Here one more possible solution. Very simple and without unwanted motion

I didn't know this rule about a single or multiple studs inside the technic holes. Thanks for share it with us ;)

I think the same as you, I think Crowkillers and me are the main guily behind the lack of some red pieces And even worse, the problem will be bigger and bigger every new year...

I have never said that the white hoses be offensive!! I only told that they are the worse of all colors I have bought. Actually it is not bad color!! I never talk about my next model, but probably it will not be DBG ;) I am not sure if I can put the link here, but if it is not correctly, plese delete it: http://blokbricks.com/contents/en-us/d2.html

So, You are the guilty of the shortage red soft axles in BL!!! Just joking :wink:

After some days waiting, yesterday I received all these hoses: In all of them the feel is almost exactly than the Lego pneumatic hoses I will check one by one: Red Very close color. The silicone is slightly transparent, so if there are many light in the room you can see a light tone difference. Compared with the red soft axles. Like the solid parts very close to the official parts. Yellow Same case as the red. It is very close to the Lego color. The silicone is slightly transparent, so if there are many light in the room you can see a light tone difference. White This is the worse hose color. It is not too bad, but the hose color is clearly lighter than the Lego white Closer Light Bluish Gray (LBG) I bougth it thinking that this color will be the same as the Lego pneumatic tube LBG, but it is not exactly the same It is really well done and more accurate than the Lego official Here a comparison with official Lego hose from 8110 set (top) and this aftermarket hose(bottom). The Lego official is slightly lighter Dark Bluish Gray (DBG) This is my favourite color of all these hoses. For me it is just perfect. Exactly the same color and solid(not slightly transparent like red or yellow) I hope this can be usefull for all of you.

The pneumatuc tube can be connected using for example a short hose rigid, a bar, a pin with stud and bar, a T pneunatic connector etc...

Thanks blastem. Meatman, that hose rigid is even more rare than soft axles... in almost all sizes. Also the diameter is smaller, so the cars will look strange.

That is part is called Hose Flexible Ribbed with 8mm ends. http://www.bricklink.com/catalogItem.asp?P=57539 The problem is that the only available lengh is 19L...

Hi people. I want to talk about a big problem when you create a technic MOC: the soft axles. They are very usefull to create soft curves, corners and transitions in technic models, specially in the bodywork, but as probably all of you know, the soft axles have a big availability problem. In BL the prices are completely crazy(specially in red), and quantity available are not enough (who can not remmenber the 19L in black...or the 14L in red) When I designed the GT500 in 2012(yes 2012, there is a long story behind this car...), the cost of the soft axles were very low, the 11L in red cost was around 0.30€ each, and high availability. Now if you want more than 2 you should pay more than 3€ each, and you can't buy more 10 in any store, that is completly crazy!!! In my new car(it is finished, I will show it comming soon) I have used many red soft axles. I have many red parts in home from some years ago, so I have not had to buy red parts to build it. My original intention was make instructions, just like the Mustang, but now I am not sure if it will be a good idea: if you use ALL red soft axles available now in bricklink probably only 4 or 5 copies will can be built. I want to continue building my cars with detailed bodyworks(I think most of you think the same), and without soft axles that is almost imposible. I am very purist with non-Lego parts, but I think this can be a good moment to find some alternatives out of Lego oficial part to keep the building level. The pneumatic tubes can be a solution: they are flexible and have the same diameter as the soft axle. But they are only available in black, light gray and blue, nothing about red, yellow, green, white... I know the rigidity, strenght, and touch feel are not the same, but if any of you know a better solution please leff me know. I have found a store where you can buy pneumatic tube 100% Lego compatible in many colors: black, blue, brown, dark blue, dark gray, green, light gray, red, tan, teal, trans clear, white and yellow. And with very good price: you can build the complete GT500 in red with less price than only one 14L red soft axle purchased in bricklink. And now the question: What do you think about this? The alternative pneumatic tube can be a solution? Even in a desperate moment the non-Lego parts are not allowed? I want to know your opinion. Thanks Sheepo

I didn't want to show it before make the video, but here you have. Obviously it is nothing really new, just a more compact version of the tipical double-worm Lego torsen diff.

