Thank you for viewing! I put my heart into making these 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 excellent race and time attack results from many repeat customers. m(__)m Immediate purchase is welcome. Mach Dash Motor PRO High-speed, high-torque break-in 39000rpm range, set of 2 Great value 1790 yen each (usually 1980 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 an antimatter device, at 3.0V forward rotation, with Giri (app). 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 motor individual differences, the measurement procedure in the product photos is consistent with measurements taken within 1 minute immediately after breaking in and cleaning the motor, and the price is set accordingly. These are items managed by an individual, so please refrain from purchasing if you are sensitive or seek perfection. *This is a set product, so it is not eligible for discounts. *I have opened and broken in new motors, so I have listed 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 the fastest times in races!⭐️ #Mini4WD #MachDashMotorPRO #Mach #MSChassis #MAChassis #BreakInMotor #Motor #MotorBreakIn
