When I first saw this, I thought there was no way in hell you would get enough lift off a helicopter to fly in a 100th the pressure of Earth. This is the equivalent of flying a helicopter 3x higher than Mount Everest!!
Turns out, with big ass scoopy propeller blades, its actually not that much harder than building a conventional drone.
I've still got an awful lot of skepticism if this thing is possible thought. I have doubts if they will ever be able get enough power to run it as an autonomous unit off less than 1 Watt of continuous power. There are also horrendous heat flow problems. It runs for about 2 minutes per day, and does nothing for the remaining ~24 hrs. So it has to be well enough insulated that it doesnt freeze during 24 hrs on inaction, but not so well insulated that it frys on its 2 minutes of burst power!.... Thats a nightmare problem to try and solve!
