Tamiya 15489 GP.489 Atomic Tune 2 Motor PRO - Product Summary

The Tamiya 15489 Atomic Tune 2 Motor PRO is built for Mini 4WD PRO fans who want to tune handling and pace. It suits racers aiming to balance acceleration and top end on circuits with mixed straights and technical turns, offering a practical upgrade path for race days.

Build Details and Model Fit

Constructed with efficient metal brushes, this motor performs reliably across common track surfaces. It runs on 2.4-3.0V input and is intended exclusively for Mini 4WD PRO chassis, so fitment is limited to that series. The design lets racers fine-tune balance between low end pull and midrange speed.

Torque and Speed Performance

On recommended load the Atomic Tune 2 Motor PRO produces torque around 1.6-1.8mN-m and turns between roughly 12,300 and 14,500 RPM. That trade off gives consistent drive out of corners while maintaining competitive straightline pace. The motor also features a black end bell for durability and a clean look.

Installation Notes

Pinion gears are supplied separately, allowing users to select ratios that match their setup and track plan. This makes the motor a sensible option for those stepping into tuning, offering room to experiment without overwhelming complexity.
