To summarize, basing on the number of motors and hubs per 1 currency unit, the champions are: 42124 Off-Road buggy, as the set with lowest possible absolute cost, and which provides the lowest price for 1 hub + 2 motors (two identical ones!) + some suspension parts, so you got not only basic PU parts for the lowest price but also a set to build some other buggy-like RC machines. 42109 App-Controlled Top Gear Rally Car - it provides a similar number of PU components, but: is more (a bit) expensive, provides XL motor instead of L, which is not really so required for basic models and nothing more. No Tasty tires, no suspension, nothing... 42100 Liebherr R 9800 - surprisingly it comes as the third in PU components/price ratio. Due to a monstrous number of motors and hubs, so you need really a lot of them - it's your choice. You won't get their number at a lower cost even buying multiple minor sets. 42099 4x4 X-treme Off-Roader. This set is not such a bargain as upper ones, but still able to provide you some possibilities for off-road capable RC trucks with several XL and L motors and a lot of suspension + planetary hubs parts. Other sets are significantly higher in PU parts / total price ratio, so I wouldn't recommend them as PU parts sources... Additionally, I need to add that the set 42131 CAT D11T BULLDOZER beat all the thresholds, and I would never recommend you buying it as "only PU parts source" never. With its number of components, if you really need to get 2 angular motors, it will be better to get 2x 42114 6x6 Volvo Articulated Hauler for a similar price but with a significantly higher number of motors and hubs.

The variants with RC heavy duty differential should work even for relativelly big and heavy models.

If Im not mistaken, it was also presented for 42099 but the diffrenece was much smaller.

Yeah, it apperead to be a confession topic now. I also started suspecting akind of OCD because of these things but who we are if not totally LEGOed People

I rolled this question in my mind for a long time but still didn't find any physical justification for it. However, sometimes I caught myself in setting all the pins equally oriented when building something... Even in TLG official building instructions, I see that sometimes the pins are places with their slots directed longitudinal to connected parts, sometimes traversed. Did you have any ideas why it may be (if not a pure random for sure) done such differently? I guess that having a longitudinal end slot, the connection of two linear liftarms (for example) should be more firm in the longitudinal direction, as the parts won't play compressing the slot gaps, but may have a bigger play in bending. or vise versa.

Hmm, sounds like a challenge to build it following the x30 speed build steps. It worth trying

@Jim, sorry for a direct question - moving the CAT price discussion to a dedicated topic, was it a fair act to suspend the off-topic speculations, or got you any hint from TLG to stop blaming the coming release? I saw similar feedbacks to the pricing in other set-relared threads but only here I see such stop-reaction...

@MP LEGO Technic creations, as a programmer (I definitely love separating my work and hobbies) I personally would try to make these steering modes mechanically: "Crab mode" = all rear axles + front section are turned at the fixed angle. "Small steering" = only rearmost (a little) and foremost axles are rotated. "Full steering" = all rear axles + front section + front axle are turned at different angles. So, I would make two steering systems: Line #1: Front section + middle axle + A-input of "steering subtractor" at the rear axle. Using only this line you will have a "crab mode" steering. Line #2: Front axle + B-input of "steering subtractor" at the rear axle. Adding some rotation to this line together with line #1 you will additionally turn the front axle and turn more the rear axle, so it will have a bigger angle rather the middle one. * The "steering subtractor" here could be made as a differential with two inputs (steering lines) and one output. Added: I realize that it is an incredibly difficult scheme and I have never seen something similar in any of the existing MOCs but it looks very technic-ish variant ever

Holly molly! I thought it was about 6-7 models, 10 as a maximum

Ahh, that's the CAT we so needed! May I dare to know how much it weights? I guess around 6-7Kgs, isn't it?

