  1. I started working on this model many weeks ago in Lego Digital Designer first. The whole concept started with the quarter circles from BWE, which are able to perfectly accomodate the small rotors. I was heavily inspired by the (movie) Avatar's rendition of helicopters. After a lot of tinkering in LDD, it was time to start building in real life: It was here I discovered I made a big mistake. The control stick located in the cab used to tilt the rotors was reversed! I had to go back to the drawing board and correct the control mechanism. Few days, fixes and improvements later, this is what the final model looks like: I wanted the colors to randomly switch from yellow to make it look more eye-striking. Where possible I used black 2L pins instead of the blue ones. As stated in the topic name, this is a motorized model, powered by the small LiPo battery box which is hidden in the tail, next to a single M motor: The single M motor powers a total of 3 functions: - Drive rotors (always engaged, spinning in one direction only) - Opening cargo doors and rear ramp (powered by a gearbox) - Working winch (powered by a gearbox) You can see the driveline of all the motorized functions here: The red mechanism at closest to the M motor makes sure rotors are spinning in one direction only, irrelevant of which direction M motor spins. This way changing direction of the gearbox does not change in which direction rotors spin. Gearboy in front switches between openining doors+ramp and a winch. The doors and ramp are actuated by a single actuator located right behind the cockpit: The rear of the cargo doors is connected to the ramp via bewel gears, so both open at once: I also bult a small container which can be easily lifted by the motorized winch: The container can easily fit inside the cargo bay area: You can see the finished model's video below:
  2. Hello to all, I am new here and wanted to share my very first creation with you. This is Toyota Land Cruiser FJ70 pick-up. I build it by using bricks from following sets 42000,42030,42042,42043. I took inspiration from RM8 creations but also in the past I was driving this car quite a lot in raw conditions and I have big sentiment related with this Toyota model. Pix and Video are not pro quality as this is my very first approach to build and share LEGO creation so please don't judge me too harshly form this point of view. I hope you will enjoy looking at this model. In the near future I have plan to make simple video how to build it. Under the below links you will find pix and video. https://www.flickr.com/gp/156725712@N06/bP6n4Q Below is video instruction for Lego Technic Toyota Land Cruiser FJ70 - body (part 2). Unfortunately due to file size restriction in my camera, there is missing small part of the video where is shown how to build roof and back side of the body. However this two missing bits are easy to reproduce based on the pix. For those who would like to built this body it can be also good opportunity to put a bit of own invention.
  3. Building Lego Technic creations and posting videos is a common bussiness for every MOC designer. Coming up with small and large inventions and sharing them is a continuing activity that never bores. However, there is one common dream, one ultimate goal that every Lego enthousiast silently dreams about: to design a professional Lego model. Several builders do what is called 'commissioned work'. Building a Lego Technic model and selling whatever it became to a company or private party. In general, Lego Technic custom models are loved by non-Lego enthousiasts because 'it works'. Several years ago, I got the unique chance to do commissioned work because a company CEO's brother accidentially saw my scale model. I first refused to sell my beloved Luctor, but two years later the one metre model was ready I got positive reviews about the looks, but the most comments were: "wow, it really works". Somehow this model must have been leaked inside 'CEO-land', as one year ago I was asked by the Hoeflon company (based in the Netherlands) to build a give-away Lego Technic model, to be used as a business gift. How cool is it to not receive the 32st boring USB drive, but a complete custom Lego Technic model.. The company builds mini cranes that go inside buildings to do heavy lifting. My task was to build a scale model of a machine that is already very compact in real life. As a result, I present a 1:14 scale model of the Hoeflon C6 crane. (please note I'm NOT paid by Hoeflon in any way, the whole story is just about how things happened and to explain the link with reality). The crane is my smallest MOC for a long time. It was really a challenge to fit all the functions inside the cramped body. The functions are: Track widening Boom rising/lowering Boom extension Fly Jib Rotating superstructure Friction winch Self-locking outtriggers Variable angle outtriggers with over 90 degree range These functions happen in a Lego