SKY_WIFI is an Android application that allows users to remotely control their four-axis aircraft using their smartphones. This app is developed by JOYHONEST and is available for free on the Google Play Store.

One of the main features of this app is that it enables users to view real-time video footage taken by the camera on the aircraft. The video data is transmitted via 2.4G Wifi Protocol, ensuring a clear and stable connection. Additionally, users can take photos and record videos directly from their phone while controlling the aircraft.

Overall, SKY_WIFI is a useful app for anyone who owns a four-axis aircraft and wants to control it from their phone. The video transmission is reliable and the ability to take photos and videos from the app is a nice touch. However, it's important to note that this app only works with four-axis aircraft and is not compatible with other types of drones or RC vehicles.
