My F450 build was really going well, and then....... I am using a [both new] v1.1.1 TX and the dual antenna RX. And I have it set to D Bus in the assistant. The bind process goes to plan and I get a solid green on the RX. Three strange things- 1/ The main LED flashes a continuous orange [ meaning TX connection lost ] 2/ The assistant is not showing any connection 3/ If I power down and reboot the Naza, the RX goes back to flashing green. Ideas please.
