This is a super cool well designed build. They must have known that the large technic piece could break, so they sent two. However, I think lubrication it would slide right on. Other than that, it’s perfect. Looks amazing and I love it.

It looks like it should, like the previous comment said lubricating it or something has to make it easier. Mine came with two of those poles though, so that is good at least.

Joy qualifies as always one of the leaders for construction sales. Perfect shipping, accurate packaging, impeccable service. This model is great; however, the pieces are often worn and scratched (probably because they are tightly packed together during transport). Perfect instructions, great result. Valuable advice to all: when fitting axles and pins try lightly lubricating them first. They will slide better and you will avert the risk of irreparably damaging or breaking the pieces.
