do you mean we should not say anything against any model/design shared here in this website? cool. have fun. it is against my principles with lego but definitely not with yours.

I dont want to sound so negative but is it considered legal? both shifter and switcher? did lego use those solutions in a set yet?

I thought it was opposite in general community. I mean new parts are welcome as long as they solve problems about stress, stability or they are innovative. this is a distinction on who is building, casual or pro. if you are a casual builder (like me) then I do not lose much and also I do not go into unnecessary faulty designs because I can see it is not working. A pro like you guys would go forward with the idea and spend months perhaps to solve it. I think Sariel mentioned it above already. he would fix his MOC in a day and move over in old days but maybe he would spend weeks for small improvements now. I would not, I am not going that deep into my MOCs about perfection. it is a hobby and not everyone checks details as you might think. functionality without problems or no illegal movement is enough for me and I would not be demotivated because a new piece comes and solves the complex problem nicely. I would be demotivated if new pieces about RC stuff comes or panels comes, or unusable colors for me. it all depends what you are looking for. maybe a pro would like different colors/panels more, I dont know. to be honest at every new piece introduced (not panels) I would again get motivated and try to buy it (bricklink or lego shop) to build something, use that new piece. is it frustrating? yes, but demotivating? not at all, it is opposite for me in general. example: I always wanted to build a large scale borderlands vehicle and I was thinking of 9398 tires. I dumped the idea long ago, I did not like the tires. then the claas tires came out and I started axles immediately after buying those tires from bricklink. same with 3L driving rings, sliding connectors inside it, porsche wheels, black wheel hubs and chiron orange gear switchers. if those new pieces do not come up then you have to repeat yourself at every year and the hobby shall become extremely boring.

worst comment ever. that is what others above talking about the opposite. some people claim and even link to topics that got few or zero attention and you say a good MOC always gets a proper attention here? oh, nice to hear all these guys' and also my MOCs were trash too.

yes, you have to be very specific on searches. but not many people search for that (the slipping torque of the clutch gear), right? how many would search complex lego machinations nowadays since the sets are getting less complex? they search for ferrari MOC, or lambo MOC or car MOC. the trend is cars, not complex or awesome stuff. first thing I built as MOC was a car of course, and I would search for car MOCs for sure. EB has many old and outdated stuff, I would not rely on a few years old stuff I find here; re-asking is always a better idea if you are involved in lego for a long time. TLG introduces new pieces every year and some designs become a lot different, simple and sturdy now, in most cases. that is why https://www.eurobricks.com/forum/index.php?/forums/topic/175235-help-generic-building-help-topic/ seems a better idea than old long-forgotten topics for hard-to-find-elsewhere information. And it is very new, Jim started the topic this January. I do not know which is best for sharing such information though, I believe it is a good direction. search for gearbox of a car now (quite common topic I guess) and old topics found are not very relevant anymore with the switcher mechanisms changing. search for ackerman steering with old hubs (8070, 42000) and todays black hub, even the crawler's hub; the results are very different. search for telestopic arm for crane, pre-42043 solutions are old now and in some cases new solution is better, depends on scale and size. if TLG introduces a new design with new pieces then not many people shall focus on the old design anyway. I left lego after I bought 42056, paddle shift was a big change for me, perhaps everyone. I followed MOCs and almost every new model had those. paddle shift and sequential gearbox. then with chiron the orange switcher came (it was with chiron, right?). majority of people moved over to sequential gearboxes and now people are making 8gear ones (sorry, I forgot designer's name but posted here). if TLG introduces a new brake system for their new 1/8 car then forget all pneumatic brake designs from old topics here. no, I do not rely on old topics I find here. it really depends on what you are looking for of course. topic is about MOCs, yes, we want those shiny good MOCs.

