Hello! Thanks to those who on another occasion told me how to link the ST16 with another Typhoon H that is not the one that was purchased as it collided. I was able to make the link, only that the Drone is presenting a whistle or sound that does not stop once I turn it on. All camera controls work. But I have not yet made the compass or of course any flight for fear that I will not be able to control the drone. I turn it off and turn it on at home and the deafening noise follows. Does anyone know what may be happening? Please!
