The Tamiya 15307 Mini 4WD Ultra Dash Motor is built for hobbyists who want a noticeable speed boost in their Mini 4WD cars. Its high RPM and strong torque suit timed runs and sprint-style track layouts where top speed matters.
This motor performs within a 2.4-3.0V range and produces roughly 24,000 to 27,500 RPM at a recommended torque load of 1.4-1.9 N.m. Use a metal pinion from the 8T Metal & Plastic Pinion Gear Set (Item: 15289) to ensure reliable power transfer and to reduce the risk of heat-related chassis warping.
To keep performance consistent, apply grease to the gears and the shaft receiving area on a regular schedule. Do not jam the wheels or force rotation, and be aware the motor gets very hot after runs. Remove batteries after use to avoid drain and unnecessary stress on contacts.
The Ultra Dash Motor is aimed at competitive track use where sustained top speed is needed. Ni-Cd batteries are commonly recommended for best results, and correct gearing plus routine maintenance will help maximize motor life.
