CIM-U-LATOR == 0.5 lb each

Total weight savings == 3.1 lb (top only)

If you add the CIM's to the bottom, it's a net gain of 2.5 lb. Is that in your weight budget?

If you can (I know it's late in build season), shortening the robot as others have suggested can be a big improvement. CoG goes down, angular momentum goes down, stability goes up. Our team did this, and we believe the advantages outweigh the disadvantages.
