Efferman's Custom Parts
Sariel replied to efferman's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Efferman says he will be making it available again soon. No doubt he's busy making it even better :) -
Efferman's Custom Parts
Sariel replied to efferman's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Efferman was kind enough to get it to work for me. It seems very robust and can take a lot of torque - as you can see, it has no problem with me stopping one output while the XL motor drives it. -
Efferman's Custom Parts
Sariel replied to efferman's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Here's my little video with some of the Efferman's awesome designs: The general impression is: brilliant design, surprisingly sturdy material, but also minor problems with dimensions that makes e.g. axles difficult to put into some of the gears. Part of this is my fault, because I ordered painted version of some parts. In any case, this is something rather easily fixable. -
Purists, sharpen your pitchforks ;) Many thanks to Efferman for designing such interesting elements and for support he provided. While I don't intend to use 3D-printed elements regularly, it's interesting to see the possibilities they open and the performance they offer. Who knows, maybe TLG will actually wake up and make some new pieces of their own? Photos & reading: http://sariel.pl/2014/10/dune-buggy/

Tachometer
Sariel replied to PROlego's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
The Lego speed computer isn't very accurate in my experience. -
Does a model like this exist?
Sariel replied to Manusdei's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
There is no truck in 60036. There is a snow groomer. There were few of these in the Technic line, recently this one: http://brickset.com/sets/8263-1 but none of them motorized as of yet. The 8275 set is a pretty good base to build your own motorized snow groomer. -
Pneumatic Hovercraft Concept
Sariel replied to anton1678's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I just gave you example that it's perfectly possible with Lego motors under specific conditions. Why would you want to use pnuematics instead is a mystery to me. It's completely unfit for the task. In terms of weight-to-pressure ratio, trying to fly with LEGO pneumatics is like trying to fart yourself up in the air. -
I have mixed feelings, having been born and raised in Warsaw. Tanks are one thing, but a monstrosity like the Gustav is nothing less than a weapon of mass destruction. It may have been less lethal than a nuke, but a LEGO model would make me uncomfortable nonetheless - in the same way I think a LEGO model of, say, Enola Gay would be seen as inappropriate by most.

Pneumatic Hovercraft Concept
Sariel replied to anton1678's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I don't see how pneumatics and hovercrafts go together, since they don't mix even in real life. That's a really weird idea, LEGO pneumatic parts are light-years away from being able to withstand enough pressure. Moreover, working LEGO hovercrafts - without pneumatics, obviously - were achieved years ago already. The conditions: external power supplies, the ungeared LEGO 9V motor, and superthin foil skin on a lightweight LEGO frame. Here: -
Audi R8 (CLASSIC) (WIP)
Sariel replied to UniverseBoy's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Agree. I'm more worried about people mistaking your Audi with this one: http://www.mocpages.com/moc.php/255126 I thought it was the same model myself. -
Audi R8 (CLASSIC) (WIP)
Sariel replied to UniverseBoy's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Well, my Audi will be different than yours in scale and many other aspects, but seeing yours was certainly inspiring :) -
Looks lovely! How is the stability looking at the moment? The mast seems really massive, I feat it will make it top-heavy.

My problem with these rims is that they don't look much like the real rims. The design is unusual, the color is difficult to match with something else - it's shinier than LBG but not as shiny as chrome. Personally, I'm a huge fan of wheels from the Williams racer, they look versatile enough. If only they weren't that wide and heavy! I was also thinking of using Tumbler's tires as rear wheels on some customized vintage muscle car, they seem to look just right.

The hulls you're showing are very cheap and seem to have very low drag, but you'll need at least two for stability, and probably much more because they have low displacement. I don't think a couple will do, I needed four for very lightweight equipment. Also, it's rather easy to separate the top part from the bottom one, and you can only attach other LEGO pieces to the top one, so this is potentially disastrous. But I suppose you could glue them together. I'm not aware of any LEGO hulls that come weighted, but there are separate weighted bricks. Most hulls are so stable they won't likely need it, though. In my experience, this is the most stable LEGO hull, you could have a dancing party on it in a storm and it wouldn't capsize: http://www.bricklink....asp?P=57789c01

So you not only have all LEGO Technic in the known universe, but some wicked Traxxas too, you lucky man ;) I guess I'll go for the 38mm wide Prolines, then. The fact that stock tires don't exactly match the look of Tumbler's tires may simply result from Tumbler's weight. And sorry for starting a new topic, but this is about finding very specific kind of tires, while the other one is about general-purpose 3rd party tires