I have tested it with 2 L motors with gear reduction, and it works really well. The main principle is the same as zblj with 2 worm gears and some 8t, but I have been able to place it in less space.

These are already available. The 3rd gen servo switched gearbox is part of the Mustang GT500 for which instructions are available. Thats is correct, actually you can built any gearbox using the "logic" of the Mustang ones. You can download instructions step by step in PDF (pdf by legolijntje) for that gearbox in my website. ;)

I designed a torsen diff some months ago. It is smaller than this. I will publish it soon, I want to make a complete video to show it, because a few people know what is a torsen diff.

Today is the third anniversary of my website!! And for celebrate it I will show you many information about all my sequential gearboxes until today. With my latest cars I introduced a new sequential gearbox type, and to avoid problems with how to call this new one, I decide add a new way to call all of them. Since now the new versions of the sequential gearboxes will be called with ordinal numbers. In this ordinal numbers don't enter other gearboxes types like: dual clutch, planetary or CVT, just normal sequential gearboxes. 1st Generation This was my first sequential gearbox(I think this was the fisrt Lego sequential gearbox with more than 3 speeds, but I am not sure), I designed it in 2009 to be used in my Bugatti Veyron. The version used in my Veyron is a 7+R speeds. with a little modifitacions you can get a 4 speeds or a 5+R speeds versions. The main feature that distinguishes this generation is that it has a speed selector in linear motion, and the distance between speeds are 2 studs. Correct speeds change ratio: ~70% In Octuber 2010 I designed a second version with auto-clutch. It worked fine, but I decide not publish it beceause it was too big to be used in any car. 2nd Generation Before to finish the Veyron, I started to develope a new car(the Porsche), and even before I know what car I will build, I wanted to use again a sequential gearbox, but the Veyron's gearbox wasn't an option because it was too big. In the search of a new smaller gearbox I developed many differents prototypes. And this was one of them. Finally I decided to use a dual-clutch gearbox to be more accurate to the real Porsche. The main feature that distinguishes this generation is that it has a speed selector in linear motion, and the distance between speeds is only 1 stud. I have used this gearbox in 3 of my big MOCs until today, all of them with differents speeds configurations and add-ons. Type 1 - 2 switches(4 speeeds), without auto-stop, without clutch (Mini Cooper) Correct speeds change ratio: ~90% Here the Mini's gearbox. It was the first You can download the step by step instructions in my website. Type 2 - 3 switches(5+R speeds), with auto-stop, with auto-clutch (Land-Rover Defender 110) Correct speeds change ratio: ~80-85% Here the Lad-Rover drivetrain. This drivetrain also includes a range gearbox and a 2WD/4WD selector, but the sequential gearbox is a normal 2nd Gen gearbox. Type 3 - 5 switches(9+R speeds), with auto-stop, with auto-clutch (Peterbilt 379) Correct speeds change ratio: ~80-85% Here you can see the whole Peterbilt drivetrain. You can se the main gearbox, the drive motors, the range gearbox and the pneumatic module(compresor, compresor control and brakes control). In total 5 PF XL motors and 3 M. 3rd Generation The history of this gearbox is very strange. Like the 2nd Gen, this gearbox was initialy developed as a alternative gearbox for the Porsche, but in this case I couldn't make a good system to generetare the auto-stop mechanism, so I leave it in a box of a while... The main feature that distinguishes this generation is that it has a speed selector in circular motion. To reduce the size of the few speeds versions I created two types: one for 2 swtiches and another for 3 and 4 switches. Type 1 - 2 switches only This type change one speed for each 90º of the selector switch movement. Correct speeds change ratio: >95% I will publish some information about it comming soon. Type 2 - 3 & 4 switches This type change one speed for each 45º of the selector switch movement. This gearbox is specialy recomended for 4 switches, because with only 3 switches the saved space compared to the 2nd Gen is not significant, maybe around 5-10%. But with 4 switches the saved space is more than 20% Version 1 (V1) - Caterham Seven (with auto-stop, with clutch) Correct speeds change ratio: ~85-90% This new gearbox is more reliavable than the 2nd generation, but it still have a little problem, and I need to fix it before publish nothing more about it: it can't support high torque. I could avoid this problem in the Caterham adding an external torque converter, but this is not the ideal way to do it. Here you can see the Caterham Seven drivetrain. Version 2 (V2) - Ford Mustang Shelby GT500 (with auto-stop, with clutch) Correct speeds change ratio: ~90-95% This is a little bit smaller and more reliavable version of the 3rd gen. And with the torque problem fixed. Here the Mustang GT500 drivetrain. Future generations For the future I have some ideas for new gearboxes generations, but they are only ideas... nothing more, and I don't know when I will can have a working prototype. I hope this long explanation can help you to understand my gearboxes family and the high quantity of models developed along the years.

