FC/ESC Stacks for FPV and Racing Drones: A Comprehensive Guide

FC/ESC Stacks for FPV and Racing Drones: A Comprehensive Guide

For FPV and racing drone enthusiasts, choosing the right FC/ESC stack is crucial to achieving the best performance possible. FC (flight controller) and ESC (electronic speed controller) stacks are essentially the “brains” of a drone, responsible for controlling its movement and speed. In this guide, we will explore the different types of FC/ESC stacks available, and how to choose the right one for your drone.

Types of FC/ESC Stacks:

  1. Integrated FC/ESC Stack: An integrated stack has the FC and ESC combined into a single board. These stacks are compact and easy to install, making them a popular choice for beginners. However, they are not very customizable, and if one component fails, the entire stack needs to be replaced.
  2. Separate FC and ESC Stack: As the name suggests, a separate FC and ESC stack consists of two separate boards that are connected by wires. This type of stack allows for greater customization and repairability, as individual components can be replaced if they fail. However, they are larger and more complex to install than integrated stacks.
  3. All-in-One (AIO) FC/ESC Stack: AIO stacks are a hybrid between integrated and separate stacks, with the FC and ESC combined into a single board, but still allowing for customization and repairability. These stacks are a good compromise between the two other types.

How to Choose the Right FC/ESC Stack:

  1. Power Output: The power output of a stack determines how much current can be delivered to the motors. It’s important to choose a stack with enough power to meet your drone’s needs. Generally, a 4-in-1 ESC will have more power than individual ESCs.
  2. Size: The size of a stack is important to consider, as it needs to fit within your drone’s frame. Integrated stacks are usually smaller and more compact, while separate stacks can be larger and more difficult to fit.
  3. Features: Different stacks come with different features, such as built-in OSD (on-screen display) or Bluetooth connectivity. Consider what features are important to you and choose a stack that meets those needs.
  4. Budget: FC/ESC stacks can range in price from around $50 to several hundred dollars. Determine your budget and choose a stack that offers the features you need within your price range.


Choosing the right FC/ESC stack for your FPV or racing drone is an important decision that will impact your drone’s performance. Consider the type of stack that best fits your needs, as well as factors such as power output, size, features, and budget. With the right FC/ESC stack, you can achieve the perfect balance between performance and customization for your drone.
