Replicant GEN 1​

Open Hardware (CERN-OHL-W v2.0)​

Replicant GEN 1 design files (including the airframe and the battery rail/mount that forms part of the drone) are released under the CERN Open Hardware Licence v2 — Weakly Reciprocal (CERN-OHL-W-2.0).

That means you may download, manufacture, modify, and sell drones based on these files. If you modify the licensed design files and then distribute those modified files or ship products based on your modified licensed design, you must make the corresponding modified design source for the licensed portions available under CERN-OHL-W-2.0, and keep the required copyright/licensing notices.

What's allowed
  • ✅ Download and use the design files
  • ✅ Manufacture drones for personal use
  • ✅ Manufacture and sell drones commercially
  • ✅ Modify the designs for your own needs
  • ✅ Distribute modified designs (under CERN-OHL-W-2.0)

Proprietary / Excluded (Battery Pack)​

The rail-mounted battery pack itself is not part of the open release. Battery pack design (cell configuration, wiring, electrical design, drawings, and any files explicitly marked "Proprietary") remains proprietary to Yirra Systems and is not licensed for copying, manufacturing, or redistribution without written permission.

Excluded from open license
  • ❌ Battery pack design
  • ❌ Battery pack cell configuration
  • ❌ Battery pack wiring
  • ❌ Any files marked "Proprietary"

No Warranty / Safety​

All materials are provided "as-is", without warranties of any kind. Building and operating drones is inherently risky. You are responsible for safe assembly, testing, operation, maintenance, and compliance with all applicable laws and regulations in your location.

Safety Notice

Building and flying drones involves significant risks including but not limited to:

  • Physical injury from spinning propellers
  • Fire hazard from lithium batteries
  • Property damage from crashes
  • Legal liability in your jurisdiction

You assume all responsibility for safe construction and operation.
