Looking forward to check your photos of real-life mockups. Even if you are using some parts unavailable in lego directory, the ideas are universal and can be handy :)

Thank you all. The look sells - literally and figuratively. It is quite clear even observing this technic (in some part at least) forum. But for me functions will be always more interesting and will have higher prio when MOCing than creating maybe super nice looking, but still being just an immovable pile of bricks MOC. That is why I'm still sharing here my MOCs, counting on some discussion about technical aspect of the model, about functions, mechanisms, designing problems and solutions for them. I'm perfectly aware, that everyone can judge if something is nice looking or not. But to judge and to be able to discuss mechanical stuff you need to have knowledge and understanding of it. Without it, any even most complicated feature will be just a next gimmick. I know, that those people with knowledge are rare, it is especially visible on yt or FB, when I see reactions and comments on particular models or functions. Here also those people are definitely in minority, but I think (hope) that this percentage is bigger than on yt or FB :)

Sometimes I forget it is no longer only technic forum :) But I in case of the model itself, it is indeed beautiful shelf model.

For sure I plan to create at least one representative from each type, so one model 4x4, one 6x6, one 8x8 and one 10x10. In addition I definitely will revisit my older MOC - Kirovets K700A - and I'll create it this time with instruction and in proper yellow color :D I'm not sure about scale yet, I'm wondering If I should go with small tracktor tires or to give myself more options and show how powerfull this tractor is by prepering it with middle tracktor tires (from Zetros). Time will tell. And if chapter 6x6 is complete? Yes and no. One thing is the plan I described a sec ago and the second thing is the fact, that I'm very tempted to prepare KrAZ 255 in trial version, so super light, sturdy, with minimal amount of details and functions. Rough power and off-road capabilities, unstoppable no matter what.

Thank you! The rubber elements in the rear are added mostly to limit a little the range of movement and prevent tires from rubbing against 5 stud half beams when tires are in max positions. And I thought it will be some sort of stabilizer when rear tires deal with uneven terrain :)

