hi everyone i am a newbie out here pls help me outi am designing a control system for a quad rotori have not studied any basics about control systems can ne 1 guide me how to go bout itthanks in advance
Read more…I have been thinking of ways to increase the range of the data modem or video feed from a UAV. And it always comes back to having better directional antenna on the ground that has to be pointing at the UAV. My problem is I don’t know too many people
