Why doesn’t it spin independently of me and I end up in another country or something? And if a spaceship watched earth from afar, at one point would it start spinning with earth and at what point can it observe the rotations of earth without being part of it?

The earth is spinning and the helicopter is “Along for the ride”, moving with the earth. When it lifts off that momentum stays with it. It’s already up to speed and going the same direction as the earth.
It’s similar to when you throw a ball. The ball leaves your hand but continues at a speed similar to what your hand was traveling before you let go. That’s how throwing works.
