I am having issue binding my new Mimic to a Movi M15 with latest firmware. I defined the the MOVI CONTROLLER option on the app and tried to link my Spektrum receiver to it using various channels. No go. Do I need the RP-SMA or can I bind directly with the hardware that I have? I've also read that only Mimic Beta is compatible with the M series. Is it possible to downgrade the Mimic firmware to accomplish this on new hardware? Any help is appreciated!
