Futaba 18MZ single or dual receiver selection

  • Using 2 7008 or 7003 receivers with the Mercury for redundancy. Do I select “single” or “dual” receivers in the transmitter? I currently have single selected and both receivers linked to the tx and everything works fine. Using the “dual” rx option designates one as the primary. My thought is by selecting the single rx option, the PB will see them both as primary. Is this correct thinking or does the PB Mercury only use one rx at a time?
