SP Racing F3 Flight Controller Integrate OSD ACRO Version
The SP Racing F3 Flight Controller Integrate OSD ACRO Version is a professional-grade flight control system designed for FPV racing drones and acrobatic quadcopters, featuring an integrated On-Screen Display (OSD) for real-time telemetry overlay on video feeds. Professional drone racers, FPV pilots, and aerial acrobatics enthusiasts rely on this controller for its precise stabilization, low-latency response, and advanced flight modes that enable extreme maneuvers and competitive racing performance. This flight controller solves the critical challenge of maintaining stable, responsive control in high-speed racing scenarios while simultaneously providing crucial flight data visualization without requiring separate OSD modules.
Product Overview
The SP Racing F3 is a 32-bit flight controller built around the STM32F303 processor, delivering exceptional computational power for complex flight algorithms and real-time sensor fusion. The integrated OSD functionality eliminates the need for external video overlay systems, streamlining the electrical architecture and reducing weight while maintaining full telemetry display capabilities including altitude, speed, battery voltage, current draw, and GPS coordinates directly on your FPV goggles. The ACRO version specifically emphasizes acrobatic flight modes with gyroscopic stabilization, allowing pilots to perform inverted flight, flips, rolls, and other extreme maneuvers with precision control and predictable behavior.
This controller features a 6-axis Inertial Measurement Unit (IMU) with gyroscope and accelerometer sensors sampled at ultra-high frequencies, enabling microsecond-level response times critical for racing applications. The integrated barometer provides altitude hold and terrain awareness capabilities, while the magnetometer offers heading lock functionality for stable directional control. With support for multiple receiver protocols including PWM, PPM, and serial-based systems, the SP Racing F3 integrates seamlessly into diverse drone configurations. The ACRO firmware variant prioritizes manual control responsiveness and aerobatic stability over autonomous flight modes, making it the preferred choice for competitive FPV racing where pilot skill and machine responsiveness determine victory.

How to Use
Installation begins with securing the SP Racing F3 controller to your drone frame using vibration-dampening foam or rubber standoffs to minimize sensor noise from motor vibrations. Connect your ESC signal cables to the designated motor output pins, ensuring correct motor rotation sequence through the configuration software. Wire your receiver to the appropriate input pins matching your selected protocol (PWM, PPM, or serial), and connect the battery through a power distribution board to the 5V regulated input with proper polarity protection. The OSD video input connects directly to your FPV camera, while the video output feeds to your video transmitter, allowing real-time telemetry overlay on your goggles display.
Configuration is performed using the Cleanflight or Betaflight configurator software connected via USB. Calibrate your accelerometer and compass in a magnetically clean environment, then adjust PID tuning parameters to match your specific airframe weight, motor characteristics, and desired flight feel. Test ACRO mode in a safe outdoor space, starting with gentle control inputs to verify gyroscopic response, then progressively increase maneuver intensity. Monitor telemetry data through the OSD during test flights to verify battery voltage, current draw, and temperature readings, adjusting throttle curves and failsafe parameters as needed for safe autonomous recovery. Always perform a range check with your receiver before flying beyond visual line of sight.
Frequently Asked Questions
What is the difference between ACRO mode and Stabilize mode on the SP Racing F3?
ACRO mode provides rate-based gyroscopic stabilization where the controller responds to your stick inputs by rotating the drone at a commanded angular velocity, allowing inverted flight and continuous rolls without self-leveling. Stabilize mode uses angle-based control where the controller automatically levels the drone and limits maximum tilt angles, providing inherent stability but preventing inverted maneuvers. The SP Racing F3 ACRO version prioritizes ACRO mode responsiveness, though Stabilize mode remains available through firmware configuration for beginners or autonomous flight scenarios.
Can I use the SP Racing F3 with my existing FPV camera and video transmitter?
Yes, the integrated OSD accepts standard composite video input from your FPV camera and outputs overlaid video to your transmitter. Simply connect the camera video output to the OSD input pins and route the OSD output to your video transmitter input. The OSD operates independently of flight control functions, so your camera and transmitter require no modification. Ensure your power supply provides adequate current for the camera, transmitter, and controller combined, typically 2-3 amps at 12V for a complete FPV system.
What receiver types are compatible with the SP Racing F3?
The SP Racing F3 supports PWM (individual wire per channel), PPM (pulse position modulation on single wire), SBUS (Futaba serial protocol), and Spektrum DSM2/DSMX receivers. PWM requires one pin per channel, while PPM and SBUS use single input pins, freeing up additional I/O for other functions. Select your receiver protocol in the Cleanflight/Betaflight configurator, then wire accordingly. SBUS and Spektrum receivers require proper signal inversion configuration in software to function correctly.
How do I calibrate the OSD to display correctly on my FPV goggles?
OSD calibration involves adjusting video signal levels and character positioning through the Cleanflight configurator. Connect your FPV goggles to the OSD video output and access the OSD tab in software. Use the character position adjustment tools to center telemetry elements on your screen, then adjust brightness and contrast for optimal visibility in varying lighting conditions. Most pilots prefer positioning altitude and battery voltage in opposite screen corners for quick reference during flight without obstructing forward vision.
