The WPL C94 RTR UAZ-469 is one of the most popular WPL platforms because it’s:

-
Capable of major performance upgrades
If you’re wondering which upgrades actually make a difference (and which don’t), this guide breaks it down by priority, not hype.
Stage 1: Must-Have Reliability Upgrades
These upgrades fix the known weak points of the stock C94.
🔧 Metal Upgrade Kit (Highly Recommended)

The stock plastic drivetrain works — until you:
-
Add weight
-
Add torque
-
Drive outdoors regularly
What metal upgrades improve:
-
Adds weight > Lowers the CG > Reduce roll over tendency
-
Axle durability
-
Drivetrain lifespan
Who should install this:
✔ Outdoor drivers
✔ Anyone planning further upgrades
✔ Anyone who hates fixing broken plastic parts
🔧 17g DMG Metal Gear Servo

The stock servo is functional but risk breaking the plastic gears.
A metal gear servo gives:
-
Stronger steering under load
-
Better control on uneven terrain
-
99% less risk of breaking gear during operation
This is one of the highest value upgrades per dollar.
Stage 2: Performance & Driving Experience Upgrades
This is where the C94 starts to feel like a different vehicle.
⚙️ Dual-Speed Gearbox

The dual-speed gearbox adds:
-
Low gear for crawling
-
High gear for trail driving
Instead of compromising between speed and torque, you get both!
Best for:
✔ Trail runs
✔ Mixed terrain
✔ Realistic driving experience
Stage 3: Immersion & Realism Upgrade (Most Popular)
🔊 RES-V3 Sound ESC System
👉 https://www.wpl-rc.com/products/r-e-s-v3
This is the upgrade that changes how the C94 feels, not just how it drives.
What RES-V3 adds:
-
Engine sound synced to throttle
-
Integrated ESC + receiver + sound
-
Brake, idle, and acceleration sound
Most C94 owners say:
“This is the upgrade that made my WPL feel alive.”
