[WIP] Sidecar Racers

[Jurss]

I want to build motocross sidecar, because we had two latvian guys, who were 5 time world champions - Kristers Serģis and Artis Rasmanis. http://en.wikipedia.org/wiki/Kristers_Ser%C4%A3is

As i don't have cross tyres yet, so i decided to create somthing like this

Interesting project, I will follow topic and waiting for updates:-)

You planning RC or static model?

[Jurss]

I don't decided yet. Biggest challenge is placement of 8881 battery pack. Maybe other will be easyer to integrate.

Of course, there ir pretty much space in sidecar. Placement could be so

[Jurss]

Culdn't find anymore 42007 set in local stores, ordered first time something from bricklink - i need chain and cross tyres for cross sidecar. This will be later, after racer.

But I see large wheels Not motorcycle one...

I LOVE THIS!

I'm a great sidecar fan and have designed a number of different chassis on LDD. If you could get this to work I'd be extremely impressed!

[darsedz]

Can you publish or share some designs?

[Jurss]

That will be other type - cross sidecar

[Epic Technic]

This maybe extremely hard to do but make the receiver the driver. Actually I saw this one or a similar side car in the BMW museum.

That would be easier, since that one doesn't have to steer.

Possible arrangment

First steps

I'm afraid, that i will disassamble this, and recreate more like spaceframe. Something closer to this

[Lakop]

Interesting one. Look forward to this one.

Dont't have time to build something, just collecting information

[Jurss]

Some progress (rebuild from scratch) yesterday

Possible size

I thought, that it will be pretty big, but not so big ...

I don't have so much panels. My this years lego budget is already empty and wife angry ...

If i'll use smaller wheels (which i also don't have for something like this), then it will be almost impossible to create front suspension. Now it is almost as real.

I have smaller wheels only from 42037 (it wont be very incorrect, as it will be somthnig like dune sidecar then, and overall dimeter is close to those already used) and 42035.

[Jurss]

Just bought 42026 and 42027 for smaller wheels. I'm sick ...

So it seems that there will be first some smaller version.

I like this so far. This is very unique, for a Technic model. Not very MOCs are sidecar racers.

Here is a design I made a while back, but feel free to use any of the ideas on it.

It has some fundamental flaws, such as the sidecar wheel being too far back. Plus I have never tested it at all, therefore it could all work terribly. Some inspiration hopefully though.

P.S. Sorry for the slight hi-jack

It's OK.

This design looks good, but i'm afreid, that it wont hold the load, it will breake in the midlle or somewhere else. Those parts will slip off each other.

And look what i have done with smaller version

Steering right ...

... and left

to be continued and ended ...

[cgg199]

Yeah I kn ow that design won't work, especially with the brakes an gearbox. I just thought it might be quite useful.

I like the progress, and that hub-centred steering is really nice on such as small model.

[Jurss]

Rebuilded rear part and added sidecar. Experimenting on body

[Jurss]

It think, i've finished with small sidecar

I desided not to build exact body, because i came to conclusion (maybe wrong), that on this size of wheels it is almost impossible to make goog looging body. To make good looking body, bigger wheels are needed, something of this size

but again, those are not wide enough.

[Jurss]

Motocross sidecar

Started from front fork

Made pretty close to original, but, because of two hard shock absorbers, they practically don't work, forn fork just bends

Some start of frame and rear fork, which I shortened later.

Main frame almost copleted

Cooling and exhaust

Closer look at engine with carburator (or SLT) and filter

And then I forgot to take some pictures form procees, thats why theres first (maybe also last) days result

It would be nice to have some smaller, narrow wheel for sidecar, but i don't have one, and maybe theres also nothig like that form Lego.

[darsedz]

very nice...

[weavil]

Great work! Wish I had a crap load of chain links like most of you.

[Jurss]

I didn't had, but i bought (and it was crazy) 2x 42007 for this project ...

I don't have pics, but i added fornt mudguard, and my son added racer - some of guys from Hero Factory, they fit very well
