Okay, thanks, I think I get it. Gonna dig further into this to wrap my head around it.

Great question OP!
Pretty much everyone has given bits and pieces of the aswer here. I don't have the time to be specific right now but essentially you have several forces at play and the most prevalent in your example is centripetal force caused by a rotating body!
Fc(ma)=mv^2/r
The Fc in this example is Fgrav (Gravitational Pull/Acceleration/Fa) provides this centripetal force! All bodies including the helicopter and atmosphere etc experiences this force. BTW, Tangential to Fgrav is the V(velocity) of the rotating body. When Fgrav and V are perpendicular it means you have a body at constant velocity(Everything is spinning at the same speed means everything might as well be stationary! The key to your query!)
Blah blah blah
Now using Universal Gravitational Law we get
Fc(ma)=GMm/r^2
mv^2/r=GMm/r^2
Canceling out and solving for v we get
v=SrqRoot GM/r
This equation tells us that all objects orbiting in our atmosphere(technically) and space at a certain distance orbits at the same velocity as the earth. Your helicopter and the atmosphere(the air molecules etc) and anything else on earth "orbits or spins" at the same velocity!
Now, Why is that?
This my friend enters the realm of Einstein specifically General Relativity( Curvature and Gravitational Frame) NOT Special Relativity which factors Light and Frames of Reference.
hope that helps for now...Gotta go! Check back on this thread later.....

Of course. Centripetal force.
I was thinking on a smaller scale of aerodynamics since OP was mentioning an "hovering" object in relation to the Earth's rotation.
There's gotta be a bar joke/bet in this like "I bet you I can fuck pussy at more than a thousand miles per hour"
now you can use that saved money to buy a helicopter.....lolWell...I just saved a bunch of money on my college tuition by asking BGOL.
If I remember correctly, I think what some are missing is atmospheric pressure. Even while hovering, air pressure along with gravity keeps you in relation to the Earth while its spinning. Like a fish in a fish tank, or fruit in a bowl of jello. The further up you go, the less air pressure from above you. Thus you start to get into the jet stream and such which is a result of the rotation. Thats why it takes more fuel for jets to fly from east to west than the other way around.
Something else to consider, people near the equator are moving at a greater velocity than those near the poles. A key reason why rocket launches are done in Florida. It starts at a greater velocity to help it reach orbital velocity before even taking off. The earth gives it an extra "push".

for saving me some 
If you don't know this by now, you will never ever ever know this. Carry on with your life.
Total ownage but then again how many of the flat earthers are even smart enough to understand how dumb dude made them look...
If you were at relative rest with the earths rotation you'd literally teleport because you'd move so fast but other forces like gravity cuts the equation and plods us along...just like the magnetic fields keep our asses from being barbecued. Deuces

Thanks. I had to take some time to digest that.
Another question.
So since the sun travels at 486,000mph,
and the earth orbits the sun at 66,600mph,
and the earth spins on it's axis at 1000mph,
and the moon orbits the earth at 2,288mph,
once a spaceship leaves the earth's atmosphere on it's way to the moon, I'm assuming it's the vacuum of space, so is there another gravitational force that keeps the spaceship within the orbit of the earth/moon around the sun?
With the earth and celestial bodies traveling that fast, how do they not leave the spaceship way behind once it's in the vacuum of space between the earth/moon?
Bruh the only accurate serious responses you got were from selfscience. Just pm him. Amd Tical.
Because the ship is still tethered to the gravitational pull of the earth, sun and other objects.. Keep in mind just because that ship is being impacted by the gravitational pull of the earth (locking it in place even in the vacuum of space) it is still being affected by the Sun, our galaxy and other forces of gravity forming a pulling in force that is offset by centrifugal forces that is trying to fling us away from the body that we are orbiting...
As the result, as long as we keep rotating at a certain speed and as long as the power of the gravity is balance, it will cause the shit to be lock into place forming a matrix where everything is moving at the same speed...
Think of being on a carousel where if you were to get off one of the horses and walk to the next it wont be that much of a problem, the centrifugal force may pull you towards the outer circle if too fast, but as long as your moving a slow enough pace you should be ok...
Plus while you are on a horse looking at other moving horses it may appear that they are not moving at all (remember your movement is relative) now if you were to attempt to move off the moving carousel (or the matrix that encompass the horses on that ride) you will be thrown to the non moving ground by the force force of the moving ride....
Now imagine placing a working replica of the carousel on the real one and having them both spin at the same time, you can imagine how that as long as you are on the tiny replica the movement of the larger carousel should not be a factor at all (that is if you had a force like gravity pulling you in negating the pulling away forces exerted by centrifugal force..
The reason why you wont find a neutralizing gravitational force on the carousel, the way you'd experience in space, is due to there not being objects large to fight the forces of the centrifugal force.. But hypothetically speaking if there were strong enough gravity force pulling you towards the center, then the problems you would experience with the walking around on a carousel, especially one that is moving fast, will all go away, that's providing that the centrifugal force pulling you off the ride matches or is close to the pull of gravity pulling you in towards the middle.
Another thing that I thrown out for the sake of simple discussion is Dark Matter... Well that's a long story on its own, but lets cut it short by saying it also keeps things (big things such as stars) in place preventing them from being flung into space by the centrifugal forces of the galaxy...
Another good series of questions. Road-rage did a good job of explaining the general theoretical principles. If that will suffice then great! If not or you just want more then I can try to supplement this thoughts with some diagrams and more math.
Where did Roadrage explain this?
Lmaoooo @ jumping in a elevator
I take it you didn't like what i said?
We are all saying the same thing basically there are two forces at play ccentrifugal force pulling everything away from the orbit vs gravity trying to pull thing towaards the center of the orbit... And as long as those forces are equal or close to being equal, we are locked into position similar to everyone in a car thats moving 80 mph..
A even simpler way of looking at it would be a giant plane flying and a smaller plane flying inside and a microscopic plane flying in that one, as long as each plane is a closed system, the smallest plane will not notice the movement of the largest plane that they are all in... Of course thats way simplified but at least you should be able to wrap you head around systems moving fast in moving systems and not being impacted or noticing the movement of the other systems..
oh my bad, I forgot I had blocked Roadrage
LOL!! Is the BOB dude serious?
For the record, I'm not asking these questions because I'm trying to prove any flat earth theory. I don't know why there are all these references to flat earth because I didn't say anything about that.
