It supports a load of flight controllers, and has an impressive list of compability with advanced FPV features like OSD control, VTx control, Blheli Dshot. Betaflight might not be able to fly your drone for you, but it will give you the best feel and peformance for FPV flying!īetaflight was forked from Cleanflight Why should you use it?

Although you could use any of the full autopilot projects to power your FPV quad, betaflight developers are focused on getting the most speed and performance out of your flight controller and quadcopter, with things like reading sensor data at 32Khz and sending updates to the motor at the same insanely fast rate. Primarily used for quadcopters, it also has support for fixed wing FPV planes. BetaFlightīetaFlight is currently the most popular FPV firmware and is considered to be on the cutting edge of FPV flight controllers. These projects are dedicated to FPV and FPV racing, they have modes and features dedicated to squesing the extra performance out of your motors to make your aircraft as agile as possible. The only real downside is the lack of easy to obtain hardware, and the fact you need to be quite technical to work with paparrazi (as it only runs on Linux for now) FPV and Racing Projects One could argue that this has some of the most advanced features out of the box. The paparazzi firmware has been around for a long time (since 2003) and is constantly being improved. However, this firmware is still actively developed and mainly used by universities. Also, alot of the hardware is not widely available, or fully open source which is a shame. It has not received as much adoption as other projects because it is quite technical. Paparazzi was the first truly open source firmware to control drones. If you want to run a powerfull, but cheap autopilot platform (running CC3D boards or similiar), librepilot is a great option for you. Librepilot was forked from OpenPilot Why should you use it? The firmware itself is also solid and great to work with and on, The only downside is that there are not as many features as arudpilot, but this is mainly because this project is not as popular so has fewer developers in the community. The GUI is an excellent piece of software. LibrePilot aims to be a general flight autopilot that supports both fixed and rotor wing aircraft. This is why PX4 is more attractive for business use. So if you plan to develop some special function that you want to keep private or sell, PX4 is the way to go. With ardupilot, any changes need to be shared as open source. This makes PX4 more attractive for commercial use since you dont need to make your modifications open source.

However, the key differentiation is with the software license. I will not discuss that here as these are all a matter of opinion. There are many discussions between PX4 and Ardupilot to compare which one is better. However in terms of core autonomous functions PX4 and Ardupilot are very similar. It is only when you get to very specific functions you may notice some variations betwen the two projects. Similarly, since both systems use the same telemetry protocol (MAVlink) alot of software is also compatible with both such as Qgroundcontol.

On the surface you can consider PX4 flight stack to be similar to ardupilot as there is alot of hardware that can run either PX4 or Ardupilot firmware. The most famous platform that runs the PX4 flight stack is some of the drones from Yuneec. This project supports multiple vehicle types, also has an active developer community. The PX4 flight stack is another powerful, fully featured autopilot. It also has the largest developer community and is used on many commercial systems. If you want to have a fully featured autopilot system with 3D waypoint navigation, and a wide range of hardware and software support ardupilot is the best one out there. The firmware is divided into three branches: Ardupilot for fixed-wing aircraft, Arducopter for multirotors and helicopters, and Ardurover for ground-based vehicles. The software can control just about any vehicle, both fixed-wing planes, quadcopters and everything between including hybrids, ground rovers and boats. It has been around since the beginning and has an active development community. Ardupilot is probably the most popular drone autopilot software.
