Well, the older readers of Eurobricks might recall this model, being first released in 2007. At that time, this MOC was innovative, as it had the newly introduced Power Functions on board. And, the model performed quite well outdoor in snow conditions which could not be said for the 1st Leitwolf I designed in 2005 with the 9V system motors. As the Leitwolf remains one of my favorite MOCs – and I designed many MOCs the last 15 years – I had always in mind to remake this MOC once the time has come. And, here it is in 2024, a R3 release of the Prinoth Leitwolf, a major 2007 uplift as LEGO released many new useful parts I could not use then. Especially the mini linear actuators became very handy, controlling the blade and tiller functions; in total 7 of them are used in the Leitwolf. Another useful part to mention is the Technic Connector Block 3x3 ‘Biscuit’ (part 39793) that provides all the necessary mounting points (and holes) on a small footprint to introduce the front blade tilting ability. Same story applies for the Technic H-frame (part 14720). New added LED lights (front and rear) provide even a nice appearance during the evening, the normal working time of snow-groomers in the field…. Indeed, you do not want to ‘ski’ into a groomer during day-light descending…. Functions that just reappeared in the R3 version are the track tension mechanism (shock absorber springs), the working V6 engine and the pneumatic level adjustment. The removable Drum Winch is still there, but equipped with a ‘bigger’ drum and snow covers. In real, these drum contains ~850 meters cable length! I designed 3 (!) different R3 versions, to suits everybody’s needs. The most advanced version is powered by a BuWizz 3.0 brick, that one features 6 functions: 2 powered tracks, front blade raise/lower and tilt, rear tiller raise/lower and switching on/off the LED lights. The BuWizz 2.0 version and the Power Function version just have the original basic 4 features. Only the front blade tilting must be done manually in these cases. And, if LED lights are used, they just are ‘always-on’ when powered. I must admit, the Powered-Up XL motors do have a nice form-factor and can therefore 'packed' easier within the model compared to the round Power Functions XL motors. At the other side, I use frequently the Medium Motors, and the availability of this version in Powered-Up is just awful; it seams LEGO terminated the manufacturing, but nothing official. In general, that's in my view the biggest omission of Powered-Up, the (lack of ) motor continuity / availability. That's why I designed a traditional Power Functions version as well; just to be able to drive the groomer around when I reach 80 years... as PF will survive.... and all the new App-driven Systems most likely not ;-) To control the Leitwolf is quite easy. For the BuWizz 3.0 version, I created a functional lay-out (see above) that provides a smooth performance. It speaks for itself I guess. The Power Functions version is of course straight forward; in this case I use the 'train controller' for track movements, and just the 'bang/bang' on/off control for all blade and tiller functions. Of course, I tried this Winter (February) in Austria the Leitwolf… and as expected, the BuWizz 3.0 delivers significant force; means, the model worked flawless in snow conditions. Real fun, and lots of impressive eyes by skiers on the slope. I hope you like this R3 version; I think I reached the limits again with this model (means, limits that make a model still work as intended), and probably it will take another 10 years before a R4 version will be released 😉 More information of the model, and pictures can be found on my Website: Technic LEGO site of Han (designer-han.com) Note-1: for those visiting LEGOworld NL this Autumn, just drop by to see the Leitwolf R3 in the Fanzone! Note-2: Renders all made in Studio Last but least? And, not the most important note; building instructions are available for all 3x R3 versions. Just if readers start asking ‘do you have BI’s available?’ -
Hello everyone! In this thread I would like to introduce you to my lego technic pistebully. I tried to build as detailed a model as possible, and now, after 6 months, I'm done. The remote-controlled features are: Driving lift/lower snowplate tilt snowplate turning snowplate Alpineflexfräße lower/lift alpineflexfräße activate I hope the pictures are ok : Her is the Link to the Video that i was made:

So it's been a long time since I've done any building that wasn't an out-of-the-box set, and I quite liked the challenge of the C-Model contest from a while back (TC5 was it?), so I figured that was where I'd pick up... When I first saw images of 42038, I figured that it would probably have a snow groomer as its B-model. We got something different instead, which was great, but I decided to have a bash at a snow groomer myself anyway. I tried to get as much functionality as possible, at least similar to what the real thing might have. Features are: The front blade can be raised and lowered with a mini LA, controlled via the 2-point gearbox behind the cab The rear blade can be raised and lowered with a mini LA, controlled via the 2-point gearbox The front blade can be tilted left and right from a control behind the cab An extendable winch, which can rotate 360 degrees via the control at the back On with the gratuitous photos: Front and rear blades raised. The controls. The nearest operates the gearbox, while the middle tilts the front blade. The front blade raise and tilt mechanism. The rear blade in the lowered position. The winch controls. All photos available in full size on my Flickr. Hope you all like it
