Pat-Ard Posted December 11, 2015 Posted December 11, 2015 Hi folks, today I'd like to present you my newest MOC. This time it's not really a Unimog. But the WF trac is based on the MB trac, so I stay in the family ;) The WF trac is the same scale as all my Unimogs and cars, so nearly 1/12.5. The original can be seen here: http://www.werner-trier.com/wf-trac/wf-trac-6-x-6-s/ All in all I used seven motors in this MOC for all the different functions. The main functions are: 2 L-motors for the drive train 1 servo for the steering of the front axle 1 M-motor for the articulated steering 1 M-motor for turning the crane 1 M-motor for the double drum winch - each drum is separately controlled 1 M-motor for the compressor For the crane I used the new pneumatic cylinders. The grabber uses four small cylinders for gripping an turning. The cab can be rotated, but only manually - no room for another motor. ;) I used 3rd party wheels since I wanted to stay in scale... The rear wheels are a little too narrow, but I don't really care :) There are only some small details missing... If the weather allows I'll do a video the next days... Have fun with the photos... So far Pat Quote
Edwin Korstanje Posted December 11, 2015 Posted December 11, 2015 (edited) Great harvester Pat . I hope you don't have many trees in your garden Edited December 11, 2015 by Edwin Korstanje Quote
BusterHaus Posted December 11, 2015 Posted December 11, 2015 Very nice front end and cab on this beast. The third party tires really look good. I'm looking forward to the video. Quote
Pat-Ard Posted December 12, 2015 Author Posted December 12, 2015 Thanks for your feedback Great harvester Pat . I hope you don't have many trees in your garden Thanks Edwin, not anymore Quote
MacKaiwer Posted December 12, 2015 Posted December 12, 2015 Wow, I like almost every kind of working machines and this is a real gem Design is cool and those tires are excellent Nice work, as always, you are the man Quote
2LegoOrNot2Lego... Posted December 12, 2015 Posted December 12, 2015 This is an amazing build!!! Well done... Quote
Siegfried Meyer Posted December 12, 2015 Posted December 12, 2015 As said before absolutely amazing Well executed Pat. Quote
Zerobricks Posted December 12, 2015 Posted December 12, 2015 What a massive beast! Are the 2 L drive motors up to the task? Can we please see the chassis? Quote
Pat-Ard Posted December 12, 2015 Author Posted December 12, 2015 Thank you all for your positive feedback!!! @Zblj: Yes, the two Ls are up to the task... Here some WIP pictures: Have fun... Quote
2LegoOrNot2Lego... Posted December 13, 2015 Posted December 13, 2015 Extremely well engineered!!! :thumbup: A couple of years ago I worked on a Moxy articulated dump truck which uses the same rear bogie suspension... No useable turntables back then, but these 28Z's do the job perfectly!!! Quote
Pat-Ard Posted December 13, 2015 Author Posted December 13, 2015 (edited) Thanks :) Yes, the small turntables help a lot!!! Here a small video: Here a link to the WIP thread in the german forum: http://www.doktor-brick.de/index.php/Thread/4727-WIP-MOC-WF-trac-6x6-S/ Pat Edited December 13, 2015 by Pat-Ard Quote
2LegoOrNot2Lego... Posted December 14, 2015 Posted December 14, 2015 Nice video! Could you specify the steering angle? I mean the angle the front makes compared to the back? It seems not that much... Will there be a video showing more functions of this? For example the cabine rotation? Would be great! Quote
Pat-Ard Posted December 14, 2015 Author Posted December 14, 2015 (edited) Hi Ingmar, thanks... OK, I'll try. Turning circle only front axle steering about 200cm, only articulated steering about 100cm and both combined about 50cm... Cabine rotation is only manual... You would like action videos? Something like this: Edited December 14, 2015 by Pat-Ard Quote
Zerobricks Posted December 14, 2015 Posted December 14, 2015 (edited) I would suggest you replacing the 12 tooth bewel drive gears with 12/20 or knob gears in the chassis. Edited December 14, 2015 by Zblj Quote
Pat-Ard Posted December 14, 2015 Author Posted December 14, 2015 Thanks Zblj, knob wheels need too much space... The pictures of the chassis are old ones. I use 20 tooth gears on each of the four rear wheels... Quote
2LegoOrNot2Lego... Posted December 15, 2015 Posted December 15, 2015 (edited) Hi Ingmar, thanks... OK, I'll try. Turning circle only front axle steering about 200cm, only articulated steering about 100cm and both combined about 50cm... Cabine rotation is only manual... You would like action videos? Something like this: Okay, that seems pretty tight! Watching the video I thought it would be much bigger...so I am wrong and I have to admit you did a great job on the steering as well!!! :thumbup: About the video, yes something like that!!! :thumbup: Edited December 15, 2015 by 2LegoOrNot2Lego...

Pat-Ard Posted December 15, 2015 Author Posted December 15, 2015 Hi Ingmar, glad you like the video :) Your praise meams a lot me! Thanks! Quote
2LegoOrNot2Lego... Posted December 17, 2015 Posted December 17, 2015 Hi Ingmar, glad you like the video :) Your praise meams a lot me! Thanks! You are most welcome!!! "Final" request, could you do a video that shows us a little more of the off-road capacities of this beast? I know it is not a trial truck, but fooling around a little to show us how the suspension works would be great... Quote
Pat-Ard Posted December 17, 2015 Author Posted December 17, 2015 Hi Ingmar, atm the weather outside is too bad for taking a good shot. But I'll take a video when it gets better... Quote
Pat-Ard Posted December 17, 2015 Author Posted December 17, 2015 Hi Ingmar, the weather cleared a little and I took the chance for taking some small shots. Hope you like it... Have fun. Pat Quote
2LegoOrNot2Lego... Posted December 18, 2015 Posted December 18, 2015 Yes, I enjoyed this movie too! It handles obstacles nice and loading on to a trailer works perfect! What I do wonder, what controller do you use? The acceleration seems a little "bumpy", I mean it is on or off, nothing in between. Or am I wrong? Quote
Pat-Ard Posted December 18, 2015 Author Posted December 18, 2015 Thanks, Ingmar. Glad you like the video... Yes, atm I use the standard remote controller, with the train controller it should be better... :) Quote
Edwin Korstanje Posted December 18, 2015 Posted December 18, 2015 Great video of a stunning model Quote
Pat-Ard Posted December 18, 2015 Author Posted December 18, 2015 (edited) Thank you very much, Edwin. Such words from a master builder like you, mean a lot to me!!! Edited December 18, 2015 by Pat-Ard Quote
