Great model, and beautifully photographed. The windows do look a bit high, but when searching for pictures I saw the Pajero junior also has a pretty high body profile. Very smart drivetrain

Very interesting build so far. Looking forward to see it in action. Those quartercircles are ideal for the arms , but I don't know yet whether I am sold on all the system and the few 3rd party parts... But I'll hold my horses until I see the final product.

Thanks The center column shifter is the D-N-R switch. I haven't decided yet on the sequential shifter. I will at least have some HoG shifter (a gear, or a lever) and maybe I will add paddleshifters as well. The latter will depend on the space near the steeringcolumn, which depends on the answer to your second question... For the brake control I do not have a clear picture in my head yet. Having a brakepedal is more authentic, but in terms of play-value pretty shitty because of the location. I am not sure if one stroke of a minipump is enough to engage the brakes, definitely going to test that though, because that would be an elegant solution. I like the idea of using the volume of the pump to increase the pressure in the system. If a minipump is too small I can also try the big pump (it probably will become a HoG brake then) The alternative is indeed an airtank and a switch. But the airtanks are rare, bulky and expensive and the switch has a lot of friction which means it will be difficult to let it return automatically, so that is not my preferred solution I am looking forward to your model, very interested what you come up with in terms of bodywork. In terms of inspiration I have three styles that I am toying with in my head: The tough, masculine lines of the Audi R8, the angled, sharp surfaces of the Lamborghini Aventador or the curved, open bodywork of the McLaren Senna. Very different styles... so choices are needed at some point

The brakes are finished as they are now I think. I have tried to incorporate the rubber double connector, but I couldn't find the space for it. I may add some parts for aesthetics though, as it is now you can see the red 5L beam through the spokes, but since it is sideways you can't really see the colour pop out.

You are right, I mixed up the terms (again). The steering has positive caster, not camber Kingpin inclination would make the steeringsetup even more complicated (read less robust). The steering point is still within the wheel (albeit not at the center), so adding kingpin inclination would not help too much for minimizing the space around the wheels when steered.

I have build it in the flesh and it works smoothly (especially without wheels, I still have to test it with wheels and the added friction that that will give) In 4th gear you will get crabsteering, in reverse the rear steering is locked, so you have just normal 2 wheel steering. When in neutral the front wheels steer normally and the rear wheel steer at half the amplitude of the gear-dependent steering (if that makes any sense). But since you normally can't drive a car in neutral I don't bother about it. The steering angle is not too brilliant due to the positive camber. These suspension setups with positive camber and a gearrack behind the wheels are always a fight between sufficiently small travel, sufficiently large steeringlock, form-locked wishbones and an as symmetric as possible structure to lead the suspensionforces through. The gearrack in front of the frontwheels is actually part of the gear-dependent steeringmode selector (in fact almost everything in front of the front wheels is the gear dependent steeringmode selector. The pneumatic brakes fit nicely in the wheel, they brake on the sprocketwheels, not on the inside of the wheel. I really want to use dark azure for the bodywork now that almost all the panels are available. But, not having any flexaxles will likely mean that I will use a secondary colour as well. Maybe a Chiron-like blue/black/silver scheme... As for styling I really want to try to have a more open styling this time, with holes and gaps to show the inner workings, but usually I start adding panels together and before I know it I have some large closed surfaces and then it becomes tempting to close everything

The frame around the engine is still preliminary, I am not happy with it yet (it lacks 'efficiency' so to say). But if I add the convertible roof the engine will be mostly buried under the roof and the lid I think, so in that sense the frame doesn't matter too much. Yes, I finally came up with a design that fits in the Porsche rims without using the standard LEGO hub.

The steering mechanisms would not change, but it would shift from opposite to crab in smaller incremental steps (which actually could be an argument to limit the number of gears, otherwise the effect might be too subtle from gear to gear) The AMG GT R was in a 1:10 scale, so dimensions are really different. Furthermore in this model the D-N-R switch also influences the steering, in my AMG GT-R it did not.

Thanks again all for the positive comments. The knob of the roofmechanism is disguised as one of the engine air intakes. You can reach them when the trunk is opened. For the video I have used a long axle instead so that only the car is visible. Not a 1:10 scale model, but I am now working on a 1:8 scale model that I plan to make instructions for (see my WIP topic I just started ).

Hi, I have been working on a new 1:8 scale supercar, codename Silvestros. Here is a first picture of the chassis: So far it has the following features: 4-wheel drive 4-wheel steering (with positive camber caster & Ackerman geometry) 4-wheel independent pushrod suspension 4D+N+R sequential gearbox pneumatic diskbrakes on all wheels V10 fake engine The steering is dependent on the gear you are in: R : front wheel steering 1: the wheels steer against each other 4: crabsteering 2-3: proportionally in between Here is a view from the underside where you can see the linkages needed to control the steering of the wheels: I plan to include the following features as well: fancy doors (opening upwards or backwards or whatever as long as it is not regular ) convertible roof maybe adjustable seats What I would like your opinion on is the gearbox. As it is now it is a small 4D+N+R gearbox. The good thing about that is that it fits nicely below the low mounted engine (which should give some room for the roof later on) and leaves quite some space between the seats and the rearwheels for mechanisms for the doors, the seats and the . The bad thing of course is that it is only a 4-speed gearbox, which is a bit lame for a supercar... So what do you prefer? An 8D+N+R gearbox at the expense of some of the other functionality or keep it as is and fill the space with the other mechanisms? I am not going to model this car after an existing car, which should give me some freedom with the styling. And this is not going to be an exclusive model or anything, just a regular buildinginstructions for a small fee kind of project. Leg godt, Jeroen

