WOW, this baby is huge, very cool. And thanx for the instructions !!!

I'd vote for the chicken too, it's the most original IMO.

I've recently uses some (10-year) old valves in two models, but they didn't give any real problems. I've noticed that (bigger) pneumatic systems aren't 100% air-proof, but no air-leaking-noise or equivelent.

When making an MLCad file I automaticly think about how to assebmle it and insert steps immediately, thats just the way I work. But a MLCad-file for a model this size would propably have between 25 & 50 errors to exactly match the original and to privide 100 % correct instructions. And it's not that I don't like making MLCad-files (in fact, I like it quite a lot), it's the finding of the errors and making the final instruction-pages that's less fun and time-consuming, but neccesary. So if you (Blakbird) are willing to do the last part, then I'll make an MLCad-file (including steps). In fact, I've already asked Sheepo for permission and assistence. But as I mentioned before, it will take some time before it' would be finished. So to be continued.....

Good to know I'm not the only one who spends hours looking at a Technic model . I may not have a collections as big as Blakbird (I own "only" about 20+ Technic sets) but I will propably admire a good Technic model about as much. Ok back to the subject... I've actually given it some serious thoughts to take on this project (first it seemed impossible). Another problem became clear quickly: time. Let me elaborate: I'm a builder, meaning I take most joy out of making things. And making my own models, my own technical systems, admiring the working functions I've created is what I like best of all. That doesn't mean I don't like other models (this Veyron is still enourmously impressive), they will just never have the same value to me as my own babies. And I don't have the means to keep every model intact forever. That's where MLCad comes in: it allows me to document my own creations, so I can make them again or look up how I made stuff. As an extra, it allows to easily share models with other people (& make very nice renders). The primary reason for asking Sheepo to LDraw his gearbox was so I would be able to include it in one of my models. The second reason was to enable Sheepo to share his creation. And making such a model in MLCad doens't take much time for me (it was done in less than a day). Digitalizing the complete Veyron one the other hand is an extremely time-consuming project for a number of reasons: 1. It's a big car 2. I didn't create the model, so I have to analyze it first, 3. MLCad becomes quite slow with models over a thousand parts, the more parts you put in, the slower it gets. 4. Debugging the model takes at least as much time as making it. I estemate such a project will take about a couple of weeks to a month, and all has to be done in my spare time, time I can't spend building my own stuff. As mentioned before, I'm working on a new supercar of my own, and I would really really really really really really like to finish this first. So as you might understand Blakbird, I would like to give it some more thought, before actually asking Sheepo's permission and help. I would still be honoured to do it, but I must be realistic and ask myself how much of my building time I want to spend on somebody else model, I hope you understand.

TLG has some tutorials themselves: http://www.lego.com/eng/create/technicdesi...ool/courses.asp This website has some usefull info: http://www.owlnet.rice.edu/~elec201/Book/legos.html And some nice tutorials for LDraw & MLCad can be found here: http://www.holly-wood.it/index-en.html

No, I won't be modifying my "Wasp"-supercar (it's been disassembled more than a year ago....). I am making a completely new car with will feature this gearbox.

Very nice buggy & thank you very much for making the instructions, it's being highly appreciated.

Ok, I guess I will move to Spain then And it doesn't hurt to ask, you're right. BTW, why is it an important project if I may ask ?

