Lessons learnt from building a quadcopter

  • If you’re bad at soldering (like me), make a wiring loom instead of using a power distribution board, it’ll be easier to solder (I’m presuming!).
  • Don’t cut your wires too short
  • Make sure you know which way the motors are going to spin, and which way your flight controller wants them to spin, before you do any soldering. Looking at your motor and ESC from the top,  if you solder the wires straight from the motor to the ESC the motor will spin anti clockwise. To get it to spin clockwise just cross over any two of the wires.
  • If you use the CC3D flight controller, mount it so the USB port is facing sideways for easy access, then inform the Ground Station Software of this change
  • Learn how to bind your Tx to its Rx early in the build, you can use the power from an ESC rather than buying a binding battery
  • Don’t impulse buy, read a lot and learn before making the wrong purchase
  • If your ESC’s have linear BEC’s onboard, then you don’t need to cut the power from any of them before connecting the your flight controller

You should definitely buy William Gibson’s excellent glimpse into the future “Neuromancer”, you should also listen to Gibson himself reading the book. You’ll need to buy the book as reference if nothing else, some of the amazing ideas and concepts are flicked over so quickly, the book will allow you to pause, read and absorb them.