Ok, The problem is the price. Probably most of you have a servo motor, but many people who buy my instructions haven't it... and a servo motor is very expensive (around 30€ in bricklink)... The RC and the manual version are almost equal: frame, bodywork, front and rear axles, interior, seats, doors, bonnet and more, are equal, it uses the same digital files. Only difference is the gearbox, and the RC has three little mechanims for motorize the drive, steering and brakes. Some screenshoots of the files(there are more files with the bonnet, doors, seats etc...): The manual gearbox, with handbrake(the sequential gearbox doesn't have it) And the new sequential gearbox

I like your point of view, but there are some things about you have not think... Many people don't want any of the advenced features, like the sequential gearbox and the functions controlled remotely, they only want the model to keep it in their studio, only for look it, like another Lego Technic set. The manual version has not any motor(obviously), but also it has around 300 parts less, and that means the manual version is much cheaper than the RC. Also if anybody wants not pust all PF elements, and only add the servo motor to the gearbox can do it without problems.

jantjauh, I got the 10.000 votes in cuusoo with the Land-Rover, but in the very far case that Lego finally release the Defender as a set, they will never launch another big technic cuusoo set... About the two versions... the manual version doesn't have sequential gearbox... just the typical manual 5+R speeds gearbox with handbrake... Maybe you think why not put the sequential gearbox in both versions... and the answer is very easy, the 3rd Gen gearbox can not be driven confortably without a motor. kevman, it is not based in the MPS, because I can't add brakes on it with the space limitations.

Yes, the digital files are finished, Jurgen has they now. Now I have a provisional part list.... and the car has 3899 parts!!! more than I thought... hahaha But it only has a little quantity of expensive parts, so it will be more or less 150€ cheaper than the Land-Rover in the full RC version.

I understand perfectly your point of view . Usually higher speed is better, and you are right with that. But for me that is not important, for me is enough if the car can moves well using all gearbox speeds. Because as you now with big cars is impossible get a good speed :cry_sad:. I know I use the 100% of the PF motors power, but I never have had problems with that, all my PF motors and IR receivers works like the first day. I burned a IR receiver 3 years ago, but that happened because I connected 2 RC motors to the same output and running at 100% :laugh: Just for some extra information, the gear ratio in fifth gear is 1:0.66 (1.67*1.67*0.33*0.71). Taking 300rpm under load of the L-motor-> 300*0.66*81.6*0.0001885(unit conversion constant)=3.04kph.

Thanks Paul ;) Can I have measure the speed wrong and the actual top speed is 2.5kph? Maybe, but does it changes something?... In any case in your caculations you have forgotten a gearing up between the drive motors and the geabox. This event: TrenBrick http://www.alebricks.com/2013/09/10/trenbrick/ It is a event in the Train Museum in Madrid.

I am still waiting... Yes, it seemed very cool and funny, I'm looking forward to seeing the video ;) Yes, I will release both versions: RC, like it is showed in the video and other completely manual.

I will explain the differences between generations as soon as I have some free time. Now I am very busy again... I have to finish a new HUGE moc to present it this weekend in a event in Madrid.
