April 5, 201311 yr Just thought I'd throw my humble MOC into the mix! Or more seriously: Edited April 5, 201311 yr by grum64
April 5, 201311 yr Author Hmm, the look of this combine 8274 is indeed realsitic but the functions aren't or - to be precise - i miss a lot of function, so for example the complete internal further processing of the corn and grain ... maybe you will laughing but IMHO the combine from the old ideas book 8888 is the most real one - take a look at the picture: it has all functions the 8264 has too (apart from the lifting of the cutting unit) but it has some important in addition: - a transport of the cutted cornstalkto the internal processing - made with chain treads (see left side) - a mechanism to separate the corn (see yellow parts, A and B - these are driven by gears!) Of course the look of this very old model is quite blocky and not as realistic as 8274 but concerning to the realistic working functions i prefer this red one above...
April 5, 201311 yr Just thought I'd throw my humble MOC into the mix! In my previous job I fixed and hacked some similar machines. What can it do? Does it have a full standing-up function? It would be quite awesome if it knew all the functions the real ones do. I thought about building MOCs like that, but I guess not many would admire them, and I'm only doin it for the fame of course
April 5, 201311 yr Actually, many truck cranes do use linear hydraulic actuators to slew the crane tho they are often mounted differently. It's very hard to pick between your top 3. Gonna have to look at all the realistic fuctions and other details, however minor they may seem, and compare. = life like, = not life like. 8868: 4 wheel drive Fast spinning v6 belt driven engine Steering Fluid under pressure actuated (FUPA from now on!) Crane slewing . Fupa Arm raising/lowering Fupa Arm bending Fupa Claw opening/closing Straight sections of hose are rigid, bent senctions are flexible Fluid pressure built up by compressor (even sounds ) Rigid beam chassis No outriggers 8110: 4 wheel drive Slow spinning inline 4 shaft driven engine Steering Electric crane slewing Fupa arm raising/lowering Fupa arm bending Fupa claw opening/closing Flex hose throughout Fluid pressure built up via compressor (although sounds due to slow speed) Suspention Flexible chassis Portal hubs Working PTOs and PPTOs Non Fupa outriggers 8455: 2 wheel drive Fast spinning 3 cylinder shaft driven engine Steering Fupa front bucket raise/lower Fupa front bucket tilt Fupa back hoe raise/lower Fupa back hoe bend Fupa back hoe bucket Fupa back hoe swivel Fupa out riggers Flexible hose throughout Flexible chassis Fluid pressure built up by hand pump and no compressor sound So, to compare 8868 gets 11 out of 14 thumbs (79%), 8110 gets 11 out of 17 thumbs (65%) and 8455 gets 11 out of 16 thumbs (69%), meaning in this ever so slightly hamfisted scoring system at least, 8868 comes first, 8455 comes second and 8110 comes third. Those may seem like low percentages for these most outstanding sets, but this a difficult test which shows that even the best can be made better. Just to show how difficult, lets do another one for fun 8043 6 non Fupa functions (in real life all of these are Fupa, and yes, air is a fluid!) = :thumbdown: :thumbdown: :thumbdown: and another for being RC. That's 0 out of 7 thumbs, 0% . So in terms of realism, the order of the top 3 is identical to yours. However, in fairness to 8110 it's percentage is lower because it has more functions to have to replicate, it's more ambitious. It was marked down for having electric slewing but at least it has mechanised slewing. For it's extra ambitiousness and attempts at recreating a realistic drive train as well as it's other functions (something 8868 and 8455 haven't really tried to do as much) it still ranks amongst my all time favorites, and like most top 3s or top 10s of movies, songs, technic sets and whatever, my personal picks for top spot is always changing, but 8868, 8455 and 8110 are always in the top 5. BTW, I don't think it's coincidence that Fupa kinda sounds like F*****g Supa! Edited April 5, 201311 yr by allanp

I thought about building MOCs like that, but I guess not many would admire them, and I'm only doin it for the fame of course It's has PF & the features of the Meyra Optimus 2 I use. More here: http://www.eurobricks.com/forum/index.php?showtopic=73378&hl= Stopped building it for a while to concentrate on the Crawler and a recently arrived (prestine!) Williams F1 that started 'calling' to me. As for progress on that, page 32 is on the horizon. Edited April 5, 201311 yr by grum64
April 5, 201311 yr Author It's very hard to pick between your top 3. Gonna have to look at all the realistic fuctions and other details, however minor they may seem, and compare. = life like, = not life like. 8868: Fast spinning v6 belt driven engine Straight sections of hose are rigid, bent senctions are flexible nice exercise, allanp! sometimes i think you are too severe (e.g. V6 = , because for the sake to show childrens how the real things are working it doesn't matter if there is a V6 or a V8 engine, the important thing is, that there is a fake engine at all - BTW: many modern trucks have big V6 engines) on the other side this severness is absolutely correct and necessary: this belt driven engine of the 8868 is really a clumsy solution... And you have pointed out really important aspects concerning realism: these "Straight sections of hose are rigid, bent senctions are flexible" are very conducive to the very realistic impression of the Air Claw 8868, you are right - i have simply overseen this in my chain of reasoning... What i had in mind when opening this topic was the realism in the main focus of a model, so things like spinning speed of pistons or number of cylinders of the engine doesn't matter - suspension is a great example for this: with cars this feature is in the main focus of the type of model so it should been as realistic as possible, whereas suspension with a truck model is not in the main focus - hmm, let me rethink this: on the other side suspension for a MOG is an important feature - well, so i would say: suspension on a model like a Unimog should work realistic but for a truck like the 8868 the lack of a suspension is completely negligible so the for the MOG-suspension is right but i would remove the for the missing suspension of the 8868... Hmm, sounds complicated... maybe we should not elaborate this as rocket sience 8043 6 non Fupa functions (in real life all of these are Fupa, and yes, air is a fluid!) = :thumbdown: :thumbdown: :thumbdown: and another for being RC. That's 0 out of 7 thumbs, 0% . :laugh: seems you really dislike the 8043...
