Tamiya 15307 Ultra Dash Motor - Mini 4WD Speed Upgrade  [15307]

What the Tamiya 15307 Mini 4WD Ultra Dash Motor offers

The Tamiya 15307 Mini 4WD Ultra Dash Motor is a high speed option for enthusiasts focused on lap times. It combines elevated RPM with usable torque, making it a go-to choice for short circuits and speed-focused tuning.

Voltage window and gearing advice

This motor runs best between 2.4-3.0V and can reach roughly 24,000 to 27,500 RPM under the suggested torque load of 1.4-1.9 N.m. Pair it with the 8T Metal & Plastic Pinion Gear Set (Item: 15289) to improve gear meshing and to avoid heat concentration that could deform lightweight chassis parts.

Routine care and safe handling

Apply grease to the gear teeth and shaft receiver routinely to maintain smooth operation. Avoid forcing wheel rotation, expect the motor to become hot after use, and remove batteries when not running to reduce wear on contacts.

Best use scenarios on the track

This Ultra Dash Motor excels in competitive environments where top speed is decisive. For consistent results, many racers use Ni-Cd battery packs and keep a maintenance schedule to preserve motor performance.
