Drone Building Course

Lesson 1 • Core Physics of Flight

Covers lift, thrust, drag, and torque as they apply to rotary-wing aircraft. Provides the aerodynamic reasoning behind component selection in later chapters.

Lesson 2 • History and Types of Drones

Traces drone evolution from military origins to consumer use and maps major airframe categories. Establishes context for design choices made throughout the course.

Lesson 3 • Drone Anatomy Overview

Identifies every major subsystem: frame, motors, ESCs, flight controller, power, and communication. Gives students a shared vocabulary used in all subsequent chapters.

Lesson 1 • Frame Assembly Workflow

Walks through a step-by-step build sequence from bottom plate to arm attachment and canopy fitting. Reinforces correct order of operations to avoid rework.

Lesson 2 • Frame Materials and Properties

Evaluates carbon fibre, aluminium, and injection-moulded plastics for stiffness, weight, and cost. Connects material choice to vibration damping and crash resistance.

Lesson 3 • Tools and Fastening Techniques

Covers essential hand tools, torque specifications, thread-locking compounds, and standoff hardware. Proper fastening prevents in-flight structural failures.

Lesson 1 • Brushless Motor Fundamentals

Explains KV rating, stator dimensions, pole count, and efficiency curves for brushless motors. Provides the selection criteria applied when specifying motors for a build.

Lesson 2 • Propeller Selection and Matching

Covers diameter, pitch, blade count, and material for propellers and their interaction with motor KV. Correct matching maximises efficiency and reduces motor stress.

Lesson 3 • Thrust Budget and System Matching

Teaches thrust-to-weight ratio calculation and full-system power draw estimation. Ensures the propulsion system meets hover efficiency and maximum thrust targets.

Lesson 4 • Electronic Speed Controllers

Details ESC current ratings, firmware types, BEC output, and communication protocols. Students select and configure ESCs compatible with their motor and flight controller.

Lesson 1 • Battery Charging and Storage Safety

Details balance charging, storage voltage, temperature limits, and fire-safe handling. Prevents battery failures that are a leading cause of drone fires and crashes.

Lesson 2 • Power Distribution Design

Covers power distribution boards, bus bars, capacitor placement, and voltage regulation. Proper distribution prevents voltage spikes that damage ESCs and flight controllers.

Lesson 3 • Alternative Battery Technologies

Surveys Li-Ion, LiHV, and solid-state cells as alternatives to standard LiPo packs. Helps students choose chemistry based on energy density and safety priorities.

Lesson 1 • PID Tuning Fundamentals

Explains proportional, integral, and derivative gains and their effect on drone response. Students apply systematic tuning methods to achieve stable hover and crisp control.

Lesson 2 • Flight Controller Hardware

Compares processor architectures, IMU sensor quality, barometer, and onboard OSD chips. Hardware selection determines the ceiling of achievable flight performance.

Lesson 3 • Fail-Safe and Flight Mode Setup

Configures fail-safe behaviours, arming switches, and flight mode channels on the controller. Proper setup prevents flyaways and enables safe recovery from signal loss.

Lesson 4 • Sensor Calibration and Configuration

Covers accelerometer, gyroscope, compass, and barometer calibration routines. Accurate sensor calibration is mandatory before any flight attempt.

Lesson 1 • Transmitter and Receiver Setup

Covers transmitter model profiles, channel mapping, binding procedures, and receiver mounting. Correct setup ensures all pilot inputs translate accurately to flight controller commands.

Lesson 2 • Video Transmission Systems

Compares analogue and digital FPV video links for latency, range, and image quality. Students select and install a video system matched to their flying style.

Lesson 3 • Telemetry Systems Integration

Integrates MAVLink or proprietary telemetry modules for real-time flight data on the ground station. Telemetry enables in-flight monitoring and mission adjustments.

Lesson 1 • Camera and Gimbal Integration

Covers gimbal motor types, stabilisation axes, and camera trigger interfaces for aerial imaging. Proper integration delivers vibration-free footage and precise shutter control.

Lesson 2 • Obstacle Avoidance Systems

Introduces ultrasonic, infrared, and stereo-vision sensors for collision detection and avoidance. Sensor placement and firmware settings determine avoidance effectiveness.

Lesson 3 • GPS and GNSS Integration

Covers multi-constellation GNSS modules, compass interference, and RTK positioning for centimetre accuracy. GPS is the primary enabler of autonomous navigation features.

Lesson 4 • Optical Flow and Rangefinders

Explains optical flow sensors and downward-facing rangefinders for indoor position hold. These sensors compensate for GPS unavailability in confined environments.

Lesson 1 • Advanced PID and Filter Tuning

Refines RPM filters, notch filters, and PID gains using log data for race or cinematic profiles. Optimised tuning maximises responsiveness whilst eliminating oscillation.

Lesson 2 • First Flight and Hover Test

Guides a controlled maiden flight sequence from low hover to basic manoeuvres in open space. Identifies gross tuning errors and mechanical issues under real flight loads.

Lesson 3 • Vibration Analysis and Damping

Uses black-box logs and FFT analysis to identify vibration frequencies from props and motors. Targeted damping solutions improve sensor accuracy and extend component life.

Lesson 4 • Systematic Fault Diagnosis

Applies root-cause analysis to common failures: motor desync, ESC cutout, GPS glitch, and power brownout. Structured diagnosis reduces repair time and prevents repeat failures.
