YIKONG YK4107
For RC crawling enthusiasts, YIKONG’s YK4107 series is undoubtedly a strong contender. But what are the real differences between the standard YIKONG YK4107 and the upgraded YIKONG YK4107 Pro? This review breaks it down from a technical perspective.
Motor & Power System
The biggest distinction lies in their power systems:
- YIKONG YK4107 comes equipped with a classic 550 brushed motor, known for its strong torque and reliability in climbing and off-road scenarios.
Note: The transparent acrylic yikong yk4107 remote control car shown in the picture is not for sale.
- YIKONG YK4107 Pro, on the other hand, is upgraded to a 2100KV brushless motor, offering faster throttle response, higher efficiency, and significantly longer lifespan—ideal for users seeking top-tier performance.
Servo & Control System
Both models are fitted with a 25KG high-torque metal gear steering servo, now paired with a new servo buffer protection system for increased durability. The maximum steering angle reaches 40°, ensuring agile handling even in tight terrain.
Chassis & Suspension System
The YIKONG YK4107 and Pro share YIKONG’s new 2025 LCG (Low Center of Gravity) chassis, which enhances stability on inclines. Both are equipped with full-metal hydraulic shock absorbers and portal axles front and rear, with 65mm of ground clearance, effectively reducing torque twist and maximizing terrain adaptability.
Unique Features
One standout feature is the tank-turn function, which can be activated by pressing Channel 4 on the transmitter. This unlocks the rear differential automatically, enabling the vehicle to pivot in place—extremely useful in narrow or tricky terrain.
Transmission & Differential Locking System
- Remote-controlled front and rear differential locks
- 2-speed transmission (High/Low)
These features improve adaptability across a wide range of surfaces and driving styles.
Appearance & Body Design
Both models use a 1.2mm polycarbonate (PC) body with transparent windows, complete with a detailed simulated interior.
- YK4107 offers three color options: Hydro Blue, Slate Gray, and Dark Blue.
- YK4107 Pro is available in a distinctive Green color.
- Both models adopt a magnetic body mounting system, enhancing realism and ease of use, making body swaps and daily maintenance more convenient.
Conclusion
- If you want smoother power delivery, less maintenance, and longer lifespan, the YIKONG YK4107 Pro is the better choice.
- If you’re on a tighter budget but still want a rich set of crawling features, the YIKONG YK4107 will not disappoint.
