The RX4R is a stand-alone PPM receiver with all the functions of the X4R. It features 4 PWM outputs with high precision and low latency. The PWM output latency is 9ms less than that of the X4R in high-speed mode. This tiny and light-weight rx also supports the FrSky redundancy function, meaning you can add another receiver as a back-up in case the first one fails. Finally, the RX4R and the whole "RX" line has a 40% increased operating range compared to the previous X series receivers.

Features: -

  • Small and High sensitivity (40% increase of the range compared to previous X series receivers)
  • Higher precision PWM and Low latency PWM output
  • Lower power consumption
  • Redundancy function supported
  • Smart Port enabled and telemetry data transmission supported
  • Battery voltage detection supported
  • 2 detachable IPEX 4 connector antennas
