  2. Here's my latest WIP, the Ram 1500. This is mostly based on my desire to do a vehicle with 8 speeds. Ram 1500 has an 8-speed transmission in reality. The model has several functions in place already: -Steering -Drive (4x4) -Suspension (Front has positive caster angle, rear live axle) -8 speed transmission with 90-degree shift (Not done yet) Here's a picture: Drive is with 1 xl motor right now, but it will be changed to 2 as 1 does not have enough torque for gears 6, 7, and 8. Steering is with 1 m motor. The front suspension has a positive Caster angle. It was built by angling the suspension beams and securing them to the chassis. The rear axle is incredibly weak right now. PLEASE LEAVE A SUGGESTION FOR OW I CAN IMPROVE IT. Here's the gearbox up close. The entire section of the chassis is extremely dense, but the is no gear slipping when driving. Please leave a suggestion, and I will update the thread soon! Thanks for your attention.

  3. - this is not to be taken too seriously - Okay, it's been over 30 years ago, but it's still bothering me. Time to come clean . I have cut my own 3L axles, I have made a constant-velocity joint from two U-joints and I even made my own crankshaft and pistons ! I'm sorry, I will never do this again . I hope you can forgive me! PS If you want to come clean too, or just like to confess your Technic sins, please confess them here.
  4. Hello everyone, I have recently picked up a 42054. Immediately I noticed the insane amount of backlash and resistance in the steering system. Here's how I fixed it: 1: Finding the problem: The problem was one of these: It was adding lots of friction which caused the grand majority of the backlash. It is added in this step (step 57 substep 2): 2. Replacing the piece. This was relatively simple, I replaced it with one of these: I had to hold the other piece in before placing it into the assembly, but it was totally worth it. There is little to no backlash and resistance. So, that's it! Thanks for reading! BrickbyBrickTechnic
  5. Hi, This is my new MOC which I have been mostly working behind the scenes on (and waiting for BrickLink orders) and it is finally finished! I am not sure what to call it let me know if you have ideas. Hope you like it! Video coming soon.
  6. Hi, I decided to make my own supercar after seeing numerous topics. My current chassis has a 4-speed gearbox and independent suspension.
  7. Technic General Discussion Welcome to the Technic General Discussion topic. Here you can post small questions or comments about Lego Technic which don't need a topic of their own. This way we will keep the number of topics limited. Examples Has anyone built vehicle x? Where can I find this or that? I missed this set on eBay...darn!
  8. Review: 42065 RC Tracked Racer Name: RC Tracked Racer Number: 42065 Theme: Technic Year: 2017 Pieces: 319 Price: USD $??.99, Euro 79.99€, AUD $119.99 Brickset: Extra Info Technic Early 2017 Review Series Welcome to the second in my batch of 2017 Technic reviews! I was offered all the small sets early 2017 for review late last year... but I ended up getting them all! Thus I have a lot to review. I've been doing them in parallel and changing my process as I go so hopefully the latter ones will end up being the best. On that angle I'll probably retcon some of the earlier reviews if I improve my process. Due to this remember that I'm happy to take extra photos or provide extra info on request, and anything especially good will be added to the main body of the review. Do note though that sometimes the model may no longer exist if I have have made an alternate. On the subject of alternates, I will be making the alt model, if I have the instructions, think the model is worth making, and I have the time. Also I'll show mid stage construction only if I think it's relevant. Thus don't ask for construction photos or alt models if they aren't part of the review.... I am prepared to extract parts for detail photos though. Photos will all be hosted on Flickr so larger versions are available, and relevant videos will be on YouTube and linked to from here. I don't edit photos much; very rarely I'll crop one and almost never will "correct" them so the photos should be as natural as possible. I will try to not be repetitive; thus it's worth reading my other reviews. For example I'm not going to complain too much about the digital instructions; I'll try to complain about new things, or maybe not complain at all! Here's all the other reviews of H1 2017 Technic... 