Technic model of a smaller volume than the 9391 Technic crane set. Over the years I had lost some creativity to build small models so this one was a real challenge. I'm happy with the current setup but who knows.. The model is delivered with black or LBG tracks. LBG track links are slightly more expensive and this quickly adds up when 100+ cranes need to be made. To be fair, I find the looks of the 9391 stunning for the low part count. However, as I show in the video, it does not really work as a crane. The above photo shows the comparable sizes of both models. The front view. Please note the relative widht of the tracks: They are each 3L while the vehicle width is 7L. The resulting chassis is one stud in width! To widen the tracks, the crane has a shifting axle system with half bushes as stoppers. The final result is not the strongest system, but the crane at least has the function! The top view shows why this crane is called the 'Spider Crane': the outtriggers can be seen as the legs. The great thing about building such small models is that every part can be seen and every part has its function. There are very few 'unused studs'. This crane has a 3-section boom. In transport shape, this crane is 12 cm high so all of it should be folded. Therefore it looks like a proper mess when folded in. It is a common known fact that Hoeflon cranes will lift their own weight, because one crane should be able to lift another crane into a cellar. Hopes were low for the scale model as it is fully made from plastic Lego pieces. Under these loads, they will simply bend. Using the correct crane position and the winch, I got one crane to lift the other - just. On this small scale, I could not use the same strong structure from the real C6, so it was a nice result that my building resulted in something with the same strenght. The crane in full extended mode. The shape changes dramatically when the boom is unfolded. It reaches a maximum height of 42 cm. This model is meant as a business gift. This box was developed by a third party and it looks great. It is just big enough to contain the 425 parts and the A5-sized building instructions. I spent really hours drawing a 3D model and creating building instructions with lPub. By doing it yourselves, it becomes clear how much time goes into it.. The agreement with Hoeflon was: me delivering the PDF, Hoeflon doing the printing. I'm really pleased with the end result. To conclude, this MOC shows that you don't need a lot of parts to build a fun Technic model. I have many parts now compared to five years ago, but all of it is useless when someone knocks on the door to ask for a small scale model. This model also shows the problem of modern Technic sets from the store shelves. They are built large, very large. The 8265 Wheel loader is an example. It is enormous, while having less functions than this small crane that will fit into its bucket. Now the size may speak to the inner desire of the (hu)man to posess big things, but personally I like finesse and elegance over size. It is my big hope that TLG sees this in time, otherwise the awesomeness of new Lego Technic sets will fade away. The video
  4. My first creation, a European three axle dump truck. It uses 2 XL motors for drive, a servo for steering, L for dump and M for winch. I have decided to use 3 small turntables to create 2 pendular solid axles in the rear. I am happy with the result as this is not meant for heavy offroad use. It does the job nicely. No front drive, but oh well, goals for next model. I am very happy with the looks and color scheme and am hoping to find a good reaction from the community any questions about model I am happy to answer! Thanks for viewing!

    WIP Tow Truck

    Hello Eurobrickers! For a long time, walked behind me the idea to build a tow truck, the more so that more and more the tow truck appears in the BS gallery, so I decided to build it myself. However, my favorite version, americkan style. I long it goes down, but overall I'm happy with the results of their work. Of course, the tow truck will be fully motorized. I told myself that the car will be after 3 lockers for equipment on each side, flashing light beacons of his own design, active fake 8 V engine and, above all, the main functions of the tug, and so drive, steering, outriggers, winch, towing arm with folding and rotating fork and a tower with a sliding and lifting the boom, which is still under construction all the time. For photos I used so far, the boom of a set of 42009, although I admit that even quite well with the tow truck. The outriggers for now can lift a model, but as it's ready, I suppose it will be too heavy to support the tow truck. We will see in the future. Initially, it was the drive on 2 axles, but changed it to 3. The lifting arm of the towing I wanted to use a large Linear Actuator, but it took too much space, so it is on a small Linear Actuator. And so far it looks the effect of my building.

