    A new creation, and possibly a new world record holder in terms of accuracy (I still need to do multiple day long tests to verify this).

    Wow, what an enormous project! Fantastic work!

    My guess is that a true shock absorber wouldn't work very well at the small scale of Lego cars. Lego models don't bounce all that much because friction is doing all the necessary damping already; this includes friction in the "shock absorber" piece as well as the flexing of entire structure which is far less rigid than actual car.

    Thanks! Not really necro-posting, I plan to do some more experiments soon :)
  5. Davidz90
    Exactly. More of this, please!

    The saving grace is that the piece is light and completely unloaded when freewheeling. I would ony expect wear when freewheeling at a high speed.

    Probably longer than a spring-based solution. It can only fail by ramps shearing off/grinding down over time, and they seem to be almost as bulky as regular teeth. This is an excellent design.

    The new 64T gear already found its use With 2.25 seconds period pendulum, the gear does 1 rotation in 144 seconds. Add two 1:5 gear ratios, and we have 3600 seconds.

    Personally I have never seen hydraulic brakes on a bike Reintroduction of the flex system here would be fantastic. I like the looks of the Lego version much more than the ideas submission. Wheels with tyres are the obvious improvement, and the frame feels way too bulky.

    Exactly, there are no recesses because holes are less than 1 brick deep. Only the central axle part is 1 brick, gears need some side clearance.

    Yeah, the offfset makes them less universal, but there will certainly be some niche uses. The wheel as a whole seems like a perfect flywheel for large scale machinery (steam engine models etc.).

    First videos of 11380 road bike are appearing:

    I'd agree that it looks bad, wheels seem undersized.
  14. Davidz90
    Wow! I don't know if I'm more impressed with the car, the truck or the camera vehicles Fantastic job!

    I figured there's no need for a separate topic for this MOC. Here's my very poor, first attempt at reverse-engineering a set: The model features working inline 8 engine with rear differential and a barebones 2 speed gearbox (actuated by the side lever). Gray parts are spray-painted silver like the rims, with moderate success.

    Whoa, congratulations!

    Seems almost identical to earlier set C71004W, but with smaller base? Also, on the bottom left picture, the earth does not seem to keep its rotation axis still. Probably editing error since the mechanism seems to have this feature.

    Edited the first post since Reddit post (as well as some other sources) got taken down. This is weird...

    Before building a better tail, I tried to make a typical paper plane-like structure. With low aspect ratio wings, the whole thing was much more rigid and stability problems were mostly resolved. However, such a wing is not ideal for gliding, and the already mediocre performance became just terrible. Back to the slender wings. I will try a Wright Flyer style canard configuration to squeeze a bit more lift out of this design.

    For anyone interested, repainted model T rims don't look that good and I have no clue how to dye the tires (spray paint didn't stick).
  21. Davidz90
    Exactly this. Also ,the 64t gear will be a very useful addition for making large gear ratios, especially if it can be matched with 8t at some reasonable spacing. Even with 16t (which meshes with it at a regular spacing), a chain of 1:4 ratios (16:64) may have lower friction than multiple 1:5 (8:40).
  22. Davidz90
    Apparently the bike has a freewheel mechanism, e.g. one way ratchet inside 24t gear. So many new, useful parts!
  23. Davidz90
    Wow, what a cool idea!
  24. Davidz90
    True, that shouldn't be too expensive.
  25. Davidz90
    Let's hope building instructions and parts list will become available online. Or maybe I'll try to reverse-engineer it myself. Model T rims painted silver should work decent enough, I think. The body color is dark azure, yes?
