Hi everyone, I searched this problem and there were a few hits. I've successfully calibrated the acceleration and compass but get blank bars when doing the Radio Calibration. The radio is bound to the RX and all servos work. I got HUD and GPS lock but can't proceed with initial setup without the radio calibration.
I'm using Pixhawk PX4
Taranis + 9XD (XJT module not yet installed)
Zeta Science FX79 Buffalo Flying Wing
One person who solved their problem reversed throttle on the radio. Not sure how to do this on the Taranis.
