I would think, unless Lego was willing to make new tires, that some small balloon tires would look perfect, aside from tread pattern. I just hope they do something like the offset arm, to maximize the pneumatics. I could see this set as not really having a b model, but would include parts and instructions to make 3 or 4 of the configurations shown.

This .gif is worth a thousand words: Courtesy of Mahjqa, this animation shows that if the pivot point of a wheel is closer to the center of the wheel, then the fenders can be made much tighter. This is important for making models look correct. A problem with some models is that if the wheel wells are too large, it makes the wheels look out of proportion. Aside from looks, having the pivot point in the center reduces tire scrub, and make it easier to steer the vehicle, while reducing bump steer.

So, I was fooling around with one of my many bins of parts, and I came across some X-pod parts, specifically these: Milan had me thinking about building wheels with good and realistic offset, and that got me thinking, would this fit in a 94.8 tire? As it turns out, it totally does. And, it's a pretty nice fit. I can't move the tire relative to the wheel at all.

If anyone is interested, I've got a concept version of the 42052 rotor head, on my Brickshelf gallery. http://www.brickshelf.com/gallery/saberwing2/Ideas/42052_rotors.lxf

I have figured out a couple of prototypes for how the rotor assembly of 42052 might work, but I have run into a number of problems. Using the 28z small turntable with any gear results in a weird gear ratio, and there is no way to get around that. Same thing if one were to drive the big turntable. The only way to make the blades turn at the same speed is to use the new 60z turntable, and then have a 8z-40z combo drive the upper rotor. So, there are 3 options for Lego to do this. They use the method 70170 Ultra copter uses, where the lower rotor is driven by the turntable, meshed with a 36z double bevel gear, and then the upper rotor is driven by a trio of 16z gears. This is a proven method, but the result is that the rotors turn at different speeds. My prototype uses this method Lego introduces a new 28z bevel gear, and uses a perpendicular 12z gear to drive both rotors. this solution would be most elegant, but would require a new part. However, I can think of multiple uses for a 28z bevel gear, so it's not that much of a stretch. Lego uses the 60z turntable, and an 8z-40z combo to drive the upper rotor. So, what do you guys think? Would Lego introduce a new part, or have the rotors spin at different speeds? Also, if you are wondering, I have the prototype assembled, but my camera is charging, so I will show it later.

Here's a link to the valves M_longer is talking about, the builder made some instructions for it. http://www.brickshelf.com/cgi-bin/gallery.cgi?f=513295

Howdy folks, I decided to do some stuff in regards to the 42052 B model. Lego 42052 rotors by Saberwing007, on Flickr I managed to do a representation of what two tandem rotors with the blades from 9396 would look like, and how big they would be. As can be seen, there is significant overlap with the blades, but that would be correct for a Chinnook, as seen in this illustration: But, seeing this only raises a lot of questions. a coaxial helicopter is rather stubby in relation to others, but I could see this being done with a model 50cm long, which by coincidence would work for the two rotor version as well. Just, give us the pictures already.

That's not what they are asking. This system does not even have a name, and the name they suggest is as good as any.

Well, not in the same sense that cars do, no. But then, neither do most go carts. Edit: As I have found out, most top fuel dragsters have a multi clutch pack instead of a gearbox. Usually, some of the clutches have welded together by the end of the run. But, I've heard that the non nitromethane dragsters often have a transmission derived from a 2 or 3 speed GM Powerglide, but heavily uprated and with a clutch instead of a torque converter.

