Drone DIY Guide: Essential Terminology Every Builder Should Know

Introduction

The drone industry has grown rapidly in recent years. From FPV racing drones and long-range exploration platforms to professional UAVs and heavy-lift aircraft, custom drone builds have become increasingly popular among enthusiasts, engineers, and creators.

However, for beginners, building a drone can be challenging because there are many technical terms and electronic components to understand.

Before selecting motors, ESCs, batteries, or flight controllers, understanding the basic drone structure and terminology is the first step toward building a reliable and high-performance UAV.

In this guide, we will explain the most important drone DIY concepts and help you understand how each component works together.

1. What Is a Drone?

A drone, also called a UAV (Unmanned Aerial Vehicle), is an aircraft that can fly without a pilot onboard.

Drones are controlled through a combination of:

• Flight controller
• Sensors
• Electronic speed controllers
• Motors
• Radio systems
• Software

Modern drones are widely used in:

• FPV racing
• Aerial photography
• Industrial inspection
• Agriculture
• Mapping
• Search and rescue
• Professional UAV applications

2. Different Types of Drone Builds

Before building a drone, it is important to understand the different categories.

---

RTF (Ready To Fly)

RTF drones are fully assembled and ready for flight.

They usually include:

• Frame
• Motors
• ESCs
• Flight controller
• Receiver
• Remote controller

They are the easiest option for beginners.

---

ARF (Almost Ready To Fly)

ARF kits include most of the major components but require additional setup.

Builders may need to add:

• Battery
• Receiver
• Flight controller configuration

ARF provides more customization than RTF.

---

BNF (Bind And Fly)

BNF drones are usually assembled with a receiver installed.

Users only need to connect their own transmitter and configure the system.

---

DIY Drone (Do It Yourself)

DIY drones allow builders to select every component according to their needs.

Builders can customize:

• Frame size
• Motors
• ESC
• Battery
• Propellers
• Flight controller
• Camera system

DIY builds provide maximum flexibility and performance.

3. Common Multirotor Drone Types

Quadcopter

The quadcopter is the most popular drone design.

It uses:

• 4 motors
• 4 propellers

Common configurations include:

X Configuration

The front direction is between two arms.

Advantages:

• Balanced control
• Popular for FPV drones
  
  
  

---

Plus Configuration (+)

The front direction points toward one arm.

Advantages:

• Simple layout
• Good visibility for cameras

---

Hexacopter

A hexacopter uses:

• 6 motors
• 6 propellers

Advantages:

• Higher lifting capability
• More stable flight
• Suitable for professional applications

---

Octocopter

An octocopter uses:

• 8 motors
• 8 propellers

Commonly used for:

• Heavy payloads
• Professional cameras
• Industrial UAV systems

---

4. Main Components of a Drone

A drone is a complete system where every component affects performance.

---

Frame

The frame is the physical structure of the drone.

It supports:

• Motors
• Electronics
• Battery
• Camera equipment

Drone sizes are usually classified by frame size:

• 3-inch drone
• 5-inch FPV drone
• 7-inch long-range drone
• 10-inch heavy-lift drone

Larger drones usually require stronger motors and higher-current electronics.

---

Brushless Motor

Brushless motors are the power source of modern drones.

Compared with brushed motors, brushless motors provide:

• Higher efficiency
• Better durability
• Higher power output
• Lower maintenance

Motor selection depends on:

• KV rating
• Battery voltage
• Propeller size
• Drone weight

---

ESC (Electronic Speed Controller)

The ESC is one of the most important components in a drone.

Its main function is controlling the speed of brushless motors according to commands from the flight controller.

A good ESC provides:

• Smooth motor response
• Stable operation
• High current capability
• Protection features

For different drone applications, ESC selection is critical.

Small FPV drones may use lightweight ESCs, while larger UAV platforms require high-current ESCs capable of handling greater power demands.

---

What Is an AM32 ESC?

AM32 is an open-source ESC firmware designed for brushless motor controllers.

Compared with traditional firmware, AM32 provides:

• Flexible configuration
• Adjustable parameters
• Efficient motor control
• Support for modern drone applications

AM32 ESCs are becoming popular among FPV pilots and UAV builders who want more control over their power systems.

• Gyroscope
• Accelerometer
• GPS
• Receiver

It controls:

• Motor output
• Flight stability
• Navigation functions

Popular flight controller firmware includes:

• Betaflight
• iNav
• ArduPilot

---

Battery System

The battery provides power to all drone components.

Most drones use lithium batteries, especially:

LiPo Batteries

Advantages:

• High discharge rate
• Lightweight
• High power output

Battery specifications include:

Voltage (S Rating)

Examples:

• 4S
• 6S
• 8S
• 12S

Higher voltage systems are commonly used for larger drones.

---

Capacity (mAh)

Determines flight time.

Higher capacity provides:

• Longer endurance
• More weight

---

Discharge Rating (C Rating)

Determines how much current the battery can provide.

---

5. How Drone Power Systems Work

A drone power system works through a simple process:

Battery
↓
ESC
↓
Motor
↓
Propeller
↓
Thrust

The battery provides electrical energy.

The ESC controls motor speed.

The motor converts electrical energy into mechanical power.

The propeller generates thrust to lift the drone.

Each component must be correctly matched for safe and efficient operation.
