    A better question might be why do you want suspension? It doesn't work well on almost all lego vehicles for the purpose of improving ride quality and traction. What it can do is keep all the wheels on the ground, even if they're not loaded significantly. If that's what you're after, then springs at full compression under load isn't actually bad, as they'll extend to keep a wheel on the ground as that corner starts to lift. Just an idea..... I also find the F1 style suspensions with the yellow hard spring shocks don't actually work - you're getting suspension movement mostly in the plastic support structure deforming rather than the springs doing anything meaningful. In other words, it looks correct, but doesn't actually work as you think it might. A curiosity would be if the torsional stiffness of a brick built model is much higher than a technic style unit and might therefore work its suspenders harder.....?

    Are you a lego expert?

    I'd be willing to bet that a panel is much cheaper than an equivalent pile of liftarms, but provides stiffness and light weight, together with a simple sticker surface that you can't match with liftarms. When you look at panels covering working innards, 8258 control bay for example, you get a lot more working space inside as well compared to a full 1 stud thick wall of liftarms. The square ends also join together nicely, where liftarms give you a pile of assorted gaps and holes - like the rear of the arocs cab. Imagine how heavy Lucio switch's fire truck would be if it didn't have panels!! In short, given how fiddly the pneumatics of the 42043 are, I don't think the concept of panels to make build faster for those with short attention spans has any merit. You can't replicate curved panels with liftarms either, so much of that argument dies away with only a small portion of panels being flat.

    nice model and the photos in the snow is great presentation. I can see i'm going to have to start looking for more red #3 connectors!

    Search your local lego site for "instructions" eg https://wwwsecure.us.lego.com/en-us/service/buildinginstructions?domainredir=service.lego.com otherwise, if the set is old and not provided by TLG, google it and use one of the large array of 3rd party scans.

    wow - time to hit bricklink again. Thanks for sharing Pvdb - you have an amazing technical talent and eye for detail. I really look forward to being able to realise your magic.

    I say we take off, nuke the entire site from orbit!

    oh wow! Sometimes i forget how beautiful system lego is

    my problems went up when I started using CFL and then LED light bulbs. I have far more problems picking dark green, DBG, black etc under those lights than in sunlight. Also have problems with orange and yellow under artificial light too. My wife used to ask why I put some odd colour somewhere - now I get her to show me the correct coloured part i'm looking for if i'm not sure :D i've also been guilty of making a colour wall to help out. MOCing is pretty easy - picking colours between DBG and black in the printed instructions is sometimes a nightmare

    the string and hook still came in the set though. You can't exactly call something a C model, and expect someone to be able to build it if all of the required parts are not available in the set(s) you're calling out. Where it gets tricky is what do you call a model that relies on multiple sets like nathaniel kuipers excellent supercar mods of the off roader and f1 combined. What do TLG call the equivalent truck made out of the two 42000 series cars? so with that in mind buster, you could always incorporate an extra set with string and go for broke with the extra parts :)

    Hi Colonelprca That's very impressive and looks fabulous. Have you any closeups on your attachments to the boom please? It looks like you've got pneumatics in there. Also looks like you're using efferman's large actuator like me - what do you think of it? I've been looking at this sitting outside my office for a few weeks, wondering how you'd go about creating a replica.

    I love the numbering scheme too - perhaps TLG will steal it for some anniversary editions :)

    sounds like good grounds to return it if you want to. Sad news for future though.

    based on technic parts that i've purchased from shapeways, the tolerances are much bigger than TLG injection moulded parts - consequently, the printed parts feel crap, have terrible colours and surface finish and sometimes require further work to make the parts usable. I would imagine that asking the same things to achieve clutch behaviour like the factory parts would be exceedingly frustrating. I would think printed parts will continue to be accessories rather than usable interlocking parts for quite a while.

    does it have to steer by going forwards, or can you stop and reverse with steer, then drive forwards again? The alternate dune buggy model of the 8479 has a good example of this.

    You could buy Jaap's instructions and find out. It's an electrical solution, not a purely mechanical one, and requires the rechargable battery box, but it's simple, ingenious, expandable and robust. Perhaps he'd be willing to share the idea without a purchase, but i'm unwilling to steal his thunder and I very much like his trailer.

    Interesting approach on the wheels - I can't imagine a better solution for such a high load. A truly great model - well done!

    The general gas law of pV=nRT has the gas specific marker 'n' (or number of moles related to the atomic mass of the gas) cancel when you compare two different states - two different pressures and volumes to find a change in temperature for example. edit: as for the 'snow' out of a paintball gun, I think that's a user failure that shouldn't happen if you're using it correctly. If you don't keep the canister upright, you can get liquid siphoning into the chamber rather than the gas, and this rapid expansion behind the projectile gives you the snow. It's hard on the equipment and wasteful of gas

    Air isn't typically sourced as cryogenic, so a liquefied CO2 source has a greater change of enthalpy due to latent heat effects through the phase change than a single phase expansion of compressed air. Air (or any individual gas) will do the same thing though if you liquefy it and then compare to you CO2 cartridges.

    The 9V electric wires are easy to replace if you're even lightly capable with a soldering iron. If you're really skilled you could possibly do it with the original crimp connections but i've had no success with PVC insulation - it's harder than the old rubber stuff and distorts the copper pins in the connector before they penetrate the insulation. The added bonus is you can make them of any length you choose, which is most excellent for busy MOC's like Grazi's tow truck.

    If it's sealed (or at least the inner bags are sealed), the box is likely to add considerably more than $5 in future value. If you're going to sell it well and truely used, probably not worth the effort.

    There are a few examples, like Jennifer Clarks AC50 mobile crane, using a flat deck and small rubber tyred wheels to present a large bearing area. I've also seen an example somewhere using the hailfire droid wheels as a ring support. You could also build an example like a real one - last photo, page 32 of this http://www.defence.gov.au/id/_Master/docs/HammerHead/Reports/HHCHIPSupportdocument.pdf for example.

    The IP is mor elikely to be in the mould design than the plastic, together with operating criteria to control surface finish, shrinkage and a host of other manufacturing issues. The presence of a significant number of knockoffs/alternatives that are purported to be compatible or interchangable but don't have the same mechanical fit tolerances is what will lead to problems for TLG because of the "market for lemons" philosophy. While TLG remain hugely dominant, they won't see a huge impact from some people getting upset with poor quality 'lego' and then dismissing it entirely, but as more and more market is taken by poor substitutes, the buyers start to see all lego as poor quality and so devalue the geniune stuff. https://en.wikipedia.org/wiki/The_Market_for_Lemons On the other hand, if the alternatives are of equal quality and performance to the original, none of this applies and you're back to dividing corporate profits among an equal or growing pool of buyers rather than a diminishing one.

    Wow - really great seeing more MOC's around that move but don't have wheels. Well done.
