How can I confirm that an accessory is compatible with my drone?

Check the exact drone brand, model number, hardware version, dimensions, connector, voltage, battery type, and other specifications shown on the product page. Similar-looking parts may not be interchangeable. Contact us before ordering if compatibility is unclear.

Do I need to register my drone with the FAA?

Registration requirements depend on the drone’s weight, equipment, and intended use. Certain drones operated in the United States must be registered and may need to comply with Remote ID requirements. Review current information at the official FAA website before flying.

How long does order processing and delivery take?
