Mark4 7-Inch Long Range FPV Frame Kit – 295mm Carbon Fiber (5mm Arms)

The Foundation for Long Range FPV.
The Mark4 7-Inch is the industry-standard frame for pilots looking to build a reliable long-range cruiser or “mountain surfer.” Featuring a stretched 295mm geometry, this frame is designed to carry larger batteries and cameras while maintaining a stable, locked-in feel.

Rigid & Vibration Free
When flying 7-inch propellers, frame rigidity is critical to preventing “jello” in your video. The Mark4 features 5mm thick carbon fiber arms and a reinforced center structure. This ensures that the low-frequency vibrations common in large drones are dampened effectively.

Optimized for Big Power
While compact frames use small motors, the Mark4 7-Inch is engineered to fit 2806.5 and 2807 motors. This allows you to swing 7-inch props with authority, giving you the efficiency needed for 15+ minute flight times (with the right battery).

Key Features:

• H-Shape Geometry: Provides ample deck space for GPS units, large VTXs, and bigger LiPo/Li-Ion batteries.

• Full Carbon Construction: High-quality 3K carbon fiber with chamfered edges.

• Camera Protection: The side plates extend beyond the camera lens to protect it during rough landings.

• Universal Mounting: Fits standard 30.5×30.5mm stacks and 19mm micro cameras.
