When I was kid, my most wanted model kit is Gundam model kit from Bandai Japan. but I never have a chance to get one or build one. so I purchased this Gundam instruction from Rebrickable to build my first Gundam, in Lego form. I did make some change on dkjodkjo original design. links for purchase this instruction Rebrickable Beware, there are some mistake in rebrickable's parts list.
