Mark4 HD Carbon Fiber FPV Frame Kit – 5-Inch Freestyle & 7-Inch Long Range

The Classic Freestyle Workhorse, Now HD Ready.
The Mark4 HD is one of the most popular frame geometries in FPV, known for its distinct low center of gravity and super-durable design. Updated to accommodate modern digital FPV systems, this frame features a roomy fuselage designed specifically to fit the DJI Air Unit, Caddx Vista, or standard Analog setups.

Two Sizes, One Proven Design:

• Mark4 HD5 (5-Inch): The standard for freestyle flying. With a 224mm wheelbase, it offers agile, locked-in handling perfect for bando bashing and cinematic tricks.

• Mark4 HD7 (7-Inch): Built for long-range exploration. The stretched 295mm geometry supports larger props and batteries, giving you the efficiency needed for mountain surfing and long-distance cruising.

Key Features:

• High-Quality Carbon: Features full 3K woven carbon fiber with chamfered edges for a smooth finish.

• Durable Arms: Both versions utilize 5mm thick arms, ensuring high crash resistance and minimal vibration for jello-free footage.

• HD Integration: The frame layout is optimized for the DJI FPV Air Unit, providing ample airflow for cooling and secure mounting.

• H-Shape Geometry: Provides a spacious deck for building while keeping the props out of view in most HD recording angles.
