  1. Some parts of the chassis had to be redisegned during IRL assembly, the sequential mechanism for the gearbox and it's housing required about 3 attempts. The roof above the cockpit is also the second version, it was a bigger challange than I thought.
  2. Two more images, now simply without the body. You can enlarge them until 4k resolution. Blue brick-built cylinder represents the air tank.
  3. I'm finally done with the renders of the chassis (Lipko ): Some structural parts and pins had to be removed, to get a clean result, but in 95% this is the chassis. ... and I mentioned an interview in the Stuttgart trip report topic, here you can read it: (some details in my answers weren't exactly these, but it's always the situation when you use foreign languages )
  4. My tubes are from a local store (called 'Bondex') in Budapest, Hungary, they sell many silicon products. They have no english website.
  5. I was waiting for a long time to a discussion, like this. Interesting theme, and we have as much opinions and point of view, as many of us are here. Basically, I can say, I agree with the first post of Erik, Lego MOCing should be done with Lego. I consider myself as purist, as possible to reach my goals with Lego designs. However, I have some exceptions, with justifications, why I use them: 1. Custom stickers: to get the small details on vehicles, as most of us do, sometimes a sticker is very important, eg. in a famous racing car 2. Custom strings and rubber bands: I mostly use them because of economical reasons, they can be replaced in 99% of my models with original Lego ones 3. Custom pneumatic tubes: until the inner and outer diameters, the hardness and color are the same (only minor shade differences can be observed), I don't even consider these non-Lego parts. When you really can't see the difference, then it can be considered as Lego. Of course, the reason why I use these tubes, is the price. I use only official lengths. 4. BuWizz: it's the only custom control system, I'd currently use (I'll buy soon), because there are absolutely no Lego alternatives for high performance. Even RC system doesn't came close when we see the given power/weight ratio. Increased fun factor is a great motivation to allow BuWIzz for your MOCs. Another reason to use the proper remote controlling range. All these in one unit. Some of my models will contain the BuWizz, but I'll try to solve even most of my high performance needs with 100% Lego. Let's say, I use it for some experiments. And, most important over all: cars with BuWizz can't be compared with full Lego cars in power, speed, performance. When someone use it, I think it's only fair to use when he/she indicates (eg. in the title of the video) that the car is powered by custom non-Lego unit. I'll do. I still don't (and won't) consider full PF cars 'lame' because of no BuWizz or SBrick. That's the level what you can reach with Lego in most of the cases. In their category (pure Lego) they can give as awesome performance, as eg. BuWizz in custom category. 5. Custom tyres: the last on my list, I use them to get acceptable traction on terrain with my trial trucks. It's a similar case to BuWizz, there is no Lego alternative to replace them in large scale (94,3 or higher), all of big Lego tyres have bad, hard plastic materials, except PP wheel (which I use often, but sometimes doesn't fits to a model, and very heavy). But, when I can use Lego tyres, I prefer them rather than 3rd party ones. It depends also on the actual rules of trial competitions: when custom tyres are allowed (by poll), then you will be in disadvantage, when you don't use them. Very rarely I use them for scale models (I mean not for TT), when none of the Lego tyres are even close to the needed form and size. These are all non-purists solutions I use. I don't consider taking apart Lego assembled pieces (like the springs in the mini 8865 MOC) and use their elements individually as a custom or even "gray area" solution. These are all made by TLC, can be found in sets, and if you are enough skilled, you can take them apart without damage. For example, I use a lot of Lego rim and tyre combination, some of them stresses the tyre, but at least it's full Lego. Beside this, I use the springs from disassembled shock absorbers, as parts individually. The reason for this are my building themes, I often build compact MOCs which requires small springs, and you can build sometimes much more interesting setups with only the metal spring part. To sum up, my sins are the custom tyres and the (planned) BuWizz use. I totally understand and respect non-purist builders, as long, as they indicate somewhere, the MOC contains custom or modded parts (of course, except of small things, eg. strings, rubber bands, etc). I respect also totally purist builders, who even don't use techniques which stresses some elements (likeTLC's official solutions to avoid). Basically, I really try to solve anything with 100% Lego, custom solutions are the last options for me. I totally agree with that statement that Lego is all about the achievement and challange with building pre-made, limited selection (both in form an color) of pieces. This is the essence, I think. If we became "lazy", and our first thought is to solve a problem (challenge?) in a MOC with custom 3D printed part, some from the essence of Lego designing/building will be lost. But I understand even people, who use glue, cut their Lego, to create the wanted form, model. That's also modelling, can be done professional too, but in traditional sense, definitely not Lego MOCing. IMHO.
