I build A LOT of FPV Race dones. At one point I was building 2-3 per week though I've really been trying to pump the breaks on that. Ocassionally I turn on the GoPro and record some of those builds and then tediously cut them into something worth watching. In doing so I try and crop out most of the lulls and speed up parts that are repetitive. I also try and do voice over commentary on what I'm doing. When you do as many builds as I have you start to pick up tips and tricks to building that make things a lot easier. I try and call those things out as I go. Tips like "Don't tin wires over your components". Here are some of those videos from my YouTube channel.
