What is the heaviest weight a legal drone can be without special permits?

The maximum weight a legal drone can operate under the FAA's Small UAS Rule (Part 107) without requiring special permits is 55 pounds, including the weight of the drone and any payload it carries. This regulation is crucial for ensuring safety and compliance in the national airspace system. Drones weighing more than this limit fall under different regulations that often require additional certification and operational restrictions. Understanding this weight limit is essential for any operator to avoid legal issues and ensure compliance with FAA rules when flying unmanned aircraft.
