Thanks all for kind comments :) I will try to produce a video soon. @Doug72 i knew this moc. I found it obviously well build but however a little slow . This Moc is also a good illustration on the mast visibility problem ithat i have tryed to solved.

seen from the father point of view this might be the better set of this years. Not only it looks good but it provides two great models. By great models i mean interesting building experience, lots of simple mecha (excellent for a child to learn at technic theme) and, more important, lots of fun to play with as lego provide the forklift and some object to use with. I say that because in my whole moc collection, the moc who had the very best succes was my single farming tractor who is just in the same principle (simple mecha, various simples functions, and all manual) Just my thought on it.

Hi all, Here is an attempt at building a new forklift. My previous one used the TLG design for the boom. This time i decided to build my own. Why? Just because the TLG boom had a big inner central mecha that makes impossible for the driver to look in front of him... I solved this by using a string based mechanics to lift the first stage of the mast. The second stage is also indirectly lift by the first one's movement. The whole arm has a tilting mechanism: The model has a propulsion base on one medium size motor, a tilting mechanism based on the same one. The direction is made with a servoand the main lifting use also a medium size motor. At all stage, the power is enough. Some other pictures: Front view. the driver just can look in front of him. Good idea no? Maximun size of the full open mast The model has drive and steering. Led light are also at party. The steering Wheel is custom made using technic disk and a Polly tire I hope you'll like it. Steph

We Need Respect for the designer now. Delete this vidéo. I do not see it and i Just do not want to. Edit. Private message to lego désigner who read this website for sure. You have done some great job. We Will be there tomorow for the presentation. Cudoooos guys!

I am still wondering how they managed the sequential shifter and were it is localised in the model

So sad....same than for dedicated topic. @Jim

+1. We know already it will be one excellent set if not one of the best ever released. just keep some mystery for the few days left @JimLock it.

Jim . Milan. Time to lock....no? ..in respect to lego designers who have done some awesome work. All we know actualy is that it Will be great . 6 dans to wait.

Maybe a CVT transmission?

The central lever between seats is a regular gearbox shifter piece. So i suppose this will acts like on Porsche and be the fwd/reverse selector. i ask myself where will be localised the gearbox main shifter. it could be the same than recent mercedes AMG moc, at the back in the rear window (the only view we don't have actually).

No. I imagine à link between sequential gearbox and spoiler. Spoiler would be some indicator on wich speed is engaged. ...

Just spéculations. I think that gearbox commands the spoiler...

i think you had better remove this picture as leaked pictures are not allowed to be published on this forum...

For me its all ok. Curious about the functionalities. And great coloris choice. Way better than porsche on that point.

Not on fb...

14/10! The stunnigiest thing finaly is that 100% of the build keeps 'in system'. No crazy angles, week parts.... Great, neat and stunning design. If only lego official sets could be this quality....

OK, This question is for me, having already studied in depth the subject. It is important to understand how a tandem rotor helicopter works. Unlike a conventional helicopter, tandem helicopters use their two rotors continuously to steer the aircraft. In practice I will break down each movement by explaining what setting is used at the rotor level: 1. To go up and down The pilot pulls on the collective pitch lever, the two swashplates move down together to increase or decrease the lift of the two rotors simultaneously: the aircraft goes up or down 2. To advance in a straight line. The helicopter uses a differential of lift between the rear rotor and the front rotor. By pushing the broomstick forward, the pilot increases the collective of the tail rotor while decreasing the collective of the rotor before: the helicopter advances. 3. For lateral translation By tilting the broom stick to the left, the pilot varies the cyclic pitch of the two rotors in the same direction (the two swashplates tilt respectively left and right together: the helicopter moves left and right 4. To rotate on the spot, The pilot pushes the rudder left or right. This action causes the swashplate to move left and right, but not together, in contrast to each other. This action has the effect of creating a lift imbalance between the left front and rear right of the aircraft which induces a static rotation. In Lego, the big challenge is to build the control system between swashplates and cabin controls. I realized this command mixing system, here is what it looks like ( see video below). This prototype must obviously be compacted to fit into a credible model: The basic principle is that the mixing is done on two stages. The first mixing stage takes the collective components, the second the cyclical components. There are four inputs to this mixer: The first is that of the general collective step. By actuating the two branches of the mixing system move forward and back together. The second entry is related to the forward / backward action of the joystick. It varies the two branches of the first stage of mixing a contrario. The third entry takes the first cyclical component. It is connected to the lateral movement of the joystick. Its action has the effect of varying together the second mixing stage. The last entry takes the rudder and has the effect of varying the second level of mixing a contrario. At the output there are two settings per rotor. Each has a collective component and a left / right cyclical component. No rotor has a forward / backward cyclic component. I hope I have been clear for this long explanation. Regards, Steph. EDIT: here is a detailed view explaining the video: EDIT: here is what it could look like once compacted: And finaly the cut view of the real chinook commands: Enjoy ;)

