Selecting the ideal flight controller for your FPV quadcopter can be a challenging task given the plethora of options available. Each controller offers unique features, and technological advancements have led to more powerful micro-controllers for enhanced optimization. This guide aims to simplify the process of choosing a flight controller tailored to your needs. Additionally, we'll highlight noteworthy offerings from MEPSKING, such as the MEPS F7 and MEPS 2306, which can benefit your FPV drone endeavors. Let's delve into the ESC landscape.

  1. What are the Quadcopter Flight Controllers?

Physically, a flight controller is a circuit board with electronic chips—a counterpart to a laptop's motherboard and processor. It serves as the drone's brain, housing intelligent electronics and software that monitor and control all drone operations. Flight controllers vary in size and complexity, much like the brains of different organisms.

  1. Flight Controller Processors

F1, F3, F4, and F7 are commonly used processors in mini quads. Advancements led to higher processing speeds, with F7 being the latest and fastest, capable of executing 216 million cycles per second. This increased speed enhances the controller's ability to execute commands swiftly.

Processor

Operating Frequency 

F1 72 (MHz)
F3 72 (MHz)
F4 168 (MHz)
F7 216 (MHz)
  1. Firmware

Various firmware options like Betaflight, Cleanflight, Raceflight, and KISS cater to specific functions. Betaflight, being open-source, boasts a large user base and a wide range of flight controllers. KISS, a closed-source firmware, limits users to proprietary flight controllers. iNav is suitable for those interested in automated flying and GPS waypoint missions.
