Large motor test rig

Built a motor test rig to experiment with a powerful Sabertooth 2x25 motor controller by Dimension Engineering.  I suspect that I have selected a motor controller that is larger then required for these motors.  So far this controller is very solid. 

The motors come from old ride on scooters, no specs.  Haven't done any real investigation on capabilities yet.  On the rig now it is controlled by a 5k pot in analog mode.  The goal is to test with each mode.

The power supply is rated at 5amp max and already tops out if significant changes in current occur.  The rig is left over scrap plastic.  Lots of rough cuts to in the motors mounted.  I don't plan on running these with much load so there aren't any vents.  This may change in the future.
