Holybro X500 Frame Kit
by Holybro

The Holybro X500 Frame Kit (V2) is a professional-grade, 500mm-class quadcopter chassis engineered as a lightweight, robust, and affordable development platform for autonomous sUAS prototyping, academic robotics research, and aerial surveying. Constructed with full carbon fiber twill plates and high-strength 16mm carbon fiber tube arms, this frame maximizes structural rigidity while maintaining an incredibly light foot-print. This product is the standalone Frame Kit, providing system integrators and custom builders with a clean, high-end physical foundation to curate their own power plants, companion computers, and custom sensor payloads without being constrained by pre-selected electronics.

The X500 V2 introduces numerous mechanical refinements over legacy drone frames. The 16mm carbon fiber tube arms are anchored by newly designed, fiber-reinforced nylon connectors featuring convenient alignment notches on both the motor and body sides, resulting in a much easier and perfectly squared assembly process. To give pilots effortless access to core avionics, the internal spacing between the 2mm thick top and bottom center plates has been expanded to a generous 28mm clearance. The upper platform board comes pre-drilled with precise mounting layouts tailored for popular edge-AI computing platforms—including the Raspberry Pi 4 and NVIDIA Jetson Nano—alongside native layouts for standard Pixhawk flight controller baseboards and GPS modules.

For payload carriage and balance, the frame features an enlarged, adjustable battery mounting deck equipped with dual heavy-duty hook-and-loop straps to accommodate high-capacity batteries for extended flight times. Slung underneath the main chassis is a dual 10mm diameter, 250mm long rod rail mounting system. This industry-standard layout is instantly compatible with a vast ecosystem of professional camera gimbals, mapping cameras, cargo drop boxes, and depth-sensing arrays (such as the Intel RealSense or Structure Core series via optional mounts). Completed by an impact-resistant, high-clearance carbon fiber landing gear structure, the X500 V2 delivers the open-source flexibility and commercial durability demanded by drone developers worldwide.

Hardware Configuration Note: This product is the standalone Frame Kit (Frame Only). It does not include motors, electronic speed controllers (ESCs), a power distribution board, propellers, flight controllers, or telemetry radios. All propulsion and avionics components must be sourced and configured separately.
