The Redundancy Function

For the master and slave receivers, when the master receiver goes into failsafe, the output signal from the slave receiver will be used until the master receiver works again.

Note: When both the master and slave receivers go into failsafe, the failsafe signal from the master receiver will be output; The slave receiver should be in no telemetry mode.
