Hello, Decided to build a quad!! My frame is a Geprc Mark 2-6, now I’m just shopping for the rest of the components. My first noob question is: Are the Camera and vtx necessary for the FC to function properly? I was wondering if I could fly line of sight in the beginning just to get the feel of everything and hopefully spare some damage to components, especially if I’m not using goggles right away. I wasn’t sure if the FC uses video at all to control flight. My guess is no, but I just want to be sure!
