Thanks for your review. It's always interessting to see the different point of view :) And Technic for teh win !

Oh yep Allamp, I have already seen your MOC but I didn't know it was able to drive. So I'm the second one to build a working jeep hurricane :p @Meatman :Coney's creation is not really a jeep hurricane for me because it works more like a bulldozer ( one motor per side of wheels). Also, to be clear my paypal adress is the e-mail adress I have posted above.

Thanks everybody ! The video was posted on the first post but I hadn't put correctly the link. Here it's : Alasdair : I have built the jeep with the building instructions and haven't found any problem. Honnestly, I don't see where's the problem with the sub-assembly step23? And I don't understand where you want to put the pin 1/2 ?!

Hello everybody ! It's long time since I have posted a creation on eurobricks. The one I present to you today is finished for two months now but I have been very busy working on the building instructions. Building instructions for this model are avaible.They cost 9 euros. Contact me at guillaume.meurisse@gmail.com to buy them. Payement by paypal (with this mail adress)or iban. I will then send you the pdf file. First of all, I want to thanks some guy who has really helped me : -my father who helped me resolving some problem while creating the building instructions -Nathanael Kuipers who also helped me with the building instructions and whose I spoke about my model -Jurgen Krooshoop who gave me some advice to modelize quicker my hoses -PG52 who lent me freely some parts to finish my model -and further : blakbird, nico71, tony_st170,... Let's introduce the real jeep : Presented by the Chrysler group as the most maneuverable, most capable and most powerful 4x4 ever built.It owns to v8 engine which delivers each 335 horsepower.Chrysler used its multi-displacement system in the Hurricane. This system allows half of the cylinders in an engine to be deactivated when the vehicle doesn't need as much power.(source :howstuffwork). But the most impressive thing is the steering of the jeep which is able to mill around.To do this, wheels take a strange position and right wheels turn in a different direction than left wheels : And here is my lego model : It tooks me approximativly 150houres to build it and I think that it's the first jeep hurricane which really works (without beeing pretentious). The look is quit characteristich and I think it's not difficult to recognize the real jeep. I designed meticously all characteristichal elements such as cradle,motors,backgate,bullbar,...without forgetting about optimization. Optimization means lightness, a very usefull property to have a working lego jeep. Finally, the model still weights 1kg900 which is quite heavy. Fortunately, the model is still able to mill around like the real one does. But you will hear that motors struggle in high gear because most of the flat are too rough. Without forgetting feet-step : Here is the functions list : -Integral propulsion with two speed gearbox -Steering on both axles -Independant suspension with caster angle,portal axle and king pin inclinaison -Mechanism to switch from normal to zero turning radius mod. The four wheels are powered by two L-motors. These motors are connected together via a differential to compensate the difference of speed between both motors. A central differential is used between right wheel and left wheel ( unlike our traditionnal car where central differential is used between front and rear wheel). On the above pictures, you can also see the transfert case and the gearbox used to change the direction rotation of one pair of wheel. The steering works with a M-motor. It can be disconnected to change from normal mod to zero turning radious mod with this gearbox : The change from one mod to other mod is done thanks to pneumatic. Sardo-autovalve is used for this function.Two pneumatic cylinders (connected on the racks and moving with them) extend and by doing so, bring closer the links which pull the hub, so the wheels turn. As racks are not especially in their neutral position, I have created a system to back them to the center. But racks are linked with a 12t to the motor, so to move racks, the 12t gear need to move and the motor also. It's for this reason the M-motor is disconnected at the same time by a big pneumatic cylinder. During all these changes occurs, a last one happens : the change of direction rotation of on peer of wheels. It is done by the pneumatic cylinder under the frame ( no more space inside). The blue pin is used as a stop because there are too much slack between rack and wheels. As you can see on the above picture, wheels turn much more than cv-joint can. For this reason, I have shifted from one stud from the lower triangle the cv-joint. I have plenty of things to say on this model but I prefer to be short and comprehensible because my english is not enough advanced to exprim what I want exactly to say. You can see all the pictures of this model on my brickshelf galery : http://www.brickshel...ry.cgi?f=510206 And here is the video : Last but not least, I have spend lot of times creating the building instructions so everyone can build my model ! They cost 9 euros. Contact me at guillaume.meurisse@gmail.com to buy them. Payement by paypal or iban. I will then send you the pdf file. I'm very happy with this model and after all the time involved I'm pleased to finally present it to the community. It's time to build another creation. As usal I'm open to any comments and remarks ! Guillaume.

No, they speak english in the lego company ! Btw,it's a great new to hear that you are now a lego designer ! I hope you will design plenty of new very useful parts such as hoped by most of the lego technic fans !

It's simply amazing ! I don't imagine how many times you spend developping this ! The people who will see it in real life are really lucky :)

It is strong enough thanks to the vehicle weight. It can only pop out when the car is not on their wheels.

If it can help you : It uses portal axle so it's big. Also, if you want to use portal axle, I advice you to use 8110 parts, more efficient, as I use on my new hub.

I don't consider this as a rule, it's simply the better way to haven't any gear skipping.

I really love your idea Jovel ! I guess it would be quite interesting for a lot of other MOCers. Personally, I would like to see an epycicloidal geartrain from lego, so you can put important hub-reductions or build some automatic gearboxs. And strangly Crowkillers, I would prefer the connector you show with two pins holes ^^. Mescalinum : one part more I hope lego will ever release...

Totaly agree with this ! It sounds for me like an easy solution for someone who don't want spend much times to develop another solution. And yes, I'm a purist :)

Your example is not correct as both L motors are not linked together. One drives left wheel and the other the right one.

My workplace :

Yes, but if his goal is to participate to the competition, he had to deal with their rules

It's strange to already begin to work on a model without knowing the rules. Image you begin to use motors and one of the rules is : no pfs motor inside your model ...

So,I'm wainting impatiently these interviews but I understand it take quiet some times to do them ! And yes, I consider NK as a lego designer :)

I don't really have that problem as I try to build only with my parts and I don't build other people MOCs. But I often buy separate parts from lego and it's frustrating to see that recent parts are already out of sale... Concerning Bulklug, you can buy only parts which are in production so I don't think it will resolve this problem.

TechnicBricks should really interview more great builders !

Very interesting. Maybe am I going to participate :)

They are just magnificient, all. But my prefered is still the green one :)

And image to help you to understand how to create Ackermann effect : And a solution used in one of my creation ( a jeep) :

@Hopey : your solution will work only with servo-motor. M motor doesn't turn at the same speed,so after a little play with your MOC, wheels won't be able to align correctly. I have already tried this solution and it doens't work well.

Don't use a driving ring and chang over catch, they create lot of slack,not wishable in a steering system. I would use a translation system with 3 gears in one mod and two in the second ( as showed above).

Does somebody know why is only the first inner gearwheel in metal ?

It's a nice creation which looks beautiful with this orange color ! I'm not fan of the 4motors solution but I admit that you can gain in performance by doing so. You can create building instructions without disassembling your mercedes by using a software such as mclad or sr3dbuilder.
