These are high-speed, low-friction gears ✨️ that I've created, drawing on my experience with flat races and fence cars. Many others are selling similar items, but mine are 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 trials, so please give them a try! ✨‼️ They will perform at their best when combined with the motor pin shafts I'm also selling, and with SLIP STREAM070‼️ I also welcome bulk purchases ✨️ Get 5% off for bulk purchases & follows‼️ #Mini4WD #Gears #Processed #FinishedProduct #MS #MA #MachDashMotor #HyperDashMotor #TorqueTuneMotor #PowerDashMotor #Oil #BrokenIn
