  1. 3rd in the series of my Ultimate models, here's the fully remote controlled version of the Lego(r) Technic 42082 (released in the summer of 2018). Just as with the Ultimate 8043and the Ultimate 42009, the goal was to make all of the essential functions remote controlled using only Power-functions parts and make building instructions for it. All the motorized functions can operate simultaneously. The remote controlled functions are: Driving with running fake-engine Steering 3 steering modes: all-wheel, front wheel and crab-steering modes Outriggers Rotation of upperstructure Lifting/lowering the arm Extending/retracting the arm Lifting/lowering the hook Manual-functions that were kept from the original model: Opening the grey tool-doors on the side Opening the cabin-door Fitting the outrigger-pads in the vehicle The 4-wheel-drive was kept intact, but unfortunately, the space in the 2 compartments where the chests with the chains and tools were stored, was used to place a batterybox and PF-receivers, so the chests don't fit anymore. Compete building instructions are available on my website

    [MOC] Backhoe Loader V3

    I'd like to answer your question, but I don't understand what you mean. Both buckets are fully functional. The model is just as big as V2, so Power-puller wheels should fit, but I haven't tried yet I built my own analog modular synthesizer, which was quite time-consuming No, you could build the V3 in yellow and use your pieces, or build the V2. It's still available.

    [MOC] Backhoe Loader V3

    After almost 2 years of non-Lego-building, it was time to finish a new MOC. May I present: Backhoe Loader V3, an improved version of my most popular MOC, the Backhoe V2 from 2012. Just as the V2, the V3 is fully remote controlled. Now back in 2012, only the M-motor and the XL-motor were available. Now that we have the L-motor and the servo-motor, they can be used to upgrade the model. Also, we now have the perfect tyres for a tractor, thanks to 42054, 42070 and 42081. The Backhoe V2 used the very rare and expensive Power-puller tyres, so now it's much easier and cheaper to get the correct tyres. The blue colour was chosen to distinguish between my previour backhoe loaders (which were all yellow). Of course, it possible to build this model in yellow instead. A lot of effort went in preventing the use of rare parts. 2 rare parts I was unable to extract were the 2 technic panels on the sides of the front. Remote Controlled Functions: 1. Driving (2x L-Motor) 2. Return-to-centre steering (Servo-motor) 3. Gearbox to select between Loader or backhoe operation (M-motor) 4. Loader (L-motor) 5. Loader-bucket (L-Motor) 6. Backhoe boom (L-motor) 7, Backhoe stick (M-motor) 8. Backhoe bucket (M-motor) 9. Backhoe rotation over 180 degrees (L-motor) 10. Outriggers (M-motor) Non-motorized functions: 1. Ready for PF-lights 2. pendular front-axle 3. Hood open/closed The model can be powered from the rechargeable Power Functions battery (8878), or the AAA-battery box (88000) and 2 SBricks allowing the model to be controlled with a smartphone or tablet (iOS & Android). Improvements over the Backhoe V2: 1. Loader up/down works faster, thanks to the L-Motor 2. Front bucket works faster thanks to the L-motor 3. Backhoe up/down works faster, again thanks to the L-motor 4. Motor for the backhoe bucket is now in the boom instead of the stick, improving the balance of the backhoe 5. Rear wheels are more realistic and much easier to find 6. Nice blue colour for a change 7. Uses the big bucket of the 42030, which iscales better to the whole model As with most of my MOC's, full building instructions are available. You can find them here

    Reasons for using rechargeable battery in the chassis had to do with the available space. Of course, the AAA-box can be used (which are used in the instructions). Reason for using the normal AA-box on top had to do with cost. It's not needed for counterwheight, a rechargeable bbox can be used there as well.

    Yes, the combination of 42009 and 42030 gives you a very good start. You'll be able to compare parts lists soon, as this model has been submitted to Rebrickable.

    Yes, Blakbird made the transparent render. I can make instructions, but I cannot make renders like that