  6. In this video: https://www.youtube.com/watch?v=H8QR7Sm9z5Y at 6:35, when he tries to order from a wanted list, you can see in the store price column the percentage of the price (below or over the average). Is this not available anymore? I couldn't find. This is (was?) the most useful function of Bricklink V2.
  7. Thanks! Yes, I have a pack uploaded, with parts list, instructions, etc. I used to organize this builds in private, I can send you these if you give me an email adress. (You can't receive or send PM in this site yet) If someone else is interesting about instructions, contact me in PM or here.
  8. Glad you like it. Among my plans is the much smaller version of Unimog 401, once it will be built. I developed a really narrow rim + tyre combination which works in smaller scale, and has the required look.
  9. Ok, thanks. I just asked the question about the categories above, because I don't want to give unnecessary work to moderators with moving my models from forum A to B, but in my case, I think it's hard to say in some models, which category they require. I build mainly 3 types, all of them are carefully calculated scale models: 1. Full technic MOCs with no or minimal studful parts --> Technic forum 2. Full technic chassis with full studful body, up to about 50% of technic parts in total --> as far as I can see, they go to Scale model forum 3. Mixture of technic and studful constructions, everywhere (like technic cabin and studful rear part in a truck): --> ?? where to put? (under studful I mean: plates, bricks, tiles)
  10. They don't. Voltage is about the same in RC and PF, but RC can deliver much higher current to the motors, instead of PF energy supplies (BB or Lipo) which can reach maximum 1,5 A. The RC unit doesn't drops the power, when it's under significant load. The only info, I couldn't find is the maximum current the RC unit can produce, but it's surely much more than PF/V2 receiver. It doesn't matter, the V2 receiver can give 1,5A per channel, when your battery supply can't.

  11. I have 4 from 8475 and 8366. I agree, cheapest way to get them is with sets, first of all in auctions, like ebay. If you want significant power with pure Lego, RC buggy motor (only with RC unit!) is essential. PF and V2 receiver can't get even close to the power of RC system because of the internal thermal protection, which regulates the current, and once it switches on, power drops to a very low level.
  12. I just discovered this new subforum, thanks to the moderators for it. Among my creations, I think this would perfectly fit here: And.. if I understood well, when a moc contains significant amount of technic parts or functionality, the builder decides where to put (technic or scale modelling forum), since there is no exact border line between them.
  13. Yes, Professor Porsche worked more non-Porsche projects, than Porsche. He died only a bit later (1951), when the first (Nr 1. 356) Porsche was produced in 1948. The Beetle is the most famous, but he designed a lot of german tanks, including Tiger 1. Among his works we find also Mercedes-Benz, S, SS, SSK types. (I often found his name in tanks, I have a non-technic project, too: http://www.eurobricks.com/forum/index.php?/forums/topic/100891-moc-mini-tanks-from-ww1-and-ww2/ ) Yes, I felt familiar with the interesting shots, it really makes the exhibition more impressive, and more informative. It was really well-organized. It wasn't planned, but when we were on the guided museum tour, only a really few other visitors were there. Because of this, I felt sometimes, the whole museum is only open for us. Thank you, at home, I'm planning to make a similar showcase plexi box for my model too, so I'll have two of them together. Or maybe from glass, to prevent scratches when cleaning. Thanks, I enjoyed writing it, and it's really great to see that so many people felt like they were there, too. This community is a great audience! thanks, and as you wish, here you can find all the high resolution photos: http://bricksafe.com/files/Tamas_Juhasz/lego-technic-porsche-contest-first-prize-trip-to-stuttgart-germany/316.JPG http://bricksafe.com/pages/Tamas_Juhasz/lego-technic-porsche-contest-first-prize-trip-to-stuttgart-germany And the same with image numbers at the end of the link: 318, 319, 320, 322, 324, 326, 328 - I have 8 photos from 550 spyder, it's a Carrera Panamericana racer. Fortunately it was showcased in museum, it's among my favourites, too. Maybe I'll build one in the future.
