Wrenching. Stretching. Crawling.

TRX‑4 stretch mod + full Wraith electronics rebuild. More power, more control, more trail fun.

Wraith & Stretch | TRX‑4 Traxx Upgrades + Full Wraith Electronics Rebuild!

In this episode, I dive into two awesome projects: giving my Traxxas TRX‑4 Sport with Traxx some much‑needed *Portal Bling*, and completely overhauling the electronics in my Axial Wraith 1.9 RTR — a rig I scored for a killer deal at my local hobby shop.

TRX‑4 Sport w/ Traxx Upgrades
The TRX‑4 gets a couple of key improvements to boost durability and trail performance:
*Aluminum Portal Covers (aka Portal Bling!)* installed front and rear
Full cleanup and inspection of portal gears and bearings
A simple but effective *5mm rear link stretch* to keep the Traxx from rubbing the body during articulation

These upgrades help the TRX‑4 run smoother, stay protected, and handle the Traxx setup with ease.

Axial Wraith 1.9 — Complete Electronics Rebuild
This Wraith came home with me for a great price, but the electronics needed a full reset. So I tore everything out and rebuilt it from the ground up with a fresh, powerful setup:

New Electronics Installed
Reefs RC 422HD v2 Steering Servo
Reefs RC 8.4V EZ‑BEC** powering the servo for maximum torque
Vanquish Aluminum SCX10 Original 3‑Gear Transmission with gear guard
Spektrum RC 2‑in‑1 2300kv Motor/ESC Combo**
Tons of power on tap
Surprisingly smooth low‑speed control for technical crawling

Radio System Upgrade
To tie everything together, the Wraith is now running:
*Spektrum RC iXSR Android‑based Transmitter*
*Spektrum SPMSR400T 4‑Channel Receiver*

This combo gives the Wraith a modern, responsive feel with plenty of tuning options.

Upgrades, caffeine, and questionable decisions — the perfect recipe for RC greatness