Why do I feel like we're missing something with the prices? I just do not see the Helicopter being the same price as 42042, which you can clearly see from the screengrab. I converted the prices, and it still comes out the same. So, I don't think the prices are accurate, at least for that particular set. As for the dragster, I don't really see it being able to wheelie on its own, at least not without some internal mechanism. I am aware of a Racers set, number 8667, that could do a wheelie on its own, but that set would be tiny, and then there is the part that pull back motors have enormous torque relative to the weight of the model. Finally, if the price for the mining loader is accurate, the simple claw arm is inexcusable. But, the b model sounds interesting. I'm not sure what to interpret "Mine Cutting Machine" as, because that could mean a lot of things, including a road header. But, the only wheeled mining machine that I see as being likely is this: It's a large rock wheel saw, but I recall these being used more for trenching than mining. Another possibility is a tunneling jumbo, like this but with only one drill:

I don't think so. That model has PF and is mostly a System shell with Technic underpinnings. I think that the actual set would look more like this: It would be more like this, but with some newer pieces, particularly the fenders, and maybe without pneumatics. I don't see a set like this with PF, at least not full RC. I also don't see this set as just being the tractor, even if they somehow implemented hybrid steering and the cab moving. I don't really find a tractor that interesting on its own as a set. So, if it indeed had some implements, what would you like to see?

Looking good, you might actually be able to give Milan a run for his money in terms of looks.

Cosmic Boy? What was/is that? A new Marvel thing or similar? Edit: a simple Google search let me find it. It's a new DC superheros thing.

Regarding the mining loader, I find it kind of odd that a presumably $50 set, or even a $35 set if it is around 350 parts would have no mechanism for moving the arm aside from a manual lever right on the arm. If that is the case, I find that to be bullpucky. What's more, it does not appear that the claw can tilt, whereas a real loader would have the ability to tilt whatever attachment it had. Excuse me for sounding grumpy, but I think that it's Lego being lazy like 42037. If you're going to make something up, make something up, and don't call a sand rail a formula off roader. I don't understand why they could not make it with a bucket like, I dunno, an actual mining loader, or call it a waste handler or something like that, but no, they have to call a fish a fowl. I have to wonder if the sets are named by the marketing team, who might not be familiar with what vehicles the sets represent, especially for something like this.

Well, it is a bit moot, but you are forgetting the fact that almost all crawler cranes need extensive cribbing, to support the weight. Also, most crawler cranes actually have a lower overturning moment than a comparable mobile crane, meaning that a larger one has to be used. But, your point about pick and carry still stands.

Funnily enough, the magic number most crane makers go for is 10 tons per axle, which would mean that the 96 ton QAY 2000 is within limits. Although, I have actually heard the weight cited as 325 tons, but I don't know if that is with ballast or not. 96 tons sounds suspiciously low, I'd say it would be more like 120. By the way, where did you find the brochure?, I'd like to take a look at it. As for the fast turnaround times in relation to crawler cranes, a 2000 ton crawler crane would take multiple weeks to set up, not a day. Plus, you'd have at least ten or so truck loads to keep track of, possibly more, with a crawler crane, whereas with this you'd probably have 4 or 5. I thought pulling permits for this thing would be ridiculous, but it might not. Oh, and about the domestic market, do you have any idea how huge China is? They're investing billions, if not trillions in infrastructure, and that is what this crane is capitalizing on. And, I don't think it's aimed at just wind turbines. I think I read an article saying it could be used in many applications, including chemical and nuclear plants. As a matter of fact, the 2000 ton capacity is not that significant, relative to the crane's ability to lift things at larger radii. Plus, a crane like this would be much easier and faster to move on a job site, in relation to a crawler crane, because the boom does not need to be dismantled.

d'oh, I was just about to post that as the other possibility. Well, good luck with it. Maybe you could actually replicate the power:weight ratio, like newtons to grams.

Most of the above is what I have been able to observe. The construction details and b models are more speculative, but the colors and parts are as factual as a preliminary observation can be. As an aside, I kind of wish that Lego would include different options with some models, like 42042 could have a hook or grab, or 42049 could have a grab or bucket.

You're not building a Koenigsegg Regera, are you? It's a low, sleek car, and it has been called a Megacar, due to the engine putting out 1 Megawatt of power.

