5 Inch 225mm 2256inch 260mm295mm Carbon Fiber Quadcopter Frame Kit 5.5mm Arm for APEX FPV Freestyle RC Racing Drone Models

Product Description
The DONGJI 5/6/7-Inch Carbon Fiber FPV Freestyle Frame Kit redefines durability and versatility in multi-rotor technology. Featuring a highly optimized multi-size platform, it is remarkably stiffer and more resilient than conventional legacy frames. This significant enhancement in structural integrity, combined with multiple wheelbase options—5-inch (225mm), 6-inch (260mm), and 7-inch (295mm)—makes this frame an incredibly portable and flexible solution for a wide range of aggressive freestyle, cinematic, and long-range flight applications.

Key Features
● Innovative Design & Advanced Components
Optimized Configuration: Features the most advanced 3K full carbon fiber plates and aviation-grade hardware, ensuring high structural rigidity and exceptional flight performance across all size configurations.
Original Anti-Vibration Design: A pioneering rigid frame structure maintains reliability during high-speed, high-impact freestyle maneuvers, ensuring minimal resonance and the elimination of "jello" effects.
Deep Customization: Incorporates versatile mounting patterns (30.5x30.5mm and 20x20mm) tailored for broad flight controller and ESC compatibility, ensuring long-term stability and strong reliability.
● Intelligent Structural & Cooling System
Self-Developed Airflow Technology: An intelligent, aerodynamic center frame design keeps the electronics stack performing at its best in harsh, high-throttle flight environments.
Thermodynamic Core Design: The center bay's spacious layout allows for rapid heat dissipation from high-power Video Transmitters (VTX), preventing overheating during extended flight sessions.
Integrated Core System: A unified center-core design integrates secure mounting for both the flight stack and top-mounted batteries, reducing center-of-gravity shifts while optimizing flight regulation.
● Robust & Heavy-Duty Arm Structure
Ultra-Thick 5mm Build: The frame features ultra-thick 5mm carbon fiber arms across all sizes, utilizing highly durable materials to withstand immense thrust and prevent snapping during hard landings or "bando" crashes.
Modular Interface: Easily interchangeable individual arms adapt to rigorous flying environments, allowing for quick field repairs without disassembling the entire center core.
● Versatile & Builder-Friendly Interface
Spacious Build Area: A highly optimized top and bottom plate layout offers an intuitive building experience, enabling effortless electronic component installation and wire routing for bulky components.
Multiple Video System Modes: Includes seamless support for traditional Analog setups as well as modern Digital HD systems (such as the DJI O3 Air Unit, Caddx Vista, or Walksnail), catering to advanced builders requiring crystal-clear video transmission.
● Smart Features for Efficiency and Convenience
Pre-set TPU Mount Compatibility: Supports a comprehensive library of highly customizable 3D-printed TPU mounts, enabling quick access and flexible installation for GPS modules, antennas, and action camera mounts.
Non-Damage Wiring Protection: Features CNC-chamfered carbon edges that ensure delicate motor wires are protected from chafing, increasing frame and electronic lifespan significantly in a single build.
Advanced Multi-Discipline Capability: Unique frame proportions allow the 5-inch to excel at sharp freestyle, while the 6-inch and 7-inch variations boost overall lifting efficiency and stability for mid-to-long-range cruising.
● After-Sales Support & Customization
Builder's Interface: Provides open access for professional FPV pilots and engineers to configure electronics, perform field repairs, and swap out components efficiently.
Flexible Build Adjustments: Users can fine-tune their center of gravity, standoff heights, and camera angles for specific, unique freestyle and cinematic requirements.
