5 Best Flight Controllers for Drones

As you consider the best flight controller for your drone, you want to ensure that you choose wisely. If you get the wrong controller, your drone may fly sluggishly or be very unpredictable. The intended use of the controller is essential, too. You need to look for different models when you want to learn to fly or when you need a controller for professional purposes.

Hello everyone! My name is Lavelle and I am a licensed drone pilot and a long-time drone enthusiast. For the past ten years, I have been flying my drones across the United States and abroad for both commercial and recreational purposes. During this time, I have come across some excellent flight controllers that are used with DIY drones. 

In this article, I will cover some of the main things you should look for in flight controllers and I will share with you my list of the best flight controllers for drones. I will also go over a couple of frequently asked questions.

Key Takeaways

  • There are four main processors of controllers to choose from. They include the F1, F3, F4 and F7 models. 
  • Look for controllers that offer good firmware support options. This is critical to modify your design when needed with little trouble.
  • Consider controllers that give you a wifi or Bluetooth option since these are newer elements that allow you to build a more advanced drone.
How do I choose a flight controller?

There are a few things to consider when choosing a flight controller including the correct firmware, the mounting pattern, the sensors, and the best processor. 

There are several good flight controller options in the marketplace for quadcopters. I recommend you look for one with three layers and a good video transmitter.

What Makes The Best Flight Controller for Drones

Here are some things you should take into consideration before making a purchase.

Firmware Support

Some flight controllers come pre-configured, while others don’t. When building a drone, there is a good chance that you will want to make some modifications, therefore, having access to open-source firmware is important. One example of open-source firmware is Betaflight, which allows you to configure the flight controller easily and quickly.

Mounting Pattern

There are different mounting patterns on circuit boards. It is important to look for the mounting pattern that matches the circuit board you are using to build your drone and to mount your controller on. You want to ensure that you use a DIY kit with specifications that are well spelled out to get the right mounting pattern for your controller.


The processor is a vital component that houses the incoming and outgoing data for your drone. It calculates information and determines the tasks that are to be completed within your drone’s circuitry. There are four types of processes: F1, F3, F4, and F7.


Most standard controllers use two types of sensors: the gyroscope and the accelerometer. The accelerometer measures the speed of the drone when it’s moving linearly. The gyroscope sensor measures the tilt and lateral orientation of the drone. Both are necessary components of the flight controller.


It is important to know what you are using the drone for and that should determine the kind of price range you are willing to explore for your controller.

  • Processor: STM32F722

If you’re looking for a versatile controller with many options, the SpeedyBee V3 F7 is your best choice. This is an excellent option that offers a much faster data transfer speed and can update firmware versions in less than one minute.

The remarkable features of this controller include two installation ports for the video transmitter, additional ports for the receiver, camera, GPS, and VTX, and a TVS protective diode. You can get the Blackbox data in less than one minute and it can support up to a whopping 8 motors.

The numerous installation ports on this model are what make it unique. These options enable you to create a premium, competitive drone.

The main reason why it slipped to number two on my list is that the circuit board is prone to giving out low resonance which produces lower-than-optimal performance metrics.

My Verdict: This could easily be the number one choice on my list if the manufacturer can figure out why the resonance issues persist. Otherwise, this is a great option and provides exceptional value for the user.

3. iFlight SucceX Micro F4 V2.1 (Best Micro)

  • Mounting Size: 16x16mm
  • Firmware: Betaflight
  • Installation Size: 21x21mm
  • Controller Type: F4 V. 2.1
  • Processor: Gyro MPU6000

The number three position on my list is the iFlight SucceX Micro F4 controller. It is designed well and is primarily used for micro racing drones. In contrast to the typical normal flat layout design, it has a tower layout system. It is very lightweight and is perfect for building a good racing drone.

The electronic speed control and the video transmitter are stacked on top of each, thus giving you the tower design. It also has pinned interconnects that make the assembly process smooth and painless. 

I like the stacked tower layout design of this controller. This design gives you the ability to add layers without necessarily adding too much weight that would slow the drone down.

The one thing that gives me cause for concern is that this controller is designed for advanced-level users. Users with little or no experience in building drones will not find it to be easy to configure this controller. The cost is also more than its competitors.

My Verdict: If you are an advanced drone builder with some good technical skills and you want a great controller, this is your best option. It is well-designed with the pros in mind. The onboard memory chip is also a nice addition.
