YIKONG YK4073 Trailbreaker TB7 Desert Baja Bronco 1/7 RC Car 2.4GHz 4WD 6S Crawler Climbing Car Toys

The YIKONG YK4073 Trailbreaker TB7 is a 1/7 scale 4WD brushless desert truck built for high-speed off-road driving. It combines a 4274 1600KV brushless motor, HobbyWing MAX8 150A ESC, gyro-equipped 5-channel radio, three metal-gear differentials and eight long-travel oil-filled shocks. Its reinforced aluminum chassis and PC body are designed for runs over sand, gravel and rough terrain.

Key Features

Brushless Power with 3S to 6S ESC Support

The HobbyWing 4274 1600KV motor is paired with a waterproof MAX8 150A ESC that supports 3S to 6S LiPo batteries. BOMETOYS lists speeds of 95+ km/h; actual speed depends on battery setup, gearing and driving surface.

Reinforced Three-Layer Aluminum Chassis

The aluminum main chassis, upper deck and reinforcement plates form a rigid structure. CNC-machined drivetrain components include front, center and rear metal-gear differentials and a 63T steel spur gear.

Eight Long-Travel Oil-Filled Shocks

Eight aluminum shocks with progressive springs help the suspension manage rough ground and maintain control over uneven terrain.

4WD Desert Truck Drivetrain

The YK4073 combines independent front suspension with a rear solid axle and differential. A steel front CVD driveshaft and 17 mm wheel hexes complete the off-road setup.

Gyro-Equipped Radio and LED Lights

The 2.4 GHz 5-channel transmitter includes an integrated 3-axis gyro. The truck also features front bumper and roof-mounted lights, plus a painted PC body secured to the roll cage.

Frequently Asked Questions:

Does the YK4073 support 6S batteries?

Yes. The listed MAX8 150A ESC supports 3S to 6S LiPo batteries. The optional battery bundle contains one 3S battery, so a 6S setup requires a separately sourced compatible battery configuration.

What does the built-in gyro do?

The integrated 3-axis gyro helps support directional stability during driving. Its effect depends on the surface, speed and gyro setting.

Can I change the gearing?

The listed compatible 11T, 12T and 13T pinion options use different gear ratios. Gearing affects the balance between acceleration and top speed.

Is the battery and charger included?

Only when the Inclusion option is selected. That option corresponds to the listed 3S battery and 80W charger. Four AA transmitter batteries are not included.

Does BOMETOYS support replacement parts?

Yes. BOMETOYS supports a full range of replacement parts. Send us a clear photo of the YK4073 part and its part number, and we will help match the correct replacement.
