Operational: June 2023 –

This drone is named for baboons that one finds in South Africa, often chilling, and often speeding into action!

Below are the components I have on this quad. After an incident where my drone took a 200m tumble I replaced the faulty ESC and at the same time replaced the motors and flight controller. It is a nod to the Armattan frame that I could do this and not write-off the drone completely. The original components and build can be found in my How to build a 5″ HD freestyle quad with MEPS components post.
