**4. Configuration and assembly methodology**

Assembling a quadrotor requires several steps, from assembling the chassis and the electronic components, to calibrating and finalizing the vehicle. Before explaining, we will present the tools used for assembly. This part describes the interconnection of electronic components and the assembly of the chassis without electronic components [17].

#### **4.1 Connection and wiring of components electronic**

Assembling a quadrotor requires several steps, from assembling the chassis and components, to calibrating and finalizing the vehicle. Before explaining, we will present the tools used for assembly. This part describes the interconnection of electronic components and the assembly of the chassis without electronic components as is shown in **Figure 2** [17].

#### **4.2 The assembly frame alone**

To assemble the vehicle frame, we follow the steps below:


#### **4.3 Complete assembly with electronic components**

This part describes the complete assembly of the sk450 quadrotor frame, including the assembly of the flight controller and electronic wiring.

#### *4.3.1 Motors mounting*

The motors are mounted in the correct order at the ends of each arm using a motor plate. The rotation of the motor changes according to the choice of user and gives the vehicle certain movements (Take off, landing, Throttle, yaw, pitch, roll, etc.).
