you have two flagged propellers aiming forward with opposite sense

you move them to the sides so now they have THE SAME SENSE

this works in space as well so momentum can be created

whats wrong with this?

Everything. It's gibberish as normal.

saying everything is like saying nothing

the concept cant be simpler at least you dont pretend not to understand

edit:

you know the story of the emeperors clothes?

why should i trust a system that made whole countries into camps?

in fact i should belive from it opposite of what it tells me

you trow a ball nw YU HAVE MOMENTUM! HOW CAN TIS BE? PHYSICS ARE ALL WRONG!

Because there are forces and moments which are not really the same thing in that sense. You have strong forces between the propellers when the plane (read direction) of rotation changes, but the forces are in opposite direction through the physical structure and cancel each other.

You have not eliminated the forces, it goes through somewhere, even on diffeent wings for contrarotating, the airframe absorbs the forces through wings and structure, in some cases the forces are equal and in opposite directions.

Nothing disappears, nothing wrong. You get to look into what's happening in a gyro more in details. Don't see any question really.

nope you get pushed backwards with identical momentum the ball acquires but opposite sense, so net momentum remains zero as it started

my point is pretty clear in this drawing:


take the mass of the wizard neglectable(what brings down your point) compared with the propellers

Unless you make or write something clear no point to go further

the wizard has two counterorating flaged propellers aiming up while he floats in space

he puts the arms in cross so now the propellers have same sense

momentum has gone from zero to a big amount in an isolated system

if you dont understand this i will know youre pretending

This is very basic. If you don't have further questions let this topic end here.
