The RX8R from FrSky offers the same reliable and trusted functionality as the original X8R. The difference is that the RX8R supports the redundancy function for master and slave receivers. The master receiver receives the SBUS signal from the slave receiver. The master receiver must be the RX8R, whereas, the slave receiver can be any brand receiver with SBUS output. For example, FrSky X9R, X6R, X4RSB, XSR, XM, XM+, RX*R, and the L9R.


Both the master and slave receivers receive the signal from the transmitter. When it is functioning correctly, the PWM output comes from the master receiver. Should the master receiver go into failsafe, the PWM output will instead come from the slave receiver. Should the master receiver begin functioning correctly again, the PWM output switches back to being sent by the master receiver.
