Dafgek81 Posted October 19, 2014 Posted October 19, 2014 I've seen it, but I don't know how to get pictures and links posted, but I've heared more people complaning about this. Can somebody tell me how to do this the right way? Quote
cheeze Posted October 19, 2014 Posted October 19, 2014 Thats a rather funky looking crane, Again its the same story with the good old technic turntable not being the best for such an application Quote
jorgeopesi Posted October 19, 2014 Posted October 19, 2014 All his MOCs are awesome, in my opinion he builds with the perfect balance to have playable MOCs, I like his tracked machines. Quote
jantjeuh Posted October 19, 2014 Author Posted October 19, 2014 (edited) Thats a rather funky looking crane Looks pretty close to the real thing: I like the BAM colours, very vibrant :) Better than boring standard construction yellow. Edited October 19, 2014 by jantjeuh Quote
D3K Posted October 19, 2014 Posted October 19, 2014 Saw this last week, it is pretty impressive! Quote
750ACE Posted October 19, 2014 Posted October 19, 2014 Stupid AT&T. I can't see the pictures or link!!!!!!!!! Quote
Rishab N Posted October 19, 2014 Posted October 19, 2014 This was featured on technicBricks about a month ago. it looks awesome Quote
jantjeuh Posted October 20, 2014 Author Posted October 20, 2014 Ah, I totally must have missed that. Quote
ritztoys Posted October 21, 2014 Posted October 21, 2014 (edited) Stupid AT&T. I can't see the pictures or link!!!!!!!!! Might I suggest you change your Internet provider, I had trouble using those idiots too. They responded to me that "the internet provider hosting Designer-Hans' website has spam security issues". So we as customers can't connect to a Lego Toy website? I have since ( over a year ago ) changed to Verizon, no troubles at all. :thumbup: Edited October 21, 2014 by ritztoys Quote
jantjeuh Posted January 31, 2015 Author Posted January 31, 2015 Instructions will be available very soon Quote
kamsohal Posted January 31, 2015 Posted January 31, 2015 whats better? hans crane or the witch will be released later in the year. Quote
jantjeuh Posted January 31, 2015 Author Posted January 31, 2015 Han's is definitely more complex and authentic (IMO). Quote
LeocornoProductions Posted January 31, 2015 Posted January 31, 2015 I think it looks better than the real thing Quote
jantjeuh Posted January 31, 2015 Author Posted January 31, 2015 Awesome render by Blakbird that shows the innards: Quote
Omikron Posted January 31, 2015 Posted January 31, 2015 (edited) I wonder if it was possible to use less motors Edited January 31, 2015 by Omikron Quote
Omikron Posted January 31, 2015 Posted January 31, 2015 What would you propose? Less motors obviously Quote
jantjeuh Posted January 31, 2015 Author Posted January 31, 2015 Well, obviously, but which could be ditched? Quote
Omikron Posted January 31, 2015 Posted January 31, 2015 (edited) 9 motors will drain 2 battery boxes VERY fast. So in terms of playability it is not the best decision. If I understand correct from the render some of the double motors are used in a symmetric way to gain double torque/speed on the same function. I would rather prefer using gearing and some asymmetry in the design than an extra motor. Edited January 31, 2015 by Omikron Quote
Alasdair Ryan Posted January 31, 2015 Posted January 31, 2015 (edited) I don't think you could remove any motors,the main body looks crammed. Edited January 31, 2015 by Alasdair Ryan Quote
Omikron Posted January 31, 2015 Posted January 31, 2015 Seems like Blackbird placed main turntable upside down Quote
Paul Boratko Posted January 31, 2015 Posted January 31, 2015 Very very amazing build... :thumbup: Quote
designer-han Posted January 31, 2015 Posted January 31, 2015 I can confirm that. A) the turntable is positioned right in the render. DBG sides needs to be on top. B) batteries do not drawn the rechargeable box very fast. On birthday parties the crane was in operation by kids many hrs without recharging. And, the recharging the rechargable box is done fast, much much faster then the AA batteries rechargeable. Ditching motors... Don't think so. Asymmetrical motor setup for the drivetrain will result in a 'twisted axle' (the one with the worm gears) for slewing. And, the motors for the freefall system do not run frequently. Althought. One could argue to skip the freefall system, then the motor count is 7. Quote
Omikron Posted February 1, 2015 Posted February 1, 2015 (edited) Oh, I see how it works now. The whole "tower" is spinning around the turn table. Was that made to increase stability and to lower the stress on the turn table? Edited February 1, 2015 by Omikron Quote
