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 for each additional item! Example: 2 items total discount of 200 yen, 3 items total discount of 400 yen. Broken in for FM use. Rotation speed: 33591rpm No-load current consumption: 0.81A 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: Rotation speed Third photo: Image of the motor's end bell Measurements were taken under the above conditions, but please understand that there may be slight variations in the numbers due to the time elapsed since listing, shipping conditions, and the measurement environment. ※Based on personal experience, I feel that the breaking-in condition of the Power Dash has the following tendencies (there are individual differences, so this is just a tendency): • 33000-34000rpm (0.7-0.9A is average) Torque remains, battery consumption is moderate, and it runs well even with alkaline batteries, so it's strong even in official races (can adapt to official layouts with different speed ranges each time by adjusting the gear ratio, I have multiple championship wins in the official CP class with this kind of motor), can be used in layouts with sudden braking, and long-distance layouts with Ni-MH batteries. • 34000-35500rpm (0.8-1.0A is average) It's quite fast on flat surfaces, and I feel that the balance of speed, torque, and heat resistance is good in 3-lane high-speed layouts. • 35500-37000rpm (0.9-1.1A is average) While it becomes even faster on flat surfaces, heat fatigue becomes a concern during continuous running, such as from sudden braking and races. It becomes necessary to be mindful of battery management and cooling the motor. • 37000rpm or more (I think it will be 1.3A or more) There is a tendency for torque to be lost, so it will be fast in layouts with shallow braking or long flat surfaces. Also, those with a no-load current consumption 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 the speed may not match the rotation speed, so test runs are essential. I don't recommend it much because the balance is poor.
