Product Usage:
All AndyMark gearboxes require grease for proper operation and long life. We suggest using our red tacky grease, am-2768. We also encourage that the user powers the gearbox continuously for 30 minutes without grease to allow the gear teeth to wear in. While we do design with short run times in mind, this 'run in' period for smooth gearbox operation, is recommended. Once this is completed, thoroughly grease the gear teeth periodically to ensure smooth operation.

Product Overview:

This 20-inch-long Nano Tube houses two complete gearboxes, each having the same gearing and shafts as the Nano with 500 Key Shaft. Nano Tube accepts two 2.5 inch CIM Motors. Hardware is included for attaching this motor.

This product is intended to be used as a complete drive module for the side of a 4-wheel-drive robot. A second tube is to be used on the opposite side of the robot in order to make the complete drive chassis.

Reviewer: Preston Purdue  
From what I can garner so far, this system should work excellently for a compact demonstration build.
One Qualm: It comes pre-assembled :(
