If you go to the FliteTest YouTube page look for the xHover build. TJ does a great job showing how to get the proper drivers installeed and how to configure BetaFlight. It is toward the end of the video. If you watch the whole thing you will learn a lot about ESCs, PDBs, Flight Controllers, and testing for proper voltages. I built my first quad by following TJ's instructions. It works great. My ability to fly it is still in question.
