Thanks! Thank you! Yes, totally agree. I guess now that I'm happy enough to post about it, I can bricklink a few parts to improve on the details.. I've been doing with what I have, which is limited. The essential comes from 42098's blue car itself.. Thanks! Well, the geometry of the front axle is not perfect, but it works and is robust. I may take the time to model it since you're interested! My favourite twist also! It's bad; the part is under constraint. Yet it flows so much better like that! And honestly, it's quite a light flex: the original shape should not be altered unless they remain like this for years. The triangles supporting them are strong: the panels do not pop out easily: the car can be manipulated without having to take care bout that detail, so I deemed it acceptable. Plus it shows I'm a rebel. Which is kinda part of the fun too.

TC18 is behind. But it left me with kind of a bitter taste, so I wanted to build some more. I had very few car-specific parts at the time, namely no wheel arches and only one, 4-studs wide differential. I got 42098 very late in the contest, a bit too late to start over, so I submitted my little Hot Rod as is. And it ended up not getting the love I thought it deserved. So I took apart 42098's blue car and started a new TC18 build, just for fun. I wanted at least the same features as my TC18 entry; steering, full suspension, fake engine, gearbox, doors, etc. this time with more realistic looks. This is what I ended up with: I'm really happy with how all features work; the wheels never get to touch the arches, there's still a bit of ground clearance when the suspensions are all the way down, everything moves easily yet the structure is quite sturdy. It's not designed after an actual model, but the inspiration is 70's Japanese rally cars, hence the consequent suspension travel. Bonus; it even fits the lower deck of 42098! Thanks for watching! [Edit]: Latest updates here.

Very nice one! A cow would be a nice touch indeed: in Valais, we say "T'as où les vaches?" (Where do you have the cows?) to mean "Where are you from?" But for me, a Swiss guy that lives next to Valais, the most disturbing thing is that it's not built on a slope. Chalets are very seldomly built on a flat ground

Giant tractor
1980SomethingSpaceGuy replied to howitzer's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I for one would second @Sariel on this; I much prefer a good slap in the face pointing the flaws in my build than a deadly silence that leaves me with the illusion of having devised something decent. And the latter tends to be common here, which I deplore. We're all adults; we can take a bit of criticism. What would be unacceptable is to comment negatively with absolutely no clue or details and never visit the thread again. It's not what happened. And I couldn't agree more with @Maaboo35: tractors don't have much suspension, if at all. @howitzer : maybe you could keep it simple for now, and continue building the rest of that giant tractor? -

What a nice place! Thanks for sharing Clive! -
She's got the looks, good job! It took a rather System turn, but I guess it's fair. For the a-pillars, you could have used a good ol' black 3L axle and 2 of those : But of course keeping them dark azure is nice.

I'll drink to that then! -
[TC18] Hot Rodster
1980SomethingSpaceGuy replied to agrof's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I've read all posts in this topic. I must have missed the part where you say that the engine is not connected. As a matter of fact, I even missed that detail when I quickly watched across the instructions the day you published them. I had to reopen the file and take a closer look. Maybe because I just couldn't build something like that myself; I didn't expect it at all. I'm not saying it's wrong or anything. Seen the praise you got, it certainly was the best thing to do. I for one would rather concede on style for better features, or on realistic looks to avoid flimsy system parts (not the case with this one of course) and stay on the Technic side. But my approach appears to be far less popular. So hats off to you! -

Damn, that's right! There's only a bevel gear to like.. spin the motor with the finger? -
27. Miss Butterfly's Hot Rod A manly featured ride with a feminine touch. Full independent suspension Working steering wheel RWD with differential 2-speed gearbox with working cockpit lever lever 2-cylinders classic fake engine Openable doors and engine bay Structure is very strong, all features work flawlessly. A squeeze horn is equipped to rally votes flying by.

A lot of the answers you're looking for are here, I think: That is: A ski lift (that's how we call them here in Switzerland) uses a cable under tension. You'll either need heavy weights or a strong structure to hold both stations in place. Luckily, your setup should allow for a decent Technic superstructure under the white plates figuring the snow slope. By increasing the tension, you'll reduce the slip on the driven wheel. It appears you'd rather use wheels with tyres (and rely on their grip) than just rims with added rubber tape or others. Using a stack of 2 motorcycle wheels create a nice groove that holds the cable in place, but the grooves of a single motocross tyre may work in your case too. Using non Lego for the cable is usually deemed acceptable. A bit of elasticity is welcome for the purpose, and hard to find and maintain with official parts. Then, your setup matches the simplest scheme; horizontal end stations, 2 angles, slope in between, no intermediate pylon: Angles should be dealt with at least 4 wheels, on levers by pair. As in: The green spot and the points where the orange meets the red are articulated. This provides the necessary smoothness for the chairs cable linkage system to go through. For the latter, catching the cable between 3 half bushes as in seems to work well. Good luck with your build! Keep us updated!

No. If you claim a C model with no additional parts required but in fact some additional parts are required, you're in fault. Not the buyer. And quite frankly, I don't get the point in designing exotic suspension systems with the parts from the original model if you use extra parts elsewhere: just use shocks as extra parts, et voilà...

Wtf? Mentioning Sariel's good, actually understanding what it's about is better.. From the motor on, we have: 12t on 12t: 1:1, 20t on 12t: 5/3=1:1.67, 20 on 28(diff.): 5/7=1:0.714, total=5/3 * 5/7 = 25/21 = 1:1.19. And if we care about vehicle speed, the size of the wheels is important too. The wheels of the vehicle in your clip are different from mine. I'm pretty sure the gearing is different too, since it appears to have been shot beforehand. Moreover, it's hard to have any idea of what speed the vehicle can go since it's basically going to and fro. And let's not talk about the potato quality... All in all, I really don't know what you're trying to prove here. If your point is 2L motors should be enough to achieve the required velocity for a balistic trajectory over 42098, I'd say most likely yes, but it remains to be demonstrated. My point is this topic's vehicle won't do it as is, nor with a slight gear swap.
