I found some other videos related to how the torsion bar suspension works: And one for a triple differential drive setup: I also found a page that describes a variety of tank drive systems, which could inspire other builders: http://www.gizmology.net/tracked.htm And finally, how to change a track: http://youtu.be/dn1wxSDYz9A

It might be nice to have transparent Technic panels, but I'm not sure how well that would work. If you're not worried about adding some non-Lego stuff, then you could get some thin, transparent plastic, and cut that to size, kinda like how the solar panels are made in 7471.

Possibly true, but I hope with these parts , the holder piece gets made in other colors, like DBG or black, so it can be used in like a large linear actuator. Also, why is the pump blue? It was already a different color from the small pneumatic cylinder, so why change it again? Also, somebody commented as to whether or not it would be 8x8 to satisfy the purists, and the answer is no. Also, it does not need to be 8x8, because of the fact that the particular type of Arocs modeled, the 3245 variety, is only 8x4.

If you look closely at the outrigger, it can be seen that we get more of the new telescopic extension piece. Not only do we get 3 of the new long DBG racks, we get three of the holder pieces that go with them. Unfortunately, all of the holder pieces are red. Oh well, I guess that means we'll be seeing a lot of red Palfinger type cranes after this comes out.

Since when is no exposed studs more beautiful than exposed studs? End the unfair standards, all Lego is beautiful!!!!!!!!!11!!! Real Lego, Real studs. But, really, it's all up to you. I found the .LXF file of 8275, and put tiles over all of the exposed studs on the beams, and for me it did not make much of a difference. You may feel differently, but that's okay.

It's not really a bug, but a baffling thing nonetheless: The Power Functions remote, part #58122, has its frequency selector in the 3 position, but the Power Functions Receiver, part #58123, has its frequency selector in the 1 position.

Looks good, although you may need to redesign your axles, if you keep breaking things.

No, those pieces are wheel chocks. However, it would be nice if it had an air tank.

Oh dear, you've got quite a problem. I've calculated your Triangle, and it has an angle measure of ~33 degree at the near end, which translates to a roughly 60% grade. I have no idea how much of a slope standard Lego trains with standard wheels can climb, but to make things worse, Lego train tracks are not designed to do slopes that steep. I don't think that any train, Lego or otherwise, could climb a slope like that. I mean, the steepest non-rack railway in the world is a mere 14.5%. What I'm guessing you want is a single locomotive car, and a single car with machine guns at either end, and crates in the middle. At this point, I'd suggest you actually have a monorail system, with brick built tracks. That would give you the slope you need. I would recommend that you contact @Mark Bellis, because he has done a lot of work with that. But, since you are a new member, you will have to make 8 more good posts in order to unlock private messaging.

I'm going to counter the above, which is odd, as I'd usually be the voice of doom. You may have gotten a prototype, and/or special production part. Sometimes, on Bricklink, you get parts that were not included in any set, and were either made as parts for Legoland model designers, or just prototypes. And, once in a blue moon, a former Lego employee sells them. Just talk to user 1974, he has a shocking amount of prototype parts. Crowkillers/Paul Boratko also has a 4l differential in black.

Now hold up here, I discovered something interesting. Lego uses a really weird measure for the torque of the XL motor, something I have never seen before: mNm. I presume this stands for milli-Newton-meter, which would actually be Newton-Millimeter. Therefore, going by what they say, XL motors produce 90.4 Newton-Millimeters, or 9.04 Ncm/Newton-Centimeters of torque. That is actually far more in line with what Philo measured, but not for stalled torque. He himself noted that the stalled torque measurement was very imprecise. So, where does that leave us? That leaves us with Philo stating that the Power Functions XL motor produces 14.5 Ncm of torque, and drawing 550 milliamps, and Lego stating that the XL motor produces 9.04 Ncm of torque, and drawing 600 milliamps of current. I can think of a few possibilities to explain this discrepancy, which are as follows: Lego is being conservative with their estimates. Philo's test was not as accurate as Lego's Lego used a bad sample Philo used an unusually good sample. This may sound crazy, but might Lego have lowered the torque of the XL motors? In order to test this, one would have to find an old sample, from an MISB 8275, or 8258, and compare that motor with a new one, from 42030. I must say, you would think that Lego, a massive corporation, would have access to some kind of industrial torque sensor to test their motors, but I dunno.

