Yeah, now we're going to get it as the main model, not a sportbike. I only afraid it will have no chromed parts

Ouch, sorry, I have never seen them there... Really, it's great to see them in other sets. I remember debates on the possible use of such specific-shaped parts when Defender was only revealed, and you know, the use of wheelarches as just arches was never mentioned yet

Hey-hey, white Defender wheelarches are coming! 60350 Lunar Research Base has one of them, at least.

Emm, he's "all topics guy" and I have no doubts that surprise here are seasonal sets or MOCs (this sleige was pretty close to his MOC) or 2022 coming sets from other topics. So, looks like it is...

Sorry, is the pull-back really more diffciult? Do you compare it with Technic sets, or System/City/Creator ones?

So, it means that with some minor parts replacement it could be turned in a kind of 9398/41999/42099 "Lego-AWD" scheme with per-axle motors. I have no intention to do it at all but just wanted to notice this interesting fact.

It is a beam-liftarm with alternating pinholes - odds are horizontal, evens are vertical, like on frame sides. https://www.bricklink.com/v2/catalog/catalogitem.page?P=73507

Ohh, possibly I figured it incorrectly, sorry. I meant any trailer wheels pivot as a "steering", even just guided by just the 5th wheel position to the trailer. As for the "active steering" (well, may I call it like that?) with a steering shaft at the kingpin and the HOG mounted at the truck, yes, yours really looks a nice unique thing

Mmm, I like it, the idea of trailer steering not because of its angle to the truck (and it too, as I see) but activelly from the truck. The most lovelly thing here is the gears wich could be ommitted when using a simple regular trailer.

Yeah, and Brittish Alvis APC family as well.

Maybe an offtop a little, does anyone know any real vehicle with such a diagonal drivetrain? I tried to google it and found only a regular "longitudinal" scheme and "sided" H-drive one. The second has only central left-right sides differential and has a huge disadvantage of a driveline windup (which is even more common for plastic Lego parts). Additionally, I spent some time on these schemes analysis and now am proud to present it: Purple - an engine+ gearbox + distribution box + central diff; red/blue - independent drive "branches"; gray "tracks" show the wheel trajectories to compare the rotation speeds. As you can see, the regular scheme is a pretty convenient one and performs the best in on-road conditions. Its off-road capabilities could be improved by locking the central and possibly (optional) axle differentials. The H-Drive scheme is even simpler (and allows easy extend it up to 6x6 or even 8x8 wheels) and also needs the central diff lock. However, for the on-road use it has a slight disadvantage of fixes rotation speeds per side. So, it should be better to have all the wheels steered at the same angle to keep the same speed. Best for military slow-speeded vehicles, not so dynamically stable for fast on-road regular cars. The hypothetical "crossed" H-Drive scheme looks like an attempt to beat the "diagonal trouble" and improve the off-road capabilities (otherwise it will skid-steer randomly) with no need to lock the center differential but resulted in huge faulty: it basically impossible to turn this vehicle on the road without breaking the transmission. So, sorry, we don't have it. And now it's time for the brilliant @Didumos69 scheme: it smoothly operates in on-road conditions, as has approximately the same speed for diagonal wheels in average, and works better than H-Drive for forward-only steered vehicles. As for the off-road use, the lack of the differential locks may be taken as a disadvantage but actually, it is comparable with a regular scheme with locked central differentials (but still turns better).

Sorry for bumbing but I'm trying to build a sketch of this set using the leaked images and it looks having someting two of regual pullback motors at the rear axle, as its visible "side" is too close to the left edge of the machine, so it may be off-cenetered (to the left side) or just have twin motor giving the bigger and heavir set than regular "smaller" pullbacks released previosuly. Plus it's whellbase seems to be 3-4 studs longer than Corvette / "unoffical Camaro" sets.

TLG sometimes has even more significant "level drops" by just using the axles or frictionless gray pins which have less diameter than regular black pins due to absence of friction lines. As a fresh example I can recall 42110 Defender's a-pillars. They don't preciselly match but legally attached using both variants above.

