Mini Rally car

[Tamas Juhasz]

In the winter I wanted to make a very small rally car(of course with wires):

http://www.brickshelf.com/cgi-bin/gallery.cgi?f=489098

The main conception was: no wider than 10 studs, 13x24 tyres, independent suspension:

So there is a full independent suspension in this car, like in the real ones. It needs no differential, but I wanted to build in, so the drivtrain contains an original Lego rubber bands on each side:

The suspension also works with small rubber bands. For the steering, one micromotor is responsible, a small linkage transfers the force:

For this, the 6L link was very useful, it keeps also the track:

For driving it uses one M motor, that's the maximum in this size.

The body is studfull, because you can make a better look body with these parts. I put stickers to be more realistic.

On the front, the two small lamps light:

I could drive it in snowy-concrete terrain, this video shows, how it's performed:

Main attributes:

weight: 332g

top speed: 1,37 km/h

number of pieces: 484 db

length: 200 mm

width: 82 mm

height: 82 mm

What a nice Technic MOC! It's great that you could fit 484 pieces in such a small vehicle. You can drive it outside in bright sunlight without having to worry about the sun's infrared light interference with a Power Functions Receiver. The custom stickers are a nice touch.

A big thumb up for this car! I like it so much!

You should put on cuusoo :)

[Zerobricks]

Some clever ideas right there. My personal best is the rubber band drive, its just such a great way to power the small suspension.

[kieran]

Yep nice one, really looks good, so small.

[TimH]

Very nice work! I like how you used rubber bands with the suspension.

[timslegos]

That is one of the smallest cars I have ever seen! Nice work.

Impressive work. I especially like the dual links for the steering, as you couldn't have fitted a rack in there. Do the rubber band drive system skip a lot when driving?

[Edwin Korstanje]

Wow, very good technics in that smal moc you put in. is that micro motor strong enough to stear!?

[SheepEater]

It's cute!

[Crazydance]

Studless body, and I would DEFINATELY buy this off CUUSOO.. On the other hand if someone's willing to make instructions for this one? I have all the parts except three or so, not minding ordering those through the known channels :p

Really nice car

the suspension is very clever

Thanks all.

Do the rubber band drive system skip a lot when driving?

No' date=' only a very little, because the differential makes the equalization. For this it's useful. But there is a slip, when both rear wheels are stucked, so the rubber bands are a kind of resistance for the motor.

is that micro motor strong enough to stear!?

Yes, as seen in the video there wasn't problems with steering. It's so small that the power of the micromotor is enough, and there is a 1,5:1 strengthening transmission with the 24-16 gears. Anyway, the micromotor is pretty strong compared for it's size.

Cuusoo: this moc has wires, and if it would collect the 10000 votes, TLC couldn't publicize because of the "old" parts, like wires. But if anybody wants to build it, I will upload the instructions, I made it also during the disassembly.

Studless body: what's the problem with studfull? In this size, studless would look worse I think. You can do more details with studded parts - plates, tiles. But it's possible to build a studless body for it.

But TLC use the ideas on cuusoo for build a model, they don't do 100% equals :)

This idea is great, IMHO and maybe they build a non motorized version.

I've seen it previusly in your BS-folder, it is really awsome!

Nice compression of many technics in so tight volume!
