The RaceTek SP Racing F3 Flight Control Board can be used on both multirotor and fixed-wing aircraft, it supports a variety for shapes and motor counts, and is not limited to quadcopters, hexacopters, octocopters, tricopters or planes. Features Cleanflight Open-Source flight controller software which is a 32-bit version of the original 8-bit MultiWii code.

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!

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.

OneShot ESC
Full support for OneShot ESCs for easy PID tuning and a sharper response.

Broad RC receiver Support
Supports SBus, SumH, SumD, Spektrum1024/2048, XBus, PPM, PWM receivers. No external inverters required (built-in).

Programmable LED
Dedicated output for programmable LEDs - great for orientation, racing and night flying.

Battery Monitoring
Battery monitoring ports for voltage and current.

Sonar support for precision low-altitude hold.

I2C Port

I2C port always powered, perfect for external sensors or always-on OLED Screen.

Buzzer port for audible warnings and notification

  • Better coding practices and introducing tests, easier to maintain and for future development
  • Many bugs fixed from Baseflight
  • Supports more flight controllers, including CC3D, CJMCU and Sparky
  • Supports OneShot ESC and more than 8 RC channels
  • Additional PID controllers that use floating point arithmetic operations (now has 3 built-in PID Controllers)
  • Many more features such as RGB LED strip support, Autotune, In-flight PID tuning with your radio, blackbox flight data logging etc.
  • The hardware was designed by the lead developer of Cleanflight to be more capable than the previous-generation STM32F1-based boards after hearing feedback from the Cleanflight users, contributors and top-pilots.

RaceTek SP Racing F3 Flight Control Board
This board is a clone that has a design problem with the buzzer that causes it to be on all the time... The buzzer's negative terminal in the connector is wired to battery ground (which causes it to buzz constantly). To this board's buzzer work, you'll have to solder to the pads on the other side of the board where the negative pad connects to the transistor to turn on an off the buzzer. Or, get a non-clone.)
