Drone in 1925: Drone milestone 4

Fixed-wing vs multirotor splits endurance and launch needs. Flight controllers, GNSS spoofing resistance, detect-and-avoid and battery thermal runaway rules define legality. Remote ID and geofencing are airspace systems as real as airframes. Hobbyist parks and wartime footage collide in the public mind.

Privacy panic and delivery-hope marketing fight for the narrative. Consumer race-to-bottom pricing sits beside defence megacontracts. Insurance and municipal permits gate commercial fleets. Drone engineering is a stack of structure, energy conversion, control loops and certified envelopes inside the air atlas. This page maps how loads travel, how power becomes motion, and where the hard limits sit.

Arm tubes carry motor thrust into center plate; landing gear spreads touch-down loads. Fixed-wing wings bend under gust loads; torsion boxes resist washout in dive. Battery mass dominates endurance; solar HALE platforms are a separate class entirely. Swappable packs define commercial turnaround more than motor wear.
