In above figure, propellers are looking same but both are different, both are mirror images of each other. We need to be aware about shape of propeller because propellers may look the same but they are not actually same, they may be mirror images of each other like our hands are mirror images of each other but they are not same. Propeller’s position plays important role in flight of drone. Kp = for midsized propellers Kp value is 1.2 To fly quad copter, we need 1:2 ratio for weight and thrust. If we want to fly the drone stably with heavy object then we should use that motor which manages less revolution but provides more torque for which high pitch propeller should be used. A high RPM provides more speed and maneuverability but lifts less amount of weight. If we use a higher pitch propeller for the same diameter, the propeller will generate more thrust and lift more weight but it will also require more power. Diameter gives area but pitch gives an effective area.
We are using (10*4.5) dimension propellers which mean its diameter is 10 and pitch is 4.5 inches.
Propellers come in many sizes and shapes. Here, we are using four brushless motor, which have 1000 Kv rating.Ī Propeller is mounted on top of each brushless motor.
It means motor will spin at given RPM (revolutions per minute) if we give V voltage to motor without any load. We will connect these three wires with electronic speed controller (ESC).īrushless motor comes with Kv-rating. In the image given below. we can see 1000KV BLDC motor which has three input wire. Also, there is no power loss due to brush transition. Brushless DC motor spins at a much higher speed and uses less power than DC motor (at same speed). It means, the wires can go directly to them and therefore there is no need for a brush. They contain a number of magnets mounted to a cylinder on outer side, which is attached to the rotating shaft. They have coils at the center of the motor, which is fixed to the mounting. Brushless motors don’t have these brushes. DC motor consists of coils and magnets which are used to drive the shaft and there is a brush over the shaft which takes care of switching the power direction in the coils. We have used brushless DC motor (BLDC) here. We are using screws of type m2.5 size, which are socket head screws or allen screws. F450 arms are reinforced to prevent any damage we can easily place the motor at the edge of the arms. It has two plates, one plate with the integrated PCB, so we can directly solder the ESCs. It is made of glass fiber and durable nylon. We are going to use f450 with the width of 450mm. In the image given below, we can see frame of quad copter. It consists of a center plate to which the electronic components and the four arms are attached to the center plate. The frames should be rigid so that it minimizes the vibrations from the motor. Components Required for Building Quadcopterįrame is the basic structure of the drone on which all the component are mounted together. Quad copter depends on electronic sensors like accelerometer and gyroscope and control system to stabilize flight. Yaw control authority is identical for both configurations but the pitch and roll control authority is up to about 30% greater in case of cross configuration. Both the shapes are stable but in forward flight, quad copter requires a yaw control input in forward flight. In this tutorial, we will design a quad copter of X-shape.

1- Plus configuration quad copter and 2- Cross configuration quad copter. Quadcopter stabilize its flight using electronic sensor and control system. What is Quadcopter?Ī quad copter is a multi rotor drone with 4 motors attached. In this article, we will learn how to design the quad copter (drone) using KK2.1.5 flight controller with the help of motors, flight controller, and chassis. These are used for rescue operation, delivery, surveillance, defense, medical and agricultural purposes, etc. The main advantages of drones are compact size and easy controlling. Quad copter is a type of unmanned aerial vehicles (UAV) or drone being used on large scale.
