Me?!I'm only a beginner builder ^^ I feel very pleased with your comment !

It looks more and more amazing !

What a strange Unimog ! Does a similar unimog with rear directionnal wheels exist in real life?

How many parts have you still broken? I find it's completly stupid to affirm no rock crawler will be produced still we have some pictures or informations to confirm this ! It can be a manual rock crawler, so there will be no risk to break some parts :) Nobody can tell how the future will be made :)

Where do your informations come from? Personnally, I do not enjoy such a model, maybe because it's very basic : propulsion,steering and suspensions. But if they use new parts ( such as new gears), it would be very welcome :) I really hope we will see longer pneumatic cylinders in a near futur !

Indeed, it's not logical to put Xl motors for steering and only M motors for propulsion. But I don't find interesting to put eight M motors to drive it when you can only put one to have the same effect ( and it's more interessting to build this with one motor for propulsion and gear to connect it with the wheels. Same for the steering.

Do not forget that it's only the sets of the first half of 2012, and as all sets release during this time, they are small and probably only one of them ( if they are confirmed) may contain some pfs elements :)

@captainmib : Yes, I think that it's possible but it's not the solution used on real tatra :) Alsadair, I haven't tried use a rubberband and it's still disassembled because I was not satisfied with it !

Because it's a tatra suspension. If you don't know what it is : look at this picture which comes from the official site : As you can see, if you put a differential between the wheels, the suspension system can not work because they oscillate thanks to a central axle;-)

Maybe is it important to read what I write? ;-) I have clearly said that the cylinder can not lift the skip and it's for this reason that I help it. Otherwise, my truck has nothing to deal with the frame of the Unimog8110!

Hello everybody ! Today I finished my last project which is a tatra phoenix with the 8110 wheels.Unfortunately, the truck does not work properly and I'm a little dissapointed with it but, as we say, it's trough mistakes that we learn, isn't it? The truck weights 2kg153,it's heavy and only four axles support all the weight. These axles propuls the truck via two differentials placed perpendicularly to the wheels. The friction is huge on these axles and the Xl motor has a hard time, same with 12T/20T-8T/24T reductions. The steering works well but the turning radious is rediculous, due to the tatra suspension ( difficulties to build a decent steering with such a suspension in lego). There is an ackermann effect. This mechanism is assured by a M motor and 12T/clutch-8T/24T Two hard springs begin to be insufficient to support the cab weight and the front suspensions work not perfectly ( this phenomenon is increased when the cab is lifted but a priori, we do not drive the cab lifted ^^). Rear suspensions work weel because there is less weight in this part of the truck. The compressor is also powered by the Xl motor via a gearbox ( so I can choose either the propulsion or the compressor) and the reductions 16T/20T-12T. The frame is not strong enough and move a lot when the pressure begins to be high. It was my first pneumatic creation and now I know how I had to build a frame when there is a compressor in it ^^. Moreover, the skip can't be lifted with the pneumatic cylinder because too much force is needed ( it weights approximativly 400g) and the compass lift (?) breaks before. Contrariwise the skip can be lifted on the right or left side just with the pneumatic cylinder. It's impossible to put two pneumatic cylinder due to the frame tightness but anyway the compass break before and I can not reinforce due to the tightness of the frame... As you can see, it's far to be perfect but I have learnt a lot of things and I'm very pleased with the building experience I have had :) So, after this long comment, here are some pictures ( others are in my brickshel galery) and the video :

@Alasdair : it's not because you're building a harverest that you're obliged to make a reference to your build each time we speak about harverest ;-) By the way, I also hope to see an original model, never produced by lego in the few past years. I would appreciate to see a walker :) But besides the models produced, what really interests me are the new parts because I'm primarily a builder and not a collector !

And why can't he build a new one ? I find your creations beautiful and very ingenious, Lasse D !

Yes, they can be attached on pin :)

Here is the new 16T clutch gear with the old to compare the two :

No, I don't mean this gear. I mean this : But the new ones haven't guts ( if it's the right word ), I will take pictures tomorrow

I have finally bought a Unimog and this model is just awesome ! It's also my first pneumatic set so i'm in love for it ! Nobody speak over that, but lego have just produced new 16T clutch without guts (?). So, I think that this new parts can show if you own a new or a "old" Unimog. I will take pictures of these new 16T as soon as I take it apart :)

There are four motors, three M and one Xl. The motor you see is used for the steering.If you look carefully, you can see above it the Xl motor used for the propulsion. The two other M motors which control the La are located above the rear axle.

I'm happy to have inspired you to build one :) Thanks all !

After thirty hours of work, I'm proud to feature to you my third wheel loader. This time, it's not inspired from real machines but seems to look like a hyundai : My arm is similar to the one built by M-longer : His brickshelf galery So, here is my model : It owns : -An integrale propulsion, powered by a Xl motor and the reductions 8T/24T-12T/20T-20T/28T. -A articulated steering, controlled by a M motor. There are two racks, one pushes, while the other pulls. The reductions are 16T/20T-linear clutch-worm gear/8T/rack and 12T/12T/12T after the first 8T to change the other 8T rotation. -Two linear actuors which lift the arm, powered by a M motor and 16T/20T-12T/20T(48/100). It's able to lift a battery box ( ~200g) without problems. -A linear actuor for the bucket, controlled by a M motor and 12T/24T (50/100).The speed is very similar between these two functions. The bucket stay in its position when the arm is lifting, thanks to its position two studs before the point of arm rotation. -Rear axle pendular -Openable doors It weights 1kg600 and due to its pendular axle, bundles (?) a little when it moves. The turning radius is better than my last, which is pleasant when playing with it :). And here is the video : So, I have corrected all the problems of my previous wheel loader and i think that i won't build any other intermediar articulated wheel loaders till lego produces new parts ( such as a part which permits to create a planetary reduction). I will rather build small articulated wheel loaders, or crawler loader, or wheel loaders with steered wheels). I'm open to all your comments :)

Great ! Doesn't the lack of differential causes some disturbances on the propulsion?

Marcus, do not compare what can't be compared ;-) You speak about a model which owns approximativly 3500-4000 parts, a lot of power functions and a other car which is only 1500-2000 parts, and has no power functions. The two cars are built in a different approach and so are not comparable. Moreover, Sheepo took three years to create his Porshe, where Paul took only a few months. By the way, to answer at your comment in the topic studless/studfull, it's not because one person has decided to use studless to reach his goal that studless had to be better than studfull ;-). As many have already say, it all depends of your goals.

It's a great creation but I think that it has too much parts :) Smaller creations will be easier to purchase for everybody !

No problem for me, thanks !

Great creation ! How does it weight? I don't notice any problems about the wheels which don't support the weight of the backhoe. By the way, if you're interessted, I have made an amelioration of jjrailton controller which have some illegal builds. Here is mine : Other pictures to create it
