FrSky Archer Plus SR8 Receiver

Introduction to the Archer Plus Series

The FrSky Archer Plus Series introduces enhanced receivers with improved anti-RF-Interference capabilities for more robust RF performance. These receivers support both ACCESS and ACCST D16 modes, intelligently matching the RF protocol during binding. The integrated Black-Box function allows for basic flight data logging, including power and signal status. The Archer Plus SR8, specifically, is a gyro-stabilized receiver featuring a built-in 3-axis gyroscope and accelerometer, offering multiple flight modes like Auto-level and Stabilization. It boasts full-range signal strength with dual detachable antennas for optimal reception and can be used in redundant systems via its SBUS In port. The FBUS protocol enables seamless pairing with other telemetry devices, simplifying build setups. Some advanced features require ACCESS and ETHOS compatibility.
