Have you set the channels on the remote and the IR receiver on the same value? On the IR receiver there is an orange switch you can move up and down in four positions. On the remote there is a similar orange switch. They need to be both in the same position.

I have no idea why you would call this an epic fail... From what I see (albeit from a rosy perspective of being on a camping in the sunshine enjoying a good local Belgian beer), I see a well functioning, well endowed (functionwise), well executed model. I think there are a lot of people on this forum that would love to be able to pull this kind of model of.

Great contraption! How do you control the two different flight modes? Do you just stop at the right moment or do you have two different controls (or a switch?)? As others said, just when you think you've seen it all...

Still too hot in the shed I suppose? That might have something relation to that warped plate BTW... Looking at the last photo I just love the way the panel of the door comes together with the front-corner panel. I always felt this truck was inspired by the Scania trucks of that year. And I wondered why Uwe didn't invert the 3x7 panels at the front, because they would then give the natural curved line downwards (which is now done with stickers). But seeing how the two panels come together I finally understand his design decision. It is really a joy to watch this build coming together. Together with the 8043 this build ranks among the highest ones I know. In fact, I think these models are at an optimum in terms of parts vs functions vs size (this one even more so than the 8043). I'll be getting the 42082 later (when the price is dropped), but I am somewhat daunted by the prospect of building (and disassembling and sorting) it. The latest massive models (Chiron, BWE, maybe even the Mercedes truck) are for me beyond the pleasure point. So, back to this build, forgive me for my rant on the ever increasing sizes of the models, I hope you will continue to take pictures and photos while you are progressing glacially through this build.

Wow, just wow. That is a seriously good looking car, but knowing it is a B-model brings it to another level. Very well done

Current part count is ~7400 parts. The turntable is indeed not functioning properly. I have to see if I can redesign it such that the rollerbearing can work more smoothly. That might help in getting it to work.

It is quite an asymmetric model: 5 left, 6 right small red panels only 1 5x7 curved red panel 3 left 3x5 red panels 1 right 3x7 red panel I've never seen so many unmatched panels in one set ever.

I haven't decided yet how to optimize the parts in this model. I have to choose between a couple approaches: 1) Pick a few sets and optimize to use as many of the parts of these sets as possible (the Mack & Hovercraft could be excellent parts donors). This will mean that the build becomes more difficult because look-alike parts (like 13L and 11L beams will not be colourcoded). 2) Minimize the number of unique part-colour combinations. This is the approach I have chosen now, only ~250 unique parts are needed now and most of them are quite common I think. 3) Optimize to the best looking colours irrespective of colourcoding. This would also mean that for instance the colour axles on the outriggers would become black or grey. Of course this also runs the risk of using rare parts. I am looking forward to your LR...

I think so. But it is a bit of a balancing act. The most important thing for lifting heavy stuff is making sure that the crane doesn't topple over. Strengthwise I think it can handle really a lot. From the top of my head (for just the boom): 28x white 3x11 curved 24x black 3x11 curved 4x black 3x11 curved with 10 pinholes 14x black 5x11 6x white 5x11 14x black 3x11 For the whole model you'll need additional: 21x white 5x11 1x DBG 5x11

Summerholidays are about to start in the Netherlands

Yes that is the goal. I actually made attachment points for a latticebeam on top of the telescopic beams, so maybe I will add that too Currently I am around 7400 pieces Now that the Testarossa is done I found my rhythm again. I might even find a lost hour for another project before the holidays

