performance FPV stack built for reliable control, responsive power, and HD video transmission What this product delivers Advanced flight control with the F7 flight controller for precise tuning, stable flight behavior, and support for complex flight modes and peripherals. Smooth, responsive power management from a 45A ESC that supports efficient current delivery and improved motor responsiveness during aggressive maneuvers. Immersive HD video and lowlatency streaming via the O3 Air Unit for clearer live view and higher quality footage for review or content creation. Available in PNP and BNF configurations to match your build preference and skill level. Choose PNP for integration into custom builds or BNF for a readytofly experience with a compatible receiver bound at delivery. Key benefits and how it solves common problems Faster setup and fewer compatibility headaches: The F7 controller and O3 Air Unit integrate cleanly with standard FPV components, reducing wiring and configuration time so you can fly sooner. Better control and stability: The F7 flight controller provides the processing headroom needed for advanced filtering and features, leading to smoother flight and easier tuning. Reliable thrust and responsiveness: The 45A ESC delivers consistent power to the motors under load, helping prevent motor lag and maintaining control during rapid throttle changes. Improved video clarity and situational awareness: The O3 Air Unit provides HD transmission with low latency, making it easier to track subjects, judge distance, and capture usable footage. Flexibility for different pilots: PNP option lets experienced builders integrate their chosen receiver and radio system. BNF option is suited to pilots who want a packaged solution that binds to a compatible radio. Technical highlights Flight controller: F7 processor architecture for advanced performance and configuration flexibility ESC: 45A unit designed for efficient power delivery and enhanced motor response Video system: O3 Air Unit providing HD video transmission and onboard video capability Form factor: Compact stack layout suitable for common racing and freestyle frames where space is limited Construction: Designed with durable electronic components and standard connector layouts for straightforward installation and serviceability Compatibility: Offered in PNP and BNF; works with standard RC transmitters and common receiver protocols as required by each configuration Practical use scenarios Race preparation: Swap this stack into a lightweight racing frame for improved throttle response and lowlatency video feedback during speed laps and competitions. Content capture: Use the O3 Air Unit to record and stream HD footage while relying on the F7 controller and 45A ESC to maintain stable, controllable flight paths for cinematic shots. Freestyle practice and upgrades: Install the PNP version when upgrading an existing frame to gain finer motor control and cleaner video, or choose BNF to get flying quickly with minimal setup.
