CNC Cut 3K Carbon Fiber Drone Frame Kit

Frame parts are nested on full sheets to reduce waste, then cut on CNC routers with diamond-coated tooling. Motor-mount hole patterns and stack mounting holes are drilled in the same program as the outline, so they stay true relative to each other. Arms receive chamfered edges to protect wiring and reduce crack starts. Pockets for weight saving can be partial-depth on thicker plates.

3K twill sheet is the common choice for frames, offering high stiffness-to-weight and a familiar finish. Arm thickness of 4–6 mm is typical for 5-inch FPV frames, while plates run thinner. Carbon is conductive, so edges near wiring should be chamfered or sealed. Matching aluminum standoffs, motor mounts and arm clamps can be machined alongside the carbon parts for a complete kit.

First-article frames are dry-assembled to confirm hole alignment between plates and arms. Each part is checked for delamination, edge chips and face scratches, and critical hole positions are measured on every batch. Typical uses include FPV racing and freestyle frames, cinematic lift frames, mapping UAV airframes and payload mounting plates.
