Two Idlers, Two Cogs, and 40 Tread Links - and a pair of GM2/3/8/9 style gear motors. A treaded vehicle is just waiting for this package!
The 100:1 Mini Metal Gear Motor is about 25% more motor than our GM12a (in speed, torque, and power consumption), but has an enclosed gearbox!
This long-motored 360:1 Mini Metal Gear Motor is a torquey, compact brute!
With almost twice the torque of the GM14a, the GM22 298:1 Mini Sealed Metal Gear Motor is the most compact torque monster we have!
