How many types of aircraft flight control firmware are there?
In recent years, with the popularity of FPV drones, there are more and more choices of flight controller firmware. Different flight control firmware has its own characteristics in terms of functions, performance and applicable scenarios. This article will sort out the current mainstream types of aircraft flight control firmware and compare their characteristics through structured data to help pilots choose the solution that best suits them.
1. Overview of mainstream flying control firmware

At present, the common flight control firmware in the field of flying vehicles mainly includes the following types:
| Firmware name | Developer | Main features | Applicable scenarios |
|---|---|---|---|
| Betaflight | Community open source | High performance, low latency, supports multiple PID parameters adjustment | Racing, flying flowers |
| INAV | Community open source | Support GPS navigation and automatic return | Long endurance, aerial photography |
| KISS | Flyduino | Closed source, smooth flight experience | Professional pilot |
| Emuflight | Community open source | Optimized smoothness, suitable for fancy flying | Flower fly, free flight |
| ArduPilot | Community open source | Supports multi-rotor and fixed wing, with comprehensive functions | Professional aerial photography, surveying and mapping |
2. Detailed comparison of each flight control firmware
To more intuitively understand the differences between different firmwares, here is how they compare on key features:
| Firmware name | Open source/closed source | PID parameter adjustment complexity | GPS support | Suitable for pilot level |
|---|---|---|---|---|
| Betaflight | Open source | high | Limited support | Intermediate or above |
| INAV | Open source | in | Full support | Beginner to Advanced |
| KISS | Closed source | low | Not supported | Advanced |
| Emuflight | Open source | in | Not supported | Intermediate or above |
| ArduPilot | Open source | high | Full support | Professional grade |
3. How to choose the flight control firmware that suits you?
When choosing flight control firmware, you need to consider the following points:
1. Purpose of flight:If it is racing or fancy flying, Betaflight or Emuflight is more suitable; if automatic return or long endurance function is required, INAV or ArduPilot is a better choice.
2. Technical level:Beginners can start with INAV because of its relatively simple parameter settings, while advanced users may prefer the high performance of Betaflight or KISS.
3. Hardware compatibility:Some firmwares have specific hardware requirements, for example KISS requires dedicated flight controls, while Betaflight and INAV support a wider range of hardware.
4. Future development trends
With the advancement of flying machine technology, the flight control firmware is also constantly updated. In the future, more intelligent algorithms may appear, such as AI-based automatic parameter adjustment functions and more powerful navigation capabilities. At the same time, the power of the open source community will continue to promote the diversification and optimization of firmware.
In summary, there are many types of flight control firmware for flying machines, and each firmware has its own unique advantages. Pilots can choose the most suitable solution based on their needs and skill level to get the best flying experience.
