Tamiya 15455 JR Light-Dash Motor - compact Mini 4WD power unit  [15455]

Product brief for the Tamiya 15455 JR Light-Dash Motor

The Tamiya 15455 JR Light-Dash Motor is a targeted upgrade for Mini 4WD machines that need dependable, efficient drive. The metal brush layout is chosen for durability and lower internal losses compared with some entry level motors.

Standout points

• Durability: Metal brush architecture reduces wear rates and maintains steady output over time.
• Efficiency gains: Lower power loss helps maintain stronger run times from the battery pack.
• Yellow endbell: Distinctive endbell colour aids quick identification during builds and at race days.

Where it fits

Made for Mini 4WD and Dangun Racer use, the motor suits a broad range of chassis formats. It should be used within a 2.4-3.0V window for predictable behaviour in competitive setups.

Adjustment and rpm info

The motor runs in the 14,600-17,800 rpm region, giving room to adjust gearing and weight placement. Follow the suggested torque load of 1.3-1.9 mN.m to keep a stable balance between punch and control.
