He inspires us "grown-ups" too, if that matters

Where does the valve vent? Is it possible to block that hole with some rubber part? Maybe that would help.

Are there more pictures about each car?

What do you mean by risk? Forgetting how it was assembled? If so, just take it apart and make photos during the procedure. Or model it in a CAD program, the chassis doesn't seem too complex to do so.

Thanks for the comments! I'm happy that it's featured on the blog, it was a dream for quite a while.

Yeah, I forgot: More images: http://www.brickshelf.com/cgi-bin/gallery.cgi?f=518493 Here's the WIP thread too: http://www.eurobricks.com/forum/index.php?showtopic=76961&hl=

Hi all! This is the final version of my 1:9 car. Features: -4 wheel drive -3+R transmission with central differential. -steering with Ackermann geometry, working steering wheel and HOG -V12 fake engine -independent suspension on all wheels -Everything can be opened. Length: ~62.5 studs (50 cm) Width without mirrors: ~28 studs (22.5 cm) Height from the ground: 14 cm Part count: ~2100 I uploaded the LDD file too, you can find it here. Remarks about the file: Video: I'd like to thank Kronos for his insight about others' supercars. How heavy they are, how flexible they are etc. it turned out that I'm over-stressing about stiffness and weight, and I could move on and could actually call the model finished.

Your Prado is just awesome. I envy your skills knowing that was your first big supercar. Once I get over my stupid uncomfortable feeling about online paying, I will buy instructions of MOCs (yours too). Probably I won't build them, but would buy the instructions anyway.

Lovely thread.

I call the project finished. I redesigned the chassis, the LDD file is almost complete. Minor changes (mainly color) are still to be made (probably when I rebuild it) Features: -4 wheel drive -3+R transmission with central differential. The transmission works much better than previously. -steering with Ackermann, working steering wheel and HOG (it's at the windshield now). The steering works fine now, it hardly worked in the prototype -V12 fake engine -independent suspension on all wheels -Everything can be opened. More images here. Video and real photos will be made in the weekend.

At last! That part in different color. I still don't get why some pieces are made in various colors and why similar pieces aren't That part was definitely annoying in only grey.

um.... Do you mean MOCing as an activity, or making a particular MOC? I assume the first. I started right away with creating own stuff. I can only do stuff on my own if I'm interested, and modding is something that is totally not interesting to me. I did buy sets and build them all, usually their B models too, to learn the technique, that was totally new to me. Anyway, just jump it. Don't stall for time by talking about it.

Pics from the bottom please! The chassis seems to be pretty interesting too. Can't wait for the cad file.

Can't wait to see the pics. This is awesome

I had more problems with the length of the axles in the steering systems. The current model also has 10 gears. I can't turn the wheels if the vehicle is standing still, but I use 8880 tires and the model is quite big and almost finished. But it turns okay when the model is moving. In the previous version, the steering didn't work at all due to the long axles, and because I geared things down.

Yeah you can steal some techniques from me too. Like hacking, giving up on features, etc I meant that the CV joint in the hub adds pretty big friction to the steering and reduces the angle that the wheels can turn. I managed to add 4WD to my car, and I was shocked how poor steering became.

Nice progress so far! Building a supercar is full of surprises. The biggest for me so far is the very poor steerability of the driven first axle. Did you experience it as well? Can I ask how flexible the chassis is? Does it twist under its own weight (if you lift the two opposite wheels up)?

The model has a large body, you could use more turntables on top of each other to transmit the rotations.

Wow, thanks for quoting me. For the struggling part: it is struggling for me. Struggling struggling satisfaction struggling struggling desperation struggling struggling jettisoning then the thrill. Sometimes I just want to give it up, but then I dream about it, I think about all about it in my workplace. For the building experience thing: I don't think that the actual building for the book itself makes up the experience. Making the building harder by squeezing some steps together and not using color coding won't (at least for me) make the build more interesting. It is the evolving model that's interesting (and in that regard, I like the random-like color fashion of the of the models), what parts are build in what fashion (modular build vs non modular building. In what sequence? Gearbox first or structural parts? Similar or repeated/mirrored sub-assemblies are built after each other or there are more steps between them?). Making instructions is an art by itself. Some great MOCs and official sets have dull building, and some not-so interesting or maybe ugly MOCs and official sets have interesting and fun building. Maybe designing models and designing instructions are two very different talents.

Hmm, that axle end thing is pretty sloppy. I understand it's because the 8L with stop axles, but couldn't they put bushes on them? (Don't tell me to put them there myself if I buy the set.)

Well, 8880 was far from realistic. Nevertheless it was a great model, one of my favourites. (gearbox with no reverse, no opening doors, chain driven fake engine, the rear hood deformed significantly when opened, arguably the 4 wheel steering. even the shape was a bit unrealistic, too small seats, we could go on). Pneumatics works like the real thing (like hydraulics), but behaves very differently (inaccurate, not smooth, too quick). LA:s work differently than the real thing but behave like it. I prefer LA:s, the tubing is a bit annoying to me, and honestly I can't imagine little kids can push the tubes on the pins without help. I have strong hands, but it was quite an effort (at least with the new tubes) to push them on, and sometimes the whole thing just slipped out of my hands. Definitely it's not something I would be hacking around and trying things. As for the educational thing: I don't think that learning that Lego machines don't work exactly like the real thing will cause a trauma. The principles of pneumatics and hydraulics are quite simple anyway. Sure, there should be pneumatic sets too.

It can be a toy, it can be an exact replica* or it can be art. I prefer the art, and that the overall model should be good. Perfectly balanced in terms of function, look, building style and building experience. Stuffing as much stuff as you can, or being as authentic as you can (abuse Lego) won't make a good model for me. *for exact replicas, maybe Lego is not the best tool. Use metal, carbon fiber, etc. Or build real machines. It's just my preference. And I consider myself an AFOL (I'm adult at least and build crap MOCs).

You have two independent levers to operate the gearbox, that means two functions at a time. It's another question why those functions together. Rotor turning NOT with the landing gear is kind of awkward.

I'm turned on by the 42009. I've never hear a crane-truck, this seems pretty good looking to me.
