The 100:1 Mini Metal Gear Motor is 25% more powerful than our GM12a (in speed torque and power consumption) and an enclosed gearbox. The performance of the GM20 makes it fit between the GM11a and GM12a.The sealed gearbox makes the motor more resistant to sideloads. Note:The motor’s mounting holes are threaded for 2 M1.6 metric screws. Features
