Pictures of finished quadcopter

This tutorial is a step by step walk through of building an FPV racing quadcopter with the latest and greatest parts from 2017 (specifically for the Northwest Spec Class).  It is geared towards those who have never built a quadcopter and does not assumes you already have anything. 

Prerequisites

1) Learn the basics of soldering.  Learning to solder isn’t hard and this can be your first soldering project, but plan to spend a little bit of time practicing to solder on some wires you don’t need before doing this build.

2) Learn the basics of line of sight (LOS) flying.  Before you fly a fast racing quadcopter you should practice with a small toy or on a simulator. 

Here’s a cheep toy that you can learn the basics on:

Also I recommend getting a protector for it:
