Helicopter lift is a well known equation you can play with at home.
Figure out the coefficient of lift, the hardest figure out since it's based on blade design.
Multiply that by surface area, fun fact modern helicopters are so heavy the flexible blade bends into a downward cone, losing up to 5% of it's surface area.
Multiply that by one half of air density. This is also what creates a flight ceiling, and low moisture and tempatures actually improve air density.
Finally multiple that by velocity squared, which is the largest variable used for helicopter flight.
As long as Lift exceeds your weight, you fly upwards. And that's all there is to it.
Something worth noting is how air density is halved, a '100' reduced to '50' isn't a 50% loss but 25%. Likewise velocity is multipled by itself, increasing speed from a '5' to a '7' isn't a two point gain, it's nearly doubled. The blade speed is extremely important.
It's also why those $5 helicopter toys suck. They have one speed, quickly moving high into the air from the higher lift generated while taking off. Their upwards speed actually pushes them higher than than they should go so they start to fall back down, zig zagging up and down (often crashing) because they don't softly adjust their speed like pilots have to. It's a lot like taking a ball and holding it down in a pool, letting it go makes it shoot clear out of the water and then it falls back in and bobs for a bit. For thirty bucks you can get a super basic cheap helicopter toy that lets you control velocity, allowing you to control the fourth part of the equation and achieve smoother flights.
Then you can work on moving up to larger, more expensive, drones as you start to grasp the basics of flight. It's how most people are learning about helicopters these days.