I agree on first part. second part about awesome MOCs, well most of them are on sale now, and they are also posted here. I see many technic MOCs on other sites. I still feel it is something with what those sites offer. they offer something else than what this site offers here and people want that instead. it is like losing to a competition. more appreciations/recognition could be something but I do not think it is the main reason. remember the time about latest contest? it is something other sites do not offer so we saw many MOCs. was not it a record of contestant numbers? but if you do another contest of building ships/boats would we have that many contestants? I do not think so. I feel the problem is not a single factor. it is combination of many things happening at the same time. different sites for different purpose and gains, technic part limitations (getting closer to roof perhaps?), (reduced) complexity in sets which makes people to produce less complex MOCs, cars cars cars because people like seeing them, pandemic impact on lego which is expensive for some people, chinese stuff and so on... if one of these hits a MOCer then you lose one (in my case). other people might be hit by something else maybe a mod can have a look on if site has a decline on visits/posts nowadays. maybe the problem is elsewhere. I searched for "lego technic MOCs" and I did not see this site on google's first page. this should be treated as a hint perhaps.

so true. you can see many MOCs posted there, but not here. paid MOCs at rebrickable or chinese pirated stuff seems the future, unfortunately. if you see your instructions for that model exceeding 3000 piece which you spent hours to build, sold elsewhere you might think otherwise. I also had three WIP MOCs but when I saw my MOCs sold elsewhere I gave up Lego for now. it is my personal demotivation, maybe others might have other issues like pandemic, loss of jobs and change of life.

I hope not, I would prefer other colors. also why do you say 2022? we had 42110 at 2019 and Lambo at 2020 so why not another big licensed set for 2021? maybe Ferrari is a set to align with Land Rover but not 42096? is Land Rover not considered UCS?

looks very disappointing that there is nothing worthy unless you want cars. I also do not think they shall have any special/unique mechanisms or parts. I don't believe the ferrari shall have any gearbox. only suspension, fake engine and HOG, maybe open hood/trunk/doors manually, just a usual lego car (besides Ultimate cars). my reference is 42096, it shall be identical with every aspect. or it shall be source of "single use" panels to make view better. I hope I am wrong on that assumption. I would love to see something "technically" interesting among those cars. If I am allowed to speculate, ferrari shall be "Ferrari 488 GT3", competitor of 42096 car. according to some sites I saw new 488 GT3 EVO 2020 is introduced in late 2019, so it is maybe time to introduce a lego ferrari for that car.

yes and no yes: less parts due to bricklink orders slowing down, also I lowered my spending on lego. no: before pandemic (start of this year) I got used to digital modeling. now I use %90 time on digital modeling, LXF and Stud.io. also since my office is very very close (next room to bed) now I have less worry about getting up early for the daily commute. for example I can stay long after midnight and get up for work in time. basically I have more free time actually. I am not spending entire time for lego of course.

some of them seems to be up and available in Bricks & Pieces. I checked rotor blade and it was out of stock but DBG panels seems to be available, likewise tapered orange 5x11 panel. there are no images available for osprey parts for now. maybe they shall be added later. set search gives no result but parts can be searched individually.

not worth posting here anymore.

hello everyone, maybe it is a stupid question but I could not find an answer online. neither search forums helped me about an idea. I am preparing instructions of a technic theme MOC with 2100 pieces total, using Stud.io. actually it is done/complete. problem/question is the file size I get with Stud.io. it is huge. I created the PDF using Stud.io in 330 pages/530 steps and the output of Stud.io PDF is around 200MB. I checked various PDFs from other modders and I see sizes around 20-50MB in very good image quality while Stud.io PDF quality is only good if 2x or higher is selected but file size is 200MB or higher even then. I looked into PNG compression tools briefly. I exported images from Stud.io, compressed the images myself and made a PDF, still file size is 100MB total. page count is same, image size is 1684x1190, kind of good quality I would say. am I missing sth about a compression? I tried another tool (lpub) and it generated 200mb file like Stud.io (but open 650 pages of PDF instead). I am not familiar with Lpub so I am not sure if I managed to do it proper way. what is the expected file size of PDF instructions if a fullsize A4 is used like Stud.io does? is 100MB file size accepted for a 330 page instruction? thanks

