The Tamiya Sprint-Dash Motor (Item 15318) is a high-speed motor designed for single-shaft Mini 4WD cars that prioritize maximum top speed on tracks with long straight sections. It is a speed-focused motor with a moderate torque output.
Performance and Specifications
The Sprint-Dash motor is known for its high revolutions per minute (RPM) and is best utilized with specific car setups to maximize its potential.
Features and Usage
- Design: It features a distinctive gray endbell cap and uses durable carbon brushes, which help reduce electrical interference and provide excellent endurance for prolonged use.
- Optimal Course Types: This motor excels on high-speed circuits that feature long straights, where sustained velocity is crucial for winning. It is less suited for highly technical tracks with many turns and slopes, where a higher-torque motor like the Power-Dash would perform better.
- Recommended Setup: Due to its focus on speed over torque, Tamiya recommends using it with small-diameter wheels and a high gear ratio set to achieve optimal performance.
- Chassis Compatibility: It is compatible with a wide range of Tamiya Mini 4WD chassis, including the AR, VS, VZ, Super-II, and FM-A chassis. Note that it is a single-shaft motor, not for use in double-shaft (PRO) chassis like the MS or MA unless specified for a single-shaft setup.
- Competition Status: The Sprint-Dash motor is generally a competition-grade, "Specially Tuned" part that may be banned in some official Tamiya races, but is widely used in Open Class and B-Max competitions.
