Course Structure:

Lesson 1. Safe EdgeTX Update: Full Guide (Backup & 2 Flashing Methods)

This lesson is dedicated to the fundamental stage of preparing your FPV radio for operation — firmware update. We will cover in detail:

Why Update: We'll explore the advantages of new EdgeTX versions compared to older and stock firmwares.

Safety First: Learn how to create a complete backup of your radio's settings to your computer.

Two Flashing Methods:

Online Method: Fast update via USB using the EdgeTX Buddy online tool.

Offline Method: Reliable update via SD card and BootLoader mode, if the first method doesn't work.

After this lesson, your radio transmitter will be ready for further, more in-depth configurations!

Lesson 2. EdgeTX Radio Stick Calibration

After a firmware update, it is absolutely essential to recalibrate the sticks of your EdgeTX radio transmitter. This lesson explains in detail why this is critical for safe and precise flight.

We will begin with a calibration diagnostic using the "Channels Monitor" to identify any inaccuracies (e.g., incomplete travel to -100/+100 or center offset).

Next, you will learn the correct calibration technique for EdgeTX: how to put your radio into calibration mode, how to move the sticks (not in circular motions!), and what control points to use. Special attention will be paid to applying the correct pressure on the sticks to avoid errors.

At the end of the lesson, we will re-verify the calibration results in the "Channels Monitor" and explore additional verification methods, including corner testing and checking for smooth movement, which is particularly useful when purchasing a used radio transmitter. After this lesson, you will be confident that your sticks are perfectly set up for precise control!

Lesson 3. EdgeTX Model Setup: From Blank Slate to Flight-Ready!

This lesson is a step-by-step guide on setting up a new drone model on your radio from scratch.

Instead of flying on default settings, you will learn to create a separate profile for each of your drones. This will allow you to fully master your radio.

From this lesson, you will learn how to:

Create a new model and give it a name (e.g., "Nazqul").

Configure timers – the most useful function for monitoring flight time. You'll be able to see how long the drone was in the air (for example, by linking the timer to the ARM switch).

Properly set up (or disable) trims, so accidental bumps don't mess up your settings and the drone flies straight.

Set up pre-flight safety checks – the radio will warn you if you turn it on with the throttle up or the ARM switch active.

Configure the radio module – choose the correct communication protocol (like CRSF for ELRS) or turn it off if you're flying in a simulator.

Lesson 4. RF Module Configuration (Internal & External)

This lesson explains how the "heart" of the radio's communication works – the Internal RF and External RF radio modules.

It reveals what the key technical parameters mean and how they directly impact flights.

The lesson explains:

Baud Rate: What this is and why a high speed (e.g., 1.87M) gives you low latency, which is critical for fast reactions.

Packet Rate: It explains why racers choose a high frequency (e.g., 1000Hz) for maximum smoothness, while long-range pilots choose a low frequency (50Hz) to increase communication range.

The difference between modules: It clarifies why an external module is needed (e.g., to use a different protocol than the one built into the radio) and what limitations (e.g., 400k Baud Rate) it might have.

The purpose of other settings: It describes what "Channel Range" is and how the "Receiver Number" helps avoid confusion between different drones.

Lesson 5. Trainer Mode in EdgeTX: Training and Joint Control

This lesson explains in detail how to set up Trainer mode. This is a key feature that allows an instructor to safely teach a new pilot.

From this lesson, you will learn:

The "Master/Slave" concept: How the link works, where "Master" is the instructor's radio (connected to the drone), and "Slave" is the student's radio.

Connecting via cable: How to physically connect the two radios using a cable in the dedicated "Trainer port" (using Master / Jack and Slave / Jack modes).

Setting up the switch: How to assign a special toggle switch on the instructor's radio.

The training process: How the instructor can use this switch to instantly transfer control to the student and just as instantly take it back in any critical situation.

This allows training to be conducted effectively and safely, as the instructor can always intervene and prevent the model from crashing.

Lesson 6. Flight Modes in EdgeTX – Configuration for FPV Drones

Is your drone suddenly drifting to the side? You might have accidentally bumped your trims! In this video, we dive into the "FLIGHT MODES" section.

Although this feature was originally designed for airplanes, it holds an incredibly useful option for FPV drone pilots (especially those flying with goggles). Instead of setting up modes, we're going to do what most pilots do—completely disable the trims!

I'll show you how to do it correctly:

Why using trims is a "quest" for FPV.

How to physically set your trims to the center position.

How to deactivate them in the FM0 menu so they never get accidentally knocked out of alignment during flight.

It's a simple setup that will save your nerves and prevent mysterious drifting!

Lesson 7. EdgeTX Inputs Configuration

In this lesson, we delve into the "Inputs" section of your EdgeTX radio transmitter, where you assign and configure all physical control elements – sticks, switches, buttons, and sliders.

You will learn:

Assigning Physical Controls: How to link each movement on your radio to a software input.

Key Input Parameters: We'll examine in detail Source, Weight (Rates), Offset, and various Curve types (Expo, Diff, Custom), allowing you to fine-tune sensitivity and control response.

Rates and Expo: We'll demonstrate how to decrease or increase stick sensitivity to make control smoother for precise maneuvers or more aggressive for freestyle, as well as how to maintain high sensitivity at the stick's travel limits.

Advanced Capabilities: Using Mode and Switch to activate inputs only in specific flight modes or via switches.

Practical Configuration: A step-by-step guide on how to assign all your switches, buttons, and sliders to input channels, creating up to 12 control channels for your drone.

This lesson will help you gain complete control over your FPV drone, configuring each input exactly as you need it!

Lesson 8. Mixes Configuration – Final Stage of Channel Setup

This lesson uncovers the essence of the "Mixes" section in EdgeTX. This is a critically important stage where we "activate" all previously configured inputs and prepare them for transmission to the drone. Without proper setup in this menu, your switches, buttons, and sliders simply will not work.

In this lesson, we will cover:

The Key Role of "Mixes": Understand why this menu is a mandatory step after "Inputs" and how it "brings your switches to life."

Core Parameters: We'll review familiar settings such as Source, Weight, Offset, and Curve, clarifying their specific roles at this stage.

Unique "Mixes" Functions: Learn about specific parameters like Trim, Multiplex (Add, Multiply, Replace), and Warning, which differentiate this menu from "Inputs."

Advanced Capabilities: Briefly examine advanced functions such as Delay and Slow, explaining why they are rarely used for FPV drones.

Verifying Results: Learn how to use the "Mixers Monitor" to ensure all channels are configured correctly and are operating as expected.

After this lesson, you will confidently navigate the logic of "Mixes," allowing you to finalize the setup of all channels and prepare your radio transmitter for signal output to the drone.

Lesson 9. Final Channel Configuration (Outputs) in EdgeTX

In this lesson, we'll break down the "OUTPUTS" page – the final and most important stage of your radio setup!

This is where the fine-tuning of every channel happens. You will learn:
