    Hi i was just wondering can i post my own instructables on this?
    It's a modded version becauase 1 less blue ones because alot of people (including me) don't have that much of blues and 2 it uses a different motor because again people don't have (including me) that kind of motor

    p.s.i will credit you!

    It appears that you have different views of the exact same step or do you make three of the exact same piece??

    When it says 1-3 instead of 1 then 2 then 3 it means it is just different views.

    Ya I thought so, we just did that and it worked (kinda). There was a few fundamental errors though, mostly the chain, it kept getting stuck different places :(

    I don't quite get if your connecting the steps each time or making every individual step THEN connecting them, like, I know you connect at the end, but im wondering if you connect 1 and 2 and 3 then make more and connect that, I just don't get it really, plus the last picture is a little too close so i cant tell how to connect everything............ have any um.........suggestions?? Thanks.

    You just connect the smaller parts in each step and at the end you connect all the steps.

    No you make each individual step and then connect all the steps at the end.
