Our goal was to see if it would flip over, but since we had already decided to not turn on the side of the hill, it wasnt an issue. The center of gravity is nice and low so tipping over endwise shouldnt be an issue.
We have been using nylock nuts on all our major structural fasteners, easier than trying to remember what got loctite and what didnt, and they have not shaken loose so far.

yeah thats what we did... backed our bot up to the back of one bump and rammed it full speed (~10 ft/s) into the other... it got over... but due to the way our mounts are, they were weak and bend on impact... then our bot went over and due to warped wheels and a bit of topheavy it flipped... nothing fell out though (velcro ftw) but yeah hopefully it should be MUCH stronger now... we changed the supports to be hollow aluminum tubes and added triangle supports... and are using bolts+nylock nuts to secure everything... here's hoping its invincible now
