Blakbird Posted July 10, 2014 Author Posted July 10, 2014 This is also on my to-build list, I already have all the parts. By the way, what was the error in the instructions? I hope to avoid it myself ;-) In the image below, there should be a 12 tooth double bevel gear where you see the arrow. Without it, one of the functions never gets connected to the motor. Very nice review Blakbird, thanks. Is it possible to make a picture from the backhoe next to e recent flagship? I would like to see the size and i dont have the other backhoes Here it is next to the Unimog: Quote
Lakop Posted July 10, 2014 Posted July 10, 2014 Looks a challenging build but worth it. It's a nice scale and must provide endless hours of fun. How powerfull are the buckets? Can you scoop up soil etc? H Quote

Can you scoop up soil etc? There are only M motors for lifting so the power is limited but adequate. I would never put soil in my lego model, but I'm sure it could lift various light weight payload. Ah, Jurgen actually warned me about this error when he sent me the instructions. I guess he forgot to tell you Or he did tell me and I forgot. It was years ago, after all. Quote
IJsmuts Posted July 10, 2014 Posted July 10, 2014 (edited) Here it is next to the Unimog: Thank you very much sir! You're right it's not the same scale, but it's close and I think they look good together! Edited July 10, 2014 by IJsmuts Quote
Duky Posted July 11, 2014 Posted July 11, 2014 Can i use the remote control from the Ulimate 42009? or is the train remote controll necessary? Quote
Blakbird Posted July 11, 2014 Author Posted July 11, 2014 Can i use the remote control from the Ulimate 42009? or is the train remote controll necessary? I started by using the remote from the orange Zorex, but I found that the train remote is really necessary. The backhoe is so fast that you need to be able to start and stop it gradually. Perhaps you could change the gear ratio to make it slower if you wanted to use the normal remote, but the gear path is very direct so there is not much opportunity for change. Quote
kristl Posted July 11, 2014 Posted July 11, 2014 I think the train remote makes it drive much more realistic, because you need to move slow when you are aproaching a dump truck for instance, or backing up. And the play value is great, it's quite capable loading bricks or beans. Quote
Jurgen Krooshoop Posted July 12, 2014 Posted July 12, 2014 (edited) Thanks for the great review, Blakbird. Indeed, raising the rear excavator is the weakest point of the model. When it was designed, there was no sign of an L-motor yet, and an xL would never fit. So the only choice was to use an M-motor with lots of gear reduction. However, when I rebuilt the model for Lego Fan Welt 2012, I replaced the 2 M-motors which go into the gearbox with 2 L-motors, it was pretty easy. The gearing was adapted to the new speed and torque. However, it didn't increase the performance much... Edited July 12, 2014 by Jurgen Krooshoop Quote
Dafgek81 Posted February 13, 2016 Posted February 13, 2016 Hello Jurgen, I bought the instructions foe this wonderful model from you. Can it be build and used with SBricks? And can you make a partial rebuild instruction for the replacement with L-motors you mentioned above? P.s. Sorry for bumping this topic, but started today building the excavator arm with the parts I do have, so that is why I am asking it now. Quote
nychase Posted March 14, 2016 Posted March 14, 2016 Since it was bumped once and no response Ill bump it again. Jurgen, with the xerion tires coming and some other useful parts (motors, s bricks, 13x23 bucket, 6L yellow liftarms) that now exist would you consider making a V3 of this backhoe that everyone loves? I myself haven't collected for it yet which has been very difficult considering Eric got many of the parts for his directly from me. This is one of a few old MOC's that jump out at me as greatly benefiting from an Sbrick too. Also, everyone should keep in mind that without the PP wheels and removing the 4 PF IR controllers (train included) and 4 PF receivers the cost for this model do go down quite a bit. The xerion tires and the larger bucket are bound to be cheap for a while. So yeah, I'd love to build this and I would love even more if some of the problem areas were perfected. Quote
emielroumen Posted March 14, 2016 Posted March 14, 2016 Does the price goes down if you compare the cost of 4 PF receivers and 4 controllers to 2 sbricks? Quote
nychase Posted March 14, 2016 Posted March 14, 2016 Nope, I failed you there. I was thinking that it needed one sbrick but sure enough it needs two! I think the cost is pretty much the same. Sorry! Quote
2LegoOrNot2Lego... Posted March 14, 2016 Posted March 14, 2016 You have to realize you need to add extension wires to the SBrick... On the other hand, the control is so much better and so much more fun. I would definitely choose SBrick... Quote

Backhoe look's rather good with Xerion tires ... I hope we'll get new tread for front wheels also ... Quote

I did the same thing to mine! I agree that matching front tires would be great, but I'm not holding my breath. Quote

Dafgek81 Posted January 30, 2017 Posted January 30, 2017 (edited) I am currently working on this beautiful Model, will put the 42030 rims on the back with the Xerion tires and I think yellow dishes like on the Xerion. Are there dishes around that would fit the front rims nicely? I will go looking in scale model land for front tires, hate the balloon things on these Lego machines. Still hoping for a bright idea from TLG. And sorry if this is seen as bumping, but starting a new topic for something already discussed here seems to me like overkill.
