Manual motor cleaning tool for Mini 4WD. Equipped with a 1:48 speed increaser. For example, rotating the handle at a pace of 2 times per second results in 5760rpm. No power supply is required, making it safer compared to conventional power-on types. The rotation direction is forward for FM cars when turning the side with the "F" marking, and forward for rear motor cars and double-shaft cars when turning the side with the "R・C" markings. Convenient for cleaning when the commutator gets clogged during running or during motor break-in. By setting bearings on the pins of double-shaft motors, you can also clean the bearings. If the included motor fixing band is damaged, you can substitute it by connecting three 19mm roller O-rings. Please prepare the countersunk screws, nuts, and spacers to be used for the handle, as they are not included. Material: PETG-CF *For cleaning, we recommend using a parts cleaner that is safe for plastics. We tested WAKO'S BC-9 and Gallium Cleaner 300 and found no problems. Because it may deteriorate if exposed for a long time, remove the holder after use and store it with the cap that comes with the bottle. *We will ship within 1-2 days after purchase. We will contact you if it takes more than 2 days due to work circumstances. *As this is a 3D printed product, there may be small scratches or layer lines from the finishing process. Thank you.
