I installed the most popular utility drone motor on the most popular hobby helicopter for IOT/MQTT/COAP research to see what happened. It cruised for 35 minutes straight, breaking the world record of any commercial platform of 250 grams by 50+% extra flight time! The fuselage is Blade230 or BSR body, main motor is T-motor 4004 or Emax 2808 from Tarot 650 utility inspector drones. Main rotor is built from 180-250 sized helicopter parts. Flight computer and tail motor are taken from the popular racing quadcopter HGLRC Petrel 132. The fuselage is less than 7 dollars a piece. Wouldn't that be nice if highways are patrolled by camera drones to broadcast the video of traffic accidents, and an AI server phones motorists to get out of the highway at the immediate exit before lining up in a traffic jam?
Part listing is in the following table. Shipping discount for multiple items from a vendor has been applied. No volume discounts are used.
The entire craft can be built without a machineshop and hence can be repaired by gig workers in a car. Only light hand tools and light electric tools that can be powered from car battery are needed. This creates jobs.
