So its a new trial truck i built. It features independent double XL motor drive and live portal axels. This truck is 80% faster than the previous, and can do all kinds of cool tricks with 2 independent motors.












I hope you guys like it :)

For some reason embedding doesnt work...

I can't believe how well this trial truck drives and it seems to go over obstacles without any problem.
The double independent XL drive is also very interesting, but are the universal joints strong enough for a trial truck? In my MOC the cross in the u-joint always pops out when high torque is required.
Great model.

Zblj always makes the coolest Trial Trucks!  My teenage son has been trying to make something like this for months.  We're both looking forward to seeing more pics on Zblj's Brickshelf folder and on BrickTruckTrial.com !

hear hear!

Also, I'm quite new to Truck Trial - or car building for that matter - so maybe a small glossary would be nice: what are live portal axels?

[Zblj]

It means the axles have supension, not just tilting. The portal axle is nicely described here:
http://en.wikipedia....iki/Portal_axle
In short you gain ground clearance with portal axles.

[sverre]

Nice TT !! The maneuverability is awesome.
Thanks for the link to the portal axle explanation.

[Milan]

Very nice, as always!
And I am glad that body looks good, too. Simple, but good. Most trial trucks are just Technic chassis, with not so much attention to appearance.
It would be great to see outdoor video!

[CloneCommanderDelta7]

Great.  The only thing that could be changed for the better (if you could though) is have more traction in the tyres.  If only, but there seems to be limitless possibilities when it comes to Technic so, ?.  Excellant truck, I still wish I could build one.  I am workingon one though.

The portal axle does not have supension, but raises the center line of the axle higher than the centerline of the wheel. They use geared hun asembely to conect the axle to the wheels. The advantage is higher ground clearance and lower gearing for off roading. The disadvantage is more moving parts and higher engine RPM's.  great for 4wheeling, not so much for everyday driving to to the lower gearing.

I've always been curious about truck trials. where do they take place? how does one go about entering a truck? Are there rules?

If you meant Lego trial trucks, here they are, if not, sorry, someone may find this useful.

These are primary rules, which are, as the time goes, somehow modified, mostly by allowing PF.


What is it
Perhaps you know the original trucktrial idea: Making offroad trucks. The Lego version is basically the same, however the rules are based on Lego parts. The whole point is that you have to build a truck that can drive over rough terrain. The terrain may be made out of Lego, papier mache, wood etc... Controlling the truck can be done by using battery packs, pole reversers and a RC unit.

The rules
The truck:
- Must look like a real truck
- Approx. scale: 1:13
- Excluding the wheels the max width is 24 studs. Including wheels the max width is 25 studs
- All wheel driven
- Must be able to steer

The wheels you may use:
- 81,6x34ZR 8880 wheels and tyres
- 81,6x34ZR 8448 wheels and tyres
- 24x43 wheels and tyres
- 68.824S wheels and tyres

What features are required:
- Real cabin with steering wheel, seats and dashboard
- Working piston engine
- The platform or construction on the back of the truck must have a width and a minimal length of 24 studs

Motors you may use:
- Standard 4,5V motor
- Old type 9V motor (sometimes referred to as 'flattie')
- New type 9V motor (sometimes referred to as 'geared')
- You may use a maximum of two motors for propulsion. You are free to use other motors for other functions, for example steering.

What is forbidden:
- Modified parts
- Non-Lego parts (except for rope)
- Lego RC motors

[Zblj]

Yeah, but those are old rules before power functions came.

[Milan]

True, as I wrote in the second line.

[Jetro]

So is there an official updated set of rules out there somewhere?

[Zblj]

Here are new rules:

[Jetro]

Thanks - should have guessed they were there

[5150 Lego]

Thanks for the links for the rules guys. I wish there were some competions around my area. Sounds like fun!

[Zblj]

I made instructions for the truck in LDD.  There are wheels, 2x 4L racks and 2 new suspension arms missing. Replace one of the 24 tooth gears with a white clutch gear.

Download the file and click generate buidling guide.

Also the rear axle should be like this:

Wow, thanks Zblj!  There are many people who admire your Trial Trucks, and it must have taken a long time to navigate through the Lego Digital Designer software to make the .LXF file.  I just used LDD to display the Building Instructions, and it ends up being 213 steps involving 544 pieces.  I generated the HTML Building Guide using LDD's Toolbox, and will print them out for this weekend's project     

[P.S.  For those not familiar with navigating the LDD program, after you "unzip" the file you'll have to do a "File--> Import" inside the LDD program.  Use the dropdown menu to select the "LXFML" files so that the "Image100" file appears.  Name it something like "Zblj's Lynx Trial Truck 10" and then it will open up in LDD (which can be downloaded from http://ldd.lego.com/download/ ) ].

With the recent release of the ~1,400-brick parts pallette in Lego Digital Designer (LDD) 3.1's "Lego Universe Mode" ( http://www.eurobrick...showtopic=40794 ), Zblj reworked his digital model of his Lynx and created it again in a Lego Universe (LU) version.  He also did a virtual model of his Mini 4x4 ("A small 4x4 IR controlled offroader").  See the links from the Eurobricks LDD Index thread http://www.eurobrick...mp;#entry718480 ; they're listed under the heading "Downloadable LDD MOCs (LXF-files)" .

Alternatively, the Lynx's original .LXF and the new LU .LXF file are available on his bricklink folder http://www.brickshel...ry.cgi?f=425482 .
The Mini 4x4 .LXF file is at http://www.brickshel...ry.cgi?f=417982 .  The two models' pictures appear below.

Thanks, Zblj !      

[P.S.  If you're not familiar with how to "Import" the models into LDD, see my post immediately above this one.]

Go directly to Zblj's Brickshelf folder to get his LYNX LDD .lxf file:  http://www.brickshel...ctions/lynx.lxf .  Right-click on the link, then "Save Target As" to your desired folder on your computer.

thanks for the rapid response.... unfortunately i'm using a mac, and my mouse only has "left click"........ hence i'm puzzled...

On a Mac you hold down the CTRL key while clicking to get a "right click". Some newer Mac mouses (mice?) actually have a right button.

[Sam42]

well that worked!
thanks fellas...
