1. How do I choose DIY Drone parts?

There are various types of Components used in a DIY Drone. Choosing Quadcopter parts is easy if you have the basic understanding of quadcopter.

• Choosing a Frame: Quadcopter frames have significant impact on flight performance: aerodynamics, weight distribution, rigidity, etc, all play a part in flight characteristics. A mini DIY Drone frame can be made from any material you can possibly think of: Wood, 3D printed plastic, plastic, fibre glass, aluminium, or even PVC pipes. However, carbon fiber remains the most popular material as it is electrically conductive and blocks radio frequency signals.

          The size of a frame determines the choice of most of the components you will use in the build. A more powerful DIY Drone requires a                 larger frame for longer propellers and larger motors, while a smaller frame will use shorter propellers and smaller, less powerful motors.

• Flight Controller: The Flight Controller is the brain of a quadcopter, it has sensors like Gyroscope, Accelerometer, Barometer and Magnetometer on the board. Using the sensor data, it then controls the speed of the motors to make the craft move as instructed. Most of the wiring on quadcopter will be focused around the FC. It needs to have the RX (receiver) connected, so it can be told what the pilot wants the craft to do.
• Electronic Speed Controller: An ESC is a device which is used to control the speed and direction of brushless motor. The ESC receives throttle signals from the flight controller and drives the brushless motor at the desired speed. Using good quality ESC’s means you should have a reliable and smooth flight experience. The first thing to look at when choosing ESC is the current rating.
• Motor: Getting an efficient combination of propeller and motor is very important. Motor speed is rated in kV, generally a lower kV motor will produce more torque and a higher kV will spin faster, this however is without the propeller attached. There are many aspects to motor performance aside from raw thrust, high among these is how much current the motor draws from the battery. Remember to check the specs of your motors for their maximum amp draw and ensure that your ESC’s are rated to withstand this amperage.
• Propellers: The propeller acts as wings of the flight. It pulls the air downwards and makes your DIY Drone fly. Almost, in every size, there are different types of propellers are available. Propellers largely affect the quadcopters flying speed, it's load and the speed at which they can maneuver. According to these attributes, you can decide the length and pitch of the propellers. The pitch is the shape and slant of the propeller. A heavier propeller will require more torque from the motor than a lighter prop, also blades with a higher AOA (Angle of Attack) encounter more resistance from the air and require more torque.
• Transmitter and Receiver: A radio transmitter (TX) is used to control a DIY Drone remotely. The user commands are then received by the radio receiver (RX) which is connected to a flight controller. A radio transmitter should be one of the very first items to buy when getting into FPV, as you can use it to play with DIY Drone simulators before even owning a DIY Drone. Unlike many other components and accessories that are more likely to break or become obsolete, a good radio transmitter will follow you for many years.
• Battery: LiPo batteries are the power sources of the quadcopters. LiPo is used because of the high energy density and high discharge rate. The battery is the single heaviest component of your quad, just because you put a bigger battery on it, it doesn’t mean it will fly longer. So, you need to choose the battery according to its size, capacity, C rating, its voltage etc.
