Mark4 7 Inch8 Inch Racing FPV Frame Kit Crossing Aircraft Traversal Frame FPV Drone

Product Description
The DONGJI TYI Mark4 7-Inch / 8-Inch Carbon Fiber FPV Drone Frame redefines durability and payload capacity in long-range FPV technology. Featuring a highly optimized 3K carbon fiber construction, it is remarkably stiffer and more resilient than conventional legacy frames. This significant enhancement in structural integrity, combined with a spacious classic H-frame geometry, makes the Mark4 an incredibly robust and flexible solution for a wide range of long-range cinematic and heavy-lift flight applications.

Key Features
● Innovative Design & Advanced Components
Optimized Configuration: Features the most advanced 3K full carbon fiber plates and CNC-machined aviation-grade hardware, ensuring high structural integrity and exceptional flight performance under extreme loads.
Original Frame Design: A pioneering rigid H-frame structure maintains reliability during high-speed, long-distance flights, ensuring minimal resonance and the elimination of "jello" effects even in harsh wind conditions.
Deep Customization: Incorporates versatile mounting patterns (30.5x30.5mm and 20x20mm) tailored for large-scale flight controllers and high-amperage ESCs, ensuring long-term stability and strong reliability.
● Intelligent Vibration & Cooling System
Self-Developed Anti-Vibration Technology: An intelligent shock-absorption design keeps the flight stack performing at its best, significantly reducing gyro noise for buttery-smooth HD video.
Aerodynamic & Spacious Core Design: The center frame's spacious and aerodynamic layout allows for rapid heat dissipation from high-power Digital HD VTX units, preventing overheating during extended long-range operations.
Integrated Payload System: A unified center-core design integrates secure mounting for both heavy cinematic payloads and massive Li-Ion/LiPo battery packs, reducing center-of-gravity shifts while optimizing flight regulation.
● Robust & Heavy-Duty Arm Structure
Heavy-Duty Build: The frame features ultra-thick carbon fiber arms engineered specifically for 7-inch and 8-inch macro builds, utilizing highly durable materials to withstand immense thrust and prevent snapping during hard landings.
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, heavy-gauge 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), catering to advanced builders requiring crystal-clear, long-range 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, heavy antennas, and action camera mounts.
Non-Damage Wiring Protection: Features CNC-chamfered carbon edges that ensure delicate heavy-gauge motor wires are protected from chafing, increasing frame and electronic lifespan significantly in a single build.
Advanced Heavy Payload Capability: Unique frame proportions and high-strength hardware allow for the efficient carrying of extremely demanding payloads, boosting overall lifting efficiency and long-range flight times significantly.
● 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 heavy-duty components efficiently.
Flexible Build Adjustments: Users can fine-tune their center of gravity, standoff heights, and camera angles for specific, unique macro-cinematic requirements.
