That Crawler is Really Nice...

On SeTechnic, Nico71 discusses his Lego Technic Orange Trial Crawler at length (in the original French and in this English translation). He provided these and many more pictures:

In fact I don't use the portal hub of the unimog because the distance between the wheel and the center of steering point is really to big for trial truck. Trial trucks have not differential, so I put ackermann steering to increase the steering hability but in order to increase more, the steering point should be as near as possible of the wheel. Also, it reduces conseqently the needed space to steer.

That makes sense thanks for the answer :D

Nico,

first of all, I'd like to say the Crawler really Rocks!

You're a really good builder, I've so much to learn...

Are you planning to release instructions to build the Orange Crawler?

And the video :

:)

Amazing

So awesome! I love it.

Beautiful sights, Nico! Alpine crawler?

Moc looks like it is an original lego set, really cool. Cool climbing ability. And also cool frame body

Watching video, it seems like springs are too hard for this light body. Don't you think?

Great crawler Nico, love the chassis and the space frame looking bodywork, it looks nice and light and performs well, like the winch as well! what's it weigh in at?

Btw someone mistook my landrover crawler for your jeep the other day on youtube!

Some News !

First of all, I have written the review on my blog, not really new but in english with the pictures. The building instructions are on the way.

http://www.nico71.fr/trial-crawler/

Secondly, Ansgar Mährlein, a AFOL follower of the nico71's facebook page has given me a special gift : the buildint instructions for my LPE 3 in line ! That was on my to do list for a while and I am glad that it has be done by Ansgar !

http://www.nico71.fr/lpe-3i-pro-building-instructions/

Ansgar has modelized the moc and created the building instructions with lpub4.0. It was a bit complicated to create the hose so I prefered make a layout helper with color. The moc has been indexed on rebrickable, still waiting for the approval.

:)

The building instructions are available !

You can download the HD PDF or browsing my blog : http://www.nico71.fr/trial-crawler/

The rebrickable link will be available soon !

Thanks Nico for a good instructions, I will do it, sure it has something new to show and I want to learn more and more.

The rebrickable link is available : http://rebrickable.com/sets/nico71/trial-crawler

Good Building !

Nico71 is a FAST Lego Technic builder! Here is his

that shows him QUICKLY assembling his Lego Trial Crawler (in a time-lapse sequence):

I just finished building this yesterday. I'm only waiting for the motor(s) to arrive in the mail.

Renders look amazing as always Blakbird.

Oh ! Looks great Eric !

@Camaro : when you have build the moc, let me know with a picture :)

I have forgotten :

Thanks to Ansgar Mährlein, the building instructions for the pneumatic engine LPE3i are available :

http://www.nico71.fr/lpe-3i-pro-building-instructions/

Also indexed on rebrickable : http://rebrickable.com/sets/nico71/pneumatic-engine-3-in-line

and thanks to a user of setechnic, the bill of material of the unimog V4 are available :

Concering my future plan, I am working on a Mechanical Computer Multiplier with slider system, old motorbike and a prototyp of a special crawler which looks like a "wheeled snake".

Oooh, I always love seeing digital circuit simulators :) Damn, I'm a nerd.

@ Nico... Here's a picture for you.

I had to use red panels and the soft shocks. I don't own a Unimog. (yet)

The soft shocks work ok, but I'll switch them to the 'Mog shocks when they get here. I had to modify the back a little due to parts I didn't have.

Very nice MOC my friend. I've built your Jeep and Roadster also. Thanks for all the hard work, again.

On MOCpages, Berhard Mollema posted 13 pictures of a motorized version of Nico71's Trial Crawler. He wrote, "Nico71's new crawler is excellent and I saw a change to turn the back axis into a steering axis. Also check http://www.nico71.fr/ So 1 xL motor for driving and 2 motors for steering."

So both the front AND rear axle steer?

Yes he specifically wrote both axles steer and you can tell by the picture.

Hi all,

You guys are quick in finding this .......I hope you like the modification (extra steering) to this great design....

I also do not have the unimog so I needed to change the body with parts I do have....