  7. When building trucks (pickups, trial trucks, etc.) that have motorized winches, do you use a dedicated motor for the winch, or use a distribution transmission from the main drive motors? A dedicated motor would be simpler, but then you'd need a separate channel for it and the motor would be dead weight when you weren't using the winch. Using the drive motors would allow re-use of the (presumably powerful) drive motors, and with a differential you could have the motors drive the vehicle forward as they also pulled the winch in - which seems useful when using the winch to self-extract the truck. On the other hand, a distribution transmission would add additional complexity. Specifically, I was thinking of (at some point) building a part-time 4x4 pickup with a winch on the front, which would have the following modes of operation: FWD high 4x4 low winch retraction (with the drive wheels in forward or neutral, for self-extraction; or the wheels locked by a brake, in order to use the winch to pull another vehicle) winch extension (by hand, using a ratchet or something similar to avoid having to back-drive the winch motor) I would probably use 2 XL motors and would lean towards using a distribution transmission for the winch. What do you think?
  8. Hello! After some weeks there is my newest publication, a Land Rover Series I model. I'm planned to make a real off-roader long ago, with this I wanted to build a realistic one with realistic looking chassis. It could be another famous off-roader, but this is the first Land Rover, and it matters me a lot. So the moc: http://www.brickshel...ry.cgi?f=531411 Wheels, motor, gearbox: This wheels are made from the 81,6 mm tyre and from the 56 mm wheel. This is enough narrow yet to make this model with it. The model has the standard four speed gearbox with my definite control (see my other topic for more). This model was built a few month ago, that time I didn't have my improved gearbox with the same function, but this also did it's job, at last it didn't came so much load, there is a gearing after the gearbox. One RC buggy motor is there for propulsion (the noise is it's noise - don't ask me about that, this is the standard noise of this high rpm motor). I used that because of it's high rpm, there is a lot of gearing after that including the low gear/high gear gearbox. In this model, my goal was to make a realistic looking car with a realistic looking chassis and technic, performance was secondary. With the secondary gearbox there is in all 6 speed (two is the same). Sometimes in low gear, but it goes everywhere. Chassis, suspension: The chassis is a single ladder type one, with strenghtening beams an plates. The chassis itself contains every working mechanism: The suspension is made from technic axles, to be like leaf springs, and it works like that. There are positioning links to hold in the right place the axles. A small 6 L link holds transversely the front axle. I made the housing of the differential in the rear axle: http://www.brickshel...y.cgi?i=5898328 The steering, as in the real one isn't made with gear rack, but with a linkage-like machanism. The suspension performed surprisingly good on terrain. Has handbrake, it prevents roll down in forward direction. All function is remote controlled, the on/off switching of the low gear and winch also, by two micromotors. Under the hood I placed a 4L "fake" engine: http://www.brickshel...y.cgi?i=5898334 Body, etc.: Basically the body is a simple plate body with some liftarms and bricks. Of course, the front part was the hardest section. This front look means the Land Rover itself, very easy to recognize. I tried to add many details to the body, like mirros in the left side, turning lights, number plate, door handle to be less monotonous. Inside there is a big cover from a western set, we can find under that cables and technical parts. The steering wheel works, with these old bushes: It has an advantage: the turning is smoother than U-joint drive. Except this it's only an interesting technique, typically for applications which aren't require much torque. Video: (intro is also off roader-like, I didn't find a flat surface) Main specifications: Weight: 1555 g Speed: high gear: 1: 0,50 km/h 2: 0,82 km/h 3: 1,25 km/h 4: 1,67 km/h low gear: 1: 0,19 km/h 2: 0,32 km/h 3: 0,56 km/h 4: 0,92 km/h Length: 387 mm Width: 192 mm Height: 198 mm Scale: 1:9
