Lab 07: DATX Controller Modification and Configuration


Overview


In this lab, our group modified and configured the DATX controller to align with Windracers’ operational standards. The goal was to eliminate unnecessary switches and migrate from OpenTX to EdgeTX 2.7.1 to improve safety and simplify flight operations. Working in our Believer groups, tasks were split between hardware modification and software configuration.
⁠

Group Info

Group Number: 5
Role: Software Team
Controllers Modified: DATX #2 and DATX #5
⁠

Software Configuration Process


Our software team was responsible for migrating the Taranis controller firmware from OpenTX to EdgeTX 2.7.1.
We followed the
EdgeTX Update Guide
⁠
to ensure a clean and reliable flash.
​Steps Taken
Backed up all existing OpenTX models and settings.
Downloaded the correct EdgeTX firmware (version 2.7.1).
Connected the controller via USB and entered bootloader mode.
Used EdgeTX Companion to flash the firmware onto the controller.
Verified firmware version and defaulted settings to match Windracers’ layout.

​DATX Modifications
DATX #2: Flashed with EdgeTX 2.7.1
DATX #5: Modified the controller switches to match that of the Windracer Ultra

Hardware Team Process (Partner Team)

The hardware team disassembled and modified the Taranis controllers to match the Windracers configuration.
Their main goals were to remove or disable unused switches and reassemble the controller safely.
Steps Taken
Identified non-standard switches.
Disassembled the controller shell carefully.
Removed unneeded switches and hot-glued them inside the housing.
Reassembled the controller with all standard switches accessible.
Conducted a post-modification inspection for loose wiring or solder points.

Importance of Each Team’s Task

Software Team: Ensured firmware compatibility, flight stability, and safe radio-aircraft communication.
Hardware Team: Prevented accidental switch activation, simplified control layout, and maintained physical safety.
Both tasks were critical hardware modifications ensured operational safety, while software configuration enabled reliable aircraft communication and standardized operation across controllers.
⁠

Reflection

This lab highlighted the importance of effective teamwork between hardware and software groups.
Both teams depended on each other’s success, hardware modifications allowed safe handling, while software ensured seamless integration with the receiver system. Clear communication within Group 5 helped us complete both modifications and firmware installations efficiently.
