The Traction Hobby KM WRC C3 1/7 Rally RC Car is a large-scale, performance-focused rally machine designed for RC enthusiasts who want a combination of realistic motorsport styling, powerful brushless electronics, and an advanced competition-inspired chassis.
Built around a rigid 4mm 7075-T6 CNC aluminum chassis, the KM WRC C3 uses a sophisticated three-differential drivetrain, four-wheel independent suspension, metal drivetrain components, and a remotely selectable RWD / 4WD system. This gives drivers the flexibility to choose rear-wheel-drive characteristics for slides and dynamic handling or four-wheel drive for maximum traction and stability.
Power is supplied by a HobbyWing 4074 brushless motor paired with a HobbyWing WP-8BL100A waterproof ESC, supporting 2S–4S LiPo batteries. Combined with a 20KG metal-gear steering servo and gyro-equipped 10-channel radio system, the WRC C3 delivers the control required for high-speed rally driving and mixed-surface runs.
One of the standout features of the KM WRC C3 is its selectable drivetrain configuration.
Drivers can choose between:
RWD – Rear-Wheel Drive
Provides more dynamic rear-end movement and allows experienced drivers to explore power slides, drifting, and rear-wheel-drive handling.
4WD – Four-Wheel Drive
Sends power through all four wheels for increased traction, improved acceleration, and greater stability on loose or mixed surfaces.
This makes the WRC C3 suitable for different driving styles without requiring major mechanical changes.
Unlike simpler RC platforms, the WRC C3 uses front, center, and rear differentials to manage power distribution throughout the drivetrain.
The three-differential configuration helps provide smoother power delivery and more predictable handling during acceleration, braking, and cornering.
A heavy-duty metal drivetrain supports the high-output brushless power system and includes hardened driveshaft components and CVD-style front universal joints.
The KM WRC C3 comes equipped with a HobbyWing 4074 brushless motor and WP-8BL100A waterproof brushless ESC.
The system supports 2S through 4S LiPo batteries, allowing drivers to select their preferred power level depending on driving conditions and experience.
The adjustable CNC motor mount supports different gearing configurations, allowing further performance tuning.
At the heart of the WRC C3 is a 4mm-thick 7075-T6 CNC-machined aluminum chassis.
This high-strength foundation provides the rigidity needed for a large 1/7 scale RC car while creating a stable mounting platform for the drivetrain, suspension, electronics, and battery.
Additional CNC aluminum components are used throughout the suspension system, including the shock towers and suspension arm mounting areas.
The WRC C3 uses four-wheel independent suspension to provide responsive handling across changing road surfaces.
Large 103.5mm metal oil-filled coilover shocks help absorb bumps and maintain tire contact during aggressive driving.
The suspension can be adjusted to better suit different surfaces, driving styles, and vehicle setups.
In addition to electronic braking through the ESC, the WRC C3 incorporates a servo-controlled mechanical braking system.
A dedicated auxiliary servo operates the system, providing another layer of braking control within the large-scale drivetrain architecture.
The WRC C3 is engineered to handle the torque generated by its brushless power system.
Drivetrain equipment includes:
The motor mount supports 14T–20T pinions, with a 15T hardened steel pinion fitted as standard.
Steering duties are handled by a 20KG digital servo with full-metal gearing.
The high-torque servo provides the steering force required for the large wheels and substantial weight of the 1/7 scale chassis while maintaining responsive directional control.
The included Dumbo 10-channel color-screen transmitter provides control over the vehicle’s primary and auxiliary functions.
An X10FG receiver with integrated gyro stabilization helps improve directional stability, particularly during high-speed driving or when running on loose surfaces.
The large-scale rally body is produced from 1.2mm vacuum-formed polycarbonate, providing a balance between realistic appearance and impact resistance.
Scale-inspired exterior details include:
A separate 1.5mm PC inner fender system helps provide additional protection around the chassis.
Integrated SMD and LED lighting enhances the scale appearance of the vehicle.
The lighting system provides realistic front and rear illumination, making the WRC C3 particularly impressive during evening driving and scale photography.
