How do I size a drone motor?
A good rule of thumb for a quadcopter is to aim for a 4:1 power to weight ratio. It is common to see that number double to 8:1 or more in racing quads. To figure your power to weight ratio, you will want to calculate the max static output of the motors divided by the weight of the quad.
How do you size a brushless motor?
The physical size of a particular brushless motor is usually indicated by a number that looks like this – ’22-05′. The first number, 22, indicates how wide the motor is whilst the second number, 05, indicates the hight. Usually, these are written on the motor casing themselves to show you how wide and high they are.

What is the structure of a quadrotor system?
The basic quadrotor structure used for the model development is shown in the figure above depicting the Euler angles of roll, pitch, and yaw, a body coordinate frame {b}, and the global coordinate frame {G}. This model relies on several assumptions:
How to develop accurate control systems for the quadrotor platform?
In order to develop accurate control systems for the quadrotor platform, it is necessary to develop and analyze the equations of motion that define the quadrotor system. The quadrotor is defined by a set of non-linear equations which make accurate simulation as well as control difficult.
How are the equations of motion in a quadrotor defined?
The quadrotor is defined by a set of non-linear equations which make accurate simulation as well as control difficult. Once all the components of the equations are developed, it is possible to simplify the equations of motion after making several assumptions about the method which the quadrotor will be operated.
How is the torque of a quadrotor calculated?
The torque due to drag is shown to be proportional to the product of a drag constant and the square of the rotor’s angular velocity. This drag equation assumes that the quadrotor is operating in stable flight and that the propellers are maintaining a constant thrust and not accelerating.
