[MOC] Class 1 unlimited buggy
muffinbrick replied to agrof's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Great modification of already great buggy . Original was inspiration for my own build, which is still incomplete, hopefully I'll finish it this year. I also look forward to seeing smaller version. -
It took little more time, but anyway, I've added instructions of both of my GoCart models on rebrickable. Now I'm going to enjoy working on my RC buggy, so hopefully I'll make some progress on it(and share it here) in next couple of weeks.
-
And what about these parts for steering - they are relatively cheap:
-
Tumbler tires are too wide for this vehicle, IMHO. But if you take it just as inspiration, so why not :)
-
Many funny entries :) 22: 10 15: 6 18: 4 9: 3 10: 2 2: 1 Good luck!

I've added Mini Xerion on rebrickable, so you can build it.

Yes, it's directional gearbox for steering. In neutral position it blocks steering arms of rear wheels. Unfortunately this clutch gear has too much play because of those inner "spokes". There should be at least twice as many of them to make this system more responsive. I'm not fan of modified parts, but in this case maybe I sould make exception and add some spokes to those clutch gears.

I wasn't here for a while (again). Thanks for your honesty. I'm still working on that skidder, but there are some complications in that build, that I have to solve, and proportions are the least of them. Anyway, I have all motorized functions done, but they don't work flowlessly, so I need to adjust them. And next step will be complete rebuild of front section. In last three weeks I was working on something else. We had local multi-theme and multi-MOC competion. Here are my Technic MOC built for it: Alternative model of 42035 - Go-Cart Update of 8842 Go-Cart - my main focus was on proportions, including functional motor. Therefore I decided to build it, rather then use actual motor parts. And finaly Mini Claas Xerion. Focus was on shrinking actual model and letting it recognizable. There are most of function present - 3 modes of steering, positioning of cabin and completely functional crane. I also have an intention to make instructions for all those three small models.

Hallo, I've made some digital inspirations for future project of our LUG - MicroCITY. Inspiration comes from existing blocks of flats built in our city in 1950s, modified and adjusted to fit in modules of 32x32 baseplates. Built in LDD, rendered in Bluerender.

Thanks for your reply. I know your buggy, like it, and also my former colegue have it on his shelf ;) It was bit of inspiration on the begining for my build, too. Anyway, I didn't want to copy it, just to make it's performance as close as possible to your buggy, with the same motorization, but in different look and setup. So I would like to avoid placing motors into the swingarms, but rather find another solutions to lower friction. Firstly i want to use small turntables as swingarm pivots and rebuild gears between motors and main axle. Then i will see, if it helps enough, or i'll have to improove it more. My actual build with all motors and full battery box is around 1140g so it looks like it's not that bad, as i thought. I've just made prototype of stiffer rear swingarm with turntable in it looks promising.

As building skidder have very slow progress and is still far from finish, i've started another buggy. It's bigger, have all wheel drive, two L-motors for drive and one M-motor for steering. Shaping is almost done, but performance is poor, so i have to improve it. Firstly buggy is too heavy, i don't know, how to lower the weight of it without affecting stiffnes and look and I'm affraid, that two L-motors will not be enough. Second problem is, that all wheel drive is not smooth enough, there are lot of friction, so I'll have to rebuild rear arms and maybe scrifice front wheels drive. Any suggestions are welcome.

You only need to buy 2 Claases for those 18 missing dogbones ;)

Nowadays I'm working on something different from my previous builds. And also it's "for the first time" in many senses. It's my first attempt to make C-model, first attempt to make motorized MOC and it will be my first above 1000 parts MOC(it's not yet, but it'll be likely). It'll be c-model of 42054, Skidder. My intention is to make 3 motorized functions and some manual functions. Manual functions will be steering by HOG, pendular suspension lifting(and maybe tilting) of blade, rotating and closing of claws, motorized functions will be positionig and extracting of the boom. Today I have main chassis and proportions of model, but it's still bit messy. I have to rebuild front end to make it more rigid and to make manual functioncs work flawlessly, and mainly I have to build rear end with boom and all motorized funcitons.

I've add my buggy on rebricable. Some pics of "final" setup:

Nico71's Creations

Nice car, it reminds me retro-futuristic world of Fallout games(with exeption the fact, that that world was ruined). -
Now it looks way better and should save passengers rolling down the stairs :D
-
Thank you for kind words, I appreciate it . I like your version, this simple decolorization looks very nice! Problem with those 62.4x20 wheels is, that they contact when steered, so this part of the cabin cover should be built differently. I have some ideas how, but I'm affraid that this will weaken construction of cabin, when it is not very strong already. And one more "problem" - front suspension is not willing to return, when pressed. I don't know, if it's only because of weak springs, or if it's fail in this construction . I'll try to replace by as pivots of arms, but i'm not sure, if it'll work. Any other suggestion?
-
Nice, I like this type of machines, and I also dream of building orginal UDS on Tatra chassis. Most challenging would be rotating showel, as like this:
-
Nice performance of the buggy! I think it's too short to make stair jump, but other than that it's very agile. My suggestion is to reinforce rollcage, you should connect those free column ends to upper frame. In video it looked like the cage was damaged by that fall.
-
Thank you for your coment :) I've uploaded LXF here, with updated color scheme as original build with some small changes as you suggested. I think you are right, less is sometimes more and I like it as it is now. Some details are still unfinnished, some unused pins and unfinnished rear safety cage, but all functions are already done. I've edited link to LDD, first one didn't work.
-
I've made some colour options in LDD. Yellow and red would be without any problem, green one would need some small changes because of missing parts in this colour.
-
Small, but important upgrade - HOG and steering wheel. I'm not very satisfied with position of steering wheel, it should be 1 stud further from seat back. Other then that it works flawless.
-
Thanks :) Steering is only by that gear, but I'm just working on it, so it is possible, that today HOG and steering wheel will be done ;)
-
Thanks :) I've made some pics with 62.4x20 wheels and it looked better, then I thought, but anyway, I like those offroad tyres more. And there is problem with bigger front wheels, that they contact side liftarm when steered. 56-ers are also close, but still have little gap there. Here are some pics of rear suspension. I have to replace those yelow beams, which interacts with springs. Substitute them by 2 studs shorter beams will help. I also need to add links to hold rear axle in position, just don't know, where and how to connect them. Colors are only temporary solution, I use parts, which I have in my tiny collection and don't built in other models. When I'll solve all technical aspects, then I'll try to make some changes in colours. I would like to combine black with yellow, maybe with bright green. I don't know, which one will be more realistic yet.

It's about a time, since I've been ended my dark ages and now it looks like my way will be rather smaller attempts and "projects", then bigger and more sophisticated ones. My older builds had their own topics here and here, but I don't think that all of my next builds will be suitable for separate topics, so I decided to make this one, where I have intention to add all of my publishable builds. And for the beginning, here is my wip small manual buggy. Buggies are favourite Technic builds, there are many of them in all sizes, shapes and qualities. This one is intended to be small and simple, all manualy working. Now it has front and rear suspesion, openable cabin, steering and rear wheels conected to fake engine. I'd like to improve rear axle suspension, add HOG and steering wheel and some details here and there. And finaly adjust color scheme, although I'm not very disturbed with this clor vomit in this type of vehicle.
