3 segments would drastically reduce the most interesting part of this build I think. Id stick with the number of segments and increase the amount of cylinders.

I don't know if you own them, but have you considered using the gear arcs found in the BWE set( and the new crane)?

I have to agree, this is not a LEGO technic MOC.

I'd say build a ride, don't try to EXACTLY copy an existing one, And if you want to base it on an existing one see what you can improve upon the real thing! It's LEGO! You have billions of options to make a ride, and the limitations of the real builders are not always our limitations! Take my rollercoaster, It's cool but it wil never be a real world thing because it's to complex to be affordable to maintain and keep up with all the safety checks a them park has to do. I was not held down by those restrictions and thus I went outside the box, and I think that's one of the beauty's of LEGO!

Nice idea, I'm following this one.

Letting it bounce is a very tricky thing, the cables must tension up enough after release to prevent the car from hitting a pole. If it's loose enough to bounce, it might be loose enough to hit a pole I imagine... Looking at the video mocbuilder101 posted I'd say loads of pulley's is the way to go, but making sure the string can't snap off the pulley's is an issue maybe? spinning the cart is fine, twisting the cables is not, maybe a swivel mounting option for the car?

@Erik Leppen Not sure what space you have to work with, but what if you use a clutch like this: That way the mechanisme is probably not affected by the slower turning of the turntable, and the actual mechanism is engaged when a higher speed is introduced by a motor Direction of spin might be an issue, I'd expect it to "grab"a lot better in one direction and less in the other. Maybe you can get around this given you don't need a lot of torque. I've never used this technique myself, sow maybe it doesn't work at all. Hope it helps! PS: Maybe you should open a topic because this is not really the place to discuss this (sorry Jim).

UPDATE! Man this thing is BIG! All rings are working perfectly! I'm quite pleased at how ridged they turned out! It had to be because the bench is very complex and densely engineered making it quite heavy. It took a while to figure out how to properly drive this thing fast enough without causing to much strain on the gears. It turns out I just needed to add more motors, luckily adding motors is my specialty. Basically all spinning parts are done now, maybe just some tweaking. Next up is strengthening the main structure.

I made a mini video on the progress: I'm quite pleased so far! This thing is very heavy, and I'm truly surprised at the speed it change direction given the amount of mass in motion here! I did find out the hard way there's a lot of strain on certain gears Those places have since been fitted with stronger gears. The overal speed is okay as is, but these battery packs are quite empty so I imagine it will pick up even more speed! Ow, and I also added lights The crocked part on the underside of the bench is a wire management fault that has since been fixed Next up is motorizing and reinforcing the outer ring Yes it is, BLACK, YELLOW, LIGHT GREY, DARK GRAY and a boatload of motor's and SBricks! In THIS VIDEO I explain why that is if you're interested. thanks!, you too! Lets just go wild and have fun!

Lol, the second twin of the contest! The Icestorm and I are also building a similar attraction

EDIT: IT'S DONE: scroll down to see the full final build and all pictures! As it appears, I'm not the only one who came to this idea give The_Icestorm is building basically the same thing I have some ideas to make the difference more noticeable and give it my owns swing so we;ll see where it ends! Anyway, here's a first look: Let me know what you think!

Yes I can, there's a video on my channel and a topic here on EB: TOPIC Id say the masive 360 dual gatling/laser cannon could end their suffering...

Wahaha now they're really gonna be twins! At first there was at least a difference in scale but mine is in this scale aswell and even quite a few of the same techniques... I guess I should start a topic too soon, I haven't come around to it yet because I was finalizing the video of my 6x6 zombietruck MOC I just posted. Ah well

This is the ULTIMATE zombie apocalypse truck! It can attack, defend and build! I've always loved zombie movies, and the last few years I'v relay enjoyed the walking dead! However... they always make terrible decisions, a lot of them because they don't have a chance to build a secure base that no one dares to mess with. So I designed this vehicle as an ultimate doomsday preppers truck. This truck deals with the 3 biggest dangers of a zombie apocalypse! Hostile survivors won't even dare to try anything, randomly wandering zombies and even the hordes don't stand a chance and going out for supply's with this thing watching your back gets a whole lot safer! The nose opens up and acts as a funnels to guide zombies into 2 massive circulair saws. When the nose is closed it forms a wedge capable of plowing through hords of zombies or obstacles. On the rooftop there's a dual-gatling gun and a high-powered laser canon. The wheels are spiked and both sides have an active anti-climbing defence. Rebuilding is crucial to long term survival in a zombie apocalypse, so the rear has a strong multi-purpose arm designed just for that. It can take a variety of accessories. It uses a total of 14 motors 5x PF L motor 4x PF M motor 2x PF XL motor 2x PF servo motor 4x PF lights 2x 9v siren 1x PF laser 1x PF L or M motor in the attachment crane or drill 5 SBrick's 2 PF battery boxes Let me know what you guy's think!

well... that's... I started working on this same design as well... I guess we'll see how well they measure up to each other then

Nice contest! I might just enter! God I wish I could submit this beast: Ah well, Ill figure something out! I do hope some prizes will be made available!

interesting topic! I started out in the realm of studded bricks and played around with that most of my childhood and it peaked when I got the first mindstorms set. Sadly it died down around age 13 when I thought I was to cool for lego. At age 19 I came to my sences bought my first studless set (8275 bulldozer)with PF motors. I instantly fell in love wit the new style, parts and the PF system and bought a second 8275 the same month for parts. Those 2 sets were the bulk of my technic parts collection and that's where my love for the black and yellow theme was born. This is my first mock with the studless style: Motorized functions became my world, but I was limited by the maximum of 8 channels in the world of PF IR, I found that with mindstorms nxt and a thirdparty part called hitechnic IR link I could expand to 11 motors and program it. this was my first MOC with mindstorms: I went into a dark age and sold all my lego(). when I came out in december 2016 I was thrilled with the potential of SBrick's 64 channel limit and instantly bought 4! My mechanical knowledge went up significantly in my dark age and higher build density and complexity was the result. I built a loop with as many conveyor techniques as I could to learn to use the new parts This was my first build after my dark age to reacquaint myself with LEGO: All the positive reactions on this video(mostly from this forum) motivated me to start my dedicated youtube channel. That's where the madness began and I started hording SBricks and PF motors... This is the current collection: And this is what I build with it lately: It contains 19 motors, 6 SBricks, 4 lights, 1 laser, 1 electromagnet, 2 sirenes... yep , I went bananas! Looking back I clearly see I have drastically increased in complexity when the limitation of the number of parts and motors was no longer an issue financially.

definitely Sbrick, I've used them extensively and they work great! I really love the possibility to use several at a time(I use up to 5 at a time!), and this seems more convenient with SBricks If you wanna see multiple SBrick's in action check out my youtube channel in my signature below ;-)

I like the out of the box thinking but mechanically I can't see any advantages for suspension. I do see potential for this technique in other applications given the fact that you could potentially make very long travel in conjunction with THIS PART(axle flex might be an issue of course). Thank you for sharing !

@Bartybum mostly something that went on in lego technic groups on facebook

It's a different world nowadays, you simply need to build a shield for trolls. I worked 7 months on my biggest MOC to date, my rollercoaster... I'ts technically complex, structurally challenging, something no one has ever attempted before on technic figure scale and the concept of how the riders cart is manipulated in so many ways is unique as well and it's clear I put a lot of effort in it. You wouldn't believe how many people just saw the video and only said "IS NOT A ROLLERCOASTER!" I laugh myself silly about people like that! Current society teaches people to judge others by blabbering their anonymous opinions, regardless of how un-educated or poorly formed that opinion is or what the effect is on whatever or whoever they judge. It's almost as if what your opinion is is irrelevant, as long as you make noise to make people aware of your existence! People should refrain form judging things they know little about if they're not asked to. No one is interested in an un-educated or poorly formed opinion. I can judge someone doing ballet dancing, but I know nothing about the effort of getting to that point, the degree of difficulty, what it would look like if it was done flawlessly so my opinion would be superficial at best. The art of knowing when you have nothing to add is being forgotten by society, so the art of knowing who's judgement is meaningful is worth pursuing.

I SO agree with this, this in not all that expensive of a way to expand your collection and it massively improves your builds. I do tend to have self-control problems while browsing bricklink...

Hey builders, I made a video about how to get better at building with LEGO technic, and I wanted to post it here so it might help some of you guys. Jim helped me with some of the research and Sariel even provided me with a few copies of his book to give away!

Simple, but nice! Keep up the good work!

So I started my first GBC, and I'm looking for some info I cant find... I just saw a GBC video and they talk about a first time builder using LEGO chain, and that that's a very bad idea in terms of reliability and it got me thinking Is there a list of parts that should be avoided in GBC's to make sure they survive long term operation? And if there's not can someone tell me what parts to avoid?