This scheme remained me a racing cart chassis. I used to be a cart racer in a past and it had literally the same setup: short wheelbase, big steering lock, RWD and totally no differential. Due to this contriversal setup it should be driven totally different to your everyday cars - instead of slow and gentle breaking before sharp turns it should be braked in the midle of turn by literally kicking the pedal for less than a second. This actions casus so high traversal forces, so the cart inclines out of the turn and raise the inner rear wheel. It loose the traction and the cart makes even the sharpest turn on three wheels, so the rear differential is not requred. In oppostite, if you corner in a "regular road car" manner, the speed will be too slow to incline the vechicle and the result will be exactly the same you described here.

I thought it was a joke initially, like "I hardly wanted to add them... But managed to add only..." but it is Desert752's case when he is really able to do it! Now I will not be surprised to see Grave Digger ex-pullbacks with 4 buggy motors and the same external apperance)) @desert752, you did and amazing magic!

I guess the metallic plate under the orange plastic switch just fall apart (lost it firm connection) and now moves freeley not always following the switch position. It may be resolved if you just replace the battery box (they are in each and every PF set and cost a little) or disasseble yours and inspect the switch contacts.

Mmmm, they should also handle the wooden beams the best with their inner teeth.

I like the color scheme, now it looks not like a military-purposed aircraft but 24h-flight one for passengers endurance challenge Honestly, I even love these Technic-made rotor blades more than pre-molded ones, even if they are non-scaled the best to the model size.

Do you mean independent front and rear axle motorization? If they have the same gearing, it is fully valid scheme and was alrady used in even offical LEGO sets, like 9398 Crawler. Concidering a BuWizz capabilities, you may also play with some curves and make some porfiles with, for insatnce "drifting start" when rear axle gets a bit more power at earlier sarges and then equalizes with the front one, so you may get a little burnout when starting but having precise handling when move.

Just in case, the full story of a "softwheel" with in-wheel suspension: https://www.softwheel.technology/technology I never imagined any chance to see it in LEGO in such a small scale. Well done!

TLG just started with "more conventional" trucks to check the market reaction and now goes with more more specific sets. Personally, I'm not a fan of these animal-shaped trucks (they still remind me more Rio samba platforms rather heavy trucks which were the origin of first monster trucks) but I see the El Toro as amazing orange parts donor and Megal as a nice shark I can cut off from the wheels and use somewhere else

Usually the link stays in place but the whole pin falls off...

Follwing the preliminary image we might (if the desing remains the same) get the following new parts here: 4 lime "corvette"-sized wheelarches 42531. 2 (at least) lime quarter-ellipse 2*3 curved panel "extenders" 71708. I may be mistaken but I see that 3*11 curved panels have +2L leng,t not +1L behind the pinholes with door handles), so it may mean some panels extension. 3 (at least) lime small 3l panels 71682. 4 (at least) lime 1L "pipes", previously seen only in UCS Cian and Gravedigger. 3 (at least) lime 'Bionicle tooth', previously seen only in UCS Cian. A lot of lime Pin with pinhole connectors 15100. Unfortuntelly, the current (preliminary?) design of the headlignts leads to sticker-made inner inclined LED-stripes, not brick-build ones. As for their "disconetness", it can be easilly corrected by raising the "headlight blocks" at 0.5 stud higher (I propse that they are made of 2*2 plate with a side-pinhole where the headlight tiles and curved slope are mounted), so the lime slope acts as a pure continuation of 135-degress connector (#4), like I tried to do with 3-axles hub. Plus I see that A-pillars now are made of 4-6 angled liftarms, so it should be qure sturdier than 42098. Hopefully they will have stickers to hide them under painted A-pillar and windshield frame, as othwerwise they look exteremelly ugly...

That sounds sad for me... Initially I also wanted to cut the corner and use system slopes but found it as not fair solution for a Technic set. Nevermind, I will polish my version but publish it later, after the official release.

I still belive that TLG had strong reasons not to use the tractor tires for the first bunch even already having them ready for Wrangler, so they likelly won't appear in later monster tuck pullbacks... At least, it is not surprise.
