Hello fellow builders. I'd like to introduce my new creation. This time I decided to make a light-weight motorcycle - Café racer. So I have recently bought Moto Cross Bike (42007) with the idea of putting it on my shelf, because I really think it‘s a great set, but then I have decided to modify it. I was inspired to do the cafe racer look, since it‘s my favorite style. This one is loosely based on a BMW motorcycle. I wanted to create a boxer engine that BMW bikes are known for. The Engine came out a bit different than what i originally intended because I wanted to give the cylinders a more complex look, but I could not manage to do it, maybe because of the lack of pieces. This cafe racer may not be as detailed as my previous models. There aren‘t many details on the engine this time, the gearbox takes a good part of the engine space but in the end it turned out pretty well, having a clean and simple outlook of the classic motorcycle era. Inspiration: BMW R75/5 DS Features including front and rear suspension, Two speed gearbox (with neutral first and second), cardan shaft, working steering, a V-2 aircooled BMW boxer engine with moving pistons, and a kickstand as well as other smaller details: a big fuel tank, exhaust,a seat, headlight. The handle bars have a quite interesting looking grips, I also added a side mounted license plate. Thanks for taking your time, please tell me what do you think about it . -

Hi everyone, I am pleased today to present you the latest changes to my Caterpillar Ct660: the most important being is that I managed to pass the frame with single propulsion from Ingmar (2legoornot2lego) to a 6x6 chassis! It took me a while to get there, but I ended up doing it by completely redesigning the rear axles. The second change is the addition of a dump bed, which was not at all clear but has been greatly facilitated by the new configuration of the rear axles. For my truck I was inspired by Ingmar's trucks and thanks to him because this is the first time I am able to keep one of my moc as long (for 9 months). Normally they stay nearly 3 to 4 months assembled! Functions Steering done by a servo-motor connected with two universal joints to the front axle; Propulsion: motor-XL> 12t / 20t-> 12t / 20t / differential; LA (tipper): m-motor-> 8t / 24t-> LA The bucket is operated by a switch hidden in a control panel: For the aesthetics of the dump I opted for something simple, that is to say, square edges. And visually, it goes well with the design of the truck. Here are more photos: Fo now I'm petty satisfied with the result of my truck Feel free to ask questions and give feedback. On this good day to all! -

I'm very proud to show my latest MOC. The Deadly Nightshade Offroad Buggy! I've had my RC parts for over a year now and never done anything with them, so decided that it was time to build something. My goals were to create a MOC under 1kg and with super flexible suspension, with some good looks, being very low and sleek. I love the front suspension! It turned out great, very light and quite strong. The rear isn't soo good, so I might update this a bit over the week. Total weight is 960grams. Front suspension travel is 5 studs. 3 sets of LED lights are used for night driving! Plans are now available from MOCplans http://mocplans.com/designer/deadly-nightshade.html Video will be about a week, I want to find some good terrain to test it out on. Any comments or questions are welcome! Thanks for looking. -
Hello, I'm looking for a good Lego tailgate for a truck I designed. Does someone have a good idea?

Finally I get some time to build! WOOT! Well I've been wondering what to make for my next project, as I really wanted to make a modern curvy supercar for once! And just when I was about to give up look what pops up! What can I say? I love the looks, and I wasn't really a fan of the old and really old GT, but this one I like! I'm also looking forward to building in a new style for me consisting of Black and Blue rigid and pneumatic hoses. The idea is for it to be ultra light and cheap to build using 8070 rims and tires and possible those nice Ferrari rims. I'm not sold on the back of the car tho, kinda looks like a skull with firey eyes! LOL Looks nice in silver! http://www.motorauth...icago-auto-show Here is my WIP The bodywork will be completely pneumatic hose, and I'm aiming for under 1kg final weight. The hose on the Left is 3rd party, slightly more stiff and off blue tho. I must express my disapointment that my previous thread was locked after only 4 days with no WIP, but anyway we shall move on. And no discussing what makes a supercar or not! Make another thread please.

