FrSky RX4R
Post added on July 22, 2019
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.
Number of Channels: 16CH (1-4CH PWM from conventional channel outputs, 1-16CH from SBUS OUT port)
