Tamiya 15489 GP.489 Atomic Tune 2 Motor PRO - Performance Brief

The Tamiya 15489 Atomic Tune 2 Motor PRO is aimed at Mini 4WD PRO racers seeking a dependable upgrade that blends pull and speed. It is a straightforward choice for club racers who adjust setups to match different circuits and race rules.

Features and Fitment

Equipped with metal brushes for efficient contact and steady output, this motor runs on 2.4-3.0V input and is designed only for Mini 4WD PRO models. Its construction supports regular tuning work and straightforward swaps between race cars of the same series.

Speed and Torque Figures

Under recommended load the motor delivers torque in the 1.6-1.8mN-m range and rotates between approximately 12,300 and 14,500 RPM. That setup helps maintain acceleration out of bends while keeping competitive speed on longer straights. The black end bell also adds robustness to repeated use.

Tuning and Upgrades

Pinion gears are not included so racers choose gear ratios to suit track layout and driving style. This modular approach supports step-by-step upgrades, letting teams optimise acceleration or top speed without replacing the motor.