Hi, I present my newest creation – off-road truck KrAZ 255 version 2.0. This is successor of my first public MOC – KrAZ 255 to which free instruction are available here. The goal in version 2.0 was to improve basically every aspect of predecessor and to pay respect to this awesome off-road truck. And as usual, most of the features are based on truck Tayga 6455B available in game Snowrunner. This truck is also the next part of my Snowrunner series started with Chevrolet CK1500. On the video below you can check what details and functions I was able to put into this MOC and how KrAZ 255 v2.0 deals with off-road terrain and against obstacles. Extensive list of features, details and interesting facts about this creation you can find below the video. Enjoy! Instructions: LINK General details: scale: 1:23 dimensions LxWxH: 42,5x13x16,5cm weight: 1525g Features: 1. RC front axle steering (C+ L motor) positive caster (click) Ackermann geometry almost perfect pivot point (click) PF servo friendly - 180 degrees of movement for steering input 2. RC 6x6 drive (2 x C+ L motor) independent drive input for each front wheel (click) (for this idea I would like to thank @Fluwoeb and this topic, this is because of you! ) rear wheels driven by two independent inputs (one for 2 left wheels and one for 2 right wheels) (click) front wheels driven by one differential and rear wheels driven by second differential (click) both differentials coupled together to harness power of two C+ L motors both differentials coupled with lock mechanisms (click), controlled separately and manually from the cabin (click) and equipped with visual color indicator of diff lock on/off status located behind the cabin (click) power train equipped with new big CV joints - cardans and old CV joints limited in drive of the front axle and completely removed from drive of rear axles 3. RC winch with place to lock the hook (C+ L motor) 4. RC front and rear lights (Lego LEDs) 5. suspension for all 6 wheels (click) front wheels on live axle suspension with shock absorbers (click) and a big range of movement (click) rear wheels located on independently oscillating arms with rubber suppressors controlling the movement (click) rear suspension without shock absorbers - no side leaning and no bending under the load (click) 6. three studs ground clearance (click) 7. bottom of the truck armored with panels to secure crucial mechanisms and improve dealing with obstacles (click, click) 8. two hooks for connecting trailers, front and rear one, both equipped with lock/unlock mechanisms 9. openable doors, hood, tool box, first aid kit, sideboard bed with separately openable sides, each one with two locks 10. working V8 engine with fan which can be easily removed “for maintenance, repairment or for swap” located in detailed engine bay with a grill via which working engine can be watched (click) 11. detailed two seats cabin with openable and usable glove box (click) 12. working steering wheel 13. modular construction (axles, cabin, additions can be easily disconnected) 14. powered by Buwizz 3.0 but also prepared to be powered by standard C+ Hub (click) 15. prepared to be built also with PF motors and PF servo without significant changes and to be powered by Buwizz 2.0 (click) or even standard PF Battery box with IR receivers (click) 16. "disk brakes" in front (click) and rear wheels and many others small details (click, click, click) 17. equipped with many additions from the game Snowrunner, like bull guard, exterior roll cage, roof rack with fuel canisters and spare tire, double snorkel, sun protector (click) Interesting facts, designing decisions and details: driveshafts for front axle are connected in a way that the longer, more “smooth” CV joint part are connected closer to front axle, so lower to the ground, which corresponds with the idea to prepare bottom of the frame smooth and resistance to sticking out objects which can immobilize the truck (click) most of the motors are placed symmetrically at the center of the truck, which is good for weight distribution, but Buwizz unit is localized off centered, closer to the left side of vehicle. To balance that, motor from winch is placed also off centered, but closer to the right side of truck (click) all wheels can harness power from both C+ L motors, as they are coupled, but rear axles, which in general generate more load for motor, are connected closer to the right motor, that is why V8 engine is connected closer to the left motor, which is connected closer to front axle, as the front axle generates less load than rear ones (click) additionally output for V8 engine has the same speed as motor output - which is higher than rest of the drivetrain - for better visual and sound effect (click) there is a „biscuit connector” placed in rear wall of the cabin to increase ways of location and connection and types of power source which can be used to power up the truck (click) to avoid widening the whole truck, only hinges for sides of sideboard bed are located outside of the sideboard bed to allow opening sides to vertical position, which makes loading the cargo easier (click) positive caster present in front axle has (apart from being next feature adapted from real cars, apart from dealing with not very high tolerance of Lego parts, which causes negative caster and apart from being the force which steers front wheels strait when driving forward) a function of forcing front wheels to stay on axles when driving forward (I think this is the answer you were looking for @AutoBacon in this post ) and many more details you will discover, if you decide to build my truck I would also like to thank @nico71 for his great video series related to Western Star 6900 Twinsteer. It helped me to prepare more realistic grill, hood, roof elements and I believe overall better body of the KrAZ than in my first version of this truck. Thank you! Attention! Two C+ L motors with decreased speed 3 times, so with torque increased 3 times, generate a lot of force which needs to be handled by rather advanced drivetrain. That is why there is a risk for 12T gears to skip or even be destroyed if wheels come across too much resistance due to very rough terrain. Please keep this in mind and happy off-roading! Photos: (click) Here you can see the original KrAZ-255 (1211 parts, 991 grams), the new KrAZ-255 v2.0 in standard configuration (1632 parts, 1220 grams) and the fully equipped and ready for everything version of KrAZ-255 v2.0 (2091 parts, 1525 grams): Internals of the MOC, so drivetrain with differentials and diff locks connected with V8 engine, steering with working steering wheel and the winch I hope you like it, if you have some comments or question, please ask. I will happy to answer.

That is why I would paraphrase sentence of popular "orange" president: "Looks good, doesn't work" :D

I like the body, but I wish to know what is the weight of whole truck (even based on program calcualtions) :D Because if you are only planning to driving only on flat, hard surfaces than one L motor will be ok, but If not, then... well :) From my experience, if you pass over 1kg, then one L motor won't be enough for anything different than flat hard floor. And as you probably know, KrAZ is not the typical truck for highway. I'm not sure If you saw this, but such using of connector (6536) will block your axle, one or another. I strongly advise you to check your solutions in real life, it helps a lot and verifying many ideas, good luck! :)

Below you can check blueprints I used. Nevertheless there are very interesting solutions and I'm looking forward to see more. And you should not hesitate to build it in real life, because thanks to my experience with such solutions based on renders I already see what can be a problem when you will put it together :D

I'm glad my MOC can be inspiration for other builders I'm curious what you will create with even smaller scale, but you didn't mention what this scale would be. My KrAZ 255 is 1:23 which leads to 15 studs wide body. This gives me 11 studs of place with standard rims for axles (or as in my KrAZ 2.0 13 stud axles with special rims). From what you write I see you will face or already faced problems I had. I really want to see how you are going to solve them, especially something like this in such small scale :D

Ah ok, you mean THIS diff. It would be so great if possible, but I think it is not. Best you can count on is the normal, standard old DBG one, so nothing special.

