I figured out how to connect the ESC to the PDB with connectors on opposite sides.

If you don't remember my last blog post or YouTube video, you can check the last post. However, to summarize, I discovered that it would be extremely difficult to connect the ESC to the battery connector on the PDB so I had to devise a solution. What I ended up doing was super hacky. I took some cables and simply wired it to the other side. Since I also did this over a week ago, I don't actually remember nor have the patience to find photos in a huge photo library. The video link is below though.

Fun fact: this is the first video that I ever recorded at night, while all the ones before this were actually recorded in the afternoon. At first, I wanted to quickly remove the plastic on the top of the ESC. However, it has labeled for me which cables need to be wired to which motors, so I left it on just in case I forgot or misplaced my printed diagram.

In addition, all the ends of the cables had solder already on them as they were 'pre-soldered,' so what I did was stripped off the ends so I could tie cables together as I pleased and therefore connected it, adding shrink wrap and solder as I went. As you can see in the photo below, it is a photo of me soldering a tiny cable to the connector in order to give the cable slightly more slack.

My reasoning for this was that it would make it easier to solder the ESC cable to the connector. While this logic itself isn't flawed, I did use copper cables so they ended up extremely hard to bend. This made it such that the contact point actually ended up farther away than originally, causing problems, as you can see in the photo below. Although that is not the same photo and I will describe what happened underneath the photo, the cables didn't want to bend so it became too hard to solder underneath the quadcopter.

The cable that is already connected to the ESC was approximately between 18 and 20 gauge wire, as I mentioned in the video. In addition, the data cables connected to the ESC had pins, but I did not use the pins and instead opted to strip the cables out of the pins so I could manually solder them to the flight controller later.

The two cables soldered to the XT60 connector.

What I eventually did was take longer cables and solder them onto the XT60 connector, then wrapped the cables around the back of the quadcopter in order to solder the ESC to the connector on the side of the ESC.
