Hint: the second is better, as can be better secured (attached from up+down side rather one inner side), plus could be easily found in the modern sets. Meanwhile the first is an old and rare part that is just quite expensive now.

Ahh, I was starring at the picture with a question "and where is the alternative model?" Until I realized that I see an alternative, not an official set... It's magic!

It's a common situation now - I have heard about 10 (at least) such complains, and TLG always sent the parts replacements tot he customers. Sad, that it happened but they are trying to change it, as I see.

Well, I think it is safe as LEGO blades are harder than real-life ones and should not have so big sag to intersect. I believe the photo of your model were made is a static position (with stopped motor), so blades have big enough space to say that there is no any risk of collision.

Its rotors rotates in a counter-order (CW+CCW) and I believe are synchronized, so they may cross each other. Anyways, the rear one must on the top during the flight, while in the "landing" position, it sags down and they may intersect. Edited: they really have a single driveshaft between the rotors, so they are synchronized. Just make sure that the blades have the same gears ratio and placed properly: (>-) (>-) - one blade is placed to the gap between two others of another rotor.

Looks great, but afraid it won't work very well with crab steering mode. For this scale I still would use the straight parallelogram geometry. However, nice and compact axle!

42008 was a kind of pre-49.5 trucks, as had smaller tires, but was amazing in scope of the functions (not so many sets had PF + Pneumatic functions) and was a great resource set. I'm looking forward to to see it in the same scale, as I believe the model will come more detailed and with more detailed cargo...

Well, it may a be a different brand - nowadays many European companies consumed the America truck vendors, so it could be (if licensed, for sure, not a generic truck): Mack (again). Granite may easily carry heavy equipment. Or... the Rubber Duck? Volvo (they have a VNL models for US market but they are not "classic" ones; however the Anthem is not "classic" too) Freightliner (Daimler AG) Peterbilt/Kenworth (read: Paccar trucks) as far as I know don't have license deals with TLG.

Yeah, but personally I would prefer to have a well-detailed tow truck with some less-detailed vehicle rather two trucks with the same parts counts. However, if the "broken brother" will be a 4x2 (2 axles) prime mover (truck with cabin+frame+5th wheel only) it may greatly save the parts for the tow machine.

LOL, that is how the 1WD car should be made!

From general 2021 set topic: Likely it still will be a kind of 8285 set (but the wheels size is unknown) rather 42008. Or timtimgo's 42108 alternate. The color scheme reminds a bit the recent 42112 mixer with multi-colored body. Plus, the carne arms in different color (orange?) The pneumatic! (however it may have some PF/PU things too) Tridem-rear usually means a tow crane with a huge lifting capacity, however this wheels set (1+3) is less popular among the rotators. The dimensions in studs are: 73 x 48 x 15. That makes it very close to current 49.5-wheeled trucks. So, I assume, it is classic American truck with a lot of stickers (to support the color scheme), possibly liftable second axle and straight crane/tow arm. (well, it has an extra axle actually...) Added: As for me, it looks like an instant buy!

If only Hummer EV (electrical pickup's concept). Real 1-2-3 model were sold to China manufacturer and now are produced as "DongFeng Warrior" brand and are less known to world-wide consumers.

Because the new shape is additionally reinforced. I can't say nothing about the pin-mounted parts but vanilla pins (2L, with slot and friction sides) from 2010-2020 cracks so easily, so possibly TLG decided to reinforce the "pin" shape everywhere.

You amazingly described two tow-truck types: Rotator (with crate swiveling and therefore side outriggers) and straight one, focused on towing only. Returning to US/EU types, American-"nosed" trucks are mostly rotators while European ones are 50/50, so everything is possible. I would also add one more argument against the motorization - Control+ motors and especially hubs are expensive enough and, which is worse for 49.5-wheeled scale, are just HUGE. Really, I hardly can imagine that it may fit the hub and distribution gearbox. However, having multiple motors is even less likely, due to size and cost limitations.

Or just something is able to pull something heavy... I agree with Jundis that "heavy duty", "4x4" an other similar things may come as marketing "tasty" wording rather a real description. Anyways, I'm looking forward to see this vehicle, tow trucks (not just cranes) were presented long time ago (I prefer to skip the 42070 set as it wasn't a proper tow truck due its ridiculous weakness) and now we got longer actuators, new pneumatic and many other tasty part that may bring something new to "heavy duty" machinery. In a positive way, I believe. Forklift 42079 even being not a truly "heavy duty" loader, was an amazing example of cargo machinery and capable to lift really heavy loads.

Wow! Initially, I had a question why the rear axle is set so rearwards. And it was answered very quickly! Amazingly complex model, I like it!

Twin steering is done! truck mod twin steer - Bricksafe I must start with a moment that I preferred to save the original gas tanks (they must be capable to keep some fuel), so the chassis is 4-studs longer. It required to change some parts (mostly replace liftarms with longer ones in the chassis) but as a bonus it fitted the new 3x1x7 panels. They look amazing I believe! Now the main change, the steered 2nd axle. It is a copy of the 1st one linked to the steering wheel (exactly steering wheel, not the 1st axle), so I got two main advantages from this decision: Steering wheel controls both axles directly (like it is done in real twin-steer trucks, +10 to authenticity) The linkages go above (to the 1st axle) and below (to the 2nd axle) the drivetrain and do not make any troubles for RC-ing or other modifications. Yes, tri-drive mod can be easily attached here. Here you can see how the steering works: Dark-blue and blue parts are from original set (dark ones are static, lighter one - moves). Yellow linkage connects the steering shaft and the 2nd axle. Orange steering arm pivots the wheels. It may look weird enough (and I does I believe) but these half-stud offsets set both axles in parallels when the truck moves straight and sets the 7:5 ratio, required to have 35 and 25 degrees steering lock on both axles. The building instruction is available at Rebrickable (LEGO MOC 42078 Mack Anthem Twin Steering MOD by VoidSerpent | Rebrickable - Build with LEGO), together with free Studio file. As a bonus, the file includes some additional gifts: 3x1x7 Technic Panels (presented in 2021 models) - you can see that the side skirts are med of them Mack Bulldog figure. It wasn't easy to make it but I'm pleasured with the result. Printed 3x1 silver tiles (Mack grille sides). Hope they may help you in your models! P.S. Now it's time for the trailer...

I suppose the difference could be observed only in jumps - new tires are much harder while softer balloon tires better acts as springs.

I suppose the first modification could be a locked rear diff. BTW, interesting how the new tires are grippy comparing with balloon ones.

Interesting use of the angled ("blue seats") panels, it makes the shape very "curved".

Personally, I didn't observe any difference in the output result between your and Sariel's programs... Could you explain in detail the "something:1 or 1:something" problem you're talking about?

Wow, man, the models are fantastic! I couldn't imagine that "steering lock" for pullback mode can be done with quite a limited number of parts

I wouldn't say so... I still remember some failed ideas of very compact chassis where this part was literal salvation. MOCs will show the future of this part)

I would say it's more for Scale Models forum but the rat rod really amazing! I love the engine design with glasses. Makes me thing about some relations to bootleggers

Amazing idea! I see one more (may weird enough) use of this thing - a suspension. Imagine that "flaperons" shafts now a the wishbone shafts (they must be turned at 90 degrees). Red output will act as "both wheels together" suspension and may be used for the ground clearance adjustment Turntable will act as "left-right" suspension. As an option, the turntable may have a harder spring and red output softer. This assembly will work with a suspension with a kind of anti roll-bar.
