This is kind of a silly build. It definitely doesn't have the power to weight ratio of my modern 5" builds, but it does have the power to haul a session around.

Now we've got the "GoPro Lite". Remove the battery, displays and casing and you're left with a small, lightweight board and sensor. Wrap it in protective TPU casing and you've got a 30g micro GoPro. The Hero6 is..

This guide will walk you through the process of building your first FPV quad.

I chose these parts to minimize the amount of soldering at no cost to the quality. A typical build requires around 30 solders while this only needs 25. It's not a huge difference, but..
