YIKONG YK4102 PRO 1/10 Scale 4WD RC Rock Crawler with Remote Differential Locks 2 Speed Transmission and LED Lights
The YIKONG YK4102 PRO is a 1/10 scale 4WD RC rock crawler for trail driving and technical off-road routes. It combines a waterproof 550 brushed motor and Hobbywing 1060 ESC with remotely operated front and rear differential locks, a selectable two-speed transmission and portal axles. A detailed PC body, factory-installed lighting and a 6-channel 2.4GHz radio complete its installed electronics package. Battery and charger selection is shown separately in the existing product options.
Key Features
Remote Front and Rear Differential Locks
Operate the front and rear differential locks from the radio system to adapt traction for changing trail conditions. Independent control helps the crawler maintain drive when a wheel loses grip.
Two-Speed Transmission
Select high or low gear from the transmitter. Low gear supports controlled crawling, while high gear is suited to faster trail driving.
Portal Axles and Trail Clearance
The portal axle layout and listed 5.5 cm ground clearance help the chassis travel over rocks and uneven surfaces. The BOMETOYS listing specifies a 63° approach angle, 47° departure angle and 56° breakover angle.
Waterproof Brushed Power System
A 550 brushed motor and waterproof Hobbywing 1060 ESC power the crawler. The waterproof steering servo and sealed receiver box are designed for off-road use; follow the manufacturer’s care guidance after wet-weather driving.
CNC Aluminum Chassis
The 5 mm CNC aluminum chassis beam and metal drivetrain components provide a solid platform for technical trail use. A dual-sleeve clutch system helps reduce drivetrain load.
Factory Lighting and Scale Details
The factory lighting setup includes headlights, daytime running lights, steering-linked lights, hood spotlights, a roof light bar and taillights. The detailed body features a roof rack, side ladders, tow hooks and other scale accessories.
Magnetic Tilt Body
The magnetic tilt-style body mount provides convenient access to the chassis and battery compartment.