I've got this roughly figured out, and made in Lego Digital Designer. The propeller is the only thing that needs replacing. I've also got a link to the .lxf file if you have Lego Digital Designer: http://www.brickshelf.com/gallery/saberwing2/Ideas/8855boxermod.lxf

Well, aside from the scale, obviously, there probably is not that much difference. Both 8110 & 9398 have live axle suspension, using torque tubes instead of links. I'm not quite sure what the Arocs will use, but I think it will be some kind of live axle.

I like it, but I agree about the very rear section behind the rear wheels. Also, the orange liftarms as turn signals are really distracting, maybe you could use some Plate,1x2 modified with pin hole, and some translucent orange tiles. I say use this because no other type of mount will fit in that kind of space.

Folks, believe it or not, our favorite Lego theme turns 40 in 2017! Since 1977, Technic has been the most challenging and interesting models in the Lego lineup, and I think that Lego should celebrate the line's 40th birthday. So, what do you think they should do? Here are my ideas: Either in late 2015, or early 2016, Lego initiates a new competition: Technic 40th Birthday Present! It would be sort of like the challenge with the 9398 crawler that produced the 41999, but different. The rules would be somewhat simple: design a creation with ~2500 parts, based on any Technic set from the past 40 years, and both the votes of the fans and the design team would determine a winner. In addition, there would be a couple of different new colors and new parts options, to introduce some new parts or colors into the Technic lineup. The above would be the best case scenario, but there are other options. For instance, a voting contest that would have a full catalog of all Technic sets, except for some of the more recent ones, and the ones with the most votes would be the ones that get modern remakes, and form the Technic lineup for 2017. Or, the above, but the most popular set would be the flagship of 2017. Or, as a final option, a new part design competition. I'd really like for there to be some sort of competition or fan involvement, but if that were not going to happen, I'd either like to see updated Technic figures or some remakes of interesting sets, like a new, true 8880 successor, or an upgraded version of 8480. What do you guys think?

Another thing is that they have not been included in a set in a while, making them available only on the secondary market. Also, a lot of people have griped about not using red #3 connectors in 42029, and not using yellow ones in this year's dump truck. Why do you think that is?

I'd have to agree on the stuff being too expensive on the secondary market, but going by the actual question, I feel as if Lego hasn't gotten any more expensive. Prices have actually been relatively constant, but quality of sets has gone up dramatically. C'mon, why gripe about price, when you can gripe about the lack of availability of parts in certain colors, or any of the innumerable other things we fans gripe about?

Yeah, but what works for Lego cars and what works for real cars are very different things. Most Lego cars do not need any kind of advanced suspension geometry, or brakes, for that matter. Also, like Sariel said, I have never seen a Lego supercar encounter a slip or odd traction situation that would require a limited slip differential.

I personally don't care about the big box thing, I've had sets that had larger amounts of empty space in the box, and box size has overall gotten smaller. The only thing I don't like is that big boxes are harder to store, as a collector. Oddly, I feel that large sets that come in smaller, but thicker, boxes are more impressive. It feels as if you get more that way. P.S. All the errors in this thread are a little annoying, like using waist instead of waste, and to instead of too.

I'm fairly certain that in order to have any kind of torque bias, there needs to be a difference in the gearing of the axles on either side of a differential. Also, this differential is not strong at all, and will break apart as soon as it locks up. I speak from personal knowledge, as I have build this particular design, and have tested it. If you want a limited slip differential, Thirdwigg has build some in his trial trucks. Kenworth T55 Driveline by thirdwigg, on Flickr However, from my experience, differentials in most kinds of Lego trial trucks are rather counterproductive, even if they are limited slip.

No, it will not. Parts only crack like this from stress. If you are opening a mint set, all parts should be intact.

A tower crane with a grab is something very unusual, but I've noticed something else. There is not, apparently, any system to move the trolly by rope, although that would be a fairly easy modification, and the b model has extensible tracks. I think that the chassis for the A and B models should actually be reversed, so the A model has extensible tracks, and the B motorized movement.

Could you show a picture of it? and a picture of the stud, which should say Lego? That would help us tell you what you have. Also, many thanks for the information on the updated Blacktron stuff. Also, I'm wondering if the parts on that Ninjago dragon are glow in the dark, or just spring green.

Great find, looks like it a 4x2 Arocs with a flatbed trailer and crane. Although, the crane looks very similar to the A model version, although it's unclear as to whether it has grabbers, or some other kind of end effector.
