Highly-Efficient Gearbox
This gearbox features a highly efficient motor that can be powered by either 1.5-3.0V alkaline batteries or solar panels (0.5V, 1.5V). The compact gearbox is made from transparent ABS plastic. High efficiency means a long running time, and three different gear ratios enable a wide range of applications. Gearbox attachment holes feature a 35mm distance to allow compatibility with separately available universal plate products. The set also includes a 3mm hex drive shaft and crank plates, which can be used as wheels.
