This uses a two motor system to provide power and speed to turn the hex shaft. The Tamiya twin-motor gearbox is a small (3-inch long) plastic gearbox. It contains two small brushed DC motors that drive separate 3mm hexagonal output shafts.
These new hard plastic wheels are specially designed for our GM2, GM3, GM8, GM9 and GM17 gear motor output shafts. Size: 3.0 x 0.7 x 3.0 cm.
This unassembled gearbox kit comes with the motor, two sets of gears, metal shafts, gearbox and other accessories. Use a different gear setting and you will have a different speed.
