***Important technical notes: In order to connect a SRXL2 remote satellite like SPM4650 it is necessary to interchange the plus and minus wires (usually black & orange) of the 4-wire receiver connector. In the configuration below you can directly plug in the receiver without the need for an extra adapter. Never connect the 4-wire receiver connector to MICROBEAST PLUS in wrong polarity! This will damage your receiver immediately! Check polarity at least twice before connecting the receiver to MICROBEAST PLUS. It is up to you to make sure polarity is correct as Beastx or Rotorquest do not assume any liability in case you do it wrong.
