That is definitely one of the more unique entries I've seen so far! I like the idea very much! Great work!

I can't say for sure, but I think I heard somewhere that it is simply a spool of wire/line that is attached to the end of the boom, and as the boom extends, the line is unspooled. The drum is connected to an instrument to give the operator a feedback of how long the boom has been extended? In short, it's a boom-extention-indicator-device? Again, I might have gotten this wrong, and I can't remember where I read/heard it

Really nice truck! At first I thought it was just a slightly upscaled copy of the 8109 with a 42043 cab on it, but I can now see the functions seem to work in a completely different way!

I am making progress! Had the day off today, weather's starting to get cold, and I needed a break from the crane project. I have redesigned some functions compared to the initial design, among other things the fourth axle now has a lot simpler, as well as more accurate, steering system. I can't quite remember why I made it so complicated in the first place Also, I built the cab:

"Again"? "don't tell me"? When did I tell you this was fair? I simply said it's a lot of work to make proper instructions, as I'm sure you know if you have worked with LDraw. I never defended the people who buy a copy of MOC instructions with the purpose of reselling it to make money. In fact I didn't even mention that. By the way, this topic is about (at least from my understanding) selling complete MOCs by other builders, something which I think is perfectly fine. Credit should ideally of course be given, and if instructions are not free, then the buyer of the physical model should no doubt pay for instructions as well.

I often find it is the opposite way around. This might just be me of course, but I find it quite quick to make a fairly decent looking and functioning model, while "deconstructing" the model into LDraw, stepping it, making sure to place the parts in the right order, making reasonable sub steps, and then LPubing it into instructions, and finally presenting them in an attractive package is just as hard - if not harder - than coming up with and building a MOC.

Looking good so far, crazy level of details, expecting the final model to be huge! What wheels are you using? Regarding stickers, On this kind of model I say go for it, if the same details can't be achieved with bricks. As far as I know custom stickers have been allowed for all previous contests as well

Hi, and thanks for taking an interest! I'm sorry to say this project has been at a stand still for a couple of weeks now, with TC8 and the future Mercedes Truck contests taking up a lot of Lego time (I'm also not with my bricks at the moment).. But I have by no means abandoned it, I will definitely finish it! But as you can see from the below picture, not much progress has been made since last time (only added the 2nd gearbox and did some adjustments) I will update this topic with progress shots as I reach new milestones

Very nice small crane!

Very true! Though you can't beat home made sausage rolls.. But that's a once-a-year thing (usually around later 2H)... For the rest of the year both M&S and Tesco do the trick just fine Not very healthy though, is it? Well, tasty things rarely are

Well said! People need to chill out!

That is pretty spectacular! Granted, it's not Technically complex in the traditional sense of the word (function wise), but building something this huge with that amount of detail presents a whole lot of other problems to overcome, that most of us are not facing when building more "normal" stuff! Both the excavator and dozer are fantastic models in their true rights! Great work Davekuhh!

Haha, yeah, it's a pretty good resource! Think I've seen most of his videos since getting back into Lego Made a makeshift system for the counterweights and to raise the crane today, and took it out for some pictures, and the limitations of Lego became apparent pretty quickly: It is plastic. It was pretty funny actually, as even this relatively small scale model was swaying back and forth in the wind! Anyway, I took some pics to give you an idea of the size and shape of it when erected, some more and in higher resolution in the WIP Bricksafe folder

What do you mean by "exclusive"?

I just wanted to show you the status of my project for the TC8 contest. So I opted for a Fast Erecting Crane after watching from Cranes Etc on YouTube, being fascinated with the unfolding action of it, and wanting to build something different from what I've done before. It is loosely based on the Liebherr 81K, at least in regards to functions, but the looks are a bit more difficult to get right. First and foremost, this is not very Technical in terms of gears and stuff, but rather a study in truss construction (fundamental in most engineering disciplines), and using pulleys and cables (ropes) to achieve the desired functions. The main jib is close to a meter long when unfolded, but due to the truss construction and guy lines, it is pretty much perfectly straight/level, even if it's hinged only in one point. :thumbup: Like I mentioned in aminich's topic, I've had some problems to take pictures of it as it is very large when erected, but I'll try to take some tomorrow. I have a couple of pics of it in folded configuration. First, here it is on its dollies (I'll probably throw together a quick truck to go with it), all folded and ready for transport. The key function I wanted in this MOC is to have the actual foldability modeled reasonably accurate, so it will be able to go from this state to fully erected and ready for action in a manner similar to the real life counterpart. And next it is sat on its independently adjustable outriggers in the grass, waiting to be extended/unfolded: The outriggers seem to do their job.. There are four of them, in an X-configuration. I haven't done the counterweight assebly yet, but I hope five AA battery boxes will do the trick if placed correctly, as I don't have any more The main tower (yellow) has room for the inner tower (black) that is 5x5 in cross section. It extends to roughly twice the height it is in the picture. The jib consists of three parts; the black one (innermost) and two yellow ones (middle and outermost). The LBG parts are part of the guying system. I know it looks a bit messy, but trust me, it looks a lot more impressive when fully erected/extended Unfortunately, due to not having done the counterweight system yet, it would topple over if I tried to get a picture of it now. Anyway, still some issues to figure out, mostly in regards to the counterweights, but also a good solution for the hoist rope, and the trolley. Hope to have some more progress done by tomorrow!

