Thank you for this video presentation! Exact fix for my F280 issue. Love you ❤😛 Before watching this, I tried to fix the problem clicking bind in the previous menu and ELRS receiver went flashing green to solid green. Fixed. But the flight controller was still flashing blue. Following your steps, changed to SBUS. Solid blue!! Fixed. Dont know how it changed to CRSF. Must have been me.
