Product description
This 1/12 scale brushless RC monster truck brings hobby-grade speed and rugged off-road performance for outdoor play and racing. With a brushless 3800KV motor and metal drivetrain components, this HAIBOXING 903A offers rapid acceleration and improved traction for competitive runs and bashing sessions.
Key Points
The model includes a 2847 brushless motor rated at 3800KV and a 4WD layout that helps deliver a top speed of up to 55 km/h according to the manufacturer. It ships RTR with two 7.4V 1600mAh Li-Po batteries, one installed and one spare in the box, plus USB charging cables. The chassis has a centrally placed motor to improve weight balance and handling, while many drivetrain parts are upgraded to metal for greater durability.

Benefits
The combination of a high-RPM brushless motor and metal drive shafts gives the truck quick throttle response and reliable power delivery on loose or uneven terrain. Aluminum oil-filled shocks and sponge-insert V-tread tires absorb impacts and improve traction, which makes cornering and jumps more controlled. The waterproof ESC helps protect electronics from splashes during off-road use, increasing the number of possible running environments.
Usage Recommendations
Charge both included batteries before first use and follow the manufacturer guidance on battery type to avoid applying a 3S or higher pack. The optional wheelie bar included in the box can reduce tipping during aggressive acceleration and is simple to install if you want more rear stability. Keep spare parts in mind if you plan frequent bashing since many exterior plastics are reinforced but still subject to wear from hard impacts.
