Lesson 1 • Power Distribution Systems

Covers power distribution boards, ESC wiring, and voltage regulation components. Enables technicians to trace power faults from battery to motor.

Lesson 2 • Battery Handling and Storage Safety

Establishes safe procedures for charging, storing, and disposing of drone batteries. Directly reduces risk of thermal runaway and fire incidents.

Lesson 3 • Electrical Fundamentals for Technicians

Reviews voltage, current, resistance, and power as applied to drone circuits. Grounds all subsequent electrical diagnostics in measurable quantities.

Lesson 4 • Electrical Testing and Measurement

Applies multimeters, battery analyzers, and oscilloscopes to drone electrical systems. Builds diagnostic skills used throughout all subsequent maintenance tasks.

Lesson 1 • Electronic Speed Controllers

Details ESC hardware, firmware, and communication protocols including PWM and DSHOT. Enables technicians to configure, calibrate, and update ESC firmware.

Lesson 2 • Propulsion System Diagnostics

Applies motor test stands, current meters, and vibration analysis to identify faults. Connects diagnostic findings to corrective maintenance actions.

Lesson 3 • Propulsion Optimization Techniques

Balances propellers, adjusts motor timing, and tunes ESC parameters for efficiency. Prepares students to tailor propulsion systems to payload and endurance requirements.

Lesson 4 • Propeller Design and Selection

Covers pitch, diameter, blade count, and material trade-offs for drone propellers. Links propeller choice to motor load, efficiency, and flight time.

Lesson 1 • PID Tuning Fundamentals

Introduces proportional, integral, and derivative gains and their effect on flight response. Proper PID tuning eliminates oscillation and improves payload stability.

Lesson 2 • Flight Controller Hardware

Identifies processor types, IMU sensors, and peripheral ports on common flight controllers. Establishes hardware literacy needed for firmware and sensor work.

Lesson 3 • Inertial Measurement and Sensor Fusion

Explains accelerometers, gyroscopes, magnetometers, and barometers and how they combine. Sensor fusion accuracy directly determines flight stability and autopilot reliability.

Lesson 4 • Firmware Installation and Configuration

Guides students through flashing, configuring, and validating flight controller firmware. Correct configuration prevents crashes caused by miscalibrated sensors or wrong frame types.

Lesson 1 • Antenna Selection and Placement

Evaluates omnidirectional and directional antennas for range, gain, and polarization. Proper antenna choice and placement maximize effective communication range.

Lesson 2 • RC Transmitter and Receiver Systems

Explains binding, channel mapping, failsafe configuration, and diversity receivers. Correct setup prevents loss-of-control events during signal degradation.

Lesson 3 • Telemetry Systems and Data Links

Configures bidirectional telemetry for real-time flight data and ground station integration. Telemetry enables remote diagnostics and mission monitoring beyond visual range.

Lesson 4 • Radio Frequency Fundamentals

Covers frequency bands, wavelength, propagation, and interference relevant to drone links. Provides the RF theory needed to diagnose range and reliability problems.

Lesson 1 • Structural Inspection Techniques

Applies visual, tactile, and non-destructive inspection methods to detect cracks and delamination. Early detection prevents in-flight structural failures.

Lesson 2 • Airframe Materials and Properties

Compares carbon fiber, aluminum, and polymer composites for weight, stiffness, and repairability. Material knowledge guides component selection and damage assessment decisions.

Lesson 3 • Weight and Balance Calculations

Calculates center of gravity, payload limits, and arm loading for multi-rotor configurations. Correct balance directly affects flight stability and motor longevity.

Lesson 4 • Component Mounting and Fasteners

Covers torque specifications, thread-locking compounds, and vibration-resistant fastener techniques. Correct fastening prevents component loosening under flight vibration.

Lesson 1 • Maintenance Documentation and Records

Creates compliant maintenance logs, discrepancy records, and return-to-service sign-offs. Accurate records support regulatory audits and liability protection.

Lesson 2 • Structural Repair Techniques

Applies epoxy, carbon fiber patching, and frame replacement to restore structural integrity. Repair decisions balance cost, safety margin, and return-to-service timeline.

Lesson 3 • Pre-Flight and Post-Flight Inspections

Executes standardized checklists for pre-flight airworthiness and post-flight condition assessment. Consistent inspection habits catch developing faults before they cause failures.

Lesson 4 • Maintenance Program Development

Designs interval-based maintenance schedules using flight hours, cycles, and calendar time. A structured program reduces unplanned downtime and extends airframe service life.

Lesson 1 • Electrical and Electronic Fault Isolation

Applies signal tracing, load testing, and component substitution to isolate electrical faults. Builds on earlier electrical skills to handle complex multi-board failures.

Lesson 2 • Systematic Fault Diagnosis Framework

Introduces a structured divide-and-conquer diagnostic methodology for drone systems. A repeatable process reduces diagnostic time and prevents misdiagnosis.

Lesson 3 • Post-Repair Verification and Testing

Validates repairs through bench tests, motor spin tests, and controlled hover evaluations. Verification confirms the fault is resolved before returning the drone to service.

Lesson 4 • Flight Log Analysis

Extracts and interprets black-box flight logs to reconstruct fault sequences. Log analysis reveals intermittent faults invisible during bench testing.
