<p>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?</p>
<p>*other than the steering*</p>
<p>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.</p><p>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. </p><p>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!</p>
<p>I Built This About 2 Weeks Ago Its Pretty Cool But There Was Some Pieces I Dont Have Or Have Enough Of So I Had To It A Little Differently But It Still Worked</p>
<p>Wow! Looks cool! I love the rims + wheels. All black, very nice combo!<br>That's the best, find solutions even if you don't have everything.<br>Any problems you encountered when building? I'd like to know so I can further improve :) Thanks a lot for building the model! Have fun</p>
<p>no not really it worked pretty well</p>
<p>I just built this the other day it's really nice! But the front suspension breaks really easy. </p>
<p>Maybe you just are to hard on it?</p>
<p>Woo! Cool you made it! It looks good in standard colours too, I guess. Did you have problems with the part count just like Dannicb in the comment below? Then I'd like to know ofc.<br>What did you use as &quot;shock absorber&quot;? An elastic band?</p><p>What exactly did break? Something like the ball-joint connection? They're not too sturdy, but I didn't have problems with them myself. Thanks for telling me, though!</p>
<p>I used a rubber band. I did not have any problems with the part count I just decided not to build the roof. </p>
I made this truck but you need to re do your parts list I keep my knex at work and counted out only the knex parts I needed per the list so that I could make this at home I couldn't make the roof because you undercounted green/black rods and white/silver rods also blue spacers and clips with rod ends also you can't attach a large clip in the manner suggested in the instructions the pile of parts in the picture is what was listed for the roof that I couldn't make because I didn't have any rods left
<p>I never had problems with it. Maybe you miscounted the parts?</p>
<p>Hi Dannicb,<br>I was very pleased to hear and see (although the picture is upside-down) that you made my model! But unfortunately, with some difficulties :/ </p><p>Could you provide the quantities of parts that you are missing? That would be the easiest way to update the parts list. I am only human, so I do make mistakes. Sorry for that.</p><p>Also, if you need help with that clip, please be more clear in what you mean. Which step? which picture? I made everything myself, and all connections are legitimate.</p><p>Please use interpuntion next time, that makes reading a lot easier.</p>
i like the details! very pleasing for the eye. also nice to see that the model is functional (doors, steering).
<p>Thanks alot for your kind comment!<br>I want to make a video as soon as possible, so I can put it in the ible :)<br>It's up for voting (they have to check it still) for the knex competition, so a vote would be awesome! ^^</p>
i would vote, if i were not in the same contest. good luck to you!
<p>How about a vote for a vote? ;) I prefer our creations above guns at all times :P<br>And indeed, good luck :D</p>
I usually do not vote for vote, but hey, why not? :)
<p>Looks good!</p>
<p>Thank you ^^</p>
<p>Very cool!</p>
<p>Thanks :)<br>Feel free to give me a vote in the knex contest ;)</p>
Very cool you need to find a way to put a motor in it
<p>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.<br><br>Thanks for your comment and vote if you want ;)</p>
<p>This is very cool but do you need to use the little orange parts?</p>
<p>Err, yes? why are you asking? If you wouldn't need to use them, I would have left them out...</p>
<p>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. </p>
<p>I see, well for the suspension and the steering, they are not used (if you mean that by &quot;the funcion of the 4x4&quot;) They just make the rear stronger.<br>Same to you.</p>
