  1. Hi Colin, you didn´t wrote which version you choose. If you are building version with suspension, than you need differential part number 6573, but if you are trying upgraded one, with 3 XL motors wor driving, than you need the other one - part number 62821. Hope this advice will help.
  2. Grove is my favorite MOC, I start with original 42009, after that I change it to full RC (not Jurgen´s ultimate). Next step was GMK 6400 MK II with suspension and full boom with LEGO actuators. Final version is MK III without suspension and boom with 3D printed Efferman actuator. Boom with LEGO actuators work fine, but raised angle of boom was terrible. Carrier with suspension wasn´t bad, but two XL motors located under driver cab wasn´t best idea to power all twelve wheels. In my opinion to much friction. So next gen has to come. MK III without suspension 3 XL motors, each for two axle - but it need V2 receiver and two servos for steering. Now much better driving and steering. Boom with printed actuator is longer (six panels), but heavier. And even with XL motor for actuator, it is very hard to raise (especially in the begining). But when it´s raised and extended it´s a beast. So my opinion - MK III without suspension and effe´s actuator, but you can made your own actuator from LEGO parts.

    Efferman's Custom Parts

    Hi there. Effe are you trying to move your parts somewhere else?? If exist some another similar company?
  4. This one with 3D printed gears.
  5. It´s not correctly visible on video, but there is two Technic reel at the begining of the boom with locking mechanism. And you can tighten the rope at any lenght of the boom. When fully extended, this rope give me another 5 cm in height, with boom bend to the opposite side.
  6. Hi, I make short video of my GMK crane. https://www.youtube.com/watch?v=cqdl2zl8zk0 Enjoy, hope you like it.
  7. Thanks Alex for BI. As I said, several problems has appeared. Some fixed, some remained. Lateral stability improved with added wedge wheels on both side of superstructure. Because of XL motor behind turntable, I cannot add another one on the back. Another problem has appeared - slipping 8t gear for turning superstructure. I think that´s becouse my custom heavy iron counterweight. But without it boom leans forward. Last issue is with powering effe´s actuator. With only one 20t gear for pivot point is not enough for lifting heavy boom, always slipping (at least my one). I must use two gears against each other - but when it´s going up it cracks sometimes. Little headache.
  8. Hi there once again, finally finished MKIII with dual outriggers, efferman´s actuator and superstructure. It´s really big crane when extended. I´m not 100% satisfied with it, there is much work to do with it. I have to improve lateral stability when boom is extended - some wheels or something, Driving and steering is much better with these improved version, than with suspended one. But with ballast on carrier is drivning and steering on its limit, better without it. http://www.brickshelf.com/gallery/Kladovec/gmk6400/img_20180618_162813_small.jpg http://www.brickshelf.com/gallery/Kladovec/gmk6400/img_20180618_164922_small.jpg More pics on my brickshelf gallery.

  10. With Efferman superstructure and six panel long boom. More at: http://www.brickshelf.com/cgi-bin/gallery.cgi?f=574133
  11. Hi, there. I´ve made something in LDD - dual retracting/extending outriggers for GMK6400? I´ve made it for nonsuspension version. It is compatible with it. But there are several cons: - in retracted position 1 stud wider - overall 1 stud higher - less rigid in extended position - five stud more in lenght - it will be problem with cables, which are routed through it in central section Pros: - six stud wider in extended position - bit closer to original crane Hope you like it.
  12. Hi, could you please share your *.lxf file?
  13. Hi all. I´m also finished this mastefully MOC. For power supply I chose small battery box for rechargable AAA batteries. So I had to find out how to pull out BB. And I made this: Here you can see bottom of superstructure where BB are located. Four red bushpins which hold small frame in position. Here is frame. BB out of superstructure. I´m using it without cover for better space consumption. But this way required some cutting. I had to cut small part from black "Technic Pole Reverser Handle" which are used for frame with switch.
  14. That´s amazing. Great job. Any internal pics?? Please.