Hi Clive! It's good to hear some news from you. Welcome back! Great progress in your build so far. This model (I do not own it personnaly) will take an enormous place on your laptray, no? keep getting this up! Steph.

hello, Thanks for comment and I hope you will enjoy your built with my model. It's true that @Ivan_M does a great job! And, BTW welcome to EB! As you are a member now, I think your Allouette II needs absolutely her own topic. I am very curious and interested in how you managed all the controls, especially in the lower part of the main mast :) @+

Fresh and well executed idea ! I like the design, lightweight and very well built. this kind of crane are quiet rare but in lego gives a famous opportunity to have fun with. I like the Lego execution of the model, plenty of good ideas out there What I do not like that much : the HOG steering, not so easy accessible and not that useful finaly. I have some questions on the playability point of view, if raising the mast seems ok, extending it is very slow due to worm gear (perfect technically and very well design for the boom), need a gearing setup to speed it up, no? Same, even if it's hard to tell with the vid) for the winch mechanism. Except that I really like your model, and I do consider the time past on it. Regards Steph

Does someone now what are the very specify things to know about the Chiron? I am not specialist in cars but as Porsche has some recognisable features what could be the function on this further Bugatti? Aerodynamics moving parts, gearbox commands? ...

What can i say? It's just perfect job you have done, Ivan. A great an respectuous thanks for your time. I really like the way you produce these instructions. In a sense it makes me feel like 20 years back when TLC produce themself challenging instructions. Remember the cart chassis who had less than 20 steps. You can obiously post in on your own rebrickable acount. Once you have a link, i'll add it to my YT description. I hope now that people will enjoy building it. Steph.

Hello, It happened a lot of things here. Just coming back from work travel and wow... So, for the tail rotor, if there isn't a conflict with the rear vertical wing it's ok form me. I am dubitative with the font panel in the nose, as my flex suggest a transparent element, but why not. As you realize the instructions and therefor pass a lot of time I friendly accept your Mod :) As final speech, I had to say that even if instructions aren't 100% perfect it gives a good base for peoples who want to build it. Having instructions made by a community work doesn't mean IMO that it dispense of thinking and reflexion during building... The most interesting part is still the rotors controls and rotor head on this Moc.... Looking at the vid of Jonhatan I realize that there is one main issue with the swashplate. My swashplate elements have been used for about 20 years building lots of helicopters and in it's current state is absolutely used so that it swip along it's axle. But the original part has a lot of friction in it's conception. I think this element needs a note in the instructions too. As an easy (but not acceptable for purist) solution, it would be useful to modify the axle and tweek it a little... I tested one method, as I own two of the swashplate element and since one is in it's original state. I took one 10L axle witch is a very common part and with a blade i planed a little the inner side of the cross axle. Removing just a little material of only one side of each of the 4 branch of the cross axle is enough to remove the friction and gain a lot of playability. the outer faces of the cross axle can be keeped intact This method preserve the rare and expensive swashplate element. Steph.

Great news! Thanks for this great work. When i follow the link i just have the picture you've posted. Normal?
