This is a high-speed, low-friction processed gear, created using my experience with flat races and fence cars. Many others are selling similar items, but mine is designed for use in mini 4WD, maintaining torque transmission while also being suitable for layouts with elevation changes. I've adopted the design that achieved the fastest acceleration after 50 sets of trial and error, so please give it a try! ✨‼️ It performs best when combined with my motor pin shaft and SLIP STREAM070!
