Thank you for viewing! I put my heart into making motors, drawing on my own experiences of winning and placing in races, as well as achieving numerous top times in time attacks! I am also grateful and happy to receive reports of good results in races and time attacks from many repeat customers. m(__)m Instant purchase is welcome. Mach Dash Motor PRO High-speed, high-torque break-in 38000rpm range, set of 2 Great value product 1590 yen each (usually 1780 yen each) Discount total: ▲380 yen I select and break in the motors. Demagnetization and disassembly are not performed. After breaking in the motors, I clean them using my own cleaning method and blow them with an air duster. (I do not use parts cleaner during cleaning) Measurements are taken using antimatter and Giri (app) at 3.0V forward rotation. Measurements are reference values because they vary depending on conditions such as the environment, measuring equipment, cable thickness, deterioration of A parts, deterioration of terminals, and contact pressure. The rotation speed is a guideline and is not guaranteed. However, as a standard for individual motor differences, the measurement procedure in the product photos is consistent with the measurement photos taken within 1 minute immediately after breaking in and cleaning the motor, and the price is set accordingly. As this is a privately managed product, please refrain from purchasing if you are sensitive or seeking perfection. *This is a set product, so it is not eligible for discounts. *I have broken in new motors after opening them, so I have marked them as "like new." They have not been used for running. ⭐️Would you like to enjoy Mini 4WD, such as wanting to increase the speed of your Mini 4WD! or wanting to beat the people with fast times in races!⭐️ #Mini4WD #MachDashMotorPRO #Mach #MSChassis #MAChassis #BreakInMotor #Motor #MotorBreakIn
