Freewing Flight Assistant APP is a professional mobile software used for setting, downloading, and updating parameters of aviation electronic devices. By using Freewing Blue Bridge as a signal transmission medium, a wireless connection is established between aircraft model electronic devices and mobile apps for remote unlimited operation. A centralized data exchange and setting platform can effectively reduce manufacturing and usage costs. The intuitive graphic and text settings interface of the Flight Assistant app enables us to set up, maintain, and upgrade devices more conveniently.
