Thank you for your continued interest in the latest development progress of the 1/24 scale MACE Monster Truck. Following the assembly and rigorous field testing of the first batch of T0 trial-mold samples, our engineering team identified several details requiring fine-tuning. Driven by our strict demands for performance and vehicle durability, we have implemented multiple significant upgrades to the chassis geometry, drivetrain clearance issues, and powertrain.
Below are the core engineering improvements we have made as we move toward mass production:
1. Resolving Clearance Issues and Reshaping Chassis Details
During initial assembly, we noticed slight interference between the original motor layout and certain chassis structures. To create the perfect mounting space for the motor, we made the following precise modifications to the molds:
Chassis Tub Adjustment: We removed the honeycomb structural reinforcement on the motor mounting side of the chassis, optimizing the space while minimizing any impact on overall rigidity.
Driveshaft Cover Optimization: The side of the center driveshaft cover closest to the motor has been reprofiled into a smooth, curved surface.
Hole Realignment: We realigned the mounting holes on the center reduction gear cover to ensure perfect concentricity of the drivetrain.
2. Eliminating Steering System Binding
Extremely smooth steering action is critical for micro RCs. When testing the suspension travel and steering angles, we noticed that the steering post rubbed against the differential case. To address this, we reduced material and flattened the contact surface on the steering post. This modification completely eliminates the binding points, restoring the precise steering feel that the MACE should have.
3. Powertrain and Top Speed Upgrades
Under the previous powertrain configuration, the test prototype reached a top speed of approximately 20 KM/h. While this is a respectable figure at this micro scale, we know that hobbyists crave more power. To increase punch and top-end performance, we have comprehensively upgraded the power unit: we swapped in a larger 15T pinion gear and upgraded to a 180-size motor. This upgrade will significantly improve the vehicle's straight-line top speed and throttle response.
4. Tightening Tolerances and Eliminating Slop
Slop is the biggest enemy of handling quality. During dynamic road testing, we strictly inspected every moving joint on the entire vehicle. The engineering team has now implemented mold-level corrections to eliminate excess play in the suspension and drivetrain systems. This means that when driving the MACE, hobbyists will experience a much tighter, more direct, and highly responsive handling feel.
Next Steps
The testing and modification of these T0 trial-mold samples represent a crucial step toward perfecting the MACE monster truck. Production of the modified molds is currently underway. We will continue to conduct rigorous bench and field testing to ensure that every mass-produced vehicle meets the highest quality standards.
