The Seriously Pro Racing F3 Flight Controller (SPRacingF3) has been designed to deliver incredible flight performance based on proven and tested sensors while additionally providing unparalleled and I/O capabilities in a small and extremely lightweight form-factor using a next-generation CPU. The SP3 Controller is favoured amongst some of the top pilots for its performance, reliability and black box recordings.
The SP Racing F3 gives you all the features you need for the heart of your aircraft, whether you're into FPV racing, acrobatic flying or aerial photograp. It supports a variety of aircraft, tricopters, quadcopters, hexacopters, octocopters, planes and more.
The SP Racing F3 runs the open-source Cleanflight flight control (FC) software which has an ever-growing community of friendly developers and users.
- Flight Performance: The SPRacingF3 builds on tried and tested software, processor and sensor technology to make your aircraft fly like it's on rails.
- No-Compromise I/O: Use all the features all the time; e.g. Connect your OSD + SmartPort + SBus + GPS + LED Strip + Battery Monitoring + Sonar + 8 motors - all at the same time!
- Configurable: The SPRacingF3 runs Cleanflight which can be configured to suit your needs using a cross-platform GUI (Windows/OSX/Linux).
- Tiny and lightweight: The SPRacingF3 has a standard 36x36mm form-factor with 30.5mm mounting holes and weighs just 6 grams.
- Flight Logging: On-board high-capacity black box flight log recorder - optimize your tuning and see the results of your setup without guesswork.
- Next-Generation CPU: The SPRacingF3 has an ARM Cortex-M4 72Mhz CPU with Math co-processor (FPU) for efficient flight calculations that gets more done in less time. Loop times up to ~2x as fast as previous-generation STM32F1 based boards.
- Developer Friendly: Developer friendly debugging port (SWD) and boot mode selection, unbrickable bootloader.

What do I need to know about flight controllers? You should think of the flight controller (FC) as the brain of your multi rotor UAV. Its principal roll is to stabilised your craft, some more sophisticated flight controllers can also fly your drone autonomously. In order to keep the drone perfectly balanced the FC takes continuous measurements from the Inertial Measurement Unit (IMU). These are electronic sensor devices such as a gyro, accelerometer, compass or GPS that measures the velocity, orientation and gravitational forces of the multi rotor. Based on their signals and command inputs from the pilot, the FC processes the data using complex algorithms and makes adjustments to the speed of each rotor to keep the craft level. A multi rotor has four controllable degrees of freedom: Yaw, Roll, Pitch, and Altitude. Each degree of freedom can be controlled by adjusting the thrusts of each rotor. When it comes to selecting a FC, there is a lot of choice. Some of the notable ones are the KK, MultiWii, Ardupilot, Naza, Rabbit and WKM. Your choice of FC is mainly dependent on what you want and your budget. Advanced FCs generally have more features and sophisticated sensors like gyro, accelerometer, sonar, GPS, Magnetometer. Some flight controllers include the IMU and some don’t. Different FC will have different flying capabilities. The following list states the main ones.
- Gyro Stabilization - the ability to easily keep the multi rotor stable and level under the pilot’s control. This is a standard feature of all flight control boards.
- Self Leveling - the ability to let go of the pitch and roll stick on the transmitter and have the copter stay level.
- Care Free - The pilot can control the drone as if it is pointing in its original direction as the orientation of the copter changes.
- Altitude Hold - the ability to hover a certain distance from the ground without having to manually adjust the throttle.
- Position Hold - the ability to hover at a specific location.
- Return Home - the ability to automatically return to the point where the copter initially took off.
- Waypoint Navigation - the ability to set specific points on a map that copter will follow as part of a flight plan.
You should also consider the quality of the components, software package and importantly extent of support, both official and community based. Then there is the question of compatibility with peripheral accessories. The more advanced systems can communicate with a ground station via a telemetry link, allowing the pilot to program an autonomous flight and track progress remotely. Finally there is cost, prices range from £20 for some of the most basic FCs to over £1000 for the most sophisticated, such as the DJI Wooking.
