This has nothing to do with aerodynamics.
In a vacuum, which is 0 grams of anything in M3, you cant fly anything.
It is marvelous that the 13 grams of Co2 molecules in one M3 is enough for a craft to generate any lift on Mars. Its actualy in my view impossible.
This nasa helicopter can in my view be max 25 grams for it to fly. And have the same lift capability of this 1.7kg version.

You seem to be only taking into consideration a gravity conversion.
If 1kg can fly on earth, then it can weigh 2.63kg on Mars to also fly.
Yes. If the atmosphere is as thick. If there are about 150 times less molecules in M3, how can it fly there. Does it not matter even a bit?

How. Mars is according to official studies 6-9mbar. That space magazine says the same.
Im saying its a lie nothing this size can fly in that kind of almost vacuum.
How is this not even at a little level linear:
You people must now think out of the box and think the possibility that the Nasa vacuum test was a lie for the following example to work:
You cant accept their claim, the stripped down 750g version (of the chopper) flew in the supposed vacuum chamber. Forget that for a second.
Lets go by the following theoretical test:
Earth gravity and 1000mbar and 1kg machine creates X amount of lift.
A "test planet" with a gravity (38% of 100% earths) and a pressure of 380 mbar (which is also 38% of earths), and a 1kgs machine creates X amount of
lift.
And X is the same. That would make sense. Even at some level if not totally linear.
Since pressure is 2.6 times smaller, the craft would need to create 2.6 times more lift. But I cant. But, because gravity is reduced also 2.6 times,
it actually manages to get to air even with a smaller lift.
notice: mars has 38% gravity of earths so test planet is mars with a higher atmosphere.
How can Nasas thing fly at 6-9mbar, (11-13 grams of Co2 in m3).
It means, Nasa chopper should be able to lift: 30 times its weight on Earth.
But it cant even lift itself on earth.
See what im getting at? Theres worlds largest conspiracy at play at Nasa and its so big no one can even fathom its size.
