9imod 55KG Servo
High-voltage 180-degree coreless digital servo selected for steering duty.

This project starts with a Shiroi XL6S Pro Roller and follows the entire TECH1RC build from the bare platform through electronics installation, custom lighting, setup, testing, fixes, and the first real runs.
Current stage
Electronics selected. Installation is next.
From Roller to Runner
The Shiroi arrived as a Pro Roller with no electronics included. That makes it a perfect Test Lab project: every major electronic component can be selected, installed, documented, and tested as part of the build rather than hidden inside an RTR package.
The goal of this page is to grow with the truck. As the build progresses, TECH1RC will add installation notes, setup changes, problems and fixes, running impressions, and future upgrades here.

Planned Electronics
These are the components selected for the build before installation. The list will be updated if the setup changes during testing.
Platform
Team Corally Shiroi XL6S Pro Roller
ESC
Hobbywing EZRUN 8BL150 G2 — 150A
Motor
Hobbywing EZRUN 4274 G2 — 2000KV, 4-pole brushless
Steering
9imod 55KG HV Coreless Digital Servo — 180°
Transmitter
DumboRC X4 — 2.4GHz
Receiver
DumboRC P6F — 6-channel, 4.8–10V DC
Lighting
Custom LED setup — testing stage
Status
Pro Roller — electronics installation pending

Power System
The planned power system pairs a Hobbywing EZRUN 8BL150 G2 150A ESC with an EZRUN 4274 G2 2000KV 4-pole brushless motor. The next milestone is the physical installation and wiring, followed by setup and bench testing.
Supporting Electronics

High-voltage 180-degree coreless digital servo selected for steering duty.

2.4GHz pistol-grip transmitter selected for the Shiroi project.

Six-channel receiver marked for 4.8–10V DC operation.

Next Milestone
The roller, power system, steering servo, and radio gear are all in hand. The next update will document how they fit the Shiroi chassis, how the wiring is routed, and what changes are needed before the first powered test.
Custom LED lighting is also being experimented with separately and will be added to this build log once the final setup is decided.
