Highly-Efficient Gearbox
This gearbox features a highly efficient motor which can be powered by either 1.5-3.0V alkaline batteries or solar panels (0.5V, 1.5V). 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 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.
