champion srs e futaba tx T18mz rx R7003 SB

  • sorry the questions is the first power box I buy

    I connected 2 R7003SB to the Sbus 2 port of the receivers and the system seems to work only with this port. now if I wanted to use a unisens SM telemetry system to which port of the rx can I connect it?

    I configured the volts both A and B with 7.4 the receivers are powered with what voltage?
