Building redundancy in to our RC systems not only makes them safer but also helps to protect our investments. The FrSky Redundancy Bus brings an added measure of insurance and reliability to the FrSky RC system. It gives us the ability to integrate dual receivers and dual power supplies into our control systems. The result is then, that the Redundancy Bus (RB) has a spare control signal and a spare power supply to rely upon in the event of a malfunction. The RB also supports the S.Port telemetry system and its sensors as well as SBUS. Last but not least the RB monitors all 16 servo output channels for over current and over voltage conditions, and will limit those outputs to protect your servos in the case something goes awry.

The Redundancy Bus comes with two, six pin power connectors and shrink tubing. Wiring the power connectors is pretty simple. If you look closely at the top of the supplied plugs you will see the plus and minus symbols for positive and negative polarity. Simply insert your power wire into the centre of the three pins of either the plus or minus side and solder all three pins to that wire. The plugs are keyed so you cannot accidentally plug them in backwards. See the product photos to see an example of what these should look like.