Thanks for all the positive comments, that is much appreciated. The model is already on it's way to my customer, so I can't make any more photos. I can try to explain the mechanism in words: It are basically two rotating liftarms that drive the roof and the lid. The are geared 1:3, so the driving linkage of the roof turns 1 quarter and the driving linkage of the lid turns 3-quarter circle. When the linkage of the lid is at 6 o'clock the lid is closed. When it is at 9 o'clock (it turns counter clockwise) the lid is closed again. At about half two the lid is at it's maximum opened position. The linkage of the roof is tuned in phase such that the roof is closest to the lid when the lid is at it's most open position. It all just goes. If the roof would come up a bit earlier, or later it would collide with the lid. Thx. You can always send me a PM Thanks, I think >80% of the Ferrari's sold are red, so I guess I'll be building red Ferrari's for some time . The second part will come, I just need to shoot one more scene and then I am done. I'm curious about your little project... Thanks, that means a lot coming from you. I'm still interested in your view. Would you mind elaborating (in PM if you prefer), as nice as all the positive comments are, critique is the only way to get better. Don't worry, I am not some kind of superhuman LEGO builder. I am not building sequential, but I usualy work on two or three models at the same time. For various reasons these models were all finished roughly at the same time. Thanks again for all the positive comments. Jeroen

Hi, I would like to present my latest commissioned MOC, the Ferrari 458 Spider: It is 1:10 scale replica of this iconic Ferrari. It has the usual features (independent suspension, openable doors, fake V8 engine, steering, etc.) and a few more noteable functions: A 4-speed sequential gearbox (thanks to @Didumos69 for inspiration of the stepper mechanism) A convertible roof Here is a video showcasing the functions: It was a real pleasure to design and build this car. Especially the rear end is a maze of functions with the mechanism for the roof, the gearbox, the rear suspension and the fake engine all cramped into that little space. And of course I also still had to get some beams across as well to give the model enough rigidity to make the suspension useful. I have rebuild that section dozens of times until it suddenly all snapped into place. The stickers were made by @jaaptechnic, including a few you can't see on the photos . Comments and questions are appreciated. Leg godt, Jeroen

You're welcome. I'll take a look at the head when I am back in town (which will be in a week or so), but I do not expect to be able to improve much without sacrificing the sturdiness of the connection of the blades TBH.

Oh wow I love that curvy flexaxle below the rotor, it indeed gives a good dynamic. I have never built someone else's MOC, but I am very tempted to build this one. It ticks all my boxes for a great Technic set. I kind of liked the spindly appearance of the previous rotorhead (although I disliked the big white round plate on top). The new rotorhead looks a bit large in diameter...

As sir von Lego said: not often seen in the wild + a brand that is already in the racer theme + abundance of dark azure panels this year --> 42083 = Bugatti Chiron?

Incredible creation! I love the built-in load measurement system, very clever The mass balance looks almost perfect, did you have to play with that when you lifted heavy objects? Or has the crane so much mass by itself that the added load of a chair is still relatively small? Definitely looking forward to the turntable construction, that is working so smooth.

Even though I at first also was convinced it was a 3x7 dogframe, I am now swayed to the other camp: 1) the 11.5 double bent liftarm at the front is not sticking out, hence it must be oriented lengthwise, hence the beam is 5 studs high 2) The 3x11 curved panels do look quite elongated in the rear, so there is definitively some distortion going on 3) It makes less sense to have a similar frame in a different dimension 4) For a two stage boom 5L thick enough, there is not really a need to go to 7L 5) The distortion also would explain the 3x4 T-piece being just a 3x3 T-piece (which is introduced in red in the fire-truck of H1, right?)

My bad, you're right

v2 it says clearly...

The Fork lift has Mk IV on it I think... But the crane also has something like MK or OK on it...

I second the coherence argument. It is one of the things I also admire a lot in models. I am not sure the panel style was 'kept' for the last ten years. I feel that this has evolved towards more and more paneling and less flexaxles and less suggestions of form. I do hope we will get a next step in that evolution which will bring (back) that balance between looks and functionality.

Even though I tend to make quite heavily paneled models myself I do think I like semi transparent models better. It has something to do with capturing the essence of a model if you can use a minimal set of elements to convey it's shape. I have a similar feeling towards the inner structure by the way. That is why I like the 42070 over the 42069. The minimalistic design of the 42070 sparks more joy in me than the dense, but (to my opinion) cluttered design of the 42069 (which is offset by the price difference, but if that difference had not been there I think more people would have liked the 42070). @Lox Lego: I agree wholeheartily with your peek-a-boo comment. Seeing that something incredibly complex is going on inside, but not being able to distinguish what it is really adds to the excitement I think. Too open and there is no secret, too closed up and you don't even know it is there.

It's a significant part of my life now that I try make a living out of it Want, yes, but as it looks now it will be warmer than Easter again... Don't think so, but don't feel sorry for me, my LEGO room overspilled into a second room this year... Make some videos and start a non-commissioned project (still doubting between a F1 race car and a self-designed 1:8 supercar, so preferences are welcome) Hmm... Having built a lot in red/white/black the past year I actually look forward to start making some stuff in dark azure now that it is becoming more available. I think it is a really rich colour so I'd like to give it a try.

second that

Wow, I saw this model at TLCB earlier and it is indeed a masterpiece. It is so well proportioned and to have so many functions inside is just wonderfull.