@Mylenium @SylvainLS @supertruper1988 thanks for answers. currently I am looking into (mass) image processing tools (pngquant and magick works quite fine for now) to convert the images to jpg. here is a sample page which is over 7MB with Studio 4x but I can compress it to 440 kb in jpg format. I use pdf24 to create PDFs and it generally does not add overhead to PDF size (PDF size is generally less than %2 more compared to total image size). not every page is like that, this is one of the biggest pages in size. most of the pages have multiple smaller steps. still if I have 300 pages total and average is 400kb file size then the total file would be over a 100MB. is that normal? that is my main question in the topic actually.

removed.

updated the first post with everything I have and currently working. I shall try to keep this up to date unless I get away from lego again. there are many small bits and pieces lying around but not worth mentioning.

here is a failed design of small scale front axle (partially virtual pivot steering). my intention was to make it driven, put suspension and also keep it 15stud width total with tire (from Mack anthem). it ended as below, not so good. usable if expectations are low. There is huge slack all over the axle and turning radius is terrible. the Z arms do not turn too much so steering is not so good. main slack comes from the 3L blue thin beam. I could not replace it with a better thing (the end has to go inside the wheel to make it 15stud, otherwise it is impossible with CV and diff) more photos in bricksafe. maybe someone can use the idea and make it better (or already done better)

hello guys, I made a raisable axle using a small linear actuator. it works fine and raises suspension by almost 1.5 stud and suspension still works which is nice. problem is the linear actuator's internal clutch. it pops up due to suspension press force if I manually press suspension for too long another angle principle is moving suspension's connection to axle's interior or outside to create a different angle on suspension which makes the wheel arms to raise or lower the wheel. suspension is not fixed, it moves and suspension shall work in low or high mode which is a requirement (I want it that way). now if I press suspension (half stud 6L beams or wheel) then the LBG #44809 (the shock absorber and frictionless pin is connected to it) shall move towards interior (middle of axle) which shall press the 3L red beam to forward. it is going to force the linear actuator to pop forward, and it does unfortunately. obvious answer would be to change direction of linear actuator, which is going to be ugly but possible. yet the same problem shall be there. this time pressing the suspension shall push the actuator's arm to inside. my questions? * I think I shall stick with this design (using small LA) because of compactness and it really does not pop up frequently. it rarely does when applying full force. I am thinking of changing direction (linear actuator shall be at opposite side) but shall this help? is actuator's internal clutch (or internal parts) have more force to prevent the arm to go backward or forward? * funny part is, I used linear actuator for fun and I trusted its internal clutch, holding power. it does not have much power it seems. It only needs to go forward 1.5stud at most and it is enough for suspension. alternate 1: worm gears with axles with stoppers? alternate 2: using linear actuator to create a more powerful but shorter movement and apply the power to the LBG pin through a beam (where in image LA is connected) what do you suggest? is small LA really that weak or did I break it during tests? cheers

we have cam already :) and it does not take too much space at all. in fact instead of the T beam I can put two technic cams in opposite direction and rotate it which can extend to 3L and retract to 2L. unfortunately the movement is little, half stud per wheel, not enough to extend the suspension. still a very good idea and can be applied for compact suspensions which I shall try for sure. not at this scale but maybe smaller wheel/tire options and different setups. thanks for reminding this. when you press the suspension it creates an additional force which is applied to LA. at that point LA pops up (due to the additional power applied to suspension). it only happens when you are testing suspension for example.I already said it in first post. LA pops up when I press suspension. it does not pop up when vehicle is stationary. I prefer the machinery to work in every position, not only in up/down situations. just personal preference. that is the challenge and fun. it is nice to watch it running slowly and smoothly and also working on every position. just like the wheel of the plane but not entirely functionality wise. your plane wheel must be on or off, just like a car door but a car height can be adjustable at various positions. when you put a steering wheel or HOG to your car, do you only turn it to max or do you want to steer half perhaps? same principle Do I have to use LA? not really but just for fun.I trusted its internal parts to provide me enough resistance to stabilize the suspension. I was wrong, that is why I created the topic. I looked at 8297 already. I am just testing compactness. I am not saying it is bad but I am testing different ideas. you can use #22961 to make it better. also for your previous example technic cams can be used since they provide 2.5stud beams.

