If they are frugal with weight and keep it at about 100 pounds w/ battery and bumpers like we did in '11, the Cimple boxes aren't a bad choice. The reduced weight makes it much easier to accelerate, and thus easier on the motors. The speed can be harder to control in tight spaces (probably not the best choice for most of LogoMotion), but it really helps when cruising down the field. Cross-field runs occur in about 4-5 seconds with it from stop, which can really save time

Assuming you used 6" wheels (which is what the OP has), did you do an analysis to see how much faster cross-field runs from a dead stop would be* if you had more than just the CIMple box's 4.67:1 reduction?


* and less current draw, and quicker acceleration and easier control in tight spaces

If you added two more c channels to the outside of the frame, lose the internal brackets and tied the channels into the front and back channels with some L brackets you have have a nice stiff frame.
