Tamiya Motor Specs & Break-in Strategy Reference
Different motors have different designs, RPMs, and torque characteristics — so break-in strategies should differ too. Quick reference for 8 mainstream Tamiya motors.
Entry-level motors (beginner-friendly)
| Model | Load RPM / Torque | Brush Type | Break-in Strategy |
|---|---|---|---|
| Yellow · Light Dash | 9,800 RPM / 10 g·cm | Copper brush | Low voltage, short stages (1.5V × 5 stages) |
| Purple · Rev Tuned | 14,300 RPM / 10 g·cm | Copper brush | Standard 10-stage |
| Orange · Torque Tuned | 12,000 RPM / 14.5 g·cm | Copper brush | Standard + torque load |
| Gray · Atomic Tuned | 13,700 RPM / 10 g·cm | Copper brush | Standard 10-stage |
Advanced motors (carbon brush, deep break-in capable)
| Model | Load RPM / Torque | Brush Type | Break-in Strategy |
|---|---|---|---|
| Red · Hyper Dash 2 | 17,300 RPM / 10 g·cm | Carbon brush | Full 10-stage (mandatory) |
| Green · Power Dash | 18,100 RPM / 16 g·cm | Carbon brush | Full 10-stage + torque test |
| White · Sprint Dash | 19,500 RPM / 17.5 g·cm | Carbon brush | Progressive ramp, careful temp control |
| Black · Plasma Dash | 23,500 RPM / 13 g·cm | Carbon brush | Slow & careful, 2× cooling time |
Strategy notes
Copper brush motors (yellow, purple, orange, gray): thin and fragile brushes — not suited for high break-in voltage. Start at 0.8V, max 2.0V.
Carbon brush motors (red, green, white, Plasma Dash): can take higher break-in voltage, but Plasma Dash runs hottest — double the cooling time.
Tamiya official competition rules: no opening motor case, no magnet boosting, no altering brush conductor length. Break-in is legal (just optimizing existing contact). Any teardown or physical modification disqualifies.
