Stretching the UDiRC UCX 2405 Pro: Longer + More Stable (Full Mod Guide)

In this video I show how I extended the 1/24 scale UDIRC UCX 2405 Pro and make it more stable with a mix of TRX4M, FCX18, SCX24 parts. I’m no crawler expert, but I’ll walk you through exactly what parts WORKED!

⚙️ Mods covered:
- Links to make it longer
- Driveshafts
- Shocks
- Injora Wheels and Tyres
- Ramp Crab servos

💡 Key takeaways:
- Extending the rear gives the better stability.
- Stock ESC struggles with high‑torque servos — Ramp Crab worked best
- Stainless body raises centre of gravity, but mods help reduce tip‑overs
- It’s all about experimenting, sourcing parts, and having fun with small‑scale RC

👉 Stick around for the running footage at the end!

👉 Share your own UCX 2405 Pro mods in the comments — would you extend just the rear, or go full front + rear?
