    I guess to turn the hand-pump into a motorised pump without the additional resistance of springs. An alternative would be to use two handpumps phase-shifted, negating the spring forces.

    This thing looks gorgeous. The details are astonishing. I like the antenna on the roof Shouldn't the grey panels at the bottom face down?

    Man, this thing looks like a scale model. Didn't you have the width to install a locking differential in the front? How did you realise the compressor, did you find a solution without a constantly slipping clutch gear?

    Thanks to many recommendations i searched 8455 and found one for 57€ (63$, 48£). With a jam-stain and missing the A-model instructions but with the box. I'm quite happy about it

    Furthermore several times it stopped moving - not because the wheels lost their grip, but because the motor stalled. Indeed an inclined hard surface (wood/concrete) would be good to judge the compound, an inclined soft surface (sand/mud) would be good to test the tire tread.

    What a nice review for a nice set. I have a soft spot for pneumatics, so i'm buying it despite the messy tubes. @Sariel, could you check how well a bucket of 42055 would fit at the end of the boom?

    What an awesome car. I just love the "flatness" of LMP-cars. Can you post another picture of your secuential shifting mechanism? i don't understand it yet <OT> It's actually a wing, as airflow is allowed on the underside. When the air is only flowing over it, it's called a spoiler </OT>

    Concerning Playability: Does it stand "sturdy" enough to use the valves? As it's lighter than the Arocs i fear to move the model when making the small movements needed to get small enough movements. And while some movements can be controlled by pumping, the lowering of the arm is always critical.

    @Jim: If, by chance, you've still got 42030 assembled, you could put the new tires on it an try it on an improvised slope.

    <OffTopic> Here is one: </OT>

    @Didumos69: You're a genius! I just implemented your changes and it works, it simply works. I'll add the video when my phone and and youtube stopped resisting the inevitable Having compared my paddle shifter to my friend's one it seems i'll have to work on this one too [Edit:] and here's the video:

    This seems to be a viable solution for my problem, thanks! I always assumed this couldn't be the case because i could feel the lockup when applying the slightest force. The critical point has to be the lower red gear, sitting on the axis of 4th gear. There's the greatest relative movement. After confusing my friend with my paradoxical gearbox i'll apply your fix and tell you the outcome.

    It's officially 1:8 as noted on the upper right corner of the box. Unofficially someone calculated a value around 1:7,8 or something
  14. schraubedrin
    to clear this up, the gears after your order of pictures are: 1 4 2 3
  15. schraubedrin
    I did the Step 5 procedure and implemented your brilliant 90° indexer. I never have any gears double engaging (well expect during gear change ) Everything works quite well, if you look closely you might notice that i tested the motor in reverse-gear, when the second set of bevel gears is engaged. Its because everything else works so nice that i'm so confused.

    Hi sariel, what an outstanding review. I always enjoy your thorough "impressions" part As i'm currently fighting with my gearbox, i may have found a little error in When you connected the Motor, it was placed "between" gearbox-output and differential-input. Therefore there couldn't be any difference in wheelspeed from shifting as the differential always got the rpm directly from the motor. Thanks again for your reviews, they are the best way to collect relevant informations of the current LEGO Sets.
  17. schraubedrin
    Yes, that's exactly what i meant. depending on the gear used in this line there's an extreme jump in turning resistance. You can see that it's not stuck, because the first grey gear worked flawlessly. It's really crazy, i can turn two adjacent 16 tooth gears with my fingers and as soon as i apply more torque to the wrong one the whole drivetrain "locks up" (it still turns but either incredible slowly or with a really high torque). The whole thing just is paradoxical to me. Nope, because the Wheelspeed is determined by the differential speed (this might also be an error in sariel's review )
  18. schraubedrin
    Sure, it would be the simplest solution for me to have mounted something wrongly. I'm kind of hoping it too However, here's a (very bad) video: (Video as a link, the gear grinding is not for the faint of heart )
  19. schraubedrin
    Yes that i'm quite aware of. All gears have axial play in any direction, i can rotate any gear very lightly. I guess if that wasn't the case, gears 1,3 and 4 wouldn't run as smoothly as they do. [EDIT:] what baffles me the most is that 2nd gear has a 1:1 gear ratio between motor and differantial input. So there shouldn'd be any torque differences between input and output Also, the 3rd Gear has quite a comparable "gear path" but doesn't have any problems
  20. schraubedrin
    i hope this is the right thread, i really need your help. I'm on my way to loose my mind: My 2nd gear works only in one direction, here two videos: problem: working: trying to turn it by hand (in 2nd gear) i noticed the following: in the left line of 16 tooth gears (see picture below) only the downmost gear is turnable with suitable torque. any gear above it produces a vastly higher resistance. i can't wrap my head around this problem, does anyone have an idea what i've done wrong? [EDIT:] i hope this is the right thread, please tell me if i'm wrong

    Oh no, that is such an awesome project! Do you see yourself returning to this moc sometime?
  22. schraubedrin
    @Y0uh0u: I asked about your programming language because you hadn't mentioned it before and bricxCC is capable of several different languages. Now this question is settled [Off-Topic (sorry)]: John Hansen, the NQC-tutorial from you and Mark Overmars got me into programming. Thank you very, very much! Because of this i had never problems in any programming courses and was a research assistant in a simulated material science project. [/OT]
  23. schraubedrin
    I have to admit, that was a long time ago. I wrote my NQC-Code in a text-editor and made all the compiling and transfering via the command line (on linux) [EDIT] I just found this: http://pbrick.info/rcx-firmware/ Have you tried the standard LEGO firmware version 3.32?
  24. schraubedrin
    What an awesome model. Unfortunately i was still in my Duplo age at the time of this model reminds me of this studless 8880
  25. schraubedrin
    I just looked at the page of bricxCC. This seems to be quite a potent programming environment. In which programming language did you write your Code? Xtreme Builder might be right, i'd be surprised if the IR-Tower is still natively supported under Win 10.
