced by the transmitter to the model without compen-
sating.
Stabilization: When the model is activated, SR6 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, SR6 will make the model return to level orientation with internal three-axis accelerome-
ter 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, SR6 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, SR6 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.

Overview
Introduction
The Archer SR6 are gyro-stabilized receivers with a built-in 3-axis gyroscope and 3-axis accelerometer, they have 6 high-precision
PWM channel outputs and features multiple flight modes and configuration methods. They support full-range signal strength with dual
detachable antennas it guarantees optimal antenna-reception and maximum range. In addition to all this, the SR6 can also be used as
a redundancy receiver along with any other FrSky ACCESS capable receiver equipped with an SBUS port.
All of the Archer receivers are hyper-matched with the ACCESS protocol. They not only feature wireless firmware upgrades and
increased range and telemetry performance, the SR6 now supports more functions like configurable telemetry power, S.Port/F.Port
switching and FLR output. Additional valuable features are under development to unlock the true potential of the ACCESS protocol.

Offset Angle Setting
Due to the possible errors in minor installation and calibration, the function is designed to adjust the attitude of the model. Thus, the
user could achieve the best orientation when Auto Level, Hover mode and Knife-edge mode is activated.
Note: Optional range is from -20° to 20°.
Offset Angle of Auto Level
The angle of roll and pitch could be adjusted on the channels related to aileron and elevator. Straight and Level flight could be realized.

Note: If the compensation direction is incorrect, please reverse the corresponding channel as illustrated below.
After changing the compensation direction, make sure to check it again on the actual model.
When the plane is rotated to left or right
(Yaw), rudders should have the correcting
actions as illustrated above.
Inspection of flight attitude
To ensure flight safety, checking the compensation direction of the model is strongly recommended.
Activating auto level mode will produce a strong deflection on AIL and ELE, which is used to check the response of aileron and elevator.
Also, activating Knife-edge and Hover mode will have the same reaction on the rudder.
When the plane is rotated left or right (Roll),
ailerons should have the correcting actions
as illustrated above.
When the plane is rotated up or down (Pitch),
elevators should have the correcting actions
as illustrated above.
Under identical operating conditions, the value of each channel produced by the assigned switch in FrOS are opposite
to that in OpenTX. For exmaple, SW Up in FrOS is equal to SW Down in OpenTX.
Never operate the stick bound to CH12 during flight session. If so, it will trigger self-check and may cause the crash
of the model.
Self-check
Attentions
• Before self-check, please place the model on the groud (level surface).
• When the model is flying, aerodynamic balance is more important than level attitude, which results in that the model flys at a constant
altitude with the nose slightly pointing up at low speed. To avoid the nose-diving of the model at high air speed, the user must insure
that the model is placed at a level or slightly-nose-up attitude during self-check.
• Always install SR6 straight and level in the model. If required, PC software could be used to adjust the angle of attack with the purpose
of realizing the required setting. If the values set by the user is bigger than average ones, we advise to recheck the installation
orientation of SR6.
Steps ( Different from the SXR/R9 STAB OTA/RB series)
• Turn on the transmitter and ensure that Ail (CH1), ELE (CH2), RUD (CH4), AIL 2(CH5) and ELE (CH6) are in the neutral position.
• Power on the model and start SR6 self-check. Ensure the auto level angle of the gyro and the neutral position of gimbal. Please don’t
touch/move the model until self-check finishes, or it may corrupt the calibration settings created during the procedure.
• Move the three-position sticks bound to CH12 three times in 2 seconds (up, mid, down). Then the BLUE LED will turn on. Waiting the
8~9 seconds, the LED will flash and move the sticks bound to CH1~CH6(except the CH related to Thr) in 7~8 seconds , the corresponding
parts on the model will move . At last, the BLUE LED will turn off,the corresponding parts on the model will move automatically，
indicating self-check has completed, In the end, SR6 will save the zero points of the gyro, auto level angle, gimbal neutral position
and servo channel limits.
• Move the sticks bound to CH1~CH6 (except the CH related to Thr) and check the channel output limits, ensuring that the signal outputs
of SR6 will not damage the corresponding parts on the model.
Setup
• Calibrate SR6 with the Lua.or Freelink App or the PC software and install it into the model. Insure the settings of wing type and
mounting type are identical to the intended model installation.
• Turn on the transmitter and reduce the value of servo endpoint setting. Ensure self-check mode will not damage the corresponding
parts on the model.
• Assign a knob/slider to CH9, then real-time gain adjustment capabilities of SR6 will be activated.
• Assign three-position switches to CH10 and CH11 with the purpose of switching available flight modes.
• Power on the model and check the deflection direction of each related parts on the model. Make sure the switch assigned to flight
modes is correct and the compensation direction of the gyro is set as intended on AIL, RUD and ELE.
• Make a self-check for SR6 if necessary. Disconnecting the power on SR6 will not lose the set parameters.

The positive and negative values related to three-axis gyroscope and accelerometer make a total of six values that need to be acquired.
Please follow the on-screen instructions.
• Click the “Calibration” button and wait until the YELLOW LED flashing, indicating the calibration on this orientation has been completed.
• Repeat the above step five times (remaining 5 dimensions). Placing SR6 in the required orientation, ensure all values (X, Y, Z, Mod)
are displaying 1.000 with the deviation of ±0.1.
• Press “Write” to save the data on SR6 when done.