April 5, 201311 yr BTW: many modern trucks have big V6 engines) Big trucks have inline 6 engines. I think V6 is very rare. seems you really dislike the 8043 I think this is fascinating topic because it separates "realism" from "goodness". 8043 is a really good model! It has the functions of a real excavator and is fun to use. However, the way those functions work is not at all like they really work, so it does not score high on realism. Even the JS220 by Jennifer Clark is not totally realistic. All the pneumatic functions and the compressor (even the controller) are like real life, however the slew and drive are electric and they would be hydraulic on the real thing. I don't think any builder has managed FUPA rotary drive on a MOC yet. An LEGO pneumatic engine doesn't count even if it uses fluid because it is simulating an internal combustion engine, not a rotary actuator. However, an LPE is an excellent example of a VERY realistic model.
April 5, 201311 yr Very good point about the suspention not being the main focus. Hmmmm, I think I may have to re-evaluate my data for this rocket science! EDIT: On second thought, hmmmmm, 8868 looks like an off roader with those tyres, suspention would be a pretty important thing, but obviously not that practicle in such a model of 1992, for that i'll remove the suspention score from 8868 Edited April 5, 201311 yr by allanp
April 5, 201311 yr Author Big trucks have inline 6 engines. I think V6 is very rare. yes you are right - i had only the number of cylinders in mind but not the mounting form... I think this is fascinating topic because it separates "realism" from "goodness". 8043 is a really good model! It has the functions of a real excavator and is fun to use. However, the way those functions work is not at all like they really work, so it does not score high on realism. 100% agree... therefore i said that my ranking would be different for the question "what is the best model?" because for the term "best" you have to combine several criterias... But because the technic line has been started with the slogan "...as in reality" (at least in germany) i was interested to see how well this slogan was implemented... Even the JS220 by Jennifer Clark is not totally realistic. also agree - but i would say: it is as realistic as it gets with current lego parts - as you said, no builder has managed FUPA rotary drive until now...
April 5, 201311 yr Author see posting #29: Fluid under pressure actuated (FUPA from now on!) - means here with lego: airpressure driven rotary-modul
April 5, 201311 yr in aerodinamics you are right, but in an pneumatic actuator it is completely out of context. do you have learned on an university to say simple things in complex words? and by the way, kumbbl what is that? fluid under pressure actuated rotation?
April 5, 201311 yr in aerodinamics you are right, but in an pneumatic actuator it is completely out of context. do you have learned on an university to say simple things in complex words? I was the one who started using the word fluid here. I guess you are right that maybe because I have a university degree in fluid mechanics I use the word differently than other people (gasses and liquids are both fluids). The reason I used the word "fluid" is that all the laws and principles and formulas which apply to hydraulics apply also to pneumatics. The only difference is what number you use for compressibility. So in this way LEGO pneumatics are very realistic in that all "fluids under pressure" make actuators work in a similar way, while mechanical actuators like the PF linear actuators are very different. By using the word "fluid" I can say that both the real thing and the LEGO parts work similarly.
April 5, 201311 yr Author Yeah, well, you, um, spelt "modul" wrong (not that my shpelling is any better!) yeah, you are right - but explain us please, which component of a car the "suspention" is, which you mentioned very often - what exactly does a "suspention"? kumbbl what is that? fluid under pressure actuated rotation? nifty... how does the rotation work?

April 5, 201311 yr Most realistic? I think the motorcycles are just that. 2 cilinder engine, direct steering and chain drive.
April 5, 201311 yr Most realistic? I think the motorcycles are just that. 2 cilinder engine, direct steering and chain drive. what about a under seat compartment or movable seats
April 6, 201311 yr Name one lego set that has an compartment anywhere inside, it doesn't even have to be under the seat... As for the moveable seats: there is 1 set, the first (or was it the second?) supercar, but that didn't have a roof or windscreen, so it wasn't realistic at all. So the motorcycles win :D
April 6, 201311 yr Author As for the moveable seats: there is 1 set, the first (or was it the second?) supercar, but that didn't have a roof or windscreen, so it wasn't realistic at all. the 8865 supercar has out of the box moveable seats and also a "body" with windscreen... the 8880 can be moded to get moveable seats - see here: http://www.eurobricks.com/forum/index.php?showtopic=79397
April 6, 201311 yr Author please look http://www.brickshel...kopfgreifer.lxf Hmm, either i'm blind or i have missed something... this is all i see in LDD: I do not see any pneumatic hoses, cylinders etc.. so how should i see how your air powered rotary-module works? But to be honest: i'm a newbie with LDD, just installed 30 min before...