If you are going to use it as a swivel (as in it would be locked in place if you used an axle through the axle hole), you could use a 3L or 4L "bar/lightsaber" piece ...? It would have enough friction (unless used in a very heavy duty application) to keep two parts connected through the axle holes while still allowing them to rotate relative to each other. I've done this on some occasions, works pretty well

Good stuff! Looking forward to seeing what you come up with and the progress shots! Now, I have to try to take some pics of my WIP as well.. Proving to be a bit difficult, as the model is turning out a lot bigger than I anticipated!

Looks good so far, but seems pretty far off from the source material except that it is a crane on a trailer! Anyway, good stuff, can't remember seeing something like this in Technic before (well, unless you count desert's , which had a sort of crane trailer)As for the LA's, while the total power is technically limited by the motor, I find that by using more than one LA, it will work more smoothly and struggle less. Also, the clutch won't kick in as early. For the steering, seeing as it is a trailer, you shouldn't use a setup like in the 42009. From my understanding of trailers like this, I'd say (since you seem to want to have it driven) place the driven axle(s) up front, and then use proportional steering towards the rear, with sharper angles the further back you get. Syncing this with the tractor vehicle might prove a challenge though? I don't know, I have never built something like this. However, take a look at JaapTechnic's recent Nooteboom trailer, as there might be some good tips there?

What a wonderful accident that turned out to be!

Given that it has been stated that it uses the rotor blades from 9396, I would imagine it will be in scale to those. Also, as it seems to be based off the previously mentioned Kamov KA-27, it is probably slightly shorter than the 9396, but with a similar fuselage size. This is just speculation and reasoning given the info we have got so far. I myself haven't seen the pics EDIT: Or could it be based off the Ka-26?

I'll hold you to that . I know what you meant, it was just funny seeing as you posted a pic of the end/stern of the boat Having seen quite a few megayachts up close, I have to say this one definitely has something rather unique going for it Very mush a fan of the design!

It's called the stern! HAHAHA Just kidding! I know I've said it before, but this is so so spectacular! I'll definitely hire you when I buy my next boat! Sooo, who's the owner?

Regarding the helicopter, if it has the same functionality as the CC2, one doesn't really need more than one motor. I can imagine there will be a "control panel" with gearboxes similar to the one found in the 42042 Crawler Crane. Probably two gearboxes (one for pitch, one for roll (and if we're lucky, a third one for yaw)) with axles going from a motor/gearbox/batterybox assembly, through the stand and up to perform the mentioned functions. I can picture the rotor being hard coupled to the same motor, or possibly with a simple "on/off" gearbox. Sound feasible?

I agree that it's unlikely we'll see an RC car with a functional gearbox.. There's just no practical point to it.. Then it'd be better with a proportional RC system like the old one used in the RC Racers set. However I can see the appeal of a proper supercar like in the old days, but with a realistic gearbox, realistic steering linkages, etc. In summary a lot of faithfully reproduced functions you'd find in a real car. Yeah yeah, "but what about play value" I hear you say.. If done right, it'd be a great set to learn about the mechanical concepts of a car. If it's ultimate, I'd expect to see some nice documentation and stuff relating to the real life counterpart on which it is based, with info, and comparisons of the actual functions etc. This could very well be a great opportunity for Technic to really take things to the next level . I hope we'll not see a 8070 in larger scale

Start to design? It has been going on for quite a while, and a lot of people seem to appreciate it. So far the main products seem to be useful parts that allow for functions and aestetics not possible with Lego. And by not possible, I mean within the desired size and or strength. Building a 3/4 section boom that has good strength, looks and scale is not an easy feat. I know you've been working on something you say will be the most awesomest Technic truck crane ever, but so far you haven't shown anything that convinces me But each to his/her own. Some are more purist than others
