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.
