    Wow! This one is really true to the spirit of the competition. Especially the width change of the chassis is a great bonus. I know you prefer building in dark grey, but adding some colour could make this entry even better. I hope you get all the transformations to work properly.
  2. Impressive start. Out of curiosity: did you already get yourself a Titanic to see what LEGO has come up with?

    [WIP] Aston Martin Valkyrie

    Thanks for all the feedback. There will be some extra bodywork between the front fender and the bonnet, but there will be a hole there through which you can see the suspension arms, just like the real thing. Yeah I have a pretty big catalogue in my head that I (subconsciously) use during the designprocess. The headlights for instance are made of a diamond from the RockRaiders series and a headgear crown with 4 tall spikes that was used in an obscure Lord of the Rings set in 2014. Having said that, I do spend also a lot of time browsing through bricklink to find parts that have the right shape (in the right colour). It would be great to have some SW that can search by shape though... The funny thing is that positioning the panels on this car so far has been relatively straight forward. I usually need to position panels rotated around at least two axis, but here most panels are only rotated along one axis (or even just straight). My approach is always to first try to position the panel in the position I want it to have (using ball joints, illegal techniques and what not to keep it in place) and then work on the structure to fix it in place. That structure then can be refined until it is small enough to be out of sight, strong enough to handle the car and preferably doesn't introduce too many new parts. I recognize the A-pillar comment. It is indeed a bit too round. I'll play around with some #4 connectors to get a bit sharper corner at the top. Alternative could be to use flexaxles for looks and some structure behind it for strength. Too bad the A-pillars are black. Red flexaxles against a black structure work much better than black on black I think.

    Time for another update. I've been working on this almost all of the time I have to work with LEGO, but progress is slow. Not in a bad way slow, as in I have difficulties with finding the energy to work on it, but in a good way slow, as you would enjoy reading a good book. The car sort of demands to get every detail right. So it is a continuous urge to push the design further. So let's start with an overview shot: I'd say the general shape is starting to come together. There are still a lot of details to work on (like the doors, the interior, etc.), but the basics are in. I have an 8D+N+R gearbox, a V12 and pushrod suspension on both ends that is stiff enough to support the weight of the car, whilst compact enough to fit in that ultratight bodywork. The central tub is more boatlike then before with huge sidepods for the airintakes for the motor. The front is starting to take shape as well. The challenge here is to minimize the clutter, while keeping the shape correct. The little triangle in front of the window can be opened (albeit there is almost no space below it to put anything in): The headlights are one of those details that have cost me already several hours to design. And I am still not happy with them, so some more redesigns will follow. But the detail that has taken by far the most time so far are those pesky rearlights: The current compromise is the omit the middle row of lights. This allows for a very clean and compact design. You can also see the big diffusor shape. Furthermore you can see right through till the front with only the suspension arms of the front wheel blocking your sight (of course this is partly due to the fact that the big airguide behind the frontwheel is still missing). Comments, critique and advice is welcome as always.
  5. Reducing the amount of universal joints will definitely reduce the slack in the system. I would also try to replace any remaining universal joints with CV joints as these have less slack.
  6. I really like those headlights , using the 13x3 panel is a stroke of genius. The airintakes I am less sold on. What happens if you turn the small panel at the bottom of the side intake 90 degrees (or replace it with a combination of #1 connectors and axle-joiners? That downward slope to the middle somehow feels wrong to me. The front airintake could maybe benefit from a continuous orange line at the top. Now there is a 2 stud gap between the hood and the headlight. Adding an orange #1 connector or 2L axle-joiner will make that area more continuous.
  7. Always a tough decision to make when you already have so much invested in a build. I usually switch between digital and physical versions when I have to make these big overhauls, for me that somehow feels less painful. Keep going

    Wow, @imvanya @technicmath really creative solutions! Many thanks for this. The horizontal spacing has to be increased to 1.5 studs between the lights, but I think that is for both solutions not a fundamental issue.

    All panels are hard to attach on this one

    For now I plan to use a 5x7 panel. That is currently the best compromise I can think of.

    That is meeting the brief almost perfectly. It is a bit long when using spear tips instead of lollipops, but other than that it is as good as it gets. The price of these lollipops is indeed crazy as @howitzer also mentioned. I'll first see if it fits lengthwise before anything else.

    Thanks for thinking along. This has a better height, but it misses the staggered placement of the lights from left to right. I've put the rear lights aside for a while myself. Usually it helps me to switch to another problem to get insights for the problem at hand. So I started working on the chassis. I think I finally figured out how all the ducts are running next to the tub. There are actually two ducts on top of each other I think. The lower one runs all the way to the back where it spreads out to form this massive diffusor. On top of that is another duct to get more air to the motor. In LEGO terms that second duct is basically free construction space as there won't be any air flowing into engine. So was able to use that space to make some longitudinal and vertical bracing. This is my fourth version of the chassis: The central tub is pretty much braced from all sides now. One thing I am still not happy with is the bracing of the vertical column below the roof (I see that I even forgot to connect it at the bottom ), but ideally it would also connect somewhere at half height to the big frames behind it. Unfortunately the knobgears for the gear selection are all located there... Next step is to add all the pins to the structure and then build it for real to see how stiff it is. The gearbox sits snugly below the engine. I think I can manage to bring the gear selector axle to the front, but I need a very small stepper mechanism to operate it I am not sure yet how to do that.

    Thanks. It has all the offsets needed, however the spacing vertically is 1 stud now, whereas I am looking for a solution where the vertical spacing is more like half a stud. Ideally it fits in a vertical space of 2 studs including the supporting structure.

    Thanks for the suggestions guys. In the end I chose this one to try an alternative solution: Here is the result after days of tinkering (the lights are 1.5 studs apart horizontally, something like 0.7 studs vertically and they are staggered from left to right, that is just so difficult to make): To be honest I am not too convinced myself. The construction is quite weak, the 3L bars stick out and interfere with the panel above it and the pointy ends of these speartips are a bit too small compared to the real lights. But what do you think? This car has a really long wheelbase of 3.06m. Even the Pagani Huayra has a shorter wheelbase of 2.8 m. I've also started to sketch the upper bodywork:

    As expected, lowering the differential & rear suspension pushrod required a complete redesign of the whole rear area . But, as there was still some free space, it does fit, so I could then work on the esthetics of the rear side. One of the items I definitely want to capture are those nine protruding rear lights: After a day of tinkering I came up with the following solution: The lights are a bit too thick, but I couldn't think of a thinner transparent piece that I could use. If anyone has a suggestion, please let me know. I also was able to create the covering for the exhausts. A bit better visible under this angle: Next steps are rebuilding the gearbox + rear suspension and working on the engine covering.