As noticed earlier by dluders, I've created a new gearbox. (maybe an admin wants to join these 2 topics to keep the forum tidy). For some time I wanted to make my own remote-controlled reliable gearbox with more than 2 speeds. I've seen some nice designs, like Sariel's aeroshift and Sheepo's 7+R gearbox, for which I've had the honour to make building-instructions. See mine in action: name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src=" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="480" height="385"></embed></object>"> name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src=" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="480" height="385"></embed></object>" type="application/x-shockwave-flash" wmode="transparent" width="425" height="350">There were a number of important aspect: * Reliable drivetrain * Preferably 4-speeds * Being able to switch gears with a single motor * No pneumatics Like in Sariel's design, the transmissions consists of identical modules, where each module has 1 driving-ring and adds 1 gear. All the gear-ratios are identical: 5/3 from 1st to second, 5/3 from 2nd to 3rd and 5/3 from 3rd to 4th. The total amount of gear-reduction is about 4,63. By using the 24-8-tooth gear combinations (instead of 12-20), ratio's of 3/1 can be achieved. For effeciency-reasons, the gearbox only reduces speed, the highest gear is actually neutral (same speed coming out as is coming in). Also for the efficiency, the module(s) with gear-reduction are located nearest to the input. This way the dead gears have less effect. The switching systems was inspired by Sheepo's gearbox, but I wanted to use the ridged axle-joiners insted of the smooth ones Sheepo used. This way the driving-rings would stay in place better, contributing to a more reliable drivetrain. This gearbox will be used in my new supercar, with which some succesful driving tests have been done. I plan to expand the desing with some kind of stepped motor to improve the swithing-system, but for now it works quite nicely. I've made complete step-by-step building instructions so you can include this gearbox in your own designs. You can download them in my brickshelf-folder. All comments & suggestions are welcome.

They look like model-team, but are packed with quite a few advanced technic-functions, so for me they are technic

Man, you are fast !! Even before I've posted it here, you already have !! I will post it anyway, including all the links, a video and more pictures.

Thanks Blakbird. I would be honoured to make instructions for the complete car, but there are some problems. Making correct instructions requires me to have the car personally at my disposal. Since Sheepo lives in Spain and I live in The Netherlands, it's not likely to happen. The instructions for the gearbox were made based on Sheepo's instructional pictures he put on his MOC-page. First I built it, then I made the MLCad-file. Besides that, I would need Sheepo's permission of course (although I don't think that will be the biggest problem). But I've created my own which will be published here soon, including instructions.This gearbox will be used in my new supercar that I'm working on now. The first tests of the 80% complete chassis look promising. It the model turns out good, I might make an MLCad file for it.

That's one of the reasons I made it (although it took quite some time). I like to make things that haven't been done before. I promiss I won't put big pictures in my posts again.

Done the survey and added EuroBricks & TechnicBricks as frequently visited websites. And the question if TLG should focus more on adults gives good hope in TLG releasing more complex sets 8-)

I agree that Sheepo's Veyron is the nicest. And his gearbox is so cool that I made an MLCAD version (with Sheepo's permission). You can find it and the buiding instruction-pictures in Sheepo's Brickshelf folder.

Thanx for this, Siegfried. It put a big smile on my face. Lego Technic can definately be funny too !!

Well, if TLG would ever release such a supercar-set, I would definately buyt it !! I agree with you that a RC Technic Supercar would be a fantastic edition to the Technic-line, either designed by an AFOL of by TLG.

The initial plan was to make the front loader completely electric with LA's. But I wanted to build the mechanism to keep the bucket in the same position while moving the loader up and down and doing this with LA's was almost impossible. It would have resulted in lots of gears on the outside, which I think is ugly. Pneumatics were also used for the backhoe, because there wasn't any place for motors (I tried). The images in my topic-post were reduced to 800x600. I hope this is enough. If not, just let me know and I'll shrink them even more.

