Multirotor aircraft are chosen when the work needs the aircraft to stay in one place — hover, look closely, carry something, or reposition in seconds. Sizing one comes down to three things: payload as a system budget, endurance under the real load, and what the operating environment removes from both.

A fixed-wing covers area faster but cannot hold position; a multirotor holds position and pays for it in endurance. The pages below make that trade explicit before you send an enquiry rather than after.
