    It is thinner than the small pulley tire (2mm round cross section), but it is the same hardness - not soft like a rubber band. Same here! But I did manage to get a few tests in today, so will be starting a WIP topic soon...

    Normally my sets get put on a shelf, and then get the "I just need one part" syndrome... only sometimes do they stay there long enough to collect dust . With my MOCs, I tend to keep them together much longer - unless I make instructions for them, which in that case I take them apart quite quickly.

    That is not it, it is a tire that is very similar to a rubber band. Have a look at the bottom of this page: https://www.bricklink.com/catalogItemInv.asp?B=9781591747697 You will see the note: "Missing 2x O-Ring shown in parts list" That is the part that fits over the large pulley. So I will create the Bricklink part myself (because I have it), and then request an inventory change - although this will take a few days. Problem solved!

    As far as I know, it is a Lego tire. That's what I thought, but all the wheels I am using are smooth, and I currently only have it geared up 3:5 - if I change it to 1:3 (which I'm also going to test), the theoretical top speed would be about 92km/h!!! By the way, what's the gearing you are using?
  5. mocbuild101
    I not, I only spent half a day testing that - and then I remembered the GPS in my watch. I have been building, and my first car (2 buggy motors) has a theoretical speed of about 47km/h , but I'm still waiting for some good weather to test it... But not yet over 40km/h, right? I know that there are 2 in the "Klutz crazy action contraptions" book.

    One thing I forgot to mention: If you want to quote a post from another topic - but want it to come up like a normal quote - all you need to do is quote it in the original topic, and copy/paste it in the other post - in the other topic.

    If you manage to make the rest of it to the same scale, it will be amazing!

    Your question is a bit hard to understand... But if you are trying to put 4 XL-motors on 1 rechargeable battery, it won't be able to power them.
  9. mocbuild101
    I'm mainly only having problems with using a torch... I need to get lasers! Well... yes - at least until I get above 35km/h. (although 40km/h+ is my goal!) But I won't be doing any testing today - it's raining! (yeah, not doing it inside anymore)
  10. mocbuild101
    The light sensor won't be able to detect the light of the torch, but yes lasers would be better - but I don't have any at the moment. I hope to be able to make it work better outside (and inside too!)...

    In the top-right corner of every post, there is a tiny symbol you can click to get the link to that post. All you need to do is copy-paste that link in your post, and it will come up automatically.
  12. mocbuild101
    Yeah, I've got that - but the problem is: I can't use the GPS inside, and I can't use the Mindstorms setup outside.

    Here are the instructions: http://www.bricksafe.com/files/mocbuild101/drift-racer-chassis/2WD Drift Racer Instructions.pdf And here is the 3D file: (you might need it for where to put the PF wires) http://www.bricksafe.com/files/mocbuild101/drift-racer-chassis/2WD Drift Racer 3D file.mpd They took longer to make than I expected (partly because of the recent competition to make the fastest Lego car!), but at least it meets the high standards I set for my instructions. All you guys on Eurobricks are getting early access to the instructions, because I won't be uploading them to Rebrickable for a few days .
  14. mocbuild101
    No, except for the video option.
  15. mocbuild101
    It doesn't have any modes, it's kind-of just: turn on -> use -> view data But I think would be reading every 4 seconds (or about that) - because refresh of the speed on screen is slow, but I should be able counter that by going at top speed for longer...
  16. mocbuild101
    Oh, $80 is too expensive for me... (I looked it up on ebay) But... today I realized I do have GPS , in my sports watch! I'm not sure if it's 100% accurate or not, but I think it might be... Will do some tests tomorrow...
  17. mocbuild101
    This:or this:or possibly both (two of each).
  18. mocbuild101
    It can handle breaking with 2 motors, but not 3 motors (like you have).
  19. mocbuild101
    Looks good! I don't know if you posted this somewhere else, but what is the GPS device you are using? - it's really small!
  20. mocbuild101
    I don't think you need to worry about months, it's only really if they are more than a year old.
  21. mocbuild101
    Oh yeah, I didn't notice that .
  22. mocbuild101
    The NXT is much slower at reading sensors, it requires a more complicated program, and sound travels slower than light . I did think about using lasers - and they would be the best thing to use - but I don't have any, and the torch I'm using can be focused into a small beam of light - so I thought that would be fine. All you would need are 4 axle/pin connectors - with some pins of course!
  23. mocbuild101
    I won't ever be finding that anytime soon, but now I think of it, there is a large parking lot near my local school that I could use - it's very smooth, and is normally empty except at school pick-up time - but it is a fair way from my house, so... That would be amazing! I have never had any problems...
  24. mocbuild101
    Train motors are quite good actually, especially if you use 2 together. They do have less torque, but they make up for it by not needing any gearing (so no loss).
  25. mocbuild101
    Nice, it looks good! I will wait for video, but you should add a link to the Flicker page if there are more photos.
