It is not easy to find a clean, convenient and economical solution for the drone that you are going to build: drone & gimbal control+videolink+datalink, especially when there are lots of options in the drone market. For example, nowadays the radio system has built-in telemetry, and the video link comes with datalink and radio control. Also, some suppliers declare that the video transmitter range can reach up to 15KM but the only 10KM.
After months of integration and test, we are proud to say that we can provide such a solution. In essence, you will only need one radio controller, one video&data link, and one laptop to control drone and gimbal, display video streaming from the gimbal, and handle data communication with the flight controller.
