Inspection and Identification
We compared two DATX models to determine which switches were considered standard and which were non-standard. The non-standard switches were marked for removal.
Disassembly
The back of the DATX was removed by unscrewing six small screws. Both sides of the transmitter were then carefully separated while paying close attention to the internal ribbon cable, which is very delicate and easily damaged.
Switch Removal
We located the four non-standard switches and one button that needed to be removed. Each was unscrewed by loosening the washer securing it in place.
Securing Loose Components
After removing the switches, we hot-glued them onto the inside plastic frame of the DATX. This prevented rattling while ensuring that the glued components did not interfere with the joysticks, internal movement, or electrical paths. We were careful to ensure that no metal parts made contact with other metal surfaces to avoid short circuits.
Reassembly
Once all parts were secure, the two halves of the DATX were reattached—again being careful with the ribbon—and the six screws were reinstalled to close the unit.
Accessing EdgeTX Buddy
We followed the instructions from the EdgeTX User Manual and navigated to EdgeTX Buddy on the computer.
Downloading and Preparing Software
The new firmware was downloaded to the computer to prepare for flashing.
Connecting the Radio
The radio was turned off, then connected to the computer via USB.
Flashing the Firmware
Once the radio was detected, the flashing process was started in EdgeTX Buddy. The software updated the firmware automatically.
Verification
After flashing was complete, the radio was unplugged and powered on. A message displaying “No SD Card” confirmed the installation was successful and that the system was ready for further configuration.
The removal and re-securing of switches reduced internal rattling and improved stability.Careful attention to the ribbon cable prevented damage during reassembly.The updated EdgeTX firmware improved the system’s performance and interface readiness for future missions.
Lab 7: DATX Setup and Modification
Objective
The purpose of this lab was to modify both the hardware and software of the DATX transmitter to meet specific operational requirements. This included removing non-standard switches, securing internal components, and updating the radio’s software using EdgeTX Buddy.
Hardware Modification
Overview
Our subgroup (Kenzie, Bella, and Diego) focused on the hardware modifications of the DATX 6 transmitter. The goal was to identify which switches were non-standard and remove them while retaining the standard ones to ensure proper function and ergonomics.
Steps
Software Modification
Overview
The second half of the lab focused on updating the DATX radio’s software to the latest version of EdgeTX using EdgeTX Buddy. Niko and Clayton led this portion of the lab.
Steps
Results and Observations
The DATX transmitter was successfully modified both mechanically and electronically.
Conclusion
This lab provided hands-on experience in both hardware disassembly and software flashing of UAS ground control transmitters. By physically modifying the DATX and updating its firmware, our group gained a deeper understanding of internal component layouts, switch configuration, and firmware management—skills directly applicable to future UAS integration and maintenance projects.
