The FrSky Archer Plus SR12+ is a premium 12-channel stabilized receiver designed for giant scale RC airplanes, turbine jets, aerobatic aircraft, and advanced fixed-wing applications. Featuring integrated 3-axis gyro stabilization, configurable channel ports, FBUS support, signal redundancy capability, and compatibility with both ACCESS and ACCST D16 transmitters, the SR12+ delivers exceptional flexibility and control for serious RC pilots.

FrSky Archer Plus SR12+ Stabilized Receiver

The Archer Plus series represents the next evolution of FrSky receiver technology, offering enhanced anti-RF interference capability, improved telemetry integration, flexible channel configuration, and advanced stabilization features in a compact and powerful receiver platform.

The SR12+ features a built-in 3-axis gyroscope and 3-axis accelerometer with multiple flight modes including stabilization, auto-level, and knife-edge support. This makes the receiver ideal for giant scale aircraft, turbine jets, warbirds, and precision aerobatic applications where additional flight stability and confidence are desired.

Each of the 12 configurable channel ports can be assigned as PWM, SBUS, FBUS, or S.Port, allowing highly flexible installation options and cleaner radio system layouts.

With FBUS support, the Archer Plus SR12+ integrates seamlessly with FrSky Xact servos, telemetry sensors, and other compatible devices while simplifying wiring and setup.
