Unfortunately the communication protocol of the AR9020 receiver is not fully compatible to the SRXL specification. We can provide a MICROBEAST PLUS firmware with modified Spektrum SRXL protocol so that the AR9020 receiver's SRXL output can be used anyway. You can request the firmware at our service center. When using this firmware it is not possible to use receivers from Multiplex-RC with SRXL V2 signal output, neither is it possible to use Spektrum receivers that are compliant with SRXL standards. Otherwise this modified firmware does not differ from the default firmware.
