Condition: Brand New
    *Model: Acro
       *Next-generation hardware for your multi-rotor
    *The Seriously Pro Racing F3 Flight Controller (SPRacingF3) was designed to give awesome flight performance based on tried and tested sensors 
      whilst also providing unparalleled and I/O capabilities in a small and extremely lightweight form-factor using a next-generation CPU.
    *Flight Performance: The SPRacingF3 builds on tried and tested software, processor and sensor technology to make your aircraft fly like it's on rails.
    *Configurable. The SPRacingF3 runs Cleanflight which can be configured to suit your needs using a cross-platform GUI (Windows/OSX/Linux).
    *Flight Logging. On-board high-capacity black box flight log recorder - optimize your tuning and see the results of your setup without guesswork.
    *Developer Friendly.Developer friendly debugging port (SWD) and boot mode selection, unbrickable bootloader.
    *Broad RC receiver Support. Supports SBus, SumH, SumD, Spektrum1024/2048, XBus, PPM, PWM receivers. 
      (No external inverters required (built-in).)
    *Battery Monitoring. Battery monitoring ports for voltage and current.
    *I2C Port. I2C port always powered, perfect for external sensors or always-on OLED Screen.
    *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!
    *Tiny and lightweight. The SPRacingF3 has a standard 36x36mm form-factor with 30.5mm mounting holes and weighs just 6 grams.
    *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.
    *OneShot ESC. Full support for OneShot ESCs for easy PID tuning and a sharper response.
    *Programmable LED. Dedicated output for programmable LEDs - great for orientation, racing and night flying.
    *Sonar. Sonar support for precision low-altitude hold.
    *Buzzer port for audible warnings and notifications.
    *The SPRacingF3 gives you all the features you need for the heart of your aircraft, whether you're into FPV racing, acrobatic flying or aerial
      photography it's perfect.
    *Supports a variety of aircraft, tricopters, quadcopters, hexacopters, octocopters, planes and more.
      The SPRacingF3 Design is:
    *Practical - Easy to access connectors and solder pads.
    *Configurable - Choose to use connectors, solder pads or pins.
    *Stackable - Mount to your PDB or OSD.
    *Compact - Only 36x36mm.
