Selecting Props for Your Multirotor

I have decided to spend the next week or so writing some posts covering basic design decisions for choosing multirotor components. Multirotors have many different parts, each of which is available in a number of different models. Choosing the correct mix of components...
A Flight Controller’s View of the World

A Flight Controller’s View of the World

Flight controllers are the metaphorical brains inside every multirotor aircraft. They handle all of the functions related to keeping the multirotor stably airborne and executing commands from the pilot. Flight controllers have a complicated, multi-faceted job: they...
