[MOC] Large helicopter
steph77 replied to Jeroen Ottens's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Typically what i was expecting! Ahh those helicopter Mocs are always a little bit of challenging our brains! Pleased to ear that my work may have inspired you ! Maybe you could replace this 3blades rotor by a 2 blades one (likely more credible as the main rotor has 4 blades) Go to my general topic and look at the 'liberator'. I used the mini turntable and it work just fine. With a little more headache , it may be possible to convert it in a 4 blades one. I'll have a look at it and let you know the results. This could make this one even better. ...By the way, i build your swashplate today, and things goes wrong for me. Except for the collective movement that goes right, impossible to inclinate the swashplate, it locks itself due to the geometry of the pushrod system... I guess something was wrong in my built, or, in yours, the maximum angle possible for the swashplate is very tiny... I'll have a very close look at the picture below to see how you've routed all the commands. Thanks for sharing this! S. -
So, What i propose to you is just to take a deep breath and then post this JCBMoc! I'll be pleased to see you back in this futur topic. You never have to be afraid to share your model. Even if it's build ids Under the usual quality on this forum, there will ALWAYS be something interesting, new approch, new possible use of part..etc. So, please, post it! S.

[MOC] Large helicopter
steph77 replied to Jeroen Ottens's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Looks good! I have some questions, sir - Do you have built it IRL? I guess yes at reading your post. - How does the blades bend under their wheight? - I've tryed for long to use the large turntable to build the swashplate but i faced too much problems of stability, vibrations and overal reliability, how does your system work? - A selected view of the commands would be appreciated (only the upper part and essentially the mixing unit). Where do you mix collective and cyclic? from my experience the nearest you do it to the control stick, the best it works. It is obviously not the only way to acheived that. On your pictures i Believe you've done it directly on the rotor hub (like the real UH-1) true? And if you had a video... S. -

speeking of the Wheel distance i agree with @Milan : move the second axle to the front. For the distance between second and third axle, i guess this is variable and linked to the type of truck you build? It looks really good so far! -
[MOC] Pneumatic Excavator
steph77 replied to shimon's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
When looking at your model, and video, it makes me travel into time Back in 1984, it reminds me this wonderfull feeling when i received this: Thanks fort that. And great job, by the way! S. -
Effe's MOC Corner
steph77 replied to efferman's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Could it be because of the fact the cab seems too close to the ground? It seems to me that the space between the top of the front Wheel and the mudgard should be augmented even by two studs. What do you think? -

Maybe i am late at the party... Version 2 is better IMO. What i do not like (and i test it already on my own model) is the red fenders. The TGS has a flat lateral surface. Not sure it is the good choice for this one. S. -
CaDa is a new company in here. If i understand frustration of those who own the parts to build it and need to buy the set, Something else, for me, makes the point. This new actor on the brick theatre has understand one of our most wanted guess. It gives to Mocers the Opportunity to share their talent with the Community. Let's be clear, you will never get such set out of TLG. If CaDa invest in such high quality model (massively due to the same quality level of the designer), the Community will acces more easyly to top level builds. And, yes, we will have to pay for. If i remember correctly, the Sian cost 400€... EDIT: without RC, light, paddle shifter,.....

Technic 2021 Set Discussion
steph77 replied to LvdH's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Not agree. 4x4 is only useful if RC, a manual model has nothing to do with it. So, IMHO this sel will have - rear Wheel drive, - a factice micro engine (as we are used to see now), - suspensions. S. -

Don't expect that much of it. These tyres are at the same size than 42053 set. This will never fit with the Claas tyre that are the biggest recent tyres... -

Thanks. I'll try to take pictures of the truck primary gearbox soon. Stay tuned. For helicopters, @Ivan_M did a great job by providing free instructions.

