suffocation

I see you've run into the issue with all sorts of motors. I do recall that some IR receivers - V2 maybe? - have major issues with certain M motors and perhaps some of the older IR receivers have a hard time feeding L motors, but I've never heard of issues running XL motors. How many motors have you got per channel? More than two motors of any kind running on the same channel are likely (but not certain) to suffer.

Thanks to everyone for all the ideas Haven't come up with anything efficient yet (my single-digit IQ doesn't help) but I'll keep trying.

I prefer Jim's pictorial reviews to video reviews. They're well-written, knowledgeable and objective. And the photography is godly

Hi Igor, I got the DBG sprockets from Bricks&Pieces for €1.24 each. Each sprocket is driven by 1 L motor geared down 8.34:1 (12->20, 8->24, 24->40). Quite frankly I don't think I'm going to finish the model. I started building the superstructure with my spares (plus the only two XL actuators I could afford from B&P) and found it so dreadfully boring - probably the most tedious, unchallenging and uninspiring build I've ever come across. I studied the rest of the instructions and it doesn't seem to get any better, save maybe for the arm. Anyway, I got this far and it's as far as I'm willing to go.

Holy... If this is your first MOC then I daren't imagine what you'll be able to do in the future. Awesome work all around

Awesome model - love the interchangeable turrets - and the video is hilarious as well as a great showcase of how far your shooting and editing skills have come

Thanks for the tips, lads The boom should be in the 7x7 range and some 60 studs long (folded) - it's not to scale or anything, I just need something that works consistently and keeps the kids happy, so any deviation from those measurements isn't a problem. I'm not sure a gear rack solution is feasible - I can't for the life of me figure out a way to extend the third section once the second one has been extended. Of course, one could extend the third section before the second section, I suppose. The Italian guy who build that huge crane must be some sort of genius as well as a PhD in Mechanical Engineering (his writing is impeccable, too, which is a rare trait nowadays) but, alas, his solution also involves strings. The nylon wire idea is worth a try. Worst-case scenario, I'll either go with a lame two-section boom à la 42082 or revert to a string solution like in 42009, which at least has the upside of being slightly less atrocious to re-string.

Got my B&P order at last and was able to finish the carrier. Features 4 L motors geared down 8.34:1 as well as 1 M motor for slewing. All motors are driven by 1 BuWizz unit. The chassis has been redesigned to be two studs narrower front to back (in addition to getting rid of that unsightly hub sticking out of its rectal passage), lighter and much stiffer. It now weighs 1092 g and can effortlessly carry 3 kg of ballast while moving at least twice as fast as the unmodded version (haven't tried fast mode and can't try ludicrous mode as the BuWizz is ver. 1). Even with 3 kg on top, the carrier shows no flex whatsoever, which is to be expected when you cram 4 L motors and 16 5x7 frames into so little space. Once mounted, the superstructure can be removed by simply sliding out the BuWizz unit and the four red pins keeping the turntable in place. The side panels have been modded to look smoother.

Is anyone aware of a three-section boom that doesn't use a string to extend and withdraw the third section? I've hunted high and low but haven't come up with anything; my own attemps have failed miserably. I've noticed that string solutions tend to deteriorate over time and I'm growing weary of dismantling booms and putting in new strings every time my nephews visit. Thanks in advance

Huh? Ctrl+ Large & Ctrl+ XL aren't keyboard commands. Anyway, thank you Philo!

You mean something like this? (red is input, yellow are the outputs)

100% with you. As for old age, I was already rocking false teeth when the Dead Sea was still ailing.

You'd need 1 BuWizz unit or two Lego battery boxes. But you probably don't need 4XLs unless the train's really heavy and going uphill; even then, it's also a matter of how you transfer power from the motors to the wheels.

Wow, the motors are actually geared UP there and still get the job done brilliantly. Pretty impressive and makes me rethink how I use motors. Thanks, Andy

At what speed, though? And is that good ol' British milk? Best I've ever had

Also bear in mind that 2 XLs can be powered efficiently with 1 battery box; 4 Ls will also work but will be underpowered. This, of course, can be easily solved using a BuWizz unit powering 2 Ls per channel.

Since when is paper inherently wrong?

It's silly-spell for "huge" - imagine it uttered with ludicrous emphasis But, as mentioned elsewhere, the amount of paper used for instructions - which are typically kept for years and are more likely to be sold than to be thrown away - is probably risible, even insignificant, compared to the amount of paper used, e.g., for a newspaper with average circulation in an average-sized country - and the newspaper typically gets binned on the day of purchase or shortly thereafter. Maybe someone knows where to source data on how much paper TLG gets through in a year compared to, e.g., a dirt sheet such as The Sun or a more dignified Guardian.

Enjoyed your whole write-up and agree with every bit of it (I'm also colour-blind, as is quite apparent from my pathetic "mocs" --> "my own codswallop") But the quantum mechanics part has me worried - what if the combination of too many digital instructions and too many pointlessly HEWGE models causes a gravitational redshift that tricks suicidal stars into mistaking the Earth for a black hole?

Genau. They can't always play the astronomical-part-count game, so every so often they have to pull back.

If I'm not mistaken, the instructions for 42056 were marketed as a coffee table book. If I'm relaxing with friends in front of the fire, sipping passito & vin santo and nibbling on cantucci (a.k.a. biscotti outside Italy, which Italians find quite amusing), the last thing I want is a bloody electronic device distracting my fellow banqueters.

Or maybe the "trolls" are sick of seeing random Lego fans pretending to know the ins and outs and whereabouts of carbon footprints, selective synaptic responses and ophthalmology.

No way man, CEOs are the coolest people in the world. But you do raise a good point: CEOs should sign the manuals using their employees' blood, as suggested years ago in Burroughs' "Roosevelt After Inauguration".

TLG should print much larger instructions broken down into many, many more steps so as to use at least a hundred times more paper, sourced from Pennantia baylisiana exclusively, in order to revitalise the ailing paper industry. All paper should be non-recyclable. TLG should also replace all that toxic ink with environmentally friendly seal pub blood. Finally, TLG should charge customers an extra fee based on their gullibility.
