what you have there is ackermann steering. you should attach the wheels to this part If you want to keep the ackermann geometry, you should find another way to steer it.

but porsche provides enough parts to make a good C-model, ehh, that would be a B-model i guess. nevertheless, i'll go for the BWE as well.

so if i use picture from your site and put it as an image here, i use some bandwith? (deleted technicopedia logo)

my grandma, where i sometimes slept over, had this set(from an ucle of mine). I wanted to build it but a lot of parts were lost or my uncles brought it with them when they moved. I only built the yellow upperstructure. I was 12 at that time and i had no problems with it. by now i realise how difficult the instructions were at that time compared to nowadays. my father has instructions for the B-model. as a kid, i remember looking at the instructions, but not being able to build it.(no parts) i am actually too young for this set, but i have good memories about it.

this is also why i like chemistry so much, imagine the possiblity with atoms, or even smaller particles What i also like about lego technic, is that you can make stuff which actually does something. you can accomplish so much with lego, the only thing you can't do is flying. so litteraly: the sky is the limit

I am also very fascinated by mining vehicles! and ohhh, that truck would be sooo awesome!! :wub:

well, you have to start with having a rough idea - what are you're skills (with lego of course)? - what parts can you use, do you have nxt, pf? - what exactly do you even want to build? - how can you accomplish some mecanisms (look at the real world)? i hope i have helped you a bit

the month. So will it be online again at 1st june? 100gb does somehow not sound like a lot, (i have 10x that much on my laptop) but i'm the opposit of experts about sites building etc. :laugh:

I have the same problem, i thought maybe it's just me, but i'm not. I think i wait before PM'ing blakbird

oh yeah i forgot that. I know it is mentioned in the video but i watched it a few hours before.

i did some math using max steering angle(24.4o) and wheelbase (2456mm). i want to know the turning radius. using some goniometric rules i calculated that r(line going through left-wheels) = 5413mm. Because we used a 3-digit value to calculate it. our answer must me 3-digits as well. that makes 5.41m. But this is not the turning radius. The width of the car is 1,880m. 5.41+1,88=7,29meter. the values are true, but i don't know if i calculated the correct thing. anyways. lets take turning radius and divide it by length. on the real car, that is 7290/4545=1.60396 on the lego car it must me about the same. I don't know the length but we know, that the turning radius of the 42056 must me about 1.6 times the length of the car to match the real thing. I wouldnt complain if the turning-circle is smaller, but i do if it is bigger.

using pf and train remote control would give you 7 speeds for one motor(if you count 'not moving' as a speed) and 7 for the other. 7*7= 49 different patterns. right?

That is unlikely in my opnion. This is an ultimate set! It should take the maximum out of lego parts and have a minimum of flaws! It also is a children toy. The 16+ is close to adults but even for teenagers, you better make not a rubbish set so people can improve it.

i get the feeling that they wanted the working paddleshifters and the truly amazingly shaped bodywork so bad, that the rest got sort of lost. But the bodywork is truly amazing and very well shaped.

what i also noticed is, the positions of the cilinders. in lego it looks as following if you look at a motor at the side: [up-down-up-down] and in the exact middle they have the exact same position. in the video, you can see that the positions are different and that the piston-heads never line up.

I'm not the most critical person, but that steering angle is just too bad. All sets have a pretty large turning angle IMO, but this is just ridiculous!

So what for special parts does it have: - gearracks - buckets -tracks -LA's - small chains (truck) (watch 42035 review by sariel @0:39) - wheels (truck) - normal turntable - panels - 3x11 - 5x11 - 5x11 with cut corner - that new panel from go-kart It has a wide variety of parts. Thanks to the mine truck which is included. Is this the first set to have wheels AND tracks? of course it has lots and lots of axles, beams, 5x7/5x11 frames, pins, and some gears. this set offers a lot of useful parts. I definitly will get it this summer. or next one.

#14 - 3 points #7 - 2 points

thanks! I will try to put the motors close to the wheel indeed. added later: That's a neat way of doing it! But i want my model to be a bit bigger.

Like you said, the first two are useless for me. The others however are interesting. I want to take a look at the mars rover itself aswell. thanks for the suggestions! yes, it should be stable because the point of gravity is lower. It must not be too low otherwise it will slew over the ground all the time. but thanks, i'll keep that in mind. thanks for all your tips. It is a very good idea to build an unsteered version first! I have no nxt's and servo's so we will see how the steering will work out. I'll remember to put drive on all 6 wheels. a pity that you're project never got finished and i am suspecting the same is going to happen with me. I will give it a serious try at least. oh, that's interesting. can you please tell me what contest it was? i have no idea how big it is gonna get. but i think i'm gonna use the arocs wheels. It are my biggest. I can use turntables but i have only 2 small and 3 big ones (1 modern one) so it's not possible to use that on all wheels. thanks for your reply. also thanks to everyone who i didn't quote

Hello guys, I was just scrolling through the 'uncommon-suspensions'-topic when i stubled upon a picture of the rocker-bogie suspension. I don't know what happend but i was immidiatly fascinated and i iam thinking about building it in lego. Right now, i'm just in the phase of orientation and research so have the feeling i'm a little bit early with my topic anyways, i am just really fascinated by how it works and i have googled a bit. I'm a really unexperienced builder so it may turn out into a fail. To be honest i never finished a MOC but i hope this will give me a push to finish it. it would of course be nice if it is remote controlled driven and steered. I have no recievers by now. But when i need them (i promiss ) a lot of time will have passed by and in the mean time i have already bought a few new ones. I am wondering really hard if i will come into that stage but that's another topic. the most difficult thing will not be to build the structure i think but i need axle 1&3 to be steered and the middel one to be driven and that all in such a way that it is not a pain to look at. I don't think that it is really needed to drive the 1st and 3rd axle to be drive because all wheels are touching the ground always. then there is another problem. the left and right side must have the option to move relative to each other, so where should i put the connection and how do i made the connection sturdy without limiting the movement to much? do you guys have any ideas and tips? they can be about above problem or just general biulding tips. they are really, really welcome, especially the beginner tips I don't know when i will start building on this moc, there are a few more creations? at my working table and i have to do some research first. Let me know what you think!

Interesting. I really like this kind of information! I was not talking about the kind of plastic though but I'm sure you got that.

if it has friction, the beams have a much stiffer connection. And after short thinking, i really can't come up with examples where you want that pin to be frictionless. - If you want to rotate it, for whatever function you like, you would more likely use a normal axle. - If you use it to attach something(which is it's basic function) it is just locked in place and the pin can't rotate so the friction brings no problems again. If you want a beam to rotate, you should be able to use a axle because there already is a axle hole. ho

he guessed right anyways, but i don't see it either. Maybe i'm just doing it wrong. EDIT: sorry, i didn't reload my page so i didnt read blakbird's reply, please ignore this post.

i like how the power-puller is such a unique set. It has the PP-tires of course, 20(!) pistons and it contained a VHS-tape. I wonder if 42056 will also be a unique set like this over 15 years or so. (and 100th post yeej)
