The Martian atmosphere is rather thin: when Aurora was working on a foldable, rocket powered Marsplane, the prototypes were test flown by taking then up to somewhat over 100,000 ft under a balloon and dropping them: the Martian atmosphere near ground level is very similar in pressure, density and temperature to our atmosphere at 100,000 ft. The Aurora tests, launched from Hawaii, were successful: by the time their marsplane and its balloon had reached around 105 Kfeet it was a good 100 miles downwind of the islands. After flying the test schedule the marsplane was down to just under 100 Kfeet and at least one of them was successfully glided back upwind and landed near its launch point in Hawaii.
What's the maximum altitude a DJI Mini has reached? I know that a DJI Mavic 3 drone has been flown from the summit of Mount Everest and successfully climbed another 400m, so to 33238 feet, but even a U-2 can only reach around 78,000 feet and Perlan 2, a high altitude pressurised glider, has reached 76,000 feet (23km) and has a designed maximum altitude of around 90,000 feet.
Both these aircraft have flown at twice the height that DJI Mavic 3 drone reached above Everest.
You'll have noticed that the Mars Heli was both carefully designed to save weight and has a much bigger rotor diameter than anything of similar weight that's usually flown here. The area of its rotor blades is a lot higher too: increasing both its rotor diameter and its blade area would be needed to fly in such a low density atmosphere as we find on Mars.
I expect that any COTS drone would not be able fly on Mars because its weight would be too high for its rotors, which are designed to fly in the part of our atmosphere that people can live in, to lift off the sands of Mars.
