There were several items we just took right off: the empty cell holder, it's associated motor, several large, unnecessary pieces of lexan, and the no longer used camera bracket. We also weight reduced several sprockets beforehand as replacements, replaced the steel shaft collars with aluminum ones, and replaced 2 out of the 3 AndyMark transmission square spacer with individual spacers. We estimated that we were taking off ~7 pounds and then adding on ~6.5 pounds with the fan and associated electronics (extra victor, wiring, etc). But when we went to weigh in officially, instead of the being ~120 pounds, we came in around 116. The scales are supposed to be calibrated, but I heard from other teams that they were also suspiciously a little low. We'll see when we get to Atlanta I guess!!

We realized this as well. We actually had to add a few chunks of aluminum to get us back up to 120lbs. I wonder if they even bothered to verify weight of the scales.

Another reason...
