Hello. I am looking into getting a quad-copter and flying FPV but I am a little confused. I am thinking about getting the quad from this video (https://www.youtube.com/watch?v=GKz6KVGrjmI) and modifying it to do FPV with the camera setup from this video (https://www.youtube.com/watch?v=nt6kYWbMQIM). I am trying to find a receiver that would work with mini FPV setup for cheap. What receiver would you recommend. How would I set up the receiver with the camera? Do you know a cheaper alternative to the camera used in the micro FPV video. Thanks.
