LAB 10- Parameters and Build Guide

Overview

In this lab, we worked with the key avionics components used in the Believer aircraft platform. The primary focus involved connecting, configuring, and validating the transmitter/receiver system, uploading compatible firmware and parameters to the flight controller, and verifying complete system functionality through Ground Control.

Assignment: DATX System Setup

Transmitter and Receiver Overview

To connect to an aircraft, a transmitter and receiver must be paired and configured. In this lab, the controller acts as the user interface while the TBS Tracer Micro Starter Set functions as the active transmitter module.

Procedure

Obtain the Starter Set and verify all components.

Solder the required parts.

Insert the provided SD card into the DATX. The card should contain models labeled model00 through model06. Missing files indicate an issue and require instructor assistance.

Flash the transmitter to firmware version 6.17 using the TBS Agent Web.

Open the “Tracer Micro TX” information page and confirm the presence of a User ID.

Use Diff Checker to compare model00 and model01.

LUA Script Questions

What is a LUA script? LUA is a lightweight programming language used to create simple automated functions for various systems.

Why are we using it in this lab? LUA is used to simplify control and automation tasks for the Believer platform during the binding and configuration process.

TX/RX Binding

Connect the receiver to the BlueCube and power on the DATX. Run the LUA binding script and ensure both TX and RX are in bind mode. Confirm successful pairing before proceeding.

⁠

FCU and Parameters

During a previous lab, the BlueCube was flashed to FCU Version 1.31. Because the Windracers parameters that the Ultra uses are on version 1.27 we have to flash the Cube with the older version for the parameters to be the same and to have a true simulated flight experience with the Believe

Firmware and Parameter Upload Steps

Flash the flight controller to the required FCU version.

Connect the controller to Ground Control and open the Parameters tab.

Download the current parameters.

Export the file as parameters_PUB## (group number).

Import and upload the provided file:

Reboot the autopilot using the Engineering window.

Export the updated parameters again and save as parameters_PUB##.

Update the version control table.

⁠

System Connectivity Test

Connect the GPS, airspeed sensor, telemetry module, and DATX.

Verify that all sensors show green status indicators.

Confirm GPS lock and RC connection in the Ground Control interface.

Take a screenshot of the Platform Health Status and RC status.

Current FCU Version: Originally 1.31, reverted to 1.27 for parameter compatibility.

Servos, ESC, and Motors

Using the DAB010 model as a reference, a complete wiring table was created. This includes all telemetry components, sensor connections, control surfaces, and propulsion wiring. The notes compiled from the sample platform will serve as the reference for all remaining assembly and integration work.
