I'm exploring the use of drones to do delivery (for items that weigh up to 20kg
ie about 44 lbs) of dimensions up to 2ft long x 2ft wide x 10 inches thick.
Once local authority approves it, thought of sourcing/purchasing some of these
drones but will need to look into the cost effectiveness (ie its gasoline/petrol
costs, maintenance/repair) or is there any that uses rechargeable powerbanks?
Has Amazon or any country done it & what's the safety & regulatory requirements?
