    i love it. i even made one at scool with my friend. so i built 2 they were both awsome :^)

    nice, i've improved it a bit  (in my opinion) , adding a bigger support system, and changing the arm to blue and purple mix instead of purplr purple ankes the arms a lot stronger!

    The pictures for the top are hard to read

    Cool, but using the Power Tower Cane controler works best for these kind of knex models.
