bpavsic's Trial Truck 006 Has LDD Building Instructions

[DLuders]

Great credit is due to "bpavsic" for making a MONSTER TRUCK (Trial Truck 006) in Lego Digital Designer and in real life! It's not easy making an LDD file of a Technic MOC; only Zblj (and now bpavsic) seems to be proficient at this. The 4-wheel-drive truck uses 2 ea. Power Functions XL motors and 1 ea. Medium motor, and it has full suspension: http://www.brickshelf.com/cgi-bin/gallery.cgi?f=431866 . After you view the 16 photos on that Brickshelf gallery, be sure to save the LDD .lxf file -- you can build this MOC using LDD's building instructions!

Nice model. And in his Brickshelf-folder you can see what outdoor-trucktrial can do for your parts:

Sand is especially bad for LEGO-gears, but you do get a lot of outdoor-driving fun.

And those tan bevel gears, in axle will broke soon. Knob wheels are better. Ujoints are very weak too.

[Mortymore]

When I see a TT model with traditional U-joints, I immediately discard the model as being actually good for TT.

As for gear, I supose (since I have any), that if there's something that could be better than knob wheels, are the old expert builder gears g9, g15 and g21

I noticed that the model may be running to fast for TT, so he has a lower torque than desired.

But in any case, I wish I had the parts to build it, like dluders did, because it's a good start since there's instructions available, and then one can think how to improve it.

I appreciated the effort of bpavsic and dluders

Cumps

I would not dismiss the MOC just because of a few bent/broken parts. If they break, simply replace them with the extras you have. They only cost (at most) US$1 total. Compared to the cost of the parts needed to make the MOC in the first place, that's "chump change."

I've playing with zblj's trial truck (Lynx) for several hours on our show and none of U joints broke (it has double XL motors and transmision over 4 u joints). I drove it over real rocks and some really hard terrain and I could not imagine worst conditions, so I think that U-joints are not so bad. I agree on those bevel gears though: those get deformated pretty fast when under stress.

Hey, i accidently found this thread :)

Btw, the LDD file is not totally complete, because there are no old big panels in LDD (that are used on the car). Also the picture of the "broken" parts is not from this truck. The 20 bevel gear was melted in another truck that i made (TTB-005) in a 90 degrees axle connection, which wasn't supported enough. The 16 gear is from this truck but not from the last version of it where the gears are sufficiently supported. The Axle is from the rear left wheel (i have no idea why only one of the axles was damaged. But there is some info on the internet, that some of the 5.5 axles are weaker then others (they are distinguishable by color).

About the tan gears and u-joints. I was on an offroad competition and before that, i spend about a month playing with the car outdoors. No u-joints or 12g tan gears were harmed during it all :) The motor to wheel ratio is 3:1, which is right about there for a nice speed / performance ratio. There is not that much torque on the joints & tan gears because the main reduction comes after them in the wheel hubs (thanks for that idea, zblj). We also had rope pulling on asphalt! The cars weren't moving at all, wheels weren't turning because of the grip so the motors were stalled. And nothing broke either.

When I see a TT model with traditional U-joints, I immediately discard the model as being actually good for TT.

Which is completely wrong. There are many trucks with portal axles and traditional u-joints, with 3:1 gear reduction between the wheel and the u-joint, and I've never seen a single u-joint break in these. I believe that before you discard a model because some part is used, you should see how it's used.

Very good truck! Will you make instructions? I realy like the front bumper

[DLuders]

Um, the Lego Digital Designer .lxf File (found in the original post) IS the Building Instruction -- TTB006_Model.lxf .

Yeah...about that.

Am I crazy or is LDD super impossible to use. I mean, great, it has nice graphics for the building instructions but what I really need is a FULL parts list for brickstore and frankly the ability for everything to show up properly. Unless I missed something, when I loaded the file it was missing many of the upper parts and was also built with different panels than what were pictured. When I quickly searched how to convert ldd to mlcad it was even worse. More parts were missing.

Anyone have any experience...I would love to build this model and place it next to Grazi's Big Foot....mainly because this one actually drives!

To make a parts list with LDD you need to use Superduperkalle's LDD Manger.

Ok, Done.

Although I will say that was hardly a perfect process either. I think the problem is more that the ldd file was not complete anyway. Nevertheless, the discrepancies were all cosmetic rather than anything else.

Thank you for that information.
