We should suggest LEGO to deliver that piece instead of the 1x9 which is crap - no idea how they got it to work for their videos though.
Only problem might be that you have no 1x11 piece left - I took mine from Mindstorms set.
I have an extra 1x11 technic liftarm, so I wanted to try this out. Which ball end do you put into the 10th hole? Is it the one that connects to the bar, or the one that goes inside the rubber band?
