Safety and compliance

What we do on our side, and what you are responsible for as a builder and pilot.

Remote ID (14 CFR Part 89)

Remote ID has been in full enforcement in the US since March 16, 2024. It applies to drones that require registration, which generally means anything at or over 250 g. Complete drones and complete build kits that we produce are covered by a Declaration of Compliance where required. Individual parts and components do not trigger these requirements on their own, but the aircraft you assemble may. You are responsible for registering your aircraft and broadcasting Remote ID where the rules apply.

Pilot rules

Recreational flyers operate under the exception for limited recreational operations, including the TRUST test. Commercial operation falls under Part 107 and requires a remote pilot certificate. Know the rules for the airspace you fly in before you take off.

Printed parts

3D printed parts are anisotropic: they are weaker along layer lines, and strength varies with material, infill, and print orientation. Everything we print is sold for prototyping, experimental, and hobby use. It is not certified for safety-critical or certified aircraft use. Inspect structural parts before and after every flight and retire parts that show cracks, delamination, or impact damage.

Firmware integrity

Every firmware release is published with a SHA-256 checksum and a signature, per release, per board target. Verify the checksum after downloading and before flashing. Releases we pull for defects are marked as withdrawn and stop being served. Firmware that controls an aircraft deserves the same care as the airframe: read the changelog, flash the exact target for your board, and reconfigure failsafes after major updates.

Export

Our hobby-class parts are commodity electronics. We do not ship to sanctioned parties or embargoed destinations, and some items may require export classification review for international orders. If you have an export question, contact us before ordering.

Batteries

Lithium polymer batteries are regulated as dangerous goods in transport. Charge them with a balance charger, store them at storage voltage in a fire-resistant container, and dispose of damaged packs at a battery recycling point. Never ship a swollen or damaged pack.
