Here's my latest creation, built primarily to put the BuWizz unit to a serious test, and look cool while doing it :) Photos & reading: http://sariel.pl/2017/12/monster-bug/ -
Hey everyone. Sorry I haven't posted in a while, I made something big but it didn't turn out as the best I could do. I didn't want to release a MOC with half effort. Anyway, I started this Monster Truck Van a few weeks ago. I have the chassis basically done and the body is around 60%. It won't have too many functions (just drive and steering), but I want it to look cool and be detailed (roll cage, seats.) Here's what I have so far. NOTHING IS FINAL. The body will be black and will have red accents. I will put the Ferrari rim covers on all 4 wheels. Chassis: Tell me what you think! -
[MOC] Monsrter Truck
Krall posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Yet another moc in small scale, but this time something off-road My goal while building this moc was to implement full suspension + steeringo on both axles, I reached it after just one day of building. Things got complicated when i started building the body for which I had totally no idea. finally i decided to build a blue pick-up truck with some yelow details. I also iplemented two other functions: winch and openable doors. for suspension model uses my own idea shock absorbers, these are really usefull as I believe... I really enjoied building this modeel and I'm happy how it turned out :) some miniatures: Thanks for your atention and I'm waiting for your comments :D -
Hello everybody and let me present my version of a modified 42005 Monster Truck. It was my second set after my "dark age", that I've bought many years ago, after 42029 as supplementary set with a lot of useful pieces and planned to use for a live axle suspension and some other features for 42029 model. However, I liked the set as a simple and functional model and re-assembled it several times. Here is the model and later I'll provide the all details: A month ago, when I tired of infinite attempts to turn 41999 into a Muscle Car (the chassis isn't rigid enough, but I already did a great progress and hopefully will share it once) I returned to this model and set the task to motorize it adding 4WD, but keeping 4 wheels steering and current suspension (keep the original construction as possible as I can). First, I've analyzed the all existing attempts that I could find over EB, Rebrickable and YouTube and it happens that there were several MODs by different authors: First of all, it's @Splat’s MOD with all steered and driven axles (see topic here). I see no reason to duplicate its description, so let me just note that he saved the necessary features with adding Servo + L-Motor mounted under the hood and trunk. The chassis configuration is 4x4/4 or 4WD-4WS. It’s the best motorized model, I think, because of amazing simplicity and performance, but unfortunately it has a kind of “articulated” steering that isn't real, so was trying to made a "real" 4WD-4WS version, using this model as reference. Another one is Jan Dvorak’s (is he on EB?) MOD with all original features supplemented by on-axle L-Motor that drives the rear wheels and Servo for the 4WS. He added an additional 5X7 frame with differential that provided a necessary rigidness. The chassis configuration is 4x2/4 or RWD-4WS. Personally I don't like such a long axle sub-frame. However I've found a good idea of vertical gears inside the central shaft. The third one is @codefox421's MOD, inspired by Splat’s version, with the original front axle and non-steered custom rear axle with on-axle L-Motor. His custom rear axle, based on two portal hubs, is a quite compact and simple, but has no steering. The chassis configuration is 4x2/2 or RWD-FWS. It looks trial-ready with the portal hubs, but it's nearly impossible to add the steering here, so I got nothing from this model. An unusual @Tommy Styrvoky's MOD with an interesting feature: he modified the front axle, not the rear one, by adding a solid drivetrain with worm gear and on-axle M-Motor, so result is a front-wheels driven Monster Truck with oversized fake engine. The chassis configuration is 4x2/4 or FWD-4WS. Very aggressive! WRRRRR Daniel Wirasantosa’s (is he on EB?) MOD that differs from the previous ones by using of chassis-mounted L-Motor that drives the rear axle (that has a bit low ground clearance due to the 5x7 frame) and, moreover, he used a custom steering shaft that comes directly to the steering rack. The chassis configuration is 4x2/2 or RWD-FWS. Starting this version, I got a more or less defined plan: 4WD with off-axle (chassis-mounted) L-Motor that drives the both axles through the existing “drivetrain” (former steering shaft) and the off-axle Servo that steers the both axles through the custom steering shaft above the driveshaft. There were two more versions: Michael M’s stretched one and LEGOTechnic360’s solid-chassis version with no suspension, but they didn't help me with any new ideas. Nothing personal, guys, if you're reading it, I just had a full and consistent vision of my further MOD: Hull - the original with no changes. Axles geometry - original. I tried to save the all things like the wheels location, suspension mounting points, ground clearance, steering angles (that are even bigger a bit now)… And I still can't believe that made it, after a thousand tries! Suspension - original, with no changes. However I put the hard shock absorbers in the rear end, as the default ones were too weak to keep the BuWizz battery. Wheels - original. I decided to keep the original wheels and tires with no giant crawler ones or even Claas, that are too big even for a Monster Truck. Frame - mostly original, but possibly modified since it will have an L-Motor and Servo mounted above the axles (right under the cargo platform and hood). Drivetrain - it must be the ex-steering shaft that comes through the cardans inside the "big" ball joints to the both axles, connected to the L-Motor via the set of normal and clutch gears. Steering - for the all wheels, like in the original model, but the steering shaft comes above the drive shaft, in parallel with it and can slide a bit while the suspension moves. Enough the words...The most interesting part starts here. Following my plan, the bigger challenge was to modify the original axles - I tried several options, even trial-like with solid axles, but 4WS provides an amazing maneuverability due to big steering angles, so axle diffs are likely vital for such model (solid axles were making a permanent clicking noise in the transmission even with motor stalling sometimes) and I decided to make a fast Monster truck, not a slow crawler with a high torque. The drive train. There you can see how I did it: L-Motor rotates a set of 8T and 16T normal and clutch (required for the steering shaft) gears and then the main horizontal shaft, that were used for steering in the original model. After that the shaft rotates the 12T double bevel gears (ex-pinon gears from the original model), than 20T gears below, single-bevel 20T and the differentials. As result, the gearing ratio is 1:1.667 X 1:1.4 = 1.2334, and provides about ~100 RPM with 15.12 N.cm torque. The wheels connected by a wheel hubs, since I wasn't able to use the universal and CV joints with affordable steering angles, wheels position (I kept exactly the same position as in 42005) and rigidness. The steering. Here you can see the servo (mounted upside down in order to provide more space for the battery block above, steering shaft that goes above the driveshaft, 12T gears (pinions) and 13L racks joined to the wheel hubs. In order to allow the suspension travel, the gears has 1/2L offset from the racks and slides together with the shafts along the mounting points when the suspension compresses. It's a fully legal, but still allowed in LDD and works like a charm! The only mistake that the hubs must be from Claas, but they aren't presented in LDD unfortunately: Just to explain why I used the clutch gears (but with no gearbox actually, ha-ha ), the drive and steering systems intersects so hard, so followed TLG way and used the same solution that they did in the official models (42029, for example) - passed the one through the other. Green is a drive subsystem, blue - steering. The Axles. Here you can see how the steering shaft slides by 0.5L (notice the gap between the 12T black gear and LBG liftarm) - it provides about 1L suspension travel for the both axles. Other images, the story of a modified hull (by Phil), LDD file and instruction in PDF are coming soon... -
It's a monster truck with a 4x4 trasmission and 2 speed gearbox powered by a SBrick. This MOC is very powerful because the first gear generates a great gear ratio. The chassis is simply and very strong and the suspensions are attacked to him. I couldn't use the "large hard shock absorbers" because i haven't them, so i used the "small soft shock absorbers". I added a V6 working motor, a rear openig hatch, and lights too! These pictures above are of the old version, in fact the axles and the position of the SBrick in the images are different from the current ones (below). The differential is removable to ensure more traction. The gearbox is very compact and strong (on that I worked a lot of time). The green axle is the input, while the red one is the output: the yellow gears are interested for the first gear and the blue ones for the second gear. The first gear has a gear ratio of 5:1 (very powerful), while the second gear has a gear ratio of 3.3:1 (balanced). The gear ratios were calculated by adding the gear ratio of the all transmission system, ie 3.3. And this is the outdoor video! I hope you enjoy my MOC! Leave a comment and a Like! ;) -

Hello all! Today I would like to share my Bigfoot! Functions: Four wheel steering via HOG at the rear of the cab. Suspension. There is not a great deal to write about other than I'm pretty proud of the nice soft suspension. The only draw back is that the steering circle is HUGE..... The other big challenge for me was getting the yellow and red stripes to look good using only brick built solutions. I'm fairly happy with the outcome. And the real monster! Thanks for looking. Constructive criticism and comments always welcome.

A few years ago I created a modification to the 42005 Monster Truck set, where I motorized it and made it RC (IR), but tried to keep the geometry as close to the original set as possible (see topic here). I always liked the design and size of the body of this truck, so I have used it again, but this time I have completely removed the chassis and the drivetrain, and inserted a new one. This truck uses: the Lego Power Functions Rechargeable Battery (8878) to power an SBrick which controls a 9V Buggy Motor (5292) for drive and a Power Functions Servo Motor (88004) for steering. The truck is controlled remotely using Bluetooth via the SBrick and SBrick Android App on my mobile phone. This truck features: large suspension travel Ackermann Steering and positive caster steering geometry. The tires (56908c03) are the tires that were first seen in the Batman Tumbler set (76023). Even though the wheels are so far apart the truck has a short wheelbase, and thanks to the Ackermann steering geometry and differential in the rear it has a fairly tight turning circle. The front suspension uses a single shock absorber (731c05) with a setup similar to the 8081 Extreme Cruiser set from 2011. The rear independent suspension uses two hard shock absorbers (731c04), one each side. Here's a video to see it in action: Although the Monster truck uses a Buggy Motor, I couldn't give it full power without the battery and/or SBrick cutting power to it. I could only go at about 70% of max speed. I didn't have much space for gear reduction (apart from a 20-tooth gear to 28-tooth differential), so the output doesn't have much torque when using such large tires. Because of this, the truck takes a while to get to full speed, and slows down when hitting an incline or going off-road, which kind of makes the large suspension travel a bit pointless. I might see if I can gear it down some time in the future. I still continue to have a lot of trouble with the SBrick too. I finally have a version of the SBrick Android App that seems to work ok, but despite being only a few feet away and with nothing else around to interfere with it, it would still lose connection with my SBrick regularly. Hopefully BuWizz will be better, and be able to power the Buggy Motor better too. My BrickShelf Gallery with larger images (once moderated) Any constructive feedback/comments/questions are welcome. -
Today I present to you my latest build: a motorized monster truck, still unfinished. Now Finished! Background: It was started last weekend after reading Sariel's book, "Incredible Lego Technic," which featured Crowkiller's monster truck MOC. I looked it up on his website where he had a photo of the chassis and the words "This model could easily be modified to be motorized and driven..." Now you all know what happens next... The Original: Crowkiller's excellent model is a manual 4x4x4 monster truck, with 5 link live axle suspension with diffs, a central differential, all-wheel HoG steering, a fake V8 connected to the drivetrain, and a detachable, and therefore, interchangeable, body. The Motorized Truck: The chassis length was increased by two studs in order to accommodate the two L-motors used for driving. The suspension geometry remains the same, though I will probably have to use the hard shocks... A Servo motor was added to control steering, as well as a standard AA battery box and a V2 receiver. I wanted to keep the central differential, but it would have required the body to be too wide. I also tried to incorporate the V8 engine, but the Servo motor and the steering shaft restrict the placement of gears to connect the fake V8 currently. What Is Planned: 1. A body (or two, or three, or four). 2. Reinforcement of the steering. At the moment, if I crash into anything at speed, (which happens frequently ) the front portion of the axle will bend to the side where the impact occurred. Which is not good. 3. Changing to the hard shocks, as the additional weight is already causing the suspension to depress most of the way... What Is Finished: See below what has been done. Also, LDD file instructions are available here. Photos: Wip MT side Wip MT front Wip MT under The Model Is Now Finished! Free Instructions Are Now Available! Click Here! More photos and information is on Page 2! Monster Truck Thanks for looking, feel free to give your honest opinion (anything from "I love it!" to "Why the &%#@ are you copying other people's work?!" is acceptable ) and any advice you want to. - Leonardo da Bricki -
Good afternoon people. After several mini dark ages, I proudly present my latest creation. The Red Monster! This model came about after trying to get back into Lego via Creator Expert models. Specifically the Ford Mustang and the VW Beetle. I'm usually more into construction machinery, but my last project just couldn't get my creative juices flowing! Anyway, there's not a great deal to say about this model other than I wanted to use the big shocks and have hand of god steering. I'll let the amateur pictures and video do the talking. As always constructive criticism welcome. Thanks for looking! -
I really liked the look of 42005 Monster Truck, but wanted to motorize it. I found Splat's motorized version, which helped kick me into gear and order the necessary parts. Once all the parts arrived from several BrickLink orders, I started thinking: why not try motorizing the model without following Splat's build? Later, I'll tear my design apart and try his build. So here is the result of my tinkering. Motorized LEGO 42005 by niaconis, on Flickr I've been able to retain much of the look (and build) of the official LEGO model. Motorized LEGO 42005 by niaconis, on Flickr The battery box is easily removable and slips into the empty space at the back of the truck for use. Motorized LEGO 42005 by niaconis, on Flickr It is possible to charge the battery without removing it from the vehicle. Motorized LEGO 42005 by niaconis, on Flickr A BricksTer Open Source Bluetooth receiver prototype is mounted to the frame using technic pin/axles and half bushings. I found I needed the bushings because the holes are sized for studs, which have an ever so slightly larger diameter than technic axles. Motorized LEGO 42005 by niaconis, on Flickr A servo motor mounted in the front steers the front wheels while an L motor mounted at the back drives the rear wheels. I wish I could have geared down the drivetrain more, but I found I currently have no 48-tooth gears. Motorized LEGO 42005 Steering Demo by niaconis, on Flickr In the animated gif, you can roughly see how it is steered with an Android phone. And finally, I present a short video showing the monster truck driving around in a local park, controlled by the new proof of concept accelerometer input for the BricksTer Android app (which you can also see in the gif). Thanks for reading this far! I appreciate critique, comments, and suggestions! -

Hello! This is an idea that I haven´t seen before, and wanted to share. It is the 81.6 x 38 balloon tires stretched on the unimog rim. They are 10 studs in diameter and 5 studs wide. The tires will stretch and become unusable on the normal rim after some time! -

Hello there! Here's my little creation - red monster truck. In fact, when I was biulding it, I didn't keep in mind the original red truck by Lego so it was not my intention to make them look alike (plus I don't have any other colours besides red so...). All the controls are manual. Features: - full independent suspension - manually openable doors and trunk - HOG steering - poorly designed interrior with one seat - manually openable hood (via linear actuator) - fake V6 (driven by rear wheels through the differential) The whole photoset is here while here I think it would be more convenient to post only some of them. Thanks.

I've been lurking here for a while but have never been satisfied with any of my MOCs enough to post them here. The nearest I came was an MLRS that worked well but looked rubbish :P Anyway, I'm in the process of designing a Grave Digger monster truck replica (approx 1:15 ish scale). Features: - 4 wheel drive - 4 wheel steering - Steering modes: 2-wheel, 4-wheel, crab - 4-link, very long travel suspension - Suspension travel is also to scale. Almost. - All motors contained in the chassis (no servo-on-axle affairs) - SBrick control - Tyres from a Tamiya Lunchbox I'm designing this in Sketchup and rendering with the Twilight Render (free) plugin. Note that I've drawn all the pieces myself, and they're all drawn to have a low polygon count so that my machine doesn't croak to a halt. Some of the pieces aren't very accurate atm (e.g. the XL motors). So far, I think I've got the chassis designed: And here's a couple of closeups: Issues I can foresee so far: - Friction from so many knob wheels - Bump steer (but I don't want to sacrifice suspension travel by putting the servo on the axle) - Not sure whether having the steering upside down like that will have any negative effects. - Not sure if I can get all of the parts in green that I want Can anyone see any other potential issues with this design (before I start putting in BL orders)? Thanks