read my posts above, it is already answered why I cannot remove half studs. in the plane there is no suspension so it is on its weight of plane. according to here the press force applied to shock absorber is around 1.2 kilo but not directly to LA so obviously less than 2.4kg yet still something, not just weight of car/plane/whatever. I also have a similar scale and at 2kg-ish the LA retracted forcefully just like in the post linked. it means pressing the suspension really applies 2kg force in my design. here the bushes gone and T beam is moved back to max possible. right position is fully retracted (secure position), left position is HALF retracted (most problem position). How do you plan to protect the LA to be popped up in half retracted position? you guys only think binary like on-off but I want to use at various positions, it is LA, it can stop at any position. forcing to use only low or high mode is very dull and also not fun at all. also depending on car weight maybe the weight itself shall force it pop up, assuming I put heavy stuff like battery etc. by the way my temporary solution is exactly like what you did in the plane. it works quite fine, it is even in pics (between suspensions and differential). I think I shall stick to that design, it is best in this scenario and it allows almost every position safely. cheers guys. thanks for help

@Aerolight thanks for the idea. I have not built in real but here is what I fear (direction also matters, I cannot move towards south in below image because dark brown axles shall hit each other before end): since LA shall pull the red T beam, it ?might? pull the axles as in blue arrow direction and connectors might pop. unfortunately the T beam does not stop at something I can backup behind. It moves around 1.4? stud, with lego it becomes unstable to back it up to prevent movement further (for example LA pulling connectors on the #44809 connection). not sure of course and it depends on the weight of car because car's weight shall push it back. even if the axles move a little then the suspension shall be clogged and disassembling might be required. in original design I might even add a gearbox to raise front or rear of car which would solve out of sync problem if LA pops up but solving left-right sync problem is messy, perhaps impossible. I hope I got your idea correctly. I feel it is not different from the original issue, we only empowered the push/pull power of LA due to different angle by lowering the link length. @MinusAndy does it ever become out of sync? for example when raising car or playing with suspension, like pressing? what if you mistakenly cause worm to skip a gear on big 24Z gear, would not all suspensions become out of sync? how do you prevent that? thanks for the answers.

thanks for the answer but I really did not get what you mean. here is the design with all other things removed. how do I turn the (red) links 90 degrees? I dont get what you mean. this is not steering, either both red links move towards inside or towards outside (pulling or pushing shock absorbers), at the same time, not one by one. it is meaningless then.

@Aerolight, 90 degree is dangerous. LA cannot push it (maybe?), the #44809 should be able to slide easily but in 90 degree it might be locked there. the small bushes on yellow 9L axle are there for this reason, to create an angle to allow small LA to push (pull the #44809 even at corner). also another factor: linear actuator, it is not 1 or 0, and it shall have between values. at between values the problem is still there, maybe less but consider low ride position (actuator expanded at almost max possible, not entirely), at this point it also causes pop because of the force. there shall be another problem. perhaps you can see the half bushes, yellow and LBG on yellow 9L axle. they prevent wheels to scratch over suspension arms (red 4x2) I cannot make it 90 degree unfortunately. 4x2 beam placement scratches wheels of 8070 (or 42096, smaller porsche set) without bushes which I think is for this scale. I shall test more though. @T Lego I have done 1:8 already, it works fine but with two small LA, one is definitely not enough but the movement is slow and long so out of sync should not be a problem at that scale (I can live with 1-2mm diff). principle is very different and it is not something like above (I raise entire arm plus suspension). I could not manage to pop in that yet but I also did not build the car. it is for later. above just came to my mind today for a smaller scale car/pickup :D temporarily I opted to go for my alternate #2 temporarily, at opposite direction. suspension falls when wheels are not on ground but it presses when it is on ground (and stops depending on LA position). I could not pop it up but the angle of LA arm scares me, it bends a little and I dont like it, I should find a better way. thanks for answers.
