FrSky Archer Plus R6L ACCESS / ACCST D16 Receiver
The FrSky Archer Plus R6L is a compact, full-range 6-channel receiver designed for pilots who need dependable FrSky control, telemetry support, flexible signal connections, and a clean installation. Its lightweight 5.6g design makes it a strong choice for sport aircraft, park flyers, gliders, foam aircraft, electric models, and other fixed-wing builds where space and weight are important.
The Archer Plus R6L supports both ACCESS and ACCST D16 protocols, providing compatibility with a wide range of FrSky 2.4GHz transmitters and RF modules. The Archer Plus Series features enhanced anti-RF interference performance and smart protocol matching during binding, helping provide a stable and dependable radio connection.
The R6L features six standard 3-pin PWM channel outputs for straightforward servo and ESC connections. Additional functions are available through its SBUS In, SBUS Out, S.Port, FBUS, and analog voltage-sensing connections. The included connector adapter cable allows these ports to be configured for different aircraft installations and receiver redundancy setups.
When used in ACCESS mode with a compatible FrSky ETHOS transmitter, the receiver supports Over-The-Air firmware updates, configurable telemetry power, and protocol switching between S.Port, F.Port, and FBUS. When configured for FBUS operation, compatible telemetry sensors, servos, and control devices can communicate through simplified wiring, and the receiver can provide up to 24 signal channels.
Compatibility Note
The Archer Plus R6L is compatible with and can bind to all FrSky ECOS, TWIN, and Tandem Series radios that support ACCESS or ACCST D16 protocols. This includes compatible transmitters and RF modules operating in either supported protocol mode.
Some advanced functions, including OTA firmware updates, configurable telemetry settings, protocol switching, and FBUS device configuration, require a compatible ACCESS and ETHOS system.
The Archer Plus R6L is not a TWIN TW receiver, Tandem TD receiver, ELRS receiver, Spektrum receiver, Futaba receiver, or FlySky receiver. Use this receiver only with compatible FrSky ACCESS or ACCST D16 radio systems.

Select the Correct RF Protocol
Create or open the aircraft model on your FrSky transmitter and select either ACCESS or ACCST D16 to match the receiver firmware and intended operating mode. ACCESS is recommended when supported because it enables additional receiver features.
Binding
Place the transmitter into registration or binding mode for the selected protocol, then power the receiver and follow the current FrSky binding procedure for your transmitter and firmware version.
PWM Connections
Connect standard servos, the ESC throttle lead, retracts, lights, or other PWM-controlled accessories to the six 3-pin channel outputs. Verify signal, positive, and negative wire orientation before powering the receiver.
SBUS Out
Use SBUS Out when connecting the receiver to a compatible flight controller, stabilization system, channel expander, decoder, or other SBUS device.
SBUS In and Receiver Redundancy
SBUS In may be used with a compatible secondary receiver or redundancy system. Confirm that the secondary receiver, signal format, power arrangement, and receiver settings are compatible before flight.
Telemetry and FBUS
The multifunction telemetry connection can be configured for S.Port, F.Port, or FBUS operation with a compatible FrSky system. FBUS allows compatible control and telemetry devices to share simplified wiring.
External Voltage Monitoring
The AIN2 connection supports external battery or device voltage measurement from 0–35V when used with the correct 1:10 voltage divider. Do not connect a flight battery directly to AIN2 without the proper voltage divider or approved voltage-sensing cable.
Antenna Installation
Keep the antenna element straight and away from carbon fiber, batteries, ESCs, motors, ignition systems, high-current wiring, and other conductive materials. Do not sharply bend, pinch, cut, or modify the antenna.
Firmware Compatibility
Before binding, confirm that the transmitter RF firmware and receiver firmware support the same ACCESS or ACCST D16 version. Firmware mismatches can prevent binding or cause features to operate incorrectly.
Preflight Check
Confirm correct channel movement, servo direction, failsafe behavior, telemetry operation, and control response before flying. Complete a range check after installation and whenever the receiver, antenna placement, transmitter configuration, or aircraft electronics are changed.
