Hi Ken,
we also posted this message after your comment on Kickstarter. If your footrest mechanism is broken this is probably due to damage during transport. Based on experience from European Backers (shipping in November) we decided to send to next Backers assembled footrest, because assembling this part made some difficulties. RalphGuide.pdf document hasn’t been updated, but take a look at the newer movie with assembled footrest element - https://wiki.robocore.io/kits:ralph.
We are sorry, that broken mechanism came to you .
