    Technic 2019 Set Discussion

    Not that I can remember. In past years TLG managed to get the sets to Jim and Sariel in enough time for them to have their reviews ready and available a month before the sets release, and decades before that we got full colour catalogues showcasing the entire year with lovingly crafted imagery. But the last few years haven't worked out that way. So who knows! On the one hand it's a real shame. As a community we have less food for thoughtful discussion and our first impressions are based on leaked grainy images. Darn those counterfeit fakers, they can take their product and wipe their megablocks with it......ehem. But on the bright side, eurobricks members have told us about some very exciting things, like the new SUV planetary reduction hubs. It's enough to create suspense but not enough to spoil that suspense by giving away too much, like with clear pictures or videos of the new parts. But suspense can soon turn to being tired of waiting until the final product have a much harder task to make it worth while. If only there was a selected panel of trusted fans that could be given more of a glimpse

    42100 Liebherr R9800 Excavator

    Yeah. A subtractor is usually controlled via an up/down stick and a left/right stick where as 42100 appears to be driven from two up/down "sticks". I also don't think the real liebherr r9800 would be driven by a subtractor.

    Future Set Wishes and Speculation

    Sintered powder metal gears might be worth the added expense as it will be under more torque, and therefore more stress than the planetary set inside PF motors. Bearings might also be needed due to lateral side loading of the wheels forcing the gears to unmesh and jam. The 1:4 reduction also makes sense, as when the sun and planet gears are of equal size, and when the sun is the input and the planet carrier is the output, you get a 1:4 gear reduction. If however the outer ring gear is the output you get a 1:3 reduction and a reversal of output rotation relative to the input rotation. In real life it's often (if not always) the planet carrier that's the output.

    Only 3 days till New York toy fair. Wonder if we'll get any more info. I'm hoping for more on the SUVs planetary hubs!

    TBH I don't see countries like China and India giving up coal in the near future either. Maybe I'm wrong though.

    Seems like a good reason to celebrate these monuments of engineering now rather than later.

    Really? Manually driving regular LAs is tedious enough, let alone ones twice as long! But you wouldn't get anything new with 42082. And considering it has two battery boxes, 7 motors and over 4000 parts ide say it's driving ability is respectable for an excavator. Not great for an off road buggy but then it's not an off road buggy, it's a whopping excavator.
  8. I don't know for sure but to be on the safe side I would limit the speed and torque to what the motor delivers when powered. So if the motor runs at 400 rpm, don't spin it faster than that. You can easily spin it way faster if you push a model along and the drive train is strong. This may lead to the motor generating voltages which the internal components wasn't designed for. And if it delivers a maximum one unit of torque when powered and stalled, don't apply any more torque than that. It's VERY easy to exceed this amount of torque when turning directly by hand. The gears inside have tiny teeth and sit on thin plastic pegs. They are more than strong enough for normal use, but they are still small bits of plastic.
  9. Or how about, with a limit of around 180 parts each, you have to build two completely different pull back vehicles of different colours and a third combined vehicle using the same parts.

    Panels used in this way are very strong and rigid, excellent for chassis that don't bend, like in the trailer for the Mack truck.

    If the reports of new larger CV joints and 4:1 planetary reduction hubs are correct then Lego universal joints are no longer an issue. There shouldn't be any need for axles as thick as the wheels with motors in them, as that is indeed boring and unrealistic.

    42100 - Still a toy?

    I seem to remember Motorola was working on a small touchscreen device for Lego. My Blu-ray player can connect to the internet via WiFi and many devices that are not smart phones have touch screens and Bluetooth. So all the tech exists for them to create a non smart phone separately available alternative. Ide be very happy with that. But you guys know how I like to push things into the realm of coolbutnotinamillionyearsson! So now imagine this. You have this touch screen Bluetooth and WiFi enabled control+ central control module with touch screen in a Technic format, onto which you can connect other input modules (also available separately). These could be push buttons, proportional control sticks or whatever. This means you can build whatever controller you like with as many physical inputs you want in as many combinations and orientations you can imagine. You want a control stick to go from being up/down to left/right, just detach the module, rotate and reattach. This will work for when you want to download the control+ presets for future set releases (or create your own custom presets on the computer using a free control+ preset designer program) for as long as the internet can be delivered to a device via WiFi.

    42100 Liebherr R9800 Excavator

    @TeamThrifty my comment about lack of authenticity was more to do with the LAs than lack of complex gearboxes but you are right, function selection gearboxes aren't realistic either! But that would at least be more interesting than (motor, gear, gear, LA) X 7. But I do get it and I'm not complaining either. Control+ is a massive investment and they need a model to show it off, just like 8275 did for PF, and 42100 does that very well. And no-one is forcing me to buy it. I am however grateful for the option to buy what is practically a lifetime supply of control+ in a single set, and for the fact that these large expensive options exist should I change my mind, and for the cheaper SUV alternative as I'm really looking forward to seeing it's new bearings/CV joints.

    That's the difference between cost and value. 450 is a lot of money, but 11 cents per piece with all those motors and two control+ hubs really isn't bad value.

    That's probably the B model with downloadable instructions only
