        I need every part list.
        I have 1 set of 10261  and some sparebrick. I'd like to buy only the extra bricks

    I think I finally got all the parts I need for this. I assume this set will not be moveable without a board underneath.  Any recommendation for a board?  Plywood?
    • 11 months, 2 weeks ago Labsrl Level 8 Designed this MOC DESIGNER
      Exactly, we use a Plywood's board. circa 1,5 cm of thickness (minimum for this moc)

    First to the positive the set is very big and it works sometimes.
    From 5 try it works 1 time
    I have everything structured as described.
    I needed about 35 hours and at the end the roller coaster only works conditionally which has me a bit disappointed.
    It always depends on the top of the lopping.
    What really upset me is the video posted here.
    The video was clearly made faster and looks more spectacular.
    It looks in the video in that it was made faster as if the car lopping loose create what unfortunately is not so.
    Why was the video made faster ????
    This video got me to spend $ 1000 and spend 35 hours working.
    And in the end I realize the video was made faster.
    What a disappointment

    That really makes me mad.
    • 1 year ago Labsrl Level 8 Designed this MOC DESIGNER
      the MOC works exactly like the video. it is tested a lot of times, and it is guaranteed. I can show you everytime.
      keep control the rails are in line, push lego brick well, without little steps/stairs between rails.
      control the wheels under vagons that turn well.
      There is nothing to be mad or disappointed.
      Contact me in private, to resolve. Thank you.

          i am here to answer ur question as
          i first also have the problem you have, left comment, and the author contacted me. After the loop it might fail when doing to U turn, however, i quickly try to make the coaster more fun by firstly change the U turn to mini horse shoe sharp turn, after many failure i success at the end, with no issue. so i cannot remember how i solved the problem. i didn't change anything really except maybe make the technic axle more stable (the instruction was missing 3 locations didn't teach us how to connect them, hence i ask the author to send me the photo how he connect)
          then i moc to combine with sudeen drop 90 degree fall, that was the biggest challenge overall but i have successed at the end with no fail, i can let the coaster run for hour without any fail.
          i want to say something, the motor speed is not important, and the coaster actually went very fast, similar speed to the OP, or even faster on my case since i added the sudden drop, i motorised lego motor to USB so i can control the speed, that's why i said speed is not important, i tried 50%, 75%, 100% all working, the motor speed is only to chain up the coaster to the top. if you have problem with ur coaster, the problem is usally ur loop not connected properly

          i took few video before i took apart but if u want to i can upload to youtube. i am expanding it to 4 sets at the moment as after i completed this moc i want to add more excitement to the coaster ride by giving more variety of the style.
          • 1 year ago frozenkuku Level 10
            i uploaded my test run version 2 video (added Mini Horse Shoe Turn)

            i will upload ver3 if you interest but it's really just testing my concept, i need to shortcut the tracks cos i don't have enough, hence i am going to get 4th set) it's working now so i am doing the polish now.

                I remembered now, if you have problem after the loop, it's because your post has incorrect height. the instruction due to the angle, it cannot show the post properly so u have to inspect one by one and count the height, you are probably missing 1~2 round plates on some of the post around the U turn.

    what additional parts do we need to purchase?
    can you pls list them?

    i try to add 3 roller coaster sets to inventory and click build this moc

    5 x 32123a

    • 1 year, 1 month ago Labsrl Level 8 Designed this MOC DESIGNER
      no

    Hi, I'm trying to upload the parts list to bricklink xml.  Part 35381 is giving me error. What is that part?
    • 1 year, 1 month ago Labsrl Level 8 Designed this MOC DESIGNER
      Hi
      the best way to build it is starting from 3 x 10261 and buing only the others 5 parts you need 
      You can see it on the second page of the pdf instruction or on the picture I posted
      • 1 year, 1 month ago lordevan83 Level 5
        Do you really need 3x10261 or can this be built wtih 2x10261 and some spare parts and tracks.  I'm looking for most economical way to build this.
        • 1 year ago frozenkuku Level 10
          one roller coaster = 4124parts
          this moc only 6166 parts
          so i guess a lot left overs

          i am going to start this weekend
          i will let u know
          • 1 year ago lordevan83 Level 5
            how is the build going?  do you really need 3 sets of the coaster or can it be done with 2 and some extra rails?
            • 1 year ago frozenkuku Level 10
              I just finished this morning (no sleeping till it can run)
              there are many errors on the instructions and missing steps, so i have to fine tune it.

              you don't need 3 sets, i got so many left over. i am trying to find out why sometimes the ride failed after the loop, seems not fast enough or something lose.

              i will take a photo once i tidy up the spares.

                thank you for your interest,
                we have uploaded after your suggestion, now you can also buy 2 sets with the addictional part list we have created. With the bricks you left you can also create and decorete as you like :)
                the ride is impossible it fails, it has been tested a lot of times before, and it works without fails.
                Instructions are made with Studio.
                Please send us the instructions errors you found, we can also get in touch to see the reasons your ride doesn't work.
            • 1 year ago Labsrl Level 8 Designed this MOC DESIGNER
              Now you can also buy 2 sets with additional parts. We have created a list on the Inventory. Thank you
              • 1 year ago lordevan83 Level 5
                Thanks so much.  I got my second set, and will attempt to start building this next week.
  • 1 year, 1 month ago frozenkuku Level 10
    very attempting as i just purchased 5 sets with discount
    can you pls show a random page of the instructions? want to see what's the quality looks like, thx
    • 1 year, 1 month ago frozenkuku Level 10
      and can u pls also tell us the height, width, length? just need to measure if i have enough space to display
    • 1 year, 1 month ago Labsrl Level 8 Designed this MOC DESIGNER
      Hi 
      the instruction quality comes from a PDF file born from the instruction and project made by studio.io
      Dimensions are 139,4x51,5x75h
      7kg
      • 1 year, 1 month ago frozenkuku Level 10
        It is in cm?

        the reason why i ask is some of the moc instructions such as tower bridge alternative built to london museum, the designer made everything only in one angle and current page all in red, extremely painful to read and understand and need to keep guessing and compare with next few pages
  • 1 year, 1 month ago phoenix7000 Level 10 MOC Designer
    Super cool moc I must say. Probably almost as fun as a real rollercoaster!;D
