A little late, but here’s 1073’s 2011 chassis… 80/20 of course :).
How much does this weigh?
It looks like it weighs about 21 lbs.
Yeah it weighs 15-20 pounds, but not over 20. We’ve used 80/20 every year since I’ve been here - always discuss it on design team, and always stick with it. It just works for us, even though it’s heavy. We really wanted to go with a pretty modular design to be able to repair quicker this year so just happens to help there too.
