The RX4R is a standalone receiver with all the functions of 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. The RX4R also supports the redundancy function, this means you can add another receiver as a back-up in case the first one fails. Last but not least, 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
• PCB protection with the comformal coating craftwork