42057 Ultralight Helicopter 42058 Stunt Bike 42059 Stunt Truck (and 45058/42059 Combiner) 42060 Roadwork Crew 42061 Telehandler 42062 Container Yard 42063 BMW R 1200 GS Adventure 42064 Ocean Explorer 42065 Tracked Racer Mucho multi thanks to the EB LUG Ambassador CopMike and the LEGO CEE Team and Designers for allowing me to review these sets for Eurobricks. So onto the review! Packaging Front.... ...back.... ...top. Unboxing Standard punch box. Only one instruction book and it's staple bound. Secondary model has instructions online only, at this stage it is not there. Not a big fan of the whole on-line instructions system. There seems to always be a delay in the release of the secondary model, and the app does not support all devices. For example my Xperia Z5 is not compatible, but my Xperia Z Ultra (older but larger screen, but a phone, not a tablet) is not. The build is not sectioned. In hindsight I probably should have left the tracks bagged for this photo. The special parts being.... ...the anniversary part.... ...and the recolour of the track sprockets (If I'm missing any please tell me!). Parts list. Random instruction page. Build It's done! Spare parts. The model opens up nicely to reveal easy access to the battery box top... ...and bottom. As a result you don't even need to remove it to replace batteries; you can just slip off the covers. Oddly though there is no way to clip down the body; it's held in place by gravity only. You can see the anniversary part here at the rear. Inside there isn't much; the motors are directly linked to the sprockets... ...and aside from the benefits tracks give, there is no suspension. Since this is a Remote Controlled Racer by name, I decided to make some videos highlighting its capabilities. Adding the stickers does help blend the panels together. On the subject of aesthetics, the "antenna" is an interesting addition. Since it's not really a RF car it has no purpose except making it look like one... thus does this make the set a model of a non-LEGO RF tracked model, or is it deliberate deception? I should ask the designer I suppose... No "Octan" sticker to my disappointment. Only companies like "Roaring Motors", "Fat Tyres", "Acelle Rate"... Ratings Function: It does what's on the tin... but pure motor vehicles I do have trouble seeing as "Technic". Afterall, back in 2008 there was a Mars Mission model that was designed to be motorised and mechanically was much the same; the same motors directly driving the sprockets. Sets like this would have normally been grouped in the "Racers" line. 4/10 Parts: Once again, it's as advertised. There's pretty much little functional Technic, but it is a RC Track Vehicle so faulting that isn't fair. 9/10 Price: $119.99 AUD for 319 parts seems rather bad, but in reality the value is very high due to the motors; individually the Power Functions cost $95 AUD. 10/10 Accuracy: I could fault the asymmetrical motor placement, but I think the design is intentional to reduce width and increase balance. Which is arguably an accurate decision since this actually has to move, which it does very well. 9/10 Fudge: What we have here is the ultimate design-your-own-RC-tracked-vehicle set. Technic it may not be, but it is pretty cool. 5/10 Overall: Buy! 7/10
  9. Hello everyone! I present to you the first ebouch of work that will occupy this summer: a recycled truck of European type. At the exit of my dark age this was my first subject that I treated in lego technic. The model of the time had a awful design and many (too) features Here is my program for this model: Its scale will be granted to my latest creation. Size medium. No RC on this model The manual functions will be the steering on two axles, already realized and functional, a fake engine V6, already realized and functional, a cabin liftable. At the powerfunction level, I will use a simple medium engine coupled to a reverting gearbox for four functions. These four functions will be: the rear loading of the trash bins, a compactor with two synchronized movement, the lifting of the rear part (compactor) and a scissor ejector. The ultimate goal is to have a model that can be left without worries in the hands of a child. The carrier frame is fitted and already shielded for this purpose. At the level of functions I will use mini actuators and for the compactor a system that I still have to test but based on what is done in GBC. Here are the first photos of the current progress, I will post the update as and when progress. Your comments are welcome. As you see, the build is not symetrical. Fuel tank on one side and fake compressor of the other side. The lighting is already incorporated. Placing it later is one mistake i will never do anymore... To be continued...
  10. Jan-'17 Now, building instruction file (PDF) is available at Rebrickable linked below http://www.rebrickable.com/mocs/Modoro/motorized-42056-porsche-911-gt3-rs-version-11 ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Hi.. everyone! This my 2nd posting here, introducing my own renovation(or remodeling) of TECHNIC 42056 PORSCHE 911 GT3 RS. Among the newly released 2016 Lego models, "TECHNIC 42056 PORSCHE 911 GT3 RS" received the best attention before release. In addition to its nice and detailed appearance, now I attempt to review the process of blowing features including RC driving and 4-speed gearbox shifting, and LED lights as well. The video above shows the process of remodeling TECHNIC 42056 PORSCHE 911 GT3 RS and a driving test in the following order. The process of remodeling each part of PORSCHE chassis Driving and steering test of the remodeled PORSCHE chassis The process of binding the renovated chassis to the PORSCHE body Field driving test The main target of this RC remodeling is just a chassis (or power-train) that is composed of front/rear axis, power transmission and steering units. The following figure compares the before and after appearance of the renovated PORSCHE chassis. <Before> <After> The changes and features of the renovated PORSCHE chassis are as follows Mounted drive motors (L-motor x 4) Mounted a steering motor (S-motor x 1) Modified gear shifting method not using the paddle shift remodeling of the 4-speed sequential gearbox for enhanced durability and power transmission efficiency Mounted PF battery (optionally, two batteries) Mounted two SBRICKs for the remote control capability While including all of the above modifications, it maintains the design and major features of the original 42056 model. (rear fake engine room, Hand of God, glove box, toolbox under the hood etc.) This review is divided into a total of 9 sections, and the following videos illustrate the building progress of each section, respectively. part 1: chassis frame remodeling In this section, the main contents of RC motorizing 42056 PORSCHE chassis is largely divided into three sub-parts and will be described as follows . 1) reinforcement of chassis regidity A dictionary meaning of chassis frame is defined as "the frame plus the "running gear" like engine, transmission, drive shaft, differential, and suspension" In the original 42056 model implementing the real PORSCHE 911 GT3 RS in LEGO model, a chassis is composed to support the body, transmissions, front and rear axis, engine etc. By the way, LEGO designers did not consider the RC driving from the stage of planning the TECHNIC 42056 model. Thus the chassis regidity, weakened by adding driving & steering motors, gear-shifting motors and battery boxes, cannot maintain the body shape of its own secure and inhibits the stable driving performance. In order to reinforce the chassis regidity that is more weakened by removing liftarms to mount 4 driving L-motors under the gear-box, 42056 chassis core is newly configured using a total of thress TECHNIC 5x11 liftarms. 2) provision of driving motor mounting space 4 driving L-motors are mounted under the gear box between the driver and front passenger. 3) provision of gear-shifting axle mounting space In the original 42056 model, The transmission and drive shaft axis are designed in the form perpendicular to each other. According to this design, gear shifting can be done accurately, smoothly and sequentially from 1st speed to 4th speed. However in the driving test progress, it turned out that thress 24-toothed bevel gears in driving pathways can not deliver high torque & power to the rear axle and differential gears. Thus, to remove three bevel gears in the pathway of the remodeled 42056 chassis, gear shifting axle is heightened by 3L and driving shaft is connected right to the 4-speed transmissions. part 2: 4-speed sequential gearbox remodeling part 3: control units for the RC gear shifting part 4: driving motors mounting part 5: dashboard remodeling part 6: front/rear axis remodeling part 7: rear engine room remodeling part 8: assembly process of the renovated PORSCHE chassis part 9: binding the renovated chassis to the body of PORSCHE These are all I prepared for the review of the motorized 42056 PORSCHE model. Thanks for reading & watching (-;
  11. I have not seen a topic on this, so if there is, please do move or merge with an established topic. Which AFOL community builders' work do you like or inspire you for your own projects/creations? For me, there are many, but my two top favorites are JonHall18 and Vince Toulouse on Flickr. I think they both are the best builders in the Dieselpunk and Sky-fi genres (both favorites of mine), and Vincent's artistry with Lego parts make unique and fantastic art deco-esq vehicular craft. https://www.flickr.com/photos/vince_toulouse/ https://www.flickr.com/photos/25163007@N07
  12. I haven't posted any model here for a long time so let me introduce you my latest alternative models built out of set 42060 - Roadwork Crew. The first of them is Formula 1. It has pretty low functionality (just "hand of god" steering) but at least I've made something original. :-) Most of formula is only 3 studs high so it was big challenge to squeeze steering in it. Another alternative model is Propeller plane. It whirls its propeller when you're moving it around. This model is literally full of "crazy" building techniques because I had to connect together all those liftarms going in different directions. I've built both models for competition in building alternative models out of set 42060. If you wanna see what other competitors built, check this link: http://www.kostky.org/forum/index.php?topic=50909.0
  13. Hello everybody, This is my first post here, although I have been a frequent visitor for a while. This is the MOC that I have recently been working on - a 2014 Ford F-150. Features: - 4x4 drive through 2 XL motors -Steering through M motor (will be connected to steering wheel when finished) -Opening doors, tailgate, bed toolbox, and hood -Front winch -Full suspension -Front and rear lights Some pictures: The two front doors, the winch, and opening hood are all powered by an M motor run through a distribution transmission. The three functions are controlled by a servo motor: neutral position (shown in the picture) opens both doors simultaneously, rotating one direction operates the winch, and rotating the other direction will open the hood when it is finished. In the picture below you can see the driving rings of the transmission and the servo motor above it. For me, designing this has been the most fun and challenging part of the model, if any of you are particularly interested I could make a short video about it. The interior and the front end still need a lot of work as you can see. Additionally many exterior pieces around the cabin are not the desired color. I am hoping to get this finished in the next couple of weeks, at which point I will make a final video showing the functions. Of course any suggestions would be greatly appreciated. This is my second large scale MOC (the first one was a dodge challenger that was not very well done imo and has already been destroyed for parts). Hope you guys like it!