  14. Yes, I have tons of pics now. Some famous cars weren't there, like 911 RSR turbo '74, or Moby Dick, but they can't show every of their cars all the time, they told, the exhibition changes frequently, in october the transaxle models were in those places. Anyway, it was really interesting. I recommend to visit the museum for anyone, who has at least a little interest about Porsches. I'm glad you aren't disappointed because of the long waiting time, I was ready to post it a few days after when we arrived back, but I had to wait a lot of for the images from photographer, and the permissions, which of them are allowed tu publish. I got more than 100 photos, and only about 30 of them were allowed to upload --> and.. it's a great thing, because in most of the cases they send only a couple of photos for people, like me. Yes, the 911 cabrio was the "only" Porsche, we could drive, but it was perfect, and a 911 type (911 is in the pike of driveable cars pyramid). When we saw online the Porsche drive offers, we hoped we got a 911, and it became true, so we were really glad to try out such a legendary car. Big thumbs up for the Drive team. Of course, we didn't have to pay for fuel. The only more interesting car could be the purple 911 GT3 RS. That was route 1. from the roadbook, in direction to Öhringen, Castle Waldenburg (that you can see in my photos). Thank you! My goal was the same, to give something to you, I think that wouldn't be fair if I keep all of these for myself only. It seems, I reached my goal with the report. Thank you all for the kind comments. Thanks! I've never seen this technique in pictures. I didi with pleasure, thanks! Do you mean, only the chassis? I can make some renders about it, since I finished the LDD model, I'll put more infor to 962's topic soon. Well, I plan to make renders for all the main structural and technical systems. For sure, yes. (*he was the main engineer of 962) It has a story, too. The exact same real car was in the US, so it wasn't possible to make photos together. For us, only october was appropriate, but I don't mind, it could be worse, too. :) I talked a bit about Lego models with Mr. Landenberger, he told me, when they require such a Lego model car, they will ask me, but nothing exact was planned. The exhibition is all about real cars. You can see there even the main components, systems: .. or the shape changes in history of 911: Sounds great! What kind of Porsches do you drive/race?
  15. Hello everybody! After several discussion about photos, permissions, I have all the material about the trip to Stuttgart, which was part of the grand prize in the Rebrick "Build your dream Porsche" competition last year (summer). We started to organize the trip from 19th of august in email with TLC's online community specialts, and after a few weeks we fixed the date of the tour: 5-6th of October. To be honest, because of the so many awesome entries, I don't really believed that my entry will became first, so when the email arrived with the possibility to visit the Porsche Museum in Germany, my thoughts were only about this for a few hours, I was really exicted how it will be organized, about the details. I'd like to say a big thank you for both Lego's and Porsche's team, all of them did a really good job in organizing. We had everything in the right time, nothing had to be paid (except some meals), and every of my wishes were fulfilled, like making photos together with the original car, as you will see below. I know, I said, this report will come earlier, even I expected to have the photos (we had an official photographer) much earlier, but it's a longer process to be complete all the work on them, and the Porsche team had to discuss which ones are allowed to publish, etc. So, now I have everything important, and finally some time to write. Let's see what happened, in chronologichal order. (be patient while the pictures are loading, this topic contains nearly 150 of them, and this is the reduced selection ) Gallery with all the photos: http://bricksafe.com/pages/Tamas_Juhasz/lego-technic-porsche-contest-first-prize-trip-to-stuttgart-germany As they said, my model is allowed to take some photos with Porsche cars in the Museum, I packed it safely to avoid damage during the ~960 km of travel: The trip was 4 days long: 4,5,6,7th of october. 4th is day one. Since we were allowed to travel by car (fuel and additional cost were paid), this day was all about the journey to Stuttgart. Long motorway stages, all the usual, but it wasn't so boring. I was in Stuttgart before, me and my father visited the Mercedes-Benz Museum, and he was several times there in the last few decades. We did it the same way, two of us went to this trip. All in all, the route was familiar, and comfortable with car. We saw the table of Lego Land, Günzburg was close to the route. We arriwed about 20:00. This was our Hotel room, we had to choose from 3 five stars hotels, Meridian became the winner with it's great parking house. The room was beside of a big route, but the sealing in the windows were so good that in closed state the room is perfectly quiet. The main day with all the attractions, including Porsche Drive, Museum tour, and exclusive dinner at evening (in the Museum, Christophorus Restaurant). At morning, there was a huge traffic jam, but we arrived in time, and everything happaned, as planned, we met our contacts. The garage was a Museum inside of the Museum, too, with most of the cars from "Porsche Drive": This is the first you see when entering into the Museum: First program was the Porsche Drive, which was a surprise, in the contest description there was nothing about it. They give us a 2016 graphit grey Porsche 911 Carrera S Cabriolet, with about 420 HP, convertable top. Due to traffic situations, we