The Tank of FPV Frames.
The Apex HD series is engineered for pilots who refuse to compromise on durability. Whether you are flying heavy freestyle bando spots with the 5-inch or mountain surfing with the 9-inch, this frame is built to survive. Featuring a legendary “Compressed X” geometry and ultra-thick carbon fiber, the Apex HD offers a locked-in flight feel with industry-leading crash resistance.
Built for Digital HD
The “HD” designation means this frame is optimized for modern video systems. It easily accommodates the DJI Air Unit, Caddx Vista, and O3 Air Unit, providing a protected, isolated space for your expensive electronics.
Why Choose the Apex HD?
-
5.5mm Thick Arms: Across all sizes, the arms are cut from premium 5.5mm carbon fiber. This eliminates arm flex and resonance, resulting in smoother video and fewer broken parts.
-
Sloped Standoff Geometry: The unique frame design uses 28mm front standoffs and 20mm rear standoffs, creating an aerodynamic profile that protects the camera cage while keeping the center of gravity low.
-
Universal Mounting: Features both 20x20mm and 30.5×30.5mm mounting holes for Flight Controllers and VTXs, ensuring compatibility with almost every stack on the market.
Choose Your Size:
-
5-Inch (225mm): The standard for Freestyle and Racing. Agile, responsive, and virtually indestructible.
-
7-Inch (295mm): The Long-Range classic. Perfect for carrying larger batteries and GoPros over long distances.
-
8-Inch (362mm) & 9-Inch (407mm): “Macro Quad” sizes. Designed for heavy-lift cinema rigs or extreme endurance cruising with larger propellers.