Hi, guys! This is Alex - Yakov's son. My father was unwell a little. The heart infarction was alarmed at work, as a result. He asked me to lay out this model. I will tell in confidence, this crane very much is pleasant to me. Well, here you look... -Motor. 4-cylinder, in-line, mounted longitudinally. Due to the complex design of the windscreen and bonnet of rise small, it was decided to make transparent cylinders. Now when the vehicle can observe the work of the engine. - Steering. - Rear axle with differential. Torque is transmitted to the motor through a complex system of gears, due to the fact that the axis of the differential gear and the rack are aligned. -Side Support connected in pairs on each side and down-climb worm mechanism is used to drive the "curve starter." - Differential switch. It is possible to scroll the motor with the help "a curve starter". - The opening doors. - Lifting mechanism of an arrow. A little noisy mechanism, but it allows to fix an arrow in any situation. - The cargo winch is supplied with the same mechanism. - Maximum height. -I forgot to tell. The father with this model won first place at competition "LEGO Technic Russia". Competition was organized and carried out by Egor (rm8). yours sincerely, Alex. -
Well guys, I've been lurking here for a few months and finally decided to join the party. After being inspired by many creations here and elsewhere, I decided to attempt to recreate one of my favorite vehicles from the Mass Effect video game series, the M35 Mako. I've spent about two months building and refining this based on the part inventory I currently have. It has been quite a joy driving around for several weeks over the holidays. Alas, in order to build new things I must decontruct this. My best option was to attempt to learn LDD and "save" the model for next time. This was my first time using the program and mostly it worked out, with only a few alignment issues. I am including an LDD file for now. Please let me know what you think. I hope to do more builds in the future and share them now that I know how :) M35 Mako - Lxf file Here are a few specs: Rear wheels driven by 4 M motors Front wheels driven by 1 L motor Steering via Servo Motor Manually operated turret with full 360 rotation and vertical lift via LA 2 Battery packs + 2 IR receivers fully independent suspension including dual shock system in front A few notes on LDD file: Battery packs and IRs will sit lower in physical model Steering linkage should be raised by 2 studs to fit perfectly (LDD would not allow me to place correctly) Small hard yellow shocks should be fitted between the two black pins on the front suspension, location is just between the two pairs of 5L half width beams. Tilted bottom front panels should connect to pins just above. Front studded beams can be moved one stud closer to body (replace 3L connection with 2L supplied below) LDD would not permit the proper parts Inner arm of each large shock should be connected to the axle located one beam higher than represented. (should be obvious) Please leave feedback! Enjoy!

Hey everyone. I built a compact subtractor as I thought I would give it a go. Unfortunately I doesn't work very well, doing 1-3 turns before the current protection kicks in and stops. Any ideas why? Is it cos I used the L motor and not another XL? I wanted it to turn on the spot so I thought a faster motor would work, and it does, it just cuts out. This is taken with the BB and IR not in place. Cheers.

Hey Everyone! I had an idea to create a guide showing various shock absorbers being decompressed to help anyone trying to guess what springs to use on their Mocs if they know roughly what weight it will be. I tired to press down on each spring at around 90% without bottoming out, to give an idea of the maximum weight each one can take. All springs used are in very good condition, with the exception of the Pneumatic one which grinned a bit, but being almost 20 years old we'll let it off! Anyways I hope this is useful, let me know if you have any suggestions or can give info on the last spring which I don't have. Cheers.

Recently I had the opportunity to buy this nice oldie. It is the 1989 Technic flagship set, 25 years old, but still in great condition Many Technic fans will still remember this set from their childhood. I've never had it, it was too expensive :) So for me it's the first time building it. The box front and rear: Compared with the currently used boxes for the big sets, this is rather a small box. Despite it's age, it is still in very good state. The parts: This set comes with a total of 671 parts. Not a huge amount of pieces, but it does have a good variety. A lot of beams, plates, gears, axles and of course pneumatics. Also some special parts: I've never seen that big black brick before. It's really heavy and is used as a counterweight in front of this machine. Another not so common part is the threaded shaft. Builing: What immediately stands out is that instructions are more difficult than today. A lot more pieces are added in each single step. Building is going really fast forward, and it's much easier to forget something. You'll see in the pics below, how fast it goes. I have to say, I like that! The sets of these days I often find too easy. After 4 steps: Step 5: At step 10: Step 13: Step 15: Step 18: Step 20: a lot of pneumatic hoses Step 22: Step 24: Step 26: finished the back boom. Step 27: this is already the last step. The complete front bucket is build in this last step :) Finished: First let's compared it to it's newer brother, the Technic set 8455. As you can see the 8862 is a bit larger. Also the difference between studded and non-studded is clearly visible here, but both has it's charms. Also their functioning varies quite a bit. The newer 8455 is completely pneumatic, while the 8862 has only a pneumatic back bucket. The turning of the back bucket, the complete front bucket system and the outriggers are all operated mechanical. Some parts in this old set have already an improved version. For example the bevel gears. The old ones (left) just are not as good as the new ones are (right). Sometimes they just pop off the shaft, and they do not run as smoothly as the new version does. Conclusion Personally, I like the 8455 a little bit more, but this set is also highly recommended! Pros Lots of functions (8 in total) Great playability High nostalgia factor Big model Scale and looks are good Interesting B model Cons Front scope is a bit weak The bevel gears Which set you love the most? -

