It's awesome to see you on hear again Blakbird. I still have fond memories of your visit to my house! I'm also horrified to read about the fire, and can only imagine what mental and financial turbulence such a life event would cause. I can only hope and prey you and your life are fully recovered. I still love technicopedia. It documents sets from Technics beginning through to it's first golden era in a way that is unparalleled and unique. They weren't reviews as much as they were a full showcase of every aspect of every set, where the reader was given all the information they could ever want and then left to make up their own minds. I do still visit from time to time. Your coverage was so accurate and complete that it almost feels like revisiting the set itself in physical form, which is great for sets we own but even better for sets we don't.

Custom Technic add-ons (3D print)
allanp replied to phildc's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Looks cool. What advantage would it have over this piece? https://www.brickowl.com/gb/catalog/lego-technic-ball-pivot-parts-pack-set-992185?is_gm=1 -
Exactly. In this particular case, the multiplier is actually realistic. The inaccuracies come from having a separate DnR gearbox, whereas the real car has neutral and reverse built into the main gearbox. But the 9 speed forward speeds in the Lego car are not too far from how they're done in the real car. This set is also already sold out on Lego.com in the UK and Europe according to brick fanatics.

[WIP] Cargo plane
allanp replied to m00se's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I'd say make the fuselage smaller. Googling images of cargo planes, and just judging by eye, each wing appears to be a shade under 3 times the fuselage diameter in length. You're not far off though. Would it be easier to make the wings maybe 3 or 4 studs longer? -
I've been waiting for @kbalage's review to make my mind up, and overall I LOVE IT! To get the bad stuff out the way.... 1) Colours everywhere! They gave us the perfect solution for colour "coding" with the dual molded 9 position selector wheel. Have a colour coded inside hub and have the outside a more authentic shade to look like metal gears and rotary cams. I'm not the only one in the wider Lego community that will not stop talking about all these colours and blue pins and yellow axles etc, so there it is! And now they tease us with this dual molded piece. Do more of that, only, have the colour coded piece in the middle be smaller. 2) The steering. The steering wheel and paddle shifters are still completely level, and that whole area is still too bulky. Ideally I want to see the steering wheel and shifter paddles tilted upwards a little to face the driver and have the bulky indexing mechanism moved elsewhere (like inside the gearbox perhaps). I still want the paddles behind the steering wheel, just move the indexing mechanism away from where the drivers legs should be. Doing this they could also make that area of the interior look much better, instead of opening the drivers door only to have your eyes drawn to a colour coded mess of indexing mechanics. That could all be moved elsewhere and have that area look much nicer and cleaner (same goes for the DNR gearbox, but a bit more on that later). There also doesn't appear to be any ackermann geometry and no HOG (one of the few not very realistic things I like in Technic). But at least access to the steering wheel itself seems to be better. Now the good stuff. 1) New gears! With the addition of the 8t and 18t clutch gears we now have a total of 6 sizes. And it's great to see a size that's a non multiple of 4t. What sizes are left now? 14t and 22t clutch gears, with 18t and 10t spur gears? Those 4 gears are literally all that's left to make a two shaft 7 speed gearbox with even 2t jumps between gears. With the addition of the 8t clutch gear as well, we can currently make a 2 shaft 6 speed with a mix of 2t and 4t jumps between gears, with all the clutch gears neatly arranged on one shaft. Excellent! 2) The gearbox's layout is mostly authentic, with a few exceptions. This image shows a koenigsegg lightspeed gearbox. The gearbox found in 42232 is remarkably similar in it's layout and is therefore much more mechanically efficient and (most importantly for me) more mechanically authentic than it's predecessors. I must always praise Lego for bringing out new parts for the purpose of increasing mechanical authenticity. But there are some slight differences. In the above image you can see 7 clutches. The green clutch on the far left on the bottom shaft is the reverse gear clutch and basically bypasses the middle shaft and couples the input and output shaft together, causing a reversal of direction. This is contained in the gearbox itself, and neutral simply deselects all clutches. The Lego version however, like the previous 1:8 cars, has a separate DNR gearbox between the seats, which is a slight increase in gear count and inefficiency/complexity over the real one. To make Legos gearbox work like the real one, you'd need to be able to deselect all 6 clutches in the main gearbox, however the selector drums aren't setup that way. Another deviation is where the engine is connected to. In the image above, look at the middle row with 4th, 5th and 6th gears and note the second clutch gear from the right on the middle shaft, the one with the yellow clutch activated. The engine in 42232 appears to be connected to that gear as opposed to the actual input shaft. I know that gear is always coupled to another gear on the input shaft anyway, so functionally this routing makes no real difference, but it is a slight change from reality. And finally, The middle shaft in the above image is split in 2 in the Lego version (likely to make room for the differential). The split middle shaft is connected together via an extra shaft, the one that sits beside the differential with a 20t gear on each end. Now this sounds like a lot of deviation from reality, and I guess it kind of is. But the main essence of the gearbox is there in a way that is much more authentic than previous versions. So while there's always room for improvement, the gearbox of 42232 is very much improved! The lightspeed gearbox is there, it's recognizable, it's efficient (mostly), and is a far cry from the spaghetti mess of previous 1:8 gearboxes. This is why Lego 1:8 cars are now ahead of the competition in my opinion. It's the details. 3) There's a gear position indicator. YAY! 4) The suspension and it's new specialized parts. Unlike some people, I like specialized parts. Whilst I can admire the creativity needed to realize new functionality from existing Lego parts, the fact is that's not how real life things that are at the cutting edge of performance (like koenigsegg sadairs spear) are made. They use a lot of bespoke custom parts, so Lego introducing the same parts just adds more to it's authenticity. It makes the set feel more, out of reach (in a good way), more....special. I see these shiny new parts and I see that I can't just build the set exactly how it is from my own parts collection, which makes me want to buy it. So yeah, I didn't want to love it and I didn't want to feel this desire to spend another 400 smackeroos on another Technic car but here we are! There is still room for improvement but 42232 is a solid upgrade from the P1, which I felt was also a solid upgrade from the Ferrari. This is good and gives me hope that someone in the Technic team is still listening to the fans. Thank you TLG!

Well, the theme as a whole might not be in a good place, but the last 1:8 McLaren P1 and now this 1:8 car is looking to be miles ahead of anything offered by the knockoff brands. It is a shame the steering wheel and paddles are still level and not angled up towards the driver, however I have spotted that there is a 9 speed indicator dial (exactly like the one on the GWP) included in the car itself. That is a very welcome addition because with previous cars it was always not so easy to see what gear you're actually in.

As the lights are aesthetic (in a Lego model) and the suspension is functional, I'm happy that they made new part moulds for the function rather than the look. It'll be interesting to see the gearbox, but I'm also hoping that they finally tilted the steering wheel and paddles up to face the driver, rather then them just being completely level.

Be careful what you wish for. An evil wish master might say "A modernised version of the space shuttle you say? Right then, let's have a bunch of bright red, blue and yellow visible, let's not have a micro motor, let's not have intricate and varied gear reductions and belt drives, and let's make it a car! You did ask for modernised right?"
