2. Commercial off the Shelf (COTS) drones


This category includes drones like the Phantom 4, Parrot Anafi, Skydio 2, and others that are designed to be stable and balanced out of the box. They don't have a Maximum Takeoff Weight (MTOW) specified, so adding weight to them is not recommended because it commonly impacts the drone's endurance, controllability, and stability. The Civil Air Patrol (CAP) is restrictive about allowing any modifications to stock COTS beyond minor additions like strobe lights for night operations, Remote-ID Broadcast Modules, or propeller guards.