But why to care about presence of diff? From part pack point of view - it is irrelevant as this is very common part. From "coolness" pov, yes, it would be a next function, but not very impactful one.

I have a 3k parts MOC - UAZ 3150, and is is quite successful, work on instruction for next one with just over 2k parts is ongoing. But from my experience, if you aiming at financial success, then the look of the MOC is superior over functionality. It is a bit sad from my point of view, as I mainly focus and will focus on functions, mechanics etc, but I acknowledge that this is the reality and I will not bend my aims to earn couple more $. After all designing MOC is a hobby and not what I do for living :D

I admire pricing of this after all nice MOC... I think I will never have as much faith into my creations to put similar prices next to them. But who knows, maybe inflation will eat us all and such amount of money for a MOC will be real :D I'm not going to tell anyone what is correct price for their creations, market will verify profitability of it. Nevertheless, I wish you lack with selling it and I hope you will grow some modesty in you. I realize that most of the people know very less about mechanics, but some people know quite a lot. And if you challenge them, as you did, they will answer. So be prepared.

It looks like superb part pack. I do not care about the model, but amount of new panels is no less than great.

Interesting, for me (considering Technic theme) it looks like this: 2017 - 2 2018 - 2 2019 - 3 2020 - 5 2021 - 6 2022 - 1 2023 - ? So I would say: or 2022 was a year with not interesting Technic sets or I achieved collection which doesn't need so many new "part packs" (but unlikely :P)

The new version KrAZ 255 is finished, so I can also say, that I end the experiment of mine called "preparing WIP topic for MOC". Thank you for all participants. KrAZ 255 ver 2.0 looks like below. I believe, that from mechanical, functional and level of detail point of view, KrAZ 255 2.0 can fight as equals with my other MOC - UAZ 3151. Nevertheless the original KrAZ 255 is still available for free for anyone interested. As this is direct successor of my first KrAZ 255, so I did some brief comparisons on equal terms. It means I removed all additions from new version and put both trucks side by side. Dimensions are almost the same, new version is 2 studs longer and 250g heavier (but it has 2 more motors!). In case of parts count, new version has 410 parts more. Drive train is the most important and the bigger difference between those MOCs. But this is only a beginning of long list of changes and improvements. Space for the engine is the same, but using it is a complete different story. But in both cases there is V8 under the hood. Also space for the cabin is very similar, but many new features found their way into the 2.0 version.

I rebuilt bull guard to be lighter in appearance and to show more of the front of KrAZ. What you think, is it better than old one? I also finished the engine. I was able to add even such small detail like engine oil dipstic.

I have nothing to add here. This is exactly that. I can only say, that this scale forces you to use every cubic stud of space. It's clearly visible on this render also:

Thank you, could you elaborate more about what you think is useless?

I made some progress. Couple of parts are still missing (already ordered) but I think I am close to the end of designing. Any comments, advices, sugestion you have, please share them. Whatever can be improved, I will try to do it. Guided by the game and what can be found in it for this truck I added some necessary additions useful in the wilderness. You can see bull guard, exterior roll cage, roof rack with lights and fuel canisters, tool box just under spare wheel and double snorkels. I also added cargo bed to complete the look. I redesigned front lights to make them more solid and added black background, what you think? I looks better or worse than previous version of lights? Front grill is also changed to be more transparent to let you see even more what is going inside of engine bay. I also added horizontal element to make grill looks more like in the real truck. I changed hood a bit to be more sturdy and most of all not coliding with the grill like previous version. Engine itself was also improved by many elements you can find located next to real engines. I am still waiting for some parts in better colours. If you have some ideas what more can be done, please do not hesitate to point them out :)

At last available for Poland! Order already done.

As requested, I made some tests and it works pretty well considering design choices and complication of drive train. I also made some progress with body work. All your comments are welcome, what is ok, what is not ok and why, what I can add/change etc. Some comments about design choices: - color of the body - I know it is not a blast, but due to used parts and their color availability I am quite limited in this matter - lights are rather simple, but they are ready for LEGO LEDs - roof is ready for some additional lights or roof rack, I will see what can be added - still I am not sure If there should be additional step on the side behind fenders or not (original truck doesn't have them) - I think that system pieces used on sides of the hood can be located one plate lover - cable management is still not done Considering the scale, I think that shape of the body looks quite similar to the original, I put blueprint at the end. More photos you can find here

Hi, is there any reliable way to connect technic part with axle hole with hole in standard 1x2 brick hole? To be precise, I wish to somehow connect this part with this part.

No new parts for Poland also...
