Racing Mini-Z PNWC 70 Turn Ball Bearing Motor

The Hobby Hideaway Verdict: Precision Power for the Competitive Edge! When you’re looking to squeeze every ounce of performance out of your 1/28th scale chassis, the motor is where it starts. PN Racing has redesigned this 130-size motor from the ground up to address the two biggest enemies of micro racing: heat and friction. By integrating genuine Japanese ball bearings and a strategic air-cooling scoop, this motor stays cooler and spins more freely than standard bushing motors. Whether you're chasing lap records or looking for a more consistent feel through a long main, this is a top-tier upgrade for any serious racer.

Advanced Engineering for Maximum Efficiency This isn't just a simple motor swap; it’s a precision instrument. The armature is factory-balanced to eliminate vibration at high RPMs, ensuring smooth power delivery throughout the throttle range. The innovative endbell design and bottom-case intake scoop work together to pull air through the internals, preventing "thermal fade" and keeping your magnets strong during intense sessions. Plus, the new brush holder design makes maintenance simple, ensuring your motor stays in peak condition.

Key Features & Technical Specs:

• Japanese Precision: Equipped with high-quality Japan Ball Bearings for significantly reduced drag and increased longevity.

• Balanced Armature: Factory-tuned to ensure smooth, vibration-free rotation even at maximum throttle.

   

• Superior Cooling: Features a new endbell design and a bottom-case air scoop intake to maximize airflow and prevent overheating.

   

• Pro-Level Maintenance: Modern brushes and a new holder design allow for easier upkeep and consistent performance.

• Efficient Power: Designed to deliver a linear torque curve, giving you a better punch out of technical corners.

• Standard Fit: 130-size motor, compatible with most 1/28th scale racing chassis.

Hobby Hideaway Pro Tip: When installing this motor, ensure your chassis has a small amount of clearance around the bottom air scoop. If you're using a lexan body, trimming a small vent near the motor can further increase the cooling efficiency of that intake scoop, keeping your RPMs high and your motor healthy!
