This is a慣らし済み (broken-in) Power Dash motor for Mini 4WD. If you purchase multiple motors, you will receive a 200 yen discount per additional item! Example: 2 items total discount of 200 yen, 3 items total discount of 400 yen. 慣らし (breaking-in) done for FM use. RPM: 34641rpm No-load current draw: 0.98A Measurement conditions: Measured after more than 24 hours after breaking-in, with the motor's temperature naturally cooled in a shaded area, after applying a 3V voltage for approximately 30 seconds. The photos are as follows: First photo: Current value Second photo: RPM Third photo: Image of the motor's end bell Please understand that there may be slight variations in the numbers due to the time elapsed since listing, shipping conditions, and measurement environment. ※Based on personal experience, I feel the following trends regarding the breaking-in of Power Dash motors (individual differences exist, so this is just a tendency): • 33000-34000rpm (0.7-0.9A is average) Torque remains, battery consumption is moderate, runs well even with alkaline batteries, strong in official races (can adapt to official layouts with varying speed ranges by adjusting the gear ratio, I have multiple championship wins in the official CP class with motors of this level), usable in layouts with sudden braking or long distances with Ni-MH batteries. • 34000-35500rpm (0.8-1.0A is average) Very fast on flat surfaces, seems to have a good balance of speed, torque, and heat resistance on 3-lane high-speed layouts. • 35500-37000rpm (0.9-1.1A is average) Even faster on flat surfaces, but heat buildup during continuous running, such as from sudden braking and races, becomes a concern. Requires careful battery management and cooling of the motor. • 37000rpm or higher (likely 1.3A or more) Tends to lose torque, so it will be fast on layouts with shallow braking or long flat surfaces. Also, motors with a no-load current draw exceeding 1.5A may have excessive current flow due to initial defects or failures during use, resulting in abnormal torque reduction, heat generation, and battery consumption, and may not achieve the speed corresponding to the RPM, so test runs are essential. Not recommended due to poor balance.