    Manitou Telehandler

    With a parts count of allmost 3500 (!) parts, it's my biggest MOC up until now and together with the Backhoe Loader V2 (with 9 motorized functions using 8 motors) it's the most complex. Using Manitou equipment as inspiration and reference, I finally got to building a fully functional, motorized, remote controlled, rotating telehandler. The chassis and the upperstructure are essentially 2 different models which can easily be separated and joined. Each has it's own PF receivers (or SBrick) and batterybox. Chassis Here's a list of all the functions: * 4-wheel motorized drive (with 1 XL-motor) * 4-wheel steering with return to centre * 3 different steering modes: normal, crab and 4-wheel steering * Outriggers can be extended and lowered The chassis contains a double switch to selects between "drive-mode" and "outrigger-mode". The double switch uses the new driving-rings to switch the functions of 2 motors. In driving mode the motors operate the driving of the model and the switch that selects the steering mode. There are 2 steering modes: normal steering, where only the front wheels turn. Second is 4-wheels steering, where the front and rear-axle turn in oppisite directions. And third is crab-steering, where the axles turn in the same direction. This makes it possible to make sideways-movements with the vehicle in small spaces. It's accomplished by using servo-motors for turning the axles. The front-servo always truns the direction in which you push the controll. The rear-servo is driven by a PF-switch, which in it's turn is moved by an M-motor (with clutch gear). This way, both axles are allways synchronized, you can even change steering mode while the axles are turned. In outrigger-mode, the 2 motors can extend and lower the outriggers (as you'd expect). Unfortunately, the 4 mini-actuators used for lowering the outriggers are not strong enough to lift the enourmous weight of the model. The side panels open up to reveal some of the motors (on the left side) and the batterybox and receivers (on the right side). The batterybox can easily be removed to change batteries. Upperstructure The upperstructure has 4 motorized functions: * Rotation of the complete upperstructure (with 1 L-motor) * Raising the Boom (with 2 Linear actuators and 1 L-motor) * Extending the boom with 3 sections (with 1 L-motor) * Changing the angle of the attachment One of the challenges of this model was making the attachment / hook up and down. The drivetrain for this function had to extend together with the extending arm. In the real machines this is done by neatly folding the hydrolics-hoses. In my moc, it's done by using the red sliding 8-tooth gears introduced in the 42009 Mobile Crane Mk II. The red gears slide along 32L axles togehter with the section of the boom they're attached to. This way, the drivwetrain can be extended to more than twice it's length. Extending the boom is the weakest function of the model. Even when using rollers, there's a lot of friction when the 2 inner sections of the boom are sliding out of the base-section, each with it's own rate. It will not be able to lift a lot of weight. Rotating the entire upperstructure is done with 1 L-motor. The new big turntable from the 42043-set was used and reinforced with 4 support wheels / rollers to ensure smooth 360+ rotation. Since there are no wires running from the chassis to the upperstructure, the rotation is endless. Again the batterybox can easily be removed to change batteries. For cosmetic details, the cabin features an opening door, liftable lever (for better access to the chair) and detailed control panel. Remote controll The model can be controlled either with (4) power functions receivers and customized PF-joystick-controllers or with (2) SBricks. The building-instructions show the version with PF-components. But the PF-receivers can easily be replaces with SBricks, 1 SBrick in the Chassis and 1 in the upperstructions. This is my prefferred means of controll, as the ASBrick-system allows scontroll over the speed of the individual motors. Building intructions Complete building instructions for this model are available here. They come as a PDF-file of almost 600 pages accompanied with all the neccesary parts-lists.

    8043 - The Bucket that Never Was

    Oh man, I really like your bucket, LennyRhys ! Are they still available ? I'd certainly be interrested in buying some from you. They'd look great on my Link Belt excavator.
  10. With the help of Alez Zeimet (AFOL1969) and Strikeman, I've created full building instructions for the SBrick-version of the Ultimate 8043 Motorized excavator. Go to the instructions-page to get them. It wasn't just a matter of exchanging the Power-functions with SBricks. Because of the different shape of the SBricks and the fact that there are 4 PF-connectors on top, the SBricks didn't fit. So I rebuilt the U-8043 and modified it so that 2 SBricks would fit neatly inside the model. And the profile I created for the Link Belt 250 X 3 excavator worked perfectly with this model as well.

    Link Belt 250 X 3 Excavator with instructions

    @ darksheep: The new profile is not available yet, that's why I included the settings for the old and the new profile. It works with fine the old profile, the changes are mainly cosmetical. I don't know why it's taking the SBrick-team so long to make the new profile public. As far as I know, the new profile is finished, just not available yet.

  15. Following up on the Zorex-220 PF-excavator, I found that there were some things that could be improved. Inspired by the colour-scheme of the USA-based Link-Belt Excavators, I started designing a new excavator. Allthough the principles and scale are basically the same as the Zorex, there are many differences: * Link Belt is based on a real existing machine, Zorex is just a typical excavator* Link Belt has fully studless chassis, completely hiding the drivetrain inside the chassis, while maintaining the suspension* Improved driving and slewing thanks to a roller.* Uses L-motor for slewing* Openable cabin-door, cabin-roof, superstructure-side-doors and opening top.* More detailed interior* Greebles mimicing the insides of the machine* Improved scaling by extending boom and tracks Link Belt & SBrick Some weeks before Lego World 2014, I was contacted by the Sbrick-team, asking if I would like to demonstrate the Sbrick at Lego World. They sent me the Sbricks and this excavator was chosen to be the test-model for there prototype-Sbricks. The tests at Lego World turned out succesfull, the model and the Bluetooth-controlled Sbricks performed well. Using an iPod Touch as controller, there was no interference with the many PF-controlled models there. Ans the Sbrick-system allows you to controll the speed of the motors, making the controll very precise and more realistic. So when I started making instructions, 2 versions had to be made: 1 for the PF-version and 1 for the SBrick-version.