Hi, Time for another update. I finished a first version of the boom (and I redesigned quite a few bits in the carrier). I did a first testdrive in my garden to see whether the whole would still be manageable or whether it would collapse due to it's own weight. To my relief I was able to erect and extend the boom and then let is stand without any help: The thing is massive! It is difficult to judge it's scale from the photo, but when you stand next to it you feel dwarved. The numbers are also getting insane. The boom alone uses 90 11-stud long panels. The whole model has >1000 black friction pins (I actually start to see the bottom of my black pin bin which I'd never thought I'd ever see again). I used 284 gears and 900 axles so far. I estimate that I use 50 m of rope. The weight of the boom is so big that my brickbuilt cilinders do not stand a change of lifting it, so I added a rope and pully system to help lifting it. The construction is completely form-locked, but even then it is being pried apart when lifting the boom, so I will have to add more reinforcements to it. Even though the photo might suggest that the design is finished, it is not. There is quite a list of things that I want to change still: The rope for lifting the boom and the extention of the cilinders need to go to the same group of RC operations (if you remember there are 4 sets of 3 functions each in the superstructure) so that it is possible to drive the cilinders and the ropes at the same time. A driving mechanism for extending the inner sections needs to be made that is strong enough (at least it is self braking now) The structure where the pulleys in the rear are connected to needs to be strengthened (there are even some form-locked constructions that are being pried apart) The stabilizer arms need to lift further upwards The small LA’s in the stabilizer arms need to be replaced with big LA’s (that will bring the total amount of big LA’s in this model to 12) The rope for the hook needs to be properly guided along the boom The legs to put the boom on when moving the boom from the carrier to a transport wagon need to be designed and added A couple of functions do not work properly: The rotation of the superstructure is only possible with manual assistance The switching between the functions in the superstructure are driven too fast, meaning it is a hit and hope approach in changing functions So still a lot of work ahead... For those who are interested: work on the instructions has started. As a final picture, the model in it's road going configuration: Leg godt, Jeroen

Great little creation I use LDCAD for my digital modeling. It is amazingly well suited for handling flexible elements (ropes, pneumatic hoses, flexaxles, chains, electric wires, rubberbands, springs, etc. etc.). The whole package has a bit of a steep learning curve, but once you get the hang of it you'll never go back. It is based around the LDRAW core, so you can just import your LDRAW models.

When you turn the wheels you have to either block one wheel and turn the other or turn both wheels in the same direction. Did you do that? If you only turn one wheel you'll see the other wheel turning in the other direction and no gears will rotate (except for the 12T gears in the differential).

Good progress! Seeing the photos I remember that the new 16T gears had a really low clutching power at the time. I think there are even parts in the construction where an axle was protruding solely for the reason to put an extra bush on it to prevent the gear from sliding of the axle. However when I look at your photos there seems to be a 16T gear that is attached to the end of an axle (at the rear of the outrigger assy) ready to fall off. Do my memories fail me, will this gear be fixed in another way or where only a few 16T gears secured with an extra bush?

First of all, thank you for all the positive replies. I really appreciate this. As I wrote this car has been fighting me throughout the designprocess, so in the end I guess I could only see what was wrong with it instead of what was right with it. So thanks for pointing me to the good bits Yep, another struggle area. At the 1:10 scale lights somehow have the tendency to need a 1.5 stud diameter or height. It always is a compromise. Yep again. I must say I missed the step when refining this area. I had loads of issues with the area above the wheels (which might surprise you given the simple stacked beams that are used there now). This was mainly because I at first had placed the vertical panels at a slight angle which made the bodywork connection between the two parts even more difficult. I guess I was so happy when I finally sorted this area out that I forgot to check at the topside... I'll keep that in mind for a next Ferrari. too much praise really, you won't have superlatives left if I would top this one You got me there. I mirrored a couple of photos to make it look like a continental car (ie steering on the right) so that it feels more natural to most people. I should have known better than to try to trick you lot Gearswitching is done with the standard red LEGO catchover between (just in front) of the seats. The steering is only operated with the steeringwheel. I actually had to use a chain to connect the steeringwheel to the steeringaxle at the gearrack. The headlights are operated with a push/pull switch below the dashboard in front of the passenger seat. In the close-up picture of the seats you can just see a black pin-with-two-axles-perpendicular; that is the switch. No video I'm afraid. The car is already on it's way to it's new owner. Also no underside pictures, since the car is already shipped. I always want to get critique. It always hurts after spending so much time on a design, but after that wears off I usually learn from it and can improve the next one. No it is 1:10 scale Yes, I finalized the carrier so making of the instructions has started. I am nearly done with designing the boom (but holidays are fast approaching), so I can testbuild that. If that turns out well it is ' just' a matter of finishing all the instructions. You will have to bear with me for a bit longer because the current partcount is around 7400 parts, so it will take some time to finish these instructions... Once again, thank you all for all the reactions. It is very much appreciated. Leg godt, Jeroen

Wow, that is massive! I love the rugged looks of it. Do you have more information on the suspension? Do the outriggers have a knee-mechanism, that formlocks them when they are down? Or do the gears still bear the weight when they are extended?

Hi, I'd like to present to you my latest commissioned MOC, the Ferrari Testarossa: This car is something special for me for two reasons. First of all this is one of the first supercars that I remember seeing as a kid. It made a lasting impression to me. Secondly because this car has been fighting me during almost the entire design process. I never struggled this much with the design of a LEGO model. The start was promising, designing the rear suspension and 5+R manual gearbox went smooth, but after that smooth start things just never seemed to work out. For the doors I quickly decided I wanted to use the long Ninjago blades for the side fins: But then I made the doors too long, then too short and don't get me started on the top part of the door. I must have made at least twenty different designs to try to capture the lines of the real car. This is the best I could come up with without completely resorting to systembricks On the positive side, the chairs went really smooth. Normally chairs are my pain in the megablocks, but this time they came together in a jiff. They are adjustable and I used the axles of the gearbox as guides for the chair. This way I could keep the interior really flat & low. I am also quite pleased with the popup headlights even though the mechanism to operate it is not as nice as the one I used in the Ferrari 308: If you look closely you can see there is a small curve in the hood. The three panels are held together with two elastic bands at the other side. I use pins-with-axle-without-friction between the panels to create enough slack to get a slight angle between the panels. Before I forget, the list with features: – Independent suspension on all wheels – Steering with Ackerman geometry and working steeringwheel – pop-up headlights with a – 5+R manual gearbox – Flat V12 fake engine – openable hood, doors, trunk – adjsutable seats – detailed engine bay & interior (with working glovebox ) As always, comments, questions and constructive criticism are highly welcomed Leg godt, Jeroen

For me the size of the new sets is off-putting. Even though I am designing massive models myself I use that extra space for extra functionality. Having to build for 9 hours to build a car that steers, drives and has a gearbox feels for me as a too big investment in time (not to mention another 5 hours to take it apart and sort everything away). So far I have always built every (first copy of a) model that I bought, but I am seriously considering not to build the Chiron or the crane (while I will still buy them for the parts). So from a purely economical standpoint LEGO is still doing the right thing for me because I will keep purchasing the new models for the parts, but the joy is less with these huge-size, function-poor models. I'd rather spend my time on designing compact & smaller scale models that are packed with features. For me the pinnacle of this in the last years was the Claas, that is such an intricate model packed with exciting functions. I also like the challenge of a 1:10 scale car better than a 1:8 scale car. The LEGO system is not suited for that scale I think. Beams are too short, which means you need a lot of bracing & double width beams to keep it rigid. I read that the Chiron feels quite stiff, but the underside of the car is not looking elegant at all from an engineering point of view. At some point I count 6 stacked beams in the floor... Of course it also depends on the designer. Uwe is a master in the economic use of parts, so his models are usually much lighter in terms of structural elements without sacrificing stiffness or rigidity. This gives a lot of room for extra functionality (see for instance the build-thread of @grum64 of the 8258 as a perfect example of this). Even the loathed 42070 is a beauty from an engineering standpoint I think. I actually really enjoyed that build. It uses the parts so efficiently and still packs a load of functions in it. Too bad the pricetag was so high. So I hope the trend will reverse towards more Claas like models, maybe even larger models at that scale.

Wow, beautiful I especially like the front blade, such smooth curves

A great build again. Incredible amount of functions in such a small space.

That's what I meant. It really is a pity that they didn't take the learning from the 42009.

Unfortunately the gears for the LA's are again not mounted correctly (just like on the 42009)... They are mounted in a way that when the boom lifts most load will transfer to one LA. And it looks like it will not be easy to fix this time.

Oh this will be a joy to follow again. I am really looking forward to this one. It is the set that finally convinced me that studless building was the way to go. That gearselector mechanism is so wonderfully complex with great part usages, that is just brilliant. Keep those updates coming

Very nice model. I especially like the shaping of the trunk with the retractable spoiler. The roof and bonnet are a bit flat though, have you considered using the 3x13 curved panels? I don't know the real car very well, but the A-pillars do look a bit steep, or is that in the real world as well? The car looks like it will be a lot of fun to drive with, so you captured that spirit very well I think
