Re: Hard to test this
have you seen a photo of it? The blades are long and wide and apparently fold up nicely for the trip to Mars. I think the total rotor diameter is over 1 meter, and they would have had to construct them from super-light-weight material, maybe like model airplane wings? [yeah I used to build those when I was a kid, paper and balsa wood]
Although i would expect carbon nanotubes from NASA...
(duckduckgo search, "mars helicopter photo", lots of hits, some with people so you can get a size reference)
