This is a "seasoned" Sprint Dash motor [FM]. Seasoning was performed with a low voltage and a small amount of oil. The rotation speed was measured at 3V using Motor Boot Camp 2. Please note that the rotation speed is an estimate. The seasoning method leaves a high torque, so the acceleration feeling remains, and it is believed to be fast enough for a three-dimensional course. I have actually run it with the same seasoning method and confirmed the torque and speed. Since it has not been used after seasoning, it will be sold as unused. Since it will be shipped after being sold, the motor is stored in a box with a desiccant, but please note that the condition may change during transportation. Even if the rotation speed drops slightly, it will still be fast enough. Please try it. PLM oil is used for storage after seasoning. Returns and exchanges are not accepted to prevent replacement. #Mini4WD #PowerSource #PowerSo #MachDash #SprintDash #HyperDash #PowerDash #MotorSeasoning #HighRotation #SuperFastMotor
