I would love to buy instructions for this, even if it is only a cad model that I can use to reverse engineer it. Please give me a PM if that is possible. Superb model! And perfect for display. Lego are probably not willing to make it as they see it as to complex... I find it perfect for technic fans! _ED_

I got the 42139 All Terrain Vehicle for € 50 brand new. 30% off on a webstore in Norway - Jollyroom.no Very happy with that, so I bought two! :)

I got a brand new Sian in unopened box for € 230. That is about € 100 below normal resale in Norway... Birthday gift for myself :) _ED_

Nice to have you active again. Great work thus far! Quite excited to see the end result, no matter if you finish it in time or not. This is shaping up to be a great model! _ED_

Very good model, and would be excelent for a open or model team contest, but I'm afraid I have to agree that this hardly can be said to be technic style... Apart from functions and a little brick stacking it seems to be very little technic. Might help if you replace most of the plate stacking with technic panels or something similar. But you should have praise for making one of the best looking Lego rollers I've ever seen! _ED_

Combining ideas here... How about this for a Ladder? By connection it to beams on both sides you should have a secure connection... _ED_

This looks like the perfect middle ground! Maybe add a 3 L beam or similar behind it to make it look more connected to the base? The curent connection is probably very good, but in the last picture above it seems disconnected from the base.

There is also many mini excavators have adjustable track width to make it easier to transport them. Nice start. Interesting to see what direction you take this in. _ED_

The leftmost cabin fits the ladder very well, and I think it is the best looking. But, it might be a bit big for the scale... Love this model! Great work!

I would try swaping the steps in the ladder for black pins, and fill every hole. That way it seems to have more steps. Might also consider lowering it by using 6 L half beams. As is it seems very high off the ground compared to the cabin. Very cool model! I really love how you managed to take one of the biggest Technic sets ever and make it almost microscale, while maintaining most of the functionality! _ED_

We need some more pictures of the finished model. Looks great so far, but would like a bottom view as well as a better view of the gearing of the functions. Good work so far! _ED_

I'm amazed at how solid you made it look! The parts seems to be a perfect fit, and managing to make it look like that is no small feat... A very refreshing MOC! Keep up the good work _ED_

I don't think the boom is to big compared to the real thing, but making it very square has made it look very dominating. If you could use the rounded panels it would look a lot less massive. https://www.bricklink.com/v2/catalog/catalogitem.page?P=11954#T=S&C=3&O={"color":3,"iconly":0} Also the area between the cabin and the crane base looks kinda skinny... Might do it some good to beef up / cover up this area. But I love the functionality! Really good work! _ED_

What tires are these? Seems I have a hole in my colection... Looking good thus far. Very interested to see how you will implement the pump and levers for the pneumatics. _ED_

Is this the right size to use the older rubber belts for tracks? I think that would look much better! _ED_

Looks like someone took a cute little crane truck and did a offroad makeover on it. I like it! That tiny cabin with widened fenders, new front bumper and larger wheels is almost comical, and it is perfect! Gives the model a real original look! And the improvements to the crane are very good, but is it possible to make a longer, or 3 stage boom? May I suggest something like this? This is a very old crane for a unimog, using old pneumatics and a chain for extending the 3rd segment. It should be possible to build much more compact using string rather than chain, and dropping the pneumatics. _ED_

Haven't had time for any more physical building, but here are the bucket variants I'm considdering. Non of them are "perfect" copies of the real bucket, but both have a "hidden function" of being able to open. The overall shape is close to the real buckets, but I'm still undecided on which is best. Any inputs? I would also like suggestions for improvements if you have any... _ED_

That solves all problems regarding size!

Have been thinking of it, but I feel that is cheating as well.. @Jim How do you rule? Is a tilted bucket ok? _ED_

A little more progress... The Rear part will be covered by a black plate, and the lower yellow liftarms will be swapped for black ones for a complete black rear end. I'm within planned dimensions, but it's gonna be tight. At the moment I've set the limit at 18 wide, 27 long with bucket and 20 high = 9720 cubic studs. If I can make it a little narrower I'll go for 17x28x21 = 9996 cubic studs. Unfortunately I won't have much time to build the next couple of weeks, so I just hope I can finish it enough to see If I need to order any parts before times up. Hopefully I can get the bucket ready for testing tomorrow. The body is currently 20,5 studs, so in the last 6,5 or 7,5 studs I have to make the bucket fit. It will be a tight fit... _ED_

I know. It was meant as a feauture, as I'm basing the build on the Cat 226b As you can see it has a short wheelbase with a large overhang, and I thought this would make it possible to do some wheelies if you really jam the throttle. It also has a very low ground clearance in the back, making it ideal for a model with the drive motors very low. As is it is way to rear heavy. But going with a custom bucket should help some as it will be quite heavy compared to a standard single piece bucket. I'm even thinking of including opening the bucket as a manual function.

It tips back as is, and I still have to add the seat, the control systems, the gear train for the bucket function, and the mounts for the boom. The weight of this will be far more than the boom and bucket, so it will be VERY back heavy, That in combination with 2x L motor for drive equals instant wheelies... Cool, but not exactly what I was looking for. Might be able to weight down the boom a bit, but I'm open for other suggestions... _ED_

This is amazing for a MOC, for a B-model I would love to see a video demonstration of the functions, as well as more details of the swashplate and the control mechanism. Great work! _ED_

Another update. Now the base is almost done, and I have managed to find place for a total of 5 motors (2 Large ones for drive, 3 small for steering/lift/bucket), a complete adder/subtractor, the BuWizz, a PF switch, and still have kept everything low enough to have room for a full cabin. If I could find a way to control a sixth motor I could even include a opening bucket like some of these have. As you can see of the last picture the trackwidth gets quite wide with these tires. I'm at 18 studs now, and could reduce it to 17 using a trick by putting the inner side of the tire inside of the rim. But I don't know if this is legal according to the competition rules... I could also use other tires for 16 studs, and will probably include pics of the finished model with several different setups, but I feel these fit the model very well. I've also made a custom openable bucket that could be controlled if I find a way to control a sixth motor (5th function), but I lack parts to realize it at the moment, so I have to tear something apart before I can build it. Pics upcoming. Now all I have to do is finish the boom, the connection for the bucket, and the superstructure as well as the cabin. I do have one problem though... It is so rear heavy that it wants to tilt backwards. It was meant as a feature, but not to this degree... Any suggestions to fix it are welcome. _ED_

I have the instructions for the first one, and could scan those. The operation is the same for both controll senters, but the 2.0 version came with 3 motors and the first only 2. There are still 3 outputs and the programing is the same. Give me a PM if you want a scan. _ED_
