FrSky RB35 Dual Power and Triple Receiver Redundancy Bus is an original FrSky product from the FrSky power and redundancy range family. This page is organized for practical buying decisions, with the fit, RF protocol, channel count, voltage, compatible accessories and installation role presented clearly.

It is suited for radio receiver installations for RC aircraft, helicopters, gliders and advanced telemetry setups. The information focuses on what an end customer needs to choose confidently, without exposing supplier pricing or directing the customer away from RC-MODEL.

Key Advantages

  • Built-in Power Switch Match with Different External Switches (Optional, like NFC, etc.)
  • The RB-35/RB-35S builds on the success of the previous trusted Redundancy Bus series by adding many new features, such as configurable dual power input, dual BEC outputs, overload / current detection, the new ADV stabilizer (RB-35S), etc. The RB-35/RB-35S system has been designed to meet the needs of users who want the ultimate flight-safe performance and safety for their RC Models.
  • Triple Receiver Redundancy & Dual Power Input
  • RB-35/RB-35S has been designed to offer both dual-power and triple-receiver redundancy. This provides the user triple receiver signal and telemetry redundancy by adding multiplex ports (RX1-3 IN / S.Port). Dual-power provides a safe and efficient way to power the system with your power sources connected via a pair of standard XT30 connections.
  • The dual-power consumption system can operate either in Balance or Backup mode. In Balance Mode (default), it consumes the power line from either power source depending on which has the higher voltage. When switching to the Backup Mode, the system consumes the power line with the priority that the user selected under the set voltage range.
  • Dual BEC Outputs & Overload Protection & Current Detection
