The Tamiya Power-Dash Motor (Item 15317) is a high-performance, single-shaft motor for Mini 4WD cars, specifically designed to provide high torque and acceleration, making it an excellent choice for technical tracks with many slopes and elevation changes.
Key Features and Specifications
The Power-Dash motor prioritizes "punch" (low-end power) over outright top speed, offering a versatile performance balance ideal for challenging circuits.
- Performance: It delivers excellent acceleration and robust power through climbs and complex track features, helping the car maintain speed when the circuit demands grunt rather than maximum RPM.
- Durability: The motor is equipped with durable carbon brushes, which ensure a longer life span and more consistent performance than motors with older bronze brushes.
- Aesthetics: It is easily identifiable by its distinct dark green endbell cap and silver metallic housing.
- Competition Status: This motor is typically legal for use in official Tamiya races, including "Stock" and "Modified" classes, as it falls within the permitted performance range.

Compatibility and Setup
- Chassis Compatibility: The Power-Dash motor is designed for single-shaft chassis, and is compatible with a wide range of Tamiya Mini 4WD platforms, including the AR, VS, VZ, Super-II, and FM-A series. It is not intended for use with the double-shaft PRO series chassis (MS, MA).
- Optimal Gearing: To best exploit the motor's high torque, Tamiya recommends pairing it with large-diameter wheels and a lower gear ratio, such as a 3.7:1 gear set, to achieve a balanced and powerful performance on technical tracks.