First of all, I'm honoured by the fact that some people consider my model(s) to be of the same or better quality that the designs of TLG. But this rises the question: how can you determine the quality of a construction ? Clearly there are a number of (commercial) aspects that TLG have to take into acount, whereas I don't have any commercial restrictions. My Little Devil has aprox. 1800 parts, about the same as the Crane truck, meaning it would have to cost about the same, but the latter is almost twice as big and has more fuctionality. The question is what the average consumer would buy for the same money: a Little Devil or a Huge Crane Truck ? The Little devil can be stripped of the lights and some details to make it cheaper, but the remote controlled driving & steering are essential. Adding a motor to a finished model would require taking most of the car apart. And as posted earlier, the TLG-designer are propably capable of designing something very similar, if not even better. We just don't see everything they make. As for the amount of time going into a design: The Little Devil took just over a week to make and another 2 weeks to make the instructions (in my free time). The main car was constructed in a single (whole) day, all the details took about a week to complete. TLG would propably take one or more months to develop it, several Little Devils would be made from which the best would be chosen. (This makes me wonder why the Crane Truck still had some design flaws, which were corrected later by an AFOL...) Having no commercial restriction makes it easier to make an impressive model, cause your only limit is your own collection and wallet (for ordering on Bricklink 8-) ). This makes it easy to add more lights, motors, more details, make your own remote-controllers (like my JCB 4CX Backhoe Loader), but does this make a model better ? For TLG this is hard-core business, they have to live from making Lego-models. For me, it's just a hobby. I'm a creative person and I like creating things that weren't there before and share them. For Lego-designs that means that I try to design something that TLG doensn't and whenever possible, to share it with the Lego-community.

Building a functional Backhoe isn't easy indeed. This MOC was constructed very compact to be able to include all the functions (6 electric & 5 pneumatic functions in total) I saw your JCB 3CX on brichshelf earlier and it inspired my MOC. And the small steering-lock isn't a problem. The original 4CX will also have a small steering-lock due to the big wheels. But this is compensated with the 4-wheel steering. Thanx for the compliments, Allanp. Yes, I'm aware of some backhoes having a telescopic boom. I even considered making it, but the model was already very complex as it is. And sorry for the pictures that were too big. I will make them smaller.

The creations of Igmar Spijkhoven are absolutely gorgeous. Ming Thein also makes stunning models. And people have to see Jeroen van Hove's creations as well.

There are a lot of technic excavator MOC's out there (I've made one myself as well) but this is the prettiest of them all. Looking really smooth with all those tiles and shapes.

Hey there, Here is my latest creation: a fully remote controlled Backhoe loader based on the JCB 4CX, which is a Backhoe loader with 4 equal-sized wheels & 4-wheel-steering. name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src=" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="480" height="385"></embed></object>"> name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src=" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="480" height="385"></embed></object>" type="application/x-shockwave-flash" wmode="transparent" width="425" height="350">This model features a blend of Pneumatic & power-functions. It has: * 4-wheel drive * 4-wheel steering * V6 engine * Lights * Outriggers * Fully functional front-loader * Fully funtional backhoe (including sideways-movement) * Everything (even the lights) are remote controlled by a seperate remote controller. For years, the 8455 was the standard in Lego Technic Backhoe loaders, but with the presence of the Power-functions system, I know it could be improved. So a specific Backhoe was chosen, in this case the JCB 4CX which was to be modelled. This is a Backhoe with 4 equal-sized wheels, which made the choice for the wheels a lot easier. Now the 8297 wheels could be used. And of course the 4-wheel-drive & 4-sheel steering had to be implemented. For every function both pneumatic & electric systems were considered. Power functions have the advantage to be very controllable, but generally need quite some space and reliable drivetrains. Pneumatics are easier to construct and quite powerful, but are harder to controll. While examining the 4CX, I noticed that its complete backhoe could move sideways. This was quie a challenge to recreate. A kind of rails was constructed to guide the moving backhoe. The M-motor which was used for the sideways-motion was placed inside the main body, and the M-motor for rotating the backhoe was placed in the first section of the backhoe. The remote controller houses a compressor, air-pressure-regulator and all the switches for all the functions: You can find my brickshelf-folder here. If you want mail me for questions about my models, you can find me at jurgenstechniccorner@hotmail.com Feel free to comment.

I regularly wish for a non-existing parts while building MOC's. But not having a specific part makes you more creative, having to solve the problem with other parts.
