7 Best Drone Flight Controller of 2020

7 Best Drone Flight Controller of 2020

With each new build, drone enthusiasts who are actively involved in the process of assembling these autonomous flying vehicles dream of going faster and higher. There is a massive difference between people who use drones for professional purposes and those who build them as a hobby. This post is about flight controllers, one of the primary components of a DIY quadcopter.

A flight controller is the brain of a drone. It makes all the decisions–with or without receiving signals from the remote controller. When you assign a particular task to your drone, the flight controller processes the incoming signal and sends the relevant signals to the motors and other parts of the drone. This post is intended to help you find the best flight controller for your drone kit.

What is the Best Flight Controller for a Quadcopter?

If the price is not a concern and you are looking for the best product in the market, I would reckon iFlight SucceX Micro F4 V2.1 to be the best flight controller for a quadcopter. Indeed there are other budget-priced products available in the market–with similar features– but they all have something missing. No product except iFlight SucceX Micro F4 V2.1 is perfect.

For instance, HGLRC FD413 F4 Flight Controller Stack does come with a similar flight tower system, but it has two layers as opposed to three. The video transmitter (VTX) is missing. The FD413 F4 is suitable for those who do not wish to stream live video on a monitor. Since we are talking about the top product in the market, I would pick Micro F4 V2.1 over FD413 F4.

How Do I Choose a Drone Flight Controller?

Contrary to what most people think, building a drone at home does not require a college degree in electronics engineering. Also, you don’t necessarily need in-depth knowledge of autonomous flying machines. That being said, you do need some Googling skills and curiosity to learn something new.  

Google can answer most of your queries, whereas YouTube video tutorials can guide you through the installation process. Trying to build a drone merely by reading the instruction manual can be quite challenging. Before you move ahead with the installation process, you must have the right components and parts at your disposal. This section will help you choose a drone flight controller.

Here are the Factors You Should Consider Before Choosing a Drone Flight Controller

1) Open-Source Firmware Support

A flight controller may or may not be available pre-configured. Also, since you are building a DIY quadcopter, you will most likely need to make some modifications. An open-source firmware like Betaflight allows you to configure the flight controller within seconds. You don’t need to be an expert. Hence, look for open-source firmware support before choosing a flight controller.

2) Mounting Pattern

Flight controllers are just circuit boards that need to be mounted on a plane surface. Before ordering a flight controller, it is essential to check the drone kit specifications once. Order the one that will fit on your drone kit perfectly.

3) Price

The price is, by far, the most critical factor. Before choosing a flight controller, always make sure why you are building the quadcopter. Are you planning to use the drone for aerial photography? Or are you into drone racing? The more critical the application, the more money you should be willing to spend.

4) Processor

The processor is the critical component where all the incoming and outgoing information is processed. It performs calculations and carries out tasks it is programmed to function. If you head out to buy a flight controller, you will find them with four types of processors: F1, F3, F4, and F7. F4 and F7 are the latest ones. 

5) Essential Sensors

Gyroscope and accelerometer are two standard sensors used in a flight controller. Without these two, controlling your quadcopter will become a nightmare. An accelerometer can measure the speed of an object (in this case, the quadcopter) when it is moving linearly. On the other hand, the Gyroscope sensor can also measure the tilt and lateral orientation. Both sensors are necessary components of a flight controller. 

Conclusion

Choosing an incorrect flight controller for your drone can make your drone sluggish, erratic, or utterly unpredictable. This is because a flight controller (or drone in general) should be chosen keeping the application in mind. It matters if you are merely trying to learn the flight characteristics or want to use this device for professional purposes.
