This setup adds another receiver to provide receiver redundancy. The second receiver is also bound to both Tx modules.

You use a (typically larger) “primary” receiver (R7 though R18) bound in Normal mode to both Tx modules. All servos are plugged into this receiver. You then set up a second receiver (typically an R3 through R6) as a satellite. The satellite is first bound to both Tx modules and is set as a clone with its failsafe turned off. The satellite receiver provides a continuous PPM stream unless it completely loses signal reception at which point the PPM stream stops. A male-to-male servo connector is used to connect the clone’s PPM out port to the primary receiver’s Sat port.

Setup Notes: During the setup, you have to tell the primary receiver to expect PPM data at its Sat port. Also, since the clone doesn’t transmit telemetry data (including the signal strength at its antennas) you’ll want to set up an alarm in the primary receiver to let you know if the PPM stream from the satellite stops (which means the satellite receiver has lost signal)

This setup has the primary receiver watching both Tx modules and provides datalink and antenna strength on the primary receiver only. The clone is also watching both Tx modules but remains in the background giving PPM signal backup to the primary receiver. While you can’t see the antenna strength of the clone, you still know it is functioning since there is an alarm if its PPM signal stops.

Pros:

• receiver redundancy
• antenna diversity (you now have four antennas)
• both receivers are each connected to both Tx modules (quad redundancy?)
• you can plug more than one battery into one or both receivers

Cons:

• added cost of second receiver (not too bad as R3 to R6 receivers are inexpensive)
• there is no isolation between multiple batteries plugged into the receivers
• one receiver is in clone mode so it doesn’t transmit telemetry data including its antenna signal strength.
• a bit tougher to set up as you have to bind the clone to both Tx modules in a separate procedure.
• can’t use the EXT port of the satellite (clone) receiver to plug in sensors.

This setup has the primary advantage that both receivers are each bound to both Tx modules. The primary disadvantage is that you can't see the signal strength of the antennas on the clone receiver (although you do have an alarm is the clone loses signal).
