Also, do you happen to know around how much the electronics board in whole weighs? I'm curious as to whether or not this thing would be lighter with a less hefty board.
Very nice, and props on getting something together before the season! I know it's not easy, as all of my attempts at doing this have been shut down.
Props!

Its a sawed off piece of our 06 ramp, I believe its 0.5" thick. We also used four different fuse boxes because that was all we had. I think the major weight came from the Big CIMs. As Cory said, those big CIMs weigh significantly more than the small CIMs. We used them because we didn't have any of the small pinion gears that are needed for the small CIMs in the AM shifters.
Tensioning is really easy. You just loosen three bolts and slide the bearing block into place and tighten it down. And no, the blocks don't slip. The chains will stay tight until they begin to strech.

Even without swapping the CIM's, I'd say they could cut 2-5 lbs pretty easily.

Yes, there are many things we could have done to lighten it. But it all would have taken time and money and the purpose of this system is to create a simple prototype base.
For the competition version we may use 7075 or 7068 aluminum for the axels. Any advice on that?
