Hi, I am trying to build a quad with specific features that is under $400, if possible. I would want the quad to be fpv (with some kind helpful osd), able to have at least a 1 mile range, a return to home feature, 10-20 min flight time, and the ability to attach an action camera (sj8000). I'm very new to this hobby and am looking for help from someone who could walk me through a complete parts list, and provide advice on helping me build and setup this quad to be ready to fly. Any suggestions on where I could find this kind of help?
