FrSky RX4R 16 channel receiver with redundancy

The RX4R is a stand-alone receiver with all the features of the old X4R and has 4 PWM outputs with high precision and low latency. The PWM output latency is 9 ms less than the X4R in high speed mode. The RX4R also supports the redundancy function. This means that you can add another receiver as a backup in case the first one fails. Last but not least, the RX4R and the entire RX line have a 40% greater range than previous X-Series receivers.
