Yikong 1/10 YK4107 Tank Turn 4WD Scaler Crawler RTR - Brushed (Available in Dark Blue, Sky Blue, Gold)

Advanced LCG Chassis & Innovative Tank-Turn Trail Performance

Conquer technical rock sections and demanding backcountry trails with the Yikong 1/10 YK4107 Tank Turn 4WD Brushed Crawler. Engineered on an optimized low center of gravity (LCG) chassis, this high-performance trail rig balances premium mechanical features with scale realism at an incredibly competitive value. Outfitted with a classic scale SUV body featuring clear windows and a molded interior cabin, it delivers smooth low-end torque and exceptional trail capability right out of the box.

The standout mechanical breakthrough of the YK4107 is its unique transmitter-activated "Tank Turn" DIG function. By engaging the Channel 4 button on the fly, the system instantly frees the center drive and locks a rear wheel to act as a pivoting anchor point. This allows the vehicle to make micro-radius U-turns on tight cliffs, navigate narrow rocky switchbacks, and escape tricky dead-ends that trap conventional 1/10 scale crawlers.

Heavy-Duty Portal Axles & 2-Speed Transmission

Maximize your trail clearance with front and rear portal axles that raise the axle centerlines to provide a massive 65mm of ground clearance, easily scaling high rocks and roots. The YK4107 is equipped with remote-locking front and rear differentials and a selectable 2-speed transmission controlled directly from your radio. Drop into low gear for massive reduction crawling torque, or shift into high gear on the fly to accelerate along open dirt paths.

Locked-In Brushed Torque & 10-Channel Control

Powering this trail machine is a high-torque 550 size brushed crawler motor paired with a water-resistant 60A electronic speed controller (ESC) that provides precise throttle resolution at ultra-low speeds. Steering authority is managed by a heavy-duty 25KG digital metal-geared steering servo outfitted with an integrated buffer protection system. A professional-grade 2.4GHz 10-channel transmitter controls the entire machine, delivering extensive adjustment profiles, multi-mode LED lighting, and exceptional range up to 400 meters.

Note: This high-performance scale crawler requires a 2S or 3S hardcase LiPo battery pack with an XT60 connector, plus a compatible balance charger and four AA transmitter batteries. All are sold separately.
