How do you get the front suspension to move up and down with the steering shaft. I fell short and ordered the parts, I built the model and it did not really move. Do you know why the travel was well lacked on the driver(left) side? Also, if you have a K'nex man can you put him(or her(your choice)) in?

*other than the steering*

Actually I built the steering centre a few days ago again, and just like you, I found out that its either steering or the suspension. So it's not your fault.

Explanation: Do you see the ball joint + Y-clip that's attached to the orange piece on the steering shaft? Well, that limits the up and down movement. The right wheel has less problems with this issue.

About the K'nex robot (let's keep 'm genderless ;) I'm not sure if it will fit in, never tried it. But I think it should be able to :) Hope you're still satisfied with the build!

Kinda true. But without motor makes this a model availble to almost anyone because the piece count is not that high. Also, a suspension system this small (smallest as far as I know) is very hard to power. I've thought to replicate the LEGO drivetrain system for knex in 3D, but so far no plans to actually do this.

Thanks for your comment and vote if you want ;)

Err, yes? why are you asking? If you wouldn't need to use them, I would have left them out...

Because i do not have those parts and i was just wondering if they where need for the function of the 4x4. Good luck in the contest.

I see, well for the suspension and the steering, they are not used (if you mean that by "the funcion of the 4x4") They just make the rear stronger.
Same to you.