The V8 supercars hauler is still in progress as I was quite unsitisfied with the result and is working on the a more complex "lift" to be able to lift the cars and be compact enought to take not so many space inside. @Cosimic_65, the hitch height is about 4 studs from the ground, right at level of 49.5 wheels center. I found my one more old idea unfinished. What the features I may add to this tank trailer? I supposed to use the 20T gears (or even replace them with more autentic caps) to control the follwoign things: 1st (fromt the front direction) - for someting related to the 5th wheel. Maybe it's height to tilt the tank backward a bit to unload the liquids easier? 2nd one to land or retrrackt the langing gears (supports) + lock the wheels (a "parking brake") 3rd one to control someting at the rear. I thought about the "ride height", axle lift, or, more interesting, the "load balance". I would describe it as a payload made of Heavy Bricks (used in System/City ships and trains) that can me moved rearward or backward to load the trailer or truck axles heavier. Together with a suspension (I'm working on it for other trailers) it should nicelly replicate the "good" and "bad" load balance conditions and how the truck operates under them. What do you think about this features?

Mmmm, perfect! It's like old-good Model team trucks have returned but in a smaller scale (but still being such attractive and nice-detailed). Especially, the wheel covers made of 3*3 pulleys and 2*2 round plates look great! I tried a lot of variants even with the smallest sprockets or ugly builds made of clips and bars but this simple assembly looks amazing! That's why I like to see Scale Models here - they are not only perfect models themselves but also represents some ideas that are technic-only people even may not imagine

Great! With engine cylunders covered with these bricks you may feel even some resistance due to air pressure.

If I'm not mistaken, D11 is a model's family name where D11T (like D11N, D11R, etc) is an exact model-generation name, which may have some significant differences to other D11x bulldozers. So if releases after the new real vehicle presentation it should be 99%-probable called the same, D11T, to highlight a new generation.

Guys, the UCS Tumbler will be re-released this year (https://rebrickable.com/sets/76240-1/batmobile-tumbler) and we might get a bunch of Tumbler tires and golden wheel hubs again

Yes, so far. I'm rebuilding it to the original set today)

Well, thank you, but anyways I wanted to build it by myself too (in digital so far) so will end up with building my copy of it in both cases BTW I really enjoy this process as it allows me to understand not only the model itsef better but designer's ideas too - this set really screams "hey Mr. Grohl has made me!". I has never blamed this set (cannot say the same about the new CAT however) - it have disadvantages of poor steering lock and some qestionable off-road geometry things, but being the offical set, it really amazing one!

That's the only can proove that K.I.T.T. is true here!

Now it with PU motors, new diffs, hub and planetary hubs. It took some time to build these hubs for Studio but they work like a charm now) Just a lot of missed parts are now ready for your experiments: https://bricksafe.com/files/Void_s/studio-models/42129 - 4x4 Mercedes-Benz Zetros Trial Truck.io Last steps are missed Tires are missed (in progress still) Stickers are missed (not sure if they should be added) New longer CV joints are missed (in progress still)

You can add one more gear and place the steering rack not behind but infront of the hubs.

Big kingpin offset. Due to it we have way weird axle setups including impossibility to add a differential even for mid scale sets, or quite poor steering lock to fit the wheels without monstruous wheel arches. Initially I thought about the limiters of steering angle (1/2 pins, plates etc) but then I realized that it was only a consequence of the real evil...

May be the price? Imagine how may of them thay are - they will definitelly drop the index of "Black 1L bush" over the World once released in a such number

Additionally to the truck, I finished the trailer modification. It was a bit harder due to different axles setup but I belive now it looks extremelly close to the orignial configuration. A free instruction for the truck is ready: https://rebrickable.com/mocs/MOC-85964/VoidSerpent/42078-mack-anthem-doubles-mod-70490-tires Updated trailer is in progress.

Err, sarcasm, right? The ladder is great itself but I still decline to buy a wonderful ladder carrier

"Finally we're going to get a set that deserves to be a great MOC but now complain due to its price" << it's a joke, no pun intended Seriously, I am really disappointed by the functions/price ratio with this set. I understand 42100's price with its juggernaut size and a fantastic number of motors and hubs ever inside. I will never buy it (as I will have to sell my car first, so I'm OK with not buying the things which costs a fortune ) but I really glad to watch how it works and how TLG dared to make it an official set with all their restriction and rules wich make the whole process in 10 times harder than just building a huge MOC on evenings. But as for this set I see no any justification for this price with such poor functions. Additionally (maybe its only me) but I see these linear actuators placed outside with all these angled thin driveshafts surrounded the body like these weird "attachments" rather than a logical part of the whole machine:
