Thank you for suggestion! High five! Front suspension - double wishbone with old gear rack And now some updates: Bodywork almost ready, except rear part and some details. Working steering wheel and 2-speed gearbox and rear limited slip differential in the rear live axle. But I don’t really like the proportions and I don’t know what to do with it TC18 WIP by Alexey Tikhvinsky, on Flickr

Thank you very much for your comments and advices! Today progress is not so great at all, but I'm totally rebuild the front and squeezed the V6 working fake engine into it Now I doubt whether it makes sense to do a pickup wrecker, or is it better to concentrate on something like El Camino

Hi everyone! This is probably my first attempt to make a MOC, not a MOD or something based on Lego set or someone's else MOC. I don't really like this scale, but it's quite a challenge for me to build a 15 wide car Update: I decided not to continue building the pickup. All photos relating to him were moved under the spoiler at the end of this post. After some searches, I find the most perspective prototype: this rat rod. Main goal was not to copy all the proportions, but to keep the visual style and add some nice features. Reddish brown panels and connectors helped me a lot with the first goal. I also decided that the combination of a dark bottom and a white top is funny and it would be nice to name a car like some kind of coffee So, I ended up with this features: V6 fake engine 2-speed gearbox (1:1 and 2:1 ratios) limited slip rear differential working steering wheel detachable HOG steering on the roof ratchet winch (like in 42069) front single leaf spring suspension rear live axle with leaf springs opening suicide doors I'm quite happy about this truck, that was a really nice experience to work in such scale Photos of the chassis and some renders of the drivetrain - inside the spoiler

Sorry for bumping old topic, but I think that making separate topic just for MOD is unnecessarily Main goal was using new C+ motors and hub (to participate in "hill climb" competition in Moscow), keeping in mind secondary feature - low center of gravity combined with weight placed mainly in the front part of the vehicle. I decided that this configuration of motors and battery pack will help in overcoming the slope. C+ L-motor (used for steering) placed between the front suspension arms, under the C+ hub. All 3 C+ XL-motors used for propulsion are connected with two driveshafts (separate for left and right side) by a little bit complicated "gearbox". Main feature of this gearbox is to connect 3 motors and thansfer the torque to the 2 driveshafts (not so easy geometrical solution ). Another feature - "overdrive" function, allowing the front wheels to rotate a little faster than the rear (useful thing for hill crawling) Link to the Studio file So, the green axles are the inputs, red ones - outputs. Blue and dark azure gears are for the rights side and for front and rear wheels respectively, and orange and yellow are for the left side and for front and rear wheels respectively. Orange Pickup Truck by Alexey Tikhvinsky, on Flickr But, I have to admit, the difference in the speed of rotation of the front and rear wheels was too small for me to draw any conclusions about its effectiveness. Final gear ratios for front and rear wheels (including reduction in the new 42099 wheelhubs) is 6.75:1 and 7.2:1 In general, the transfer of most of the mass forward fully paid off. The stability when climbing uphill pleasantly surprised me, as well as the ability to climb with a sufficiently large angle of slope. Unfortunately, the competition did not take place due to the epidemic, and I took apart the truck without filming it, so no videos this time. But that was a nice experiment for me, and maybe I'll return to this concept later. Thanks for watching!

Hello, @Sariel I found some strange bug: If torque of single C+ XL motor = 22 N*cm, then with 36:12 gear ratio and planetary hub it should be 39.6, not 1425.6 N*cm There are x36 multiplier somehere in a code, which is exactly teeth number of the first gear used in the app on the screenshot. Maybe this would be helpful

Thank you! It's never too late to try again! Thanks! I'm very pleased that such a technic specialist like you likes my solutions And it's normal thing! Personally I'd prefer to keep "clean look", but I wanted to try 3rd party tires and this was the only option that fit into the arches, however not until the end (they had to be modified a bit)

Hello everyone! I'm glad to introduce you my tribute to 10187 set! Long story short: I'm a big fan of the ModelTeam series, and always wanted to build a MOC in this style, but I did not find inspiration. And a couple of weeks ago, I found xx1Andi's LDD file with PF modifications of the 10187 set on the Rebrickable. That MOC did not have a front suspension, complex steering system or any other technic features, but helps me a lot in understanding how all the electrics should be placed in the chassis. So I just started building the chassis with a new Control+ electrics, keeping in mind @Madoca 1977's offroader suspension and driveline setup The main goal was to preserve the maximum appearance of the original with the maximum count of functions inside. In the end I was able to completely save the interior, all interior and exterior details and leave a place for 3 motorised functions and manual one. I'm satisfied with final performance: model able to crawl in the forest and even on some rocks. With the help of the winch Beetle can move forward in almost every situation (within reason of course, it's not a lightweight crawler). On the high gear it's fun to see how suspension fulfills little bumps on the gravel road. Red color - dual driveline via 2x C+ XL motors that are not connected to one another, which allows car to simulate open differentials (or turn around like a tank). New planetary hubs can handle with heavy weight (2250 g), even using RC4WD tires for 62mm wheels with the excellent grip properties of rubber. Yellow - steering with a C+ L motor and common gear-rack setup, nothing special. Purple - winch with 20:1 ratio via C+ L motor, capable of lifting a vehicle’s weight on a steep slope or in the air. Winch motor placed between upper front suspension arms, leaving space for some scale details under the hood (like windshield washer reservoir) Blue - torsion bar suspension. 10L axles working like torsion bar with lower suspension arms and limiters firmly fixed on them. Suspension stiffness is adjusted by changing the distance between the arm and the limiter. It's the most simple and compact solution for this scale and weight. Green color - 2-speed gearbox (1:1 and 3:1 ratios) with manual (HOG) switching via small actuator placed between rear suspension arms and driveshafts. Simple and stupid solution - just gears in the frame, that pulls them along the driveshafts with a help of actuator. Nothing special. All these technic parts are connected only by technic bricks and system plates. Mainly by plates There was not so much free space for proper bracing, but some tests and crash-tests shows me that all these system plates are tough enough to handle some jumps. But the main headache was a new C+ hub. That was very hard to hide this enormous brick into the interior, so I was used to make holes in the backrest of the rear seat to fit the C+ hub's "ears". But otherwise I’m happy with the amount of details saved. I love final ModelTeam+Crator appearence Thank you for watching and feel free to leave comments below! Hope you like it! Also you can find more photos here

@desert752 only mistake was to let me drive The only reason for breaking was my driving abilities There was one weak place - steering links, and other chassis solutions can handle much more damage There were two BuWizzes in original setup, but in this video there were four BuWizzes + powerbank (you can see some big ugly rectangle in the "trunk"

Sorry for a little bump =) Finally, I managed to say goodbye to probably the most long-living model on my shelf and I got the opportunity to share photos of the insides. Frame with axles: In general, with the exception of a dozen pulled pins and axles - the frame in the photos is completely self-sufficient and can be completed with any bodywork refinements. Also, it can be considered modular, as it is quite simply divided into 5 parts: the front and rear axles, the middle part with motors and a center differential and two halves of the frame - front and rear. The front axle has undergone some changes: instead of a servo motor, the M-motor with a worm gear +20t gear for steering, the portal gears were slightly changed - now instead of breaking the CV joints on the front axle, 12t and 20t gears just started to crunch (they did not get any sufficient damage after all tests) More photos of the front axle: Rear axle: Motors and central differential: The back of the frame: The front part of the frame (winch mechanism was added, proved to be extremely durable and suitable for the evacuation of even heavy models on the truck trial events: two L-motors, worm gear + 24t gear): In general, the truck showed its best in terms of endurance, strength and driving pleasure, so I think I will definitely return to such a heavy vehicles, especially keeping in mind all this new details from 42099 set =Р Hope you like this beast as much as I am! Many thanks to everyone who supported me while building and modding this truck and a helped with advice or comments!

Thank you so much @imurvai for a new version of your app, works flawlessly with two C+ hubs at the same time! I also have noticed reduced return-to-center speed when using analog stick instead of D-pad, but it doesn't feels critical. The only option i wish to have in the app is a mode, when you can chose limit for servo-motor in degrees or in revolutions. At this moment motor can only work in -360/+360 degrees, but, e.g. when you use worm gear + 24t gear for steering, you have to make 6 revolutions to turn output axle at 90 degrees. Is it possible to add this feature?

Whoa! Such an almighty beast! Instantly recognizable chassis work made by @Toni-23 and clever bodywork solutions from @Aleh. All in all - this is a great truck with nice, aggressive design (very close to original) and amazing offroad performance. Bravo!

Whoa! Another huge truck in my to-build-list! It's very good that the model has less pneumatics, personally I like mechanical functions more Nice to see continuity in your models, they should look good standing side by side

Welcome back, sensei! As much as I liked the previous version of 2016 - I like all the changes in the new pickup! He reminded me of a 2014 Off Road Pickup, but much more compact and much more difficult in terms of features. Great progress over the years! Glad to see you back in business!

Something like multi-staged gear reduction (i.e. in XL or L motors), where gears are small and plastic. Or just trivial plastic gears (4 or 5 in a hub). But these options are weak and I don't think Lego would release such a flimsy product in a "offroader" set.

So, if hubs are just a bit bigger and they still fit into original Lego rims like 15038 - maybe there are some metal gears inside? (that would explain "ball bearing" effect) Or maybe you have another versions?

@jrx, sorry for stupid questions, but I'm so curious So there is planetary reduction drive not in wheel (like brick-built versions based on 48452 part), but in wheelhub? Like modern 23801? And new shafts is like CV-joints for new hubs? Like 32494 part, but larger and stronger?

After 7th January update all problems are gone! Now ports are swapped correct and no more connect issues (4 Buwizzes = about 10 seconds connecting) Thanks a lot!

Same thing on v2 Buwizzes (1st and 2nd ports swapped) Also noticed connection problems with all 4 buwizzes v2. Again, problem was solved on my Xperia XA1 plus with nRF Connect app. Scan and connect all buwizzes with this app - and then start your app and play with all 4 buwizzes without disconnects or lags.

As I previously said IRL - very nice wagon with brilliant PF integration! Maybe not so nice bodywork in rear (especially archs), but functionality of model pays for all the shortcomings. Complicated and instantly recognizable front part, unique front suspension, working fake engine and completed interior - all this things are looking great when assembled in a single model, and full PF motorisation even with gearbox as a final nice touch. Hope we'll see more models from you in future!

Using a technic-brick instead of 1L connector can create an limited slim differential effect in some sense. Maybe there is no sufficient friction difference between this two parts, but when speaking about offroaders, I prefer to create a little bit more friction in a drivetrain (in differentials and after them, i.e. portal or wheel reductors), sometimes it helps a lot in crawling.

Thanks! There is LDD file in main post. And no, Didumos only made LDD and LDraw files, no photo or PDF instructions. Thank you! ? Looks like that was some kind of taxi cab in past ?

Thanks! Yep, there are 3rd party tires, you can find them on Ebay or some chinese online-market. I bought 2 packs (8 wheels) for about 15$ Also this topic is just like El Dorado

And another small update with fun video. Even some easy obstacles can be a big problem when you have 3 open differentials and almost 5 kilograms weight