Hi guys! EDIT: Sorry I lost the connection during the editing of this post Some improvement about this bike: - Add front disk break calipers - Add a proper saddle - Simplify the rear end and add détails on the oscillating arm at the rear - Change the color scheme - add a windshield So here it is:- 36 replies

BMW S1000/RR
steph77 replied to steph77's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Thanks! And it's finally done :) As you can see the front end is done, it's been quiet tricky to get this results but I am happy with the smooth curve of the front and integration of the two headlights. I recolored some parts as well, and get this 50 shades of blue colorsheme that fits well with the race spirit of this motorbike. I also build a stand that really hold the bike correctly and firmly. Looking at the front end the complex shaping of it allows a cool render of the noze's curve, integrate some dynamics lines in the design. I do not use the windshield of the Ducati that I find odd and I prefer using a simple flex tube to suggest the windshield's limit. You can also see that the lower part of the bike has also get attention with complete panelling and details The back view shows a racing spirit The borders of the fuel tank have also been carefully designed with the major holes finished with 1X5 panels. I must say that finding all these tricky angles was fun to do and research... The shifter with the 1/2 2L liftarm that shows wich speed is engaged and also acts as a limitator so getting from 4th speed to first is not possible. And a blurry (sorry) view of the rear suspension system. Multilink, it gives the opportunity to change setup by moving the attachment point of the 5L 1/2 liftarm on the oscillating arm. By modding this the suspensions is (as represented here) low and quiet soft or higher and sensibly harder (race mode) @ you...- 36 replies

Hi, Sorry i do not. The incoming of the 42107 italian beauty makes me change my plans. I worked on a bavarian response to it: - Shifter pro up and down - 4 speeds gearbox - front fork suspensions - Rear multi-link suspensions Actually not 100% happy with the front build rigidity and also with the very front end. This still doesn't looks like a S1000RR,Work still in progress!- 36 replies

42107 - Ducati Panigale V4R
steph77 replied to Ngoc Nguyen's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
This could be even simplyer. The Driving ring is mounted on a non-friction sliding connector, true? Why not replace this connector by the friction one?. The selector is manualy operated so it will need a little extra force to lock the Driving ring into the worm gear, but on the other hand the wole 90° lock system could be taken off the model wich results in a better design. -
Hi EB, As some oy you may know, i am a passionate AFOL in terms of aircraft and specially helicopter. I didn't ever had a closer look at how a V22-Osprey fly, and so i did. What i found astonnished me by the overal complexity of that thing. Here is a link to an article describing the whole flyght process: Find the article here The main things to remember about that all: - The osprey in vertical flight mode is globaly the same as a big cargo helicopter, with collective, cyclic pitch. Rotation around the vertical axis is done by tilting the nacelles oppositly. - In flight mode the collective pitch acts as a proppeler pitch, no cyclic ... This intricate flight control can be compared to another well knowh aircraft: the Chinook... No need to say these flight command can not be reproduced in lego. Through one single nacelle's articulation, you have the 3 links of the swashplate, one propulsion axle… when lego is limited to 2 axles trough one turntable. View of the swashplate implemented in each nacelle: at 1:25:00 So, good reading, and as final note, i just Wonder wich pilot is stupid enough to take place in such machine. Definaly the most complex, unstable and Dangerous aircraft ever built...

I see two other functions: one major and one minor one. First, and it is part of the iconic view of the model is a way to retract the wing (the whole wing pivot on it's axe) this mean the blades will have to be foldable... The second, wich is reasonnably not to be awaited, is the tilting of the blades. This last one would need, and means, that the blade command will have to pass both through the tilting pods AND through a central turntable. Building 2 functions through a turntable is easy to do and next to that manage them until the pivoting pods will be quiet complicated. Wait and see...

Based on the blades; wich are 19L long, i calculate the set dimensions: Width: 57 studs for the wings; 97! studs at the extreme end of the rotors; Width rotor 2X19L + 5studs : 43 studs each Lenght: 56 studs Height of the main cargo structure: about 11 studs from the behind until the top of the wing As @kbalage said in it's lambo review, this will be a HUGE beast. On another note, beside the large dimensions, tje inner space avalaible for mechanics isn't that big. With a superstructure of 11X9 globaly, there will not be that much spaces for complex mecha... Cheers.
