Battery life could be a problem unless there is a technology I don’t about regarding mini-copters. Average flight time about 7-15 mins max even with the highest output batteries.
Hmmmmmmmmmmm

That may be all the time they need to order up a colonoscopy. Stat!
There have been major battery breakthroughs with nanotechnology. This will soon cease to be a limiting factor.
