I was connected Radian to the S-BUS port of New Futaba R7008SB Receiver. This receiver is the specification of the new 2.4GHz FASSTest to support S-BUS2. It did not work unfortunately. S-BUS2 is a two-way communication for telemetry. I changed the Receiver setting to original S-BUS mode is not necessary since S-BUS2 in Radian. I was the same as the results. Do you support the S-BUS2 Radian?
