As a star model in the YIKONG lineup, the YK4073 boasts a unique design and performance that rivals real racing machines.

1. Striking Appearance and Robust Structure

Measuring 640mm in length, 379mm in width, and 265mm in height, with a weight of 5.9 kg, the YK4073 commands attention with its imposing presence. Whether in dynamic red or sophisticated blue, this car’s bold aesthetics leave a lasting impression. The body, made from impact-resistant, one-piece PC material, is secured to a robust roll cage at multiple points, enhancing durability and providing added protection during rollovers.

The chassis features a newly designed aluminum main frame and upper deck with a three-layer construction, giving the vehicle a lower center of gravity and exceptional handling. Even in high-intensity driving conditions, the car maintains excellent stability and traction.

2. Electronic Configuration: The Pinnacle of Power and Control

Powering this “beast” is a 4274 1600KV brushless motor paired with a Hobbywing MAX 8 150A/950A waterproof electronic speed controller (ESC), which supports 3S to 6S lithium batteries. Whether it’s blazing through a track or tackling rough off-road terrain, the YK4073 performs seamlessly. This setup provides unparalleled speed and power, enough to make any driver’s adrenaline spike.

The remote control features a 5-channel transmitter equipped with a built-in gyroscope for enhanced stability, ensuring precise steering even at high speeds. The 30KG metal gear servo further improves the car’s responsiveness and durability, maintaining accuracy during intense maneuvers.

3. Suspension and Shock Absorption: Stability You Can Rely On

One of the highlights of the YK4073 is its suspension system. The front independent suspension combined with a solid rear axle and differential delivers exceptional handling. With eight ultra-long aluminum shock absorbers featuring progressive springs on both the front and rear, the car absorbs impacts effortlessly and stays stable on rough terrains. This design ensures superior flexibility and resilience, whether jumping ramps or making sharp turns.

The driveshaft, made from heavy-duty steel, complements the CNC-machined aluminum center differential case and high-strength 63T steel gear, ensuring durability and stability under high loads. For players, this level of metal components guarantees long-term use and easy maintenance.

4. Driving and Handling: A Thrilling Off-Road Experience

For off-road enthusiasts, the driving experience of the YK4073 is pure joy. The car features 17mm hex wheel hubs and realistic racing tires that offer excellent traction on sand, dirt, grass, and various terrains. The gear ratio of 1:14.6 ensures stability at high speeds while also delivering torque for low-speed crawling.

The newly designed suspension system and central differential work together to maintain perfect vehicle posture during high-speed turns, preventing rollovers. Players can confidently execute complex driving techniques without worrying about losing control.