Here we go, parts and stuff for every set: 42045 New parts: Fairing around rear is made of two new panels, in blue New colors: 42039 fender in blue on rear wing. I've got people saying the 7L flex axles are new, but I don't think so. B model: Stunt plane. 42046 New parts: none New colors: Gold small rims. Some other parts look not quite black, but that could just be lighting. 42047 New Parts: none New colors: lime rims, apparently a 7l axle in yellow. 6 white micro panels. While those are not new, they were only seen in 42043 previously, which means it will be much easier to procure them. Combo model: Unknown. In the previous pullback duos, the combo model is not telegraphed by the individual sets. However, the wheels are the same size on both of these sets, possibly indicating that the combo model will use all of them. 42048 New parts: none New colors: 4 purple 42039 fenders. red 4l axle. Sadly, part thought to be orange half bushing is probably just a 1x1 round tile with a sticker on top. Construction details: There is a red gear on the same axle connected to the rear wheels. Unless Lego has decided to make the 3L differential in red, we can reasonably assume it's a clutch gear. What that would mean is that the model has a 2 speed gearbox, shifted by the red lever on the seat. I really can't think of anything else it could be. Ironically, we fans have been griping about lack of speed changing gearboxes for years, and now we get one in a vehicle that rarely has them IRL. Oddly, there is no visible connection between the steering wheel and the front wheels. That part of the mechanism is likely obscured, but if this vehicle does not have steering on the main steering wheel, Lego screwed up big time. B model: This set does not appear to have any good parts for making anything else, other than another car, so I'm going with some kind of dune buggy. 42049 New parts: New panels in yellow. New colors: Hero Factory container in red Construction details: Given that this small model still uses the new 60z turntable, it looks like Lego is going to discontinue them. On the other hand, it means that the new turntable will be far cheaper to buy. This set is, no matter how it is sliced, weird. I have never seen a loader like this with a grabber, yet it has one. The grabber arm too raises more questions. Having it be manually operated in a set like this with little else going on would be a waste, and luckily I don't think that's the case. All of the pins in the arm are frictionless, which would be a massive design flaw in a manually operated feature, as the arm would just flop down if raised. But, there is no other mechanism readily apparent, nor a knob to operate it visible on the vehicle. Further, there is a sticker on one part of the arm, which could indicate that it is used to position the arm. My thought is that there is actually a mini Linear Actuator somewhere in the front, but not visible in this picture, and that lifts the arm. B model: Articulated, 4 wheel vehicle with a grab? The b model is likely a log skidder.

There is, as a matter of fact, a real crane with 12 axles: the Zoomlion QAY 2000. As its name implies, it can lift 2000 tons at 3 meters, making it the strongest wheeled mobile crane in the world. At least, that's what the company claims. There is little information on the real crane on the internet, and I can not find any confirmation that anybody has actually used it. It's a huge, ugly monstrosity I also have been planning a version of a crane with 12 axles. (For more than two years now.), but mine is not based on this. Rather, my version would be a theoretical 2300 ton capacity Terex crane.

Looks ambitious. But, your steering system might have issues with slack, and gear racks not centering correctly. I still wish you the best of luck with this.

I'd go with 42000. You can always get 42039 later, but overall 42000 is far more interesting technically, and has 3 mini linear actuators.

A rotary pneumatic motor would be great and realistic, I'd also like to see a rotary pump, and maybe some self centering valves. Also, if the IP Car is RC, I want it to be true radio control, none of that crappy IR nonsense.

First part: No, and as a matter of fact the rear axles of some vehicles with all wheel steering barely move. Essentialy, the rear axle turning would reduce the vehicle's turning radius, as if the front axle turned that much farther. The rear axle can steer as much as the front one, but in most vehicles its often less. Second part: No, trailers usually work the same way any other vehicle with multi axle steering would work. However, with trailers, like a ballast trailer, the first axle behind the truck is fixed, and then the rest steer. Contrast with 42009, which has the fixed axle in the middle.
