Hovering
To hover the quadcopter, the weight of the drone must be equal to all the upward forces of the propellers, where the movement must be equal to zero:
For flying, the upward force must be greater than the weight. So, if we subtract the mass of the drone from the upward forces of the propellers, we will get the equation of motion of the drone flying. Let's say it is 
. So, we can write:
