B&P does not serve Russia and nearby countries, unfortunately. Mine I have order ordered in even China and they are still traveling to me... It depends not only on the truck's weight but on a combination of several factors (I spent some time on this matter and discovered some interesting things). [Front axle load] + [necessity to work on soli surfaces] + [no necessity to operate at high speeds] - all these factors are actual for heavy dumps and other heavy-loaded rigid construction vehicles, which may easily load the front axle above the permits (and possibly sink into soils and muds). The semis usually do not use the wider front tires, as their load is distributed across the rear and trailer axles while the front axle only carries the engine and cabin. Additionally, the speed is critical for semis wich live on highways, so wide front tires with their speed limits just do not meet the desired criteria. To assume, these wide tires are a kind of caterpillars: loads a quire heavy load but by the cost of slower speed and bigger engine consumption. All written above is not actual for "super singles" at the rear axles

It it not, for sure, but even having them both for 350 EUR at a shelf during some sale, Liebherr still have many more PU componenets...

Actually, having a choice between L+XL or L+L I would take the second, as a pair of equal motors provides more possibilities for various use rather two different ones... Just my opinion.

Hmm, the truck maybe even better, personally I would love to see the 3rd encounter of 42041. At least, something with a heavy nose and lightweight driven rear may not only nicely run but also drift is properly geared.

Ahh, so it has 1st axle steered at the full angle, 2dn and 4th at reduced and 3rd fixed-driven, right? I must excuse, as I didn't realize that working engine must be connected to something to be actually driven

I don't like to be a nerd (in its bad meaning) but had the 42108 set has axles with equal steering angles? I may recall it wrong but they had longer steering arms to decrease the angle too...

The medium one. The small wasn't presented yet in the Control+ family, as least among official Technic Sets.

I tend to disagree with this opinion because of actually bigger size of PU/C+ angular motor (it really is!). As for a "junk", the PF servos may have some failures (but I didn't face them ever) but we have PU/C+ motors not so long to conclude how bad/good they are yet.

I would say a bit extended: the Buggy is better for a "light newcomer" who may need just a pair of motors ("a simply some RC set"). While Liebherr really has "a full set of motors and hubs" to build anything, including smaller PU sets - mind that the official Control+ application will work with various combinations of motors, so connecting only L+L motors, or L+XL you may fully enjoy driving Buggy or Rally car models with all features for free.

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