To get that "first person" point of view in your action videos, do you have ideas on how to mount your video camera or iPod using Lego Technic pieces? This thread is meant to capture those ideas. I know that Sariel likes to mount his video camera on his MOCs, and sometimes he tows a trailer. What are your ideas? Here are two: Method 1: Use Lego Technic to secure your iPod to "Equip your RC Vehicle with a Remote Video Connection" ( by where44444) -- "It started as a useful modification for my RC tank so it could actually be useful in air soft wars. When your out where everyone can see you so that you can see where your driving the tank kind of defeats the purpose. You can now control it from a safe distance and be an active participant in the game through a wireless video connection." Method 2: "LEGO TECHNIC GoPro Mount" ( by Kyle Martin): "In this GoPro mounting tips and tricks video I show how to make a LEGO TECHNIC GoPro Mount. This can be used to mount a GoPro to any LEGO creation. The mount is low profile and will not destroy any of your LEGO. There is another video coming that will show how to mount using just good old LEGO."

Hi all! I'll sumbit my alternate 42004 excavator soon as possible, once I got some time. It are busy days, and making the instructions is more difficult then I tought. Anyway, here is a WIP where that I have been developed for a long time, after my Red Mini excavator. I tought it could be motorized better, or rather remote controlled better at that scale. And we all know: Remote control at small scale = (m)LA instead of pneumatics. Building in 3 or 4 motorized valves isn't feasible in a 12 studs wide space. In the first place I just wanted to do some small changes to my Red Mini Excavator, and 'converse' it into a full motorized version. It turns out quickly the 'superstructure' of that excavator wasn't a good base. It has the same functions as the ultimate 8043, or as many other motorized excavators. -Driving (2 M-motors) -Boom raising and lowering (1 M-motor, 2 mLA) -2nd Section of the boom (1 M-motor, 1 mLA) -3th Section of the boom (1 M-motor, 1 mLA) -Turning (1 M-motor, with worm, gear ratio 1/46,6) As battery box I first tought about the rechargeable Battery Box, but it turned out it was to big. Instead of that one, I used the smaller 9V Battery Box (with the aluminium foil trick for powering the receivers). I hope it will last a little while and it won't run out fast. History: The first thing I did, from the 'conversion' of the prevoious excavator was changing the pneumatic cylinders to mLA's. In the first case I used a single mLA for the raising and lowering of the boom. Later I replaced it with 2 mLA's for a more realistic look. To motorize those functions I had to chose between M-motors or Mini motors . I was in doubt because I tought M-motors are a bit long (6 studs), while Mini motors are only 4 studs long. On the other hand Mini motors are 4 studs wide, while the M-motors are only 3 studs wide. I was afraid the excavator would be too long, because the behind the motors would I need to place the battery box and receivers, which toke about 8-9 studs. I made the decision to use M-motors, to simplyfy the design of the side bodywork. Because I had to place 3 receivers, 1 battery box and 3 motors in the superstructure, the most logical choise was to place the turning motor in the undercarriage. It seems the receivers and their cables sometimes block the turntable, which has 'dramatic consequenses': the undercarriage is pulled apart, trought the worm screw. What I still need to do: -The boom (color, firmness, 3th section) -The weight distribution of the superstructure (so it doesn't 'hang over') -A cabine (at the right scale - any suggestions?) -The turning system (especially the wormscrew) -Give the backside of the excavator a more realistic look (eventually with lights) And to end... http://www.youtube.com/watch?v=tsyRDvk1JaA If you have any suggestions, questions or comments, don't hesitate to say!
