As an electronic engineer and FPV drone pilot, making my own flight controller has been a project around for a while. I finally get it done, so let's dive into the design process of a Betaflight based flight controller.
When it comes to building a durable quad, people often think of making a stronger frame or adding motor guard. But other parts such as the stack are left as is. This project focus on the protection of those electronic parts.
In early 2018, Runcam extended their Split camera lineup with the Split Mini, bringing HD capabilities to smaller quad. Back then, I was preparing a backpacking trip, and I really wanted to take a drone with me. Because space and weight has to be optimized for this kind of trip, a full size 5" quad was not an option. So I started looking how to combine this Spit mini camera with the 2.5" quad hype going on at this time.