  14. Inspired by Akiyuki I've designed the below GBC called Rainbow Wave. It has 38 Lego colors and about 1150 moving parts. It is powered by a single motor, with each of the colored pistons sitting on an 8-tooth gear. Each piston’s gear is exactly 1 tooth offset from its neighbors making one wave 8 colors. The GBC is level so the balls are moved by the waving surface. The Rainbow Wave is on Lego Ideas: https://ideas.lego.com/projects/169256 I've also modified the Akiyuki Marble Run to a stand alone GBC module by shooting up the balls on the inside with two wheels rotating at about 1000 rpm. There are 63 pieces of 32L Technic flex tubing in it , that's 16 meters. On my Flickr you can find pictures of the modules https://www.flickr.com/photos/r53/albums/72157674088455954
  15. Hey everyone! Finally found some time to shoot a video for my second spirograph. I actually had this finished over a year ago but you know how life works sometimes:) Thanks to PG5200 for describing to me how his V5 works which largely inspired this one. To address the question I get asked all the time at exhibitions "Can you get two going at once?" I came up with this: These are drawn simultaneously, which you can see in the video here: Thanks everyone:) I'll have an LDD file on the way shortly
  16. Please support on LEGO Ideas if you like this project! If you remember those little clockwork robots, which used to be toys and are now prized collection articles, than you will surely recognize my representation! I've been working on this for some time now and I'm proud to say that this robot walks as well as the real thing! It uses two pullback motors, a couple cogs (gears) and 623 LEGO elements to achieve (I only hope you agree ) both good looks and great functionality. The mechanism with the incorporated motors is made to fit exactly into the case and the case comes off all in one piece (I like my modularity). The mechanism for the legs is the most simple thing ever but making it was as complicated as any of my larger MOCs, because balance played such a vital role in all of it. You can still see it wobble as it walks (I find the wobble quite indearing though ) and a lot of work went into keeping it from falling when it does. I like to think this is my best work yet, so I hope you like it just as much enjoy!!! My Flickr gallery I'm not sure if anyone's seeing this video at the bottom of the page, so I'm editting it in up here... Please support on LEGO Ideas if you like this project!
  17. Hi all, This topic is for discussion of the new C-Model Index (under construction here), and for suggestions of C-Models for inclusion. I hope the index will help us all keep track of the great C-Models people have created, and in many cases, their instructions. I've managed to find a good collection to get started, but no doubt I will have missed some, so please tell me any you'd like to see added (or any mistakes/missing details/etc), and I'll add them in future updates. Rules for inclusion: Uses parts from only one set; That's about it! Where possible, I'll list details of EB topic, youtube video, instructions, and part count. Models detailed on EB are obviously favoured, but I've already come across one or two from elsewhere which I feel deserve to be included. They are listed in no particular order. Where individuals have listed their creations as C-Model, D-Model, etc, I have ignored this and called them all C-Models, because each designer's classification doesn't work when all compiled together. To keep this manageable, I'm going to try and release these in groups according to the original set. To start with, here's all the C-Models I have managed to round up for the set that got me out of my dark age - and perhaps its no surprise, given the sheer number of useful parts: [EDIT: moved 42009 into the index.] Hope this is useful - suggestions welcome.

  19. DISCUSSION TOPIC (THIS IS NOT THE HALL OF FAME!) Welcome to the Technic Hall of Fame Discussion topic. Recently, we have created the Technic Hall of Fame! The Hall of Fame is used to eternalize some of the amazing MOCs created by our very own respected Eurobricks members. Criteria When will a MOC be added to the Hall of Fame? Frontpaged MOCs will be added to the Hall of Fame Contest winners Possibly some older iconic MOCs When it fits the "Could this be sitting on Blakbirds shelf?!" criterium MOC needs to have it's own Eurobricks topic MOC should have it's own Eurobricks topic submitted by the builder of the MOC MOC needs to be Technic, Model Team or Mindstorms Jury Who decides which MOCs fit the bill? Models will be elected by Technic staff members and some gifted builders (whose identities will remain unknown), known as the Chosen Ones Suggestions can be posted in this topic, but ultimately the jury decides Update frequency When will the Hall of Fame be updated? There's no fixed time frame It can take a while between updates (adding entries) How New Entries Are Added The editor will first make place holders, he adds new entry's in one big clump (when time is available). The editor prepares the new entry's in advance on a secrete part of the forum. You will be (or should be) aware that the forum has a time limit that needs to be reached in order to make a separate reply and not to merge with a existing reply if it is the same forum member , this means that each new entry gets post separate reply. This also allows the editor to link to that reply directly. Guidelines I know these guidelines might sound a bit harsh or unfriendly, but I hope you'll understand that they are necessary, in order to make this work for everyone, and for staff members in particular. So please refrain from: Sending suggestions via PM to staff members (we read the forum too, we'll see great MOCs) Elaborate debate with staff members (I like this one better than that one, so why is it not in the Hall of Fame?) Asking questions like "when will this MOC be added?" Asking questions like "why hasn't this MOC been added?" Suggesting of hundreds of old great MOCs So am I even allowed to do something in this discussion topic?! Of course you are! Have a civilized discussion with other members (and staff) Suggest MOCs for the Hall of Fame. Post ideas and suggestions about the Hall of Fame setup Hopefully we will have a great Hall of Fame for the years to come! NOTE When posting suggestions.... PLEASE ADD AN IMAGE AND LINK TO EB TOPIC TO YOUR POST!!
  20. What started as a basic color change of 42036 to red, quickly turned into me building my ultimate superbike. Something close to the 1299 Superleggera or Desmosedici RR. Just clean lines and simple functions, although I'd like to add a gearbox but space is tight - Single-sided swingarm - Drive chain moved to the inside - Front/rear fenders added - Dual-shock rear suspension - "Carbon" rims and brake discs w/ calipers - Radiator added
  21. Could we see a future recolour of this upcoming real life car in Metallic Silver?
  22. I'm unsure whether or not I should be posting this in this list or on the Technic list, but I guess that it's more topic-specific here. There are a lot of vehicles over on the Technic list, and that's fine. Technic LEGO probably best lends itself to constructing vehicles of various types and there are many fine and talented exponents of that art over there. But I did start wondering what else might be made from LEGO Technic; something without wheels, motors, PF or remote control. After a bit of a brainstorm my mind settled on the good old-fashioned mechanical signalbox lever frame. There have been very few previous attempts at such a build (at least as far as I can tell from my research), so I thought it would be interesting to see if I could make some headway. I'm not terribly technically minded, but this was something that I do have a reasonable understanding of, and it's complicated enough to be challenging to design and build. The starting point was to make the model fully functional and as realistic as possible, which means that any notions of scaling correctly would go out of the window (luckily that's an approach I'm very comfortable with). Therefore I wanted not just to have the lever frame but the interlocking frame too. Sadly Technic does not lend itself well to the conventional tappet method of interlocking, so I would have to devise my own system that did suit the medium better using sliding bars with pegs engaging with holes. I also wanted to include the catch plate mechanism on each lever. Fortunately for my sanity I haven't kept a tally of the number of hours I spent brainstorming and then trying things out in LDD. As I said I'm not the most adept at technical matters, so this really has been a labour of love. However, I got there in the end and came up with a mechanism that looked good in digital form. Having done so I cast around for a prototype that I could recreate and settled upon Downham (the station is now called Downham Market, correctly reflecting the name of the town) between Ely and Kings Lynn in Norfolk as it was around 1974. It's a modest frame with 22 operational levers at this stage operating both points and signals. Downham at this time still had both an Up and Down yard as well as privately operated sidings, so it's an interesting location with lots of operational potential. This is the LDD render of the lever and interlocking frames without the locking bars. My poor little netbook couldn't cope with the whole thing in one file so each had to be designed separately. And this is the completed frame. It took a day and a half to assemble and, while 22 levers sounds quite modest (and is when compared to other locations on the network), the actual result is a bit of a monster. It looks more like a Wurlitzer organ than anything else. A close-up view of the interlocking system. You can see how it should work with the pegs engaging with holes to either lock or release levers in the frame. The idea behind interlocking is to prevent collisions and other mishaps on the railways by physically stopping the signalman from operating certain points or signals. This is the catch system on one of the levers. As is the case in a real signalbox, the lever must be released from the catch plate by operating the handle at the top of the lever before it can be pulled. A signalman would be familiar with the position and function of all the levers in his signalbox, but just in case each one is colour coded (as per British practice) and identified by a plate. There's more on my Flickr page. So, does it work? Well, yes and no. But mostly no. The catch plate system works brilliantly. Admittedly because it uses a rubber band it can be forced, but it's not easy to do so. But it's in the interlocking frame where things aren't so great. Part of this is because I designed the frame to be modular so that it can be expanded as required. A small prototype frame lead me to believe that the level of flex would be acceptable, but it turns out that at full size the flex is a significant problem. Luckily I designed the frame so that it could sit on baseplates which will almost completely eliminate flex altogether, and so I have some on order. But the biggest problem is that the various parts of the interlocking system need to stay perfectly aligned in order for it to work properly, but they simply refuse to do so. Levers that are meant to be locked can still be operated while others that are meant to be released remain steadfastly jammed because the locking bars do not move as they are designed to do. Part of this is because the friction in the system needs tuning (for which I have replacement parts on order) but mostly because I underestimated what would be needed to keep all the parts in correct alignment. Therefore I've had to design structures to add to the frame that I hope will keep the various parts in line. The locking bars themselves still require a redesign in order to work with these modifications, but that is next on my list. Hopefully these remedies will be enough to have the frame working smoothly. If these fail to address the problems the next area of attention will be the sliding bars that drive the interlocking frame. After that I'll be out of ideas. I hope you like it. I'm having a lot of fun with it and am proud of what is my largest MOC to date. There are more updates planned which I hope to reveal as time goes on.
  23. I present to you my Lego Technic Chilli Crawler! This is a complete makeover and overall improvement from my previous Carrot Crawler: http://www.eurobrick...howtopic=112037 Yes, I know. This is the second crawler that I named after a vegetable; expect more! Features: - Triangulated 4-link live axle suspension using 4 soft, black shocks. - 4x4 with one PF XL motor mounted parallel* to each of the two axles. A final gear ratio of 1:5.001, yes this may seem slow, but the enormous Super Swamper tires make up for it. - Speaking of that, 4 RC4WD Super Swamper tires. No, they are not Lego, I got them from a nearby hobby shop. - One L-motor for steering in the front axle, geared down via worm gear to 8 tooth gear, then a 12 tooth gear to a 40 tooth gear. The 40 tooth gear drives another 12 tooth gear that moves a 13L gear rack. - Portal hubs for all four wheels. Standard Lego Unimog for the rear axle for rigidity; custom triangular plate portal hubs on front axle for a steering pivot point closer to the center of the tire. - Good articulation, about ~55-60 degrees. - Controlled with an SBrick. - Powered by a Lego rechargeable LiPo battery. - Green Chilli Stem** * The mounting of the drive motors parallel to the axles was a must for this crawler. By doing so, I have not only eliminated gear slippage as there are no perpendicular gears, but there is also a ton more ground clearance in both the front and rear axle. The rear axle especially as the motor is actually on TOP of the axle. Crazy, huh? ** Makes the crawler look so much cooler. Challenges: - As with all 4-link suspension setups, the mounting and placement of both the links and the shock absorbers proved to be a rather annoying, tedious part of the process. I have, however, managed to make a VERY rigid triangulated setup where the shocks are not bent or warped in any way. - The mounting of the two lower links on the front axle was also difficult as there was virtually nowhere I could mount these links onto. I was able to (somehow) securely mount both the lower links and the shocks of the front axle onto 7L and 9L beams on either side of the motor. - Mounting the motors parallel to the axles proved to be hard, but actually somewhat straightforward when it came to the rear axle. I had been so used to having drive axles perpendicular to the axle like on my previous crawler. The mounting of the front drive motor was difficult in the fact that its power is transmitted through various gears and the motor itself is connected to the axle by two plate beams and a pin or two. Although the front drive motor is still not completely rigid, I have had no problems with gear slippage whatsoever in either axle. Some pictures: And finally, here is the youtube video: I welcome any suggestions or comments you may have. I will, however, say in advance that I DO NOT plan on making a body for this crawler as I designed it for performance purposes mostly, a Lego "comp-crawler" as you may call it. Thanks, pt

  25. Ive just assembled the arocs mercedez truck. Wow its big but the pnematics dont work at all. Pumps on, slight movement but not enough power to lift anything. How does one know if the pump is putting out or mal functuioning or valve mal functioning. Im frustrated a bit. Seems at best the pneumatics system is weak to begin with. Do the little blue pumps often cause trouble. It is a new set. Thanx
