Chapter 13. Construction and Tuning

We’ve been through several chapters now getting the pieces ready. We’ve been putting together flight control software, starting from the aerodynamics. We have built a controller to run it on, from power distribution to motor controllers. Now it’s time to put it all together into a drone.

Install the Controller and Connect the LEDs

Getting inside the Syma X5 case means removing a lot of little screws, but they do give it strength when it’s all put together. Once inside, unscrew the existing controller and cut all the LED and motor wires. Now screw in our new controller with the USB port facing the back where the battery goes in. Next, solder the existing LED wires to the new LED pads on each side of our circuit ...
