Yes, the ability to hover is a really big deal.
Kalman filtering. Who knew?
GPS, compasses, intertial navigation, redundancy. Great stuff.
NZ showed DJI that quadcopters were the way to go.
The importance of brushless motors.
It is really amazing how quickly quadcopters took over from ordinary helicopters. The regs in the DC area that prevent us from flying quadcopters here were probably developed BEFORE the quadcopters were developed.
I still wonder about why we still fly normal helicopters: Take you hands off the controls of a helicopter and it will soon start to flip and fall. Take you hands off the controls of a quadcopter and it will just hover in the sky. When the batteries get low, it will return to the start point and land.
I have a video taken by my Hanmilt drone on my Patreon channel. I have already bought a DJI Mini 4K to fly in the DR.

Very interesting video. I spent some time with the DJI Phantom creating maps out of photos, and performing equipment inspections. Never dug into the history behind DJI. A real success story.
