FrSky ARCHER SR10 PRO Receiver for RC Drone Model Instruction Manual

Version 1.0

Introduction

The Archer SR10 PRO are gyro-stabilized receivers with a built-in 3-axis gyroscope and 3-axis accelerometer, they have 10 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 SR10 PRO can also be used as a redundancy receiver along with any other FrSky ACCESS capable receiver equipped with an SBUS port. The SR10 PRO 10-channel receivers’ noticeable features are its Anti-vibration performance and dual-battery ports for redundancy.

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 SR10 PRO now supports more functions like configurable telemetry power, S.Port/F.Prot/F.Port 2.0 switching and FLR output. Additional valuable features are under development to unlock the true potential of the ACCESS protocol.

Overview

Warning: Do not plug the additional power supply in other port (Channel, S.Port, SBUS, etc.) while using dual battery to power the receiver.

Set up your model and receiver

You need complete calibration of Accelerometer about the six positions via the STAB RX.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 (STAB RX.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.

Note: The default mode of SR10 PRO is Quick Mode. When re-flashing firmware of SR10 PRO 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

The model types could be enabled via STAB RX.Lua/FreeLink APP/FreeLink.exe). If required, SR10 PRO could be used as a standard 10 channel receiver.

Conventional model

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

Delta wing & Flying wing & V-tail

The available flight modes can be assigned to CH10 with a three-position switch.

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. SR10 PRO 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, SR10 PRO will transmit the received commands produced by the transmitter to the model without compensating.

Stabilization: When the model is activated, SR10 PRO 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, SR10 PRO 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, SR10 PRO 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, SR10 PRO 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.

Configuration parameters

The configuration parameters are listed on the top of the interface: Wing type, Mounting Type, Gain Setting, Offset Angle Setting, Accelerometer Calibration

Wing Type

Options of wing types:

Wing_Rud_Ele_Ail——conventional modelWing_Delta_Ail/Wing_Flying—— Delta/Flying wingWing_Vtail_Ail——V-Tail

AUX1: If selected, AIL2 function will be disabled on CH5

AUX2: If selected, ELE2 function will be disabled on CH6

Mounting type

Level, Buttom, Right and Left up options are available.

Gain Setting

The first part

Compensation direction: selecting the travel direction of AIL, AIL2, ELE, ELE2 and RUD. “＋” means positive and “－” means negative.

The second part

Gyro gain: Stabilization Mode

The gain setting under stabilization mode chould be set on the channels related to aileron, elevator and rudder.

Angle Gain: Auto Level Mode

The gain setting under automatic level mode could be set on the channels related to aileron and elevator.

Angle Gain: Hover Mode

The gain setting under hover mode could be set on the channels related to elevator and rudder.

Angle Gain: Knife Edge Mode

The gain setting under knife edge mode could be set on the channels related to aileron and rudder.

Note: Optional range is from 0 to 200%. 0, 1, 2 refers to 0%, 100% and 200% respectively.

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.

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.

Offset Angle of Hover

The nose-up angle could be adjusted on the channels related to aileron and elevator. Stationary hover could be realized in calm weather.

Offset Angle of Knife Edge

The angle of aileron and rudder could be adjusted on the related channels. Straight and level knif-edge flight could be realized.

Note: Optional range is from -20° to 20°.

Accelerometer Calibration

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 SR10 PRO 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 SR10 PRO when done.

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.

When the plane is rotated to left or right (Yaw), rudders should have the correcting actions as illustrated above.

After changing the compensation direction, make sure to check it again on the actual model.

Note: If the compensation direction is incorrect, please reverse the corresponding channel as illustrated below.

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 SR10 PRO 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 SR10 PRO.

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 SR10 PRO 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, SR10 PRO 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 SR10 PRO will not damage the corresponding parts on the model.

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.

Setup

  • Calibrate SR10 PRO 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 SR10 PRO 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 SR10 PRO if necessary. Disconnecting the power on SR10 PRO will not lose the set parameters.

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.