couldn't reach it's top speed , but you can feel it's power even at around 200 km/h. (that stage had no limits in the german motorway) There were routes to choose, we went through the one with a beautiful castle, this contained nearly all the types of tarmac, curves, hills, slopes, so it was a pleasure to drive on. We were courious about the engine (but as both of us are automotive engineers we were prepared to see nearly nothing), but because of the top mechanism, you can see practically only the fans. Interesting that you can see the rear wheels outer side from your seat: This is the maximum, you can see from the engine (from above, of course): Back to Museum, around 13:30. In Zuffenhausen (part of Stuttgart, where the company is located) every second car is a Porsche, you can see many of them (not a surprise): This was added with the car: Fees and terms, if somebody is interested: I was very happy to take apart in a so exclusive tour, Mr. Dieter Landenberger, the director of the Museum and Porsche Historical Archives was our guide, he talked about many interesting facts about lot of extraordinary types, I have to mention the 909 Bergspyder, which was as light as possible (384 kg!!). The following ~ 20 photos were taken by the photographer, I'd like to say a big thank you for him (Pascal Malamas). The special exhibition was about the transaxle era, so we found a 944 Turbo Cup with the same color scheme, as my 962C model: And now, my favorite photo so far, in the Museum's workshop. From left to right: one of the original mechanics of Porsche 962C, Mr. Landenberger, my Father, me, our contact form TLC, and two colleagues from brand entertainment of Porsche. I really like this photos, as it contains every important people and things. Some more from Workshop: Then we want on foot a bit further, in a centre, where the (nearly) 1:1 scale Porsche 911 GT3 RS is located. From now, I had in hand my model, so we could took photos with it everwhere: Back to Museum again, they did an interview with me (even I waiting infos, news about it), and during that the rest of the team made some more photos together with the model and original cars: Finally, the original and my version together: (ok, it's a 956, but that was the closest to 962C) : ) Dinner at the evening, with some exclusive food. Since my model was with me, it landed on the table. Some interest appeared from other guests, they saw it couriously: Through the glass wand, you can see the Museum, some real cars: SIght from the top of the Museum was really nice, especially at evening: At the third day, we went back to the Museum, to see everthing in detail, and to take some good photos. I made more than 600 of them, to get material for my future Porsche plans, the Museum is very good for it. They even have blueprints for some types in tablets in front of them. Some of the more interesting photos: This Beetle looked fantastic, it was really in top condition, this photo was a must have: Since my father's hobby is collecting automodels, we brought there a 1:43 model about Porsche 356 Nr.1 roadster: (Nr1 typ is one of my favourites, that was my second plan for the Porsche competition, awesome car in every meaning) I tried to take photos about the types, which were in the Lego contest, like 919, 714, 904, tractor, and 804: Interesting: I found material about my model many times, first here: At the speed of 321,4 km/h the 956 shouldn't fall down from the roof: I like this exhaust pipe: Long and racing version from the 928, both are very rare: Some of the prizes, Porsche had won during the times, in the background the flag was in movie "Le Mans" (Steve McQueen) GT1 street version: We saw large scale models, too: The magic wall, it hides everything, except there, where you are in front of it: 918 Hybrid: 718: It has a really nice shop, with lot of model cars, we bought some, too (see below): Finally a Lego thing: Here was the red-yellow racer, too: The GT3RS 42056 set wasn't available in the store, but we found the real in the garage, aming "driveable" cars: In day 3, we also visited the Factory, we saw the making of nearly all types of current Porsches, but I can't provide any photos, since - of course - there wasn't allowed to take them. The Museum isn't the only option for car lovers, you can see nearly every type of Porsches in the streets around Stuttgart, too. if you are lucky enough: At day 4 we travelled back to Hungary, during we saw Legoland a bit (really just a bit, from the car ): From the Museum's shop: Small card collection of famous Porsches: At the middle of day 2, we received a kind gift from entertaining team, a nice book about 2015's motorsport happenings, with Le mans in focus. Big thanks to Porsche for it! Do you know, what it is?: Back to Lego, there are some pages in this book: At 21.12.2016 we received a big misterious box, from Porsche. I couldn't even imagine, what's inside, since all of my prizes arrived, the certificate too, many months earlier. I thought, it's something about the Museum trip, because it arrived after that. But 2 months later. We opened the box couriously, and it's content revealed (everything were packed with lot of care): It's a "simple" picture for hanging to wall, but made partly from metal sheets, really inetersting, and sturdy. Can you tell me, exactly which technique is this?: It's something that fits for a car company. I hope you enjoyed reading this report, I tried my best in text and photos, it's really hard to select only about 100 from all of those, I took, and got. Any questions, comments are appreciated, as always. The interview should be publicized soon, I'll link here, as it appears, or when I'm informed about it. It seems to be, I'll have more time for Lego, forums from now, this report is some kind of being back.
