Step 12:
Now it's time for the wiring harness. Here's what needs to happen: each of the four power and ground wires from the ESCs need to converge on a single, wider wire,
which will be hooked up to the battery. We're also going to wire in each of the four LED strips, so that makes eight power and eight ground wires.
Check out video number 5 of Hoverfly's tutorial video series for a great way to solder a wiring harness (skip to the 5:30 mark for wiring harness).
Make sure you give yourself enough room to make all the necessary connections! Err on the side of too much wire to start with, and trim as needed.
When it's all said and done, you should have just 2 wires with male bullet connectors on them, which will go to the battery. Everything else (other than the servo leads
coming from the ESCs and your receiver) should be soldered/connected.
My approach was to just jump right in and start soldering, but I would've done things differently if I'd seen Hoverfly's video…this step is largely up to you, but try to keep it
neat, and use plenty of heatshrink.
Step 13:
Now it's finally time to install the top frame! Refer to Assembly Diagrams page 7 again, and screw everything into place.
And now you can connect your ESC and Receiver wires to the board! Refer to Hoverfly's SPORT quick start guide (it's not the exact same board, but the installation is
the same for both) to connect the ESCs and your Receiver.
Plug your board into a PC, and download Hoverfly's Setup and Firmware Update Clients. Start reading at page 56 of the User Guide for instructions.
