The Mountain Surfer’s Choice.
The Mark4 7-Inch Combo is a complete power system and frame kit designed for pilots looking to step into long-range FPV. By combining the proven geometry of the Mark4 frame with efficient low-KV motors and a robust electronics stack, this kit provides everything you need to build a stable, long-endurance quadcopter.
Why choose this combo?
-
Proven Geometry: The Mark4 295mm frame is an industry standard for a reason. Its H-shape design (Squashed X) offers plenty of room for electronics while keeping the props out of view. With 5mm thick arms, it is rigid enough to handle the torque of 7-inch props without vibration.
-
Efficient Propulsion: The included 2807 / 2806.5 1300KV motors are the “sweet spot” for 6S long-range cruising. They provide enough torque to carry a GoPro while maintaining high efficiency for longer flight times.
-
Reliable Power Stack: The F405 Flight Controller paired with a 60A 4-in-1 ESC ensures smooth power delivery. The ESC features an EMI shielding shell and onboard capacitors to filter noise, giving you cleaner video and safer flights.
Key Features:
-
Long Range Ready: optimized for 6S LiPo or Li-Ion batteries.
-
Durable Build: Full 3K Carbon Fiber with 5mm arms and reinforced plates.
-
Smooth Video: Stable frame resonance and filtered power reduce “jello” in your HD footage.
-
Complete Power Train: No need to guess which motors fit the ESC; we’ve matched them for you.
