  1. After finally getting the 8081 Extreme Cruiser and enjoying the build, i just had to make it remote controlled. There's so much space in this chassis! And small offroaders are always a win (Unfortunately i neither have a good camera nor a nice photo-studio, so the pictures aren't that nice.) Everything fits nearly seamless, except for my horrendous cable management: (original on the left, MOD on the right) For propulsion i used two L-Motors geared 25:28 to the wheels, steering is done by a servo. As i built this mod from my own parts, i didn't use the original Technic Gear Rack 1 x 2 with Ball Joints. The result is a convoluted mess with far to much slack. But it works well enough to drive over other peoples feet Here's the belly shot: The servo is located above the L-Motors. To insert my steering solution, i had to ditch the original fake V4. The Battery Box fits perfectly in the boot. And replacing it doesn't take more than opening the boot lid. to take it out. (It's positioned on short axles) And finally i remodelled the front a bit, closing some gaps and installing glowing lights In the end i'm really glad, that i searched for this model even though it's relatively old. It's a nice build, a good parts pack, very modable and still nice to look at. @moderators: i started this thread because no such topic existed and i didn't knew in which of the other 8081 topics i should put my post. Feel free to move/merge it.
  2. I should have guessed that you already optimised this drivetrain to death Another idea to reduce the torque on the shifter rings would be to double them. But this would be a huge step-up in complexity with questionable outcome. Whatever you do, i'll follow this thread closely
  3. This will hurt the efficiency a bit, but have you tried running the complete gearbox at higher speeds to reduce the torque?
  4. Since the motors are strong enough for the 4th gear, why not raise all gear ratios? So the gears go from 1.00 to 3.00? In the end i guess you'll mostly use the first and last gear, so the gear jumps in between only help smoothen the transition.

    8081 - Extreme Cruiser - MODs and Improvements

    Wow, it's awesome what people are doing with this set. Thanks for showing me! Unfortunately my dark age began just before this set was released, that's why it took so long for me to acquire it A good idea, as the necessary parts are pretty generic so quite a lot of people will be able to participate. Except for the steering rack, it needs another solution using current parts It's my pleasure I'd be interested what you think of it. I'm happy about your feedback, it seems to be not a bad idea to take another look on older sets.

    [MOC] Liebherr LTM11200 crane

    Incredible, that you made this a working detail. Now i'm really looking forward to the video "WIP LEGO Technic replica of the Liebherr LTM11200 crane, part 3/3" to see the boom in action. Because with the pictures i can't figure out how this will work, everything seems connected...

    [MOC] Liebherr LTM11200 crane

    I'm in awe of the size and complexity of this model. There are so many ingenious details! Until now i didn't understand every part of it, are the ends of the blue 3L pins at the tip of the boom for an extension? And what are the linear actuators on the boom for?

    [TIP] A perfect fit

    Because i have a hard time seeing those perfect fits, i recently build tools to help me find them: It's a collection of Pythagorean triples and multiples of those with axles in the corners to point at/insert in stud holes. They make building stiff constructions a lot easier and faster.

    The new Ninjago Set 70670 introduces gears that look to me like the old style gears: (timestamped video)
  10. Out of curiosity: did you try the Unimog Tires (Tyre 94.3 x 38 R) ? They might fit the SUV-look

    [REVIEW] 42094 - Tracked Loader

    Great review. You always manage to make me wanting to buy every available set Why on earth didn't they make at least one of the panel fairings in yellow?! It would fit the colour-scheme perfectly and we didn't have those since 2011.

    [REVIEW] 42096 - Porsche 911 RSR

    Are those Skid-Plates below the rear diff? It's curious that they decided to include those but not a closed underbody. @Jim, great review, as always. I'm really on the fence with this one. i hate off-colored stickers more than the fact that they are using them in the first place
  13. Thank you, that was already interesting. I was surprised how confident you're building in this dense tangle of parts without using the "hide-parts-tool" It's unfortunate that you're in the middle of the project, it's the beginning or changing big subsections that i have the most problems with. If the oportunity arises, don't hesitate to upload a longer video, even if it's 80% static image. It's perfect to watch during building sessions. Maybe you'll participate in the TC15, than there's an opportunity to record the beginning of a project
  14. Just to get a feel for the rules: Would the lander from interstellar be allowed: And what about SpaceShipOne, it needs another vehicle to get in the sky but isn't an orbiter and flies mainly by aerodynamic lift:
  15. Thank you very much for the pictures, this clears things up quite a bit. I have to admit, i thought you had only put in those 16t-clutch gears as placeholders with the complete gearbox coming later This small and compact design really surprised me.
  16. I think i understand it as far as possible without trying to build it myself You've obviously put a lot of thought in this already. It's crazy how well this concept fits in your current design language That sounds like a really solid strategy. Now i'm really keen to see you working on LDD
  17. Thanks for answering my questions so thoroughly. That's a good reason, this drivetrain may be very torquey. Would it be possible if you flip the differentials? This way you could still support the input side directly while using the 24-tooth side as locking-side. maybe if you move the gearbox nearer to the XL-motors? Using the old 2L driving ring might grant you more space. Although you might have to rebuilt the fake V8 input. On a completely unrelated note: could you maybe make a screen-recoding of you working in LDD? (e.g. with OBS) I think digital examples are one off the best methods to exchange ideas. It's just that i'm so slow using it, that i normally don't bother. Therefore i'm interested how you're building such complex, free floating structures.
  18. This is a great idea, i'm looking forward to your progress on this project. Why do you use additional gears to achieve the locking differentials if you just could connect the driving rings to the differential housing? This way you'd save space and gears. Am i guessing that the fake engine is in the rear of the car? If so, you may reconsider the placing of the cross-gearing: the gears subtract torque from the axles and standard 4WD-vehicles have more torque in the rear (for better acceleration) For the type of vehicle, this seems to be a perfect base for a SUV: not too much suspension travel but still sporty.

    Compact heavy ratchet joint techniques?

    Are those 4x4 dishes and only one Stud apart? We could help better if we knew the working space and connection points. In this tight space I can't really imagine anything stronger than the 44224 Technic Rotation Joint Disk. Although i'm not well versed in uncommon building techniques. And i guess a ratchet would need some elastic deformation of parts...

    Technic 2019 Set Discussion

    That's improbable. Unless the pictures are official we aren't allowed to post them here. Sure, there will always be someone ignoring that rule and until a moderator removes them they will be visible. After that, the inevitable discussion follows whether or not it's allowed to post links to the pictures.

    Technic Pub

    I would hope so, it has been free since its beginnings in 2009. It's the main image hoster for reddit and this didn't even change when reddit started its own hosting service With this big user base, i think charging money would kill it pretty fast.

    Technic 2018 Set Discussion

    Is there any reason this thread is still pinned and not the 2019 one? Are we starting to put the early released 2019 sets into the 2018 wave?

    Generic Contest Discussion

    I had an idea in a similar direction: How about a competition without gears? This will produce either nice models to look at or crazy mechanical linkage systems for any functions. I liked the contest where one could combine two models to create an new one. How about only giving the part ranges and the requirement that they have to come from official sets? Like this one could either use a big model, two medium ones or several small ones to be in the 1000-2000 part range.
  25. My friend made an RC-mod of the 42076 B-model but is to lazy to post it, so here i am, doing it for him and you guys He raised the chassis 1 stud and all the parts fitted without any great modification. He said it felt as if the chassis was designed to be modded this way Here are some pictures: I like how well the receiver fits in there:
