    In my opinion not sharing instructions is equally bad as the existence of bootleg companies. I hope we don't see a tendency of great models not having instructions. We are already "loosing" designers because they are in contract with a bootleg company, or selling complete models instead. I, for one, would feel kind of honored if Lepin stole one on my designs. I don't think it's a safe business-plan to make a living of selling hobby Lego designs anyway (at least for most of us wannabes).

    Hmm... I was only talking about the Corvettes. BTW your Dino was also featured. Also the Stratos. So it's not really "never".

    Maybe they confuse your models with your earlier model? https://thelegocarblog.com/2016/06/14/63-sting-ray-picture-special/

    I don't know if I'm that medicore or just can't do self-branding, but I'm a little upset that I'm still not on the map for Hungarians, even though I'm Hungarian. I registered to Mochub, but I guess they would have never considered to contact me. When I got 2nd place on the pneumatic contest, The SBrick guys had no idea who I am and I was treated like a regular customer, I couldn't arrange a meeting with the communications person because there was always something more important... Sorry for the rant, I like this model very much!

    Thanks for mentioning my design. I tried my best with the bodywork but actually that was my best then... I knew that I won't be able to make it better so at least I tried to be consistent.

    I agree with the peek-a-boo comment and also with the coherence. That's why I don't like the new Mack. Smooth, studded fully closed face with a panels-and-gaps hood and a pinholes here-and-there body. That plate at the end of the cabin with the studded 30-year-old 2x8 technic plates is extremely ugly and out-of-place. Paneling can be an art on its own. The perfect balance between parts and gaps, lines and surfaces, recurring motifs (be it a simple part fixing method) makes a model stand out visually. Like Francisco Hartley's models (he's my favorite builder in therms of visuals). It's also interesting that the style I like in others' models is not the same I would like to see in my models (I want to build more closed models and I focus on legal and exciting connections much more). It's similar to music. I don't want to play music similar to the ones I like the most.

    Not much Yes Probably no (at least not for me) no. Maybe some Duplo rails with my brother and his kid I don't have a favorite color.

    a gearbox adds zero playability yes, but adds a lot to the building experience.

    I think if you make the cabin 1 stud higher and add (if at all possible) smooth tiles on the edges and some gadgets (like mirrors, lights), it would not look "old school"

    You are right of course. My physics knowledge is rather rusty. But anyway: my equilibrium statement still holds on this situation, because the original poster implies 1:1 ratio between the inputs (since he uses simple average to calculate the output speed). The law here is https://en.wikipedia.org/wiki/Mechanical_equilibrium. Rotational equilibrium applies on single objects. It's easy to imagine that the torque on the inputs is the same if you fix the crown gear. It's also easy to imagine that the torque that's needed to fix the crown gear is the sum of the two equal input torques (if we assume 1:1 ratio between the crown gear and the output' gear, like the OP implied). It's no different if everything rotates at a constant speed.

    @Limga If the speed of the system is constant (no acceleration) then there has to be equilibrium. By system I mean the adder with its inputs and output. I don't see where I implied that the law of conservation of energy is wrong. I only said that the power that goes into the system is dictated by the load and this power can be higher than the rated power of an input* (obviously the power of the input comes from the electric system driving the motor - no conservation of energy broke anywhere, the electric system is capable to supply energy, but you'll probably burn your motor). I also said that the output rotates at 3 Hz, that's the most obvious thing. *okay, that's obviously not entirely true, only to some extent. I have to think about this part... The other things still holds (that there are equal torques on the inputs in a non-accelerating adder)
  13. Lipko
    A last note: Most free energy believers and "inventors" make the similar mistake when dealing with motors and power (for example the guy who could use a few watts motor to drive a 20 kW and clamied to have some 100000% effeciency). A power of a motor (or generator) is not the power it gives (consumes) at any given time. It's just a rated power (a maximum value which is not damaging the system or the motor/generator). The actual power output of a motor always depends on its load. No load, no power consumption. More load than the rated value, the motor will give that power, but something will burn... Same is true for a generator. If there's no electric load on the generator, you don't need much power to rotate it (you only need power because of the friction). Okay, enough of my ego...

    To support my claim, see this link: https://www.quora.com/Transmission-mechanics-In-an-open-differential-an-engine-sends-the-same-amount-of-torque-to-both-the-wheels-The-same-amount-of-torque-would-mean-same-speed-How-does-this-differ-from-the-locking-differential So basically in an open differential (which is the inverse of an adder), the torque is always the same on the two outpus shafts, no matter what their speed is.

    Pretty much all asumptions in the therad are wrong (in one way or another). In the system, there's equllibrium. You can't have 4 Nm on one input and have 2 Nm on the other input at the same time. They will be equal (assuming 1:1 relation between the input shafts gearing to the differential). So, if you have a 6 Nm load* on the output, you'll have 3+3 on the inputs. 3Nm x 4Hz + 3Nm x 2Hz = 6Nm x 3 Hz. Which is true. *there's no input torque without a load tourque on the output. EDIT: or I'm wrong? No, see next post. I think the misleading thing that tricks our minds is that we think in terms of gear rations (we are using that most of the time), but it's not the case applicable here. Anyway, physics was too long ago...

    Simply use 4 of these:

    I don't like the mix of system and technic to this extent. If system, then why don't go full system? Lego is really passing my by...
  18. Lipko
    You have my vote too, and I love that the wacky function isn't about harming the other racers.
  19. Lipko
    Hmm, I agree that openable trunk and hood is pretty important because those are functions that might be used even in a display only model. I think if you invest a little more time in your models (the world can't keep up with you anyway ) than this should be a non issue.
  20. Lipko
    Thanks for mentioning me! But I don't get one thing: in one image you use the placeholder/dummy cylinders and on another one you use modeled cylinders. How is that?
  21. Lipko
    Just focus on the model, and this is "wacky races", not "sound and paradigm-shifting concepts race". If you let the center of gravity move away from the turning-circle's center (and slightly elevate), you actually make the vehicle more instable (prone to flip over) when cornering compared to a fixed center of gravity (just imagine the center of gravity at an extremely low position). In real tilting vehicles the cabin tilting is forced and the center of gravity is moved inwards, so the cornering will be more stable.

    By the way, it's interesting that you mentioned the Unrollable by @kodlovag, because these are two models that I would build (hopefully I won't forget this when I'll have time to build).
  23. Lipko
    I like the model very much, but I'm wondering what the PTO will be used for.

    Jim is a bit lazy about frontpaging Techinc stuff... :P Anyway, You guys outrun us all. Though I have to say that I don't like those weak connections I see at many places. Maybe if you'd spend some more time perfecting how the body parts are fixed (and maybe make some trade-offs too), your cars would be perfect. (And what makes me extra jealous is that you'll find the time for building even if you have families. For me, kids are still "in the making" and I'm about give up this hobby due to lack of time...)

    You are one of my favorite builders because of builds like this
