Ideal for robotics and model projects requiring customizable speed and torque, it includes all parts and two crank plates for easy assembly. Trusted by hobbyists with a strong 4.3-star rating, this 82g plastic gearbox runs on 3V and delivers reliable, precise mechanical control. ## Description The mini-motor gearbox kit from tamiya makes it easy to get a small robot or plastic model moving. The kit includes one brushed DC motor and all the gears and parts to build any of the four possible gear ratio configurations: 71. 4:1, 149. 9:1, 314. 9:1, or 661. 2:1. The four gear ratio options provide you with the flexibility to choose the speed and torque for your project. The gear train of the low-speed gearbox includes a self-locking worm gear, which means the gear train can not be back-driven (the motor can spin the output axle in both directions, but you cannot turn the output axle with your hand). Not being able to back-drive the gear train is useful when powering vehicles that stop on steep inclines, or when powering mechanisms that lift heavy objects off the ground (like gates or drawbridges).
