I just got a new DJI A2 flight controller and I am using an FrSky X8R receiver with Sbus and I am getting a stick calibration error with the DJI Assistant software program. It looks like I setup the radio correctly and all the controls are responding on the screen and the mode control switch is working. Everything else looks good and I am using the latest firmware and software. I wish I had a transmitter that was compatible with the A2's internal Rx or a D-bus adapter so that I could see if other types of radios solve the problem. Does anyone have any ideas what I could do to fix the error?
