I like the way used in tracked loader's winch, that could be perfectly applied here: "fast" and "slow" knobs (two knobs with different gearing ratio, or a simple 2-speeds gearbox with a single knob) - the fast one for unloaded boom raising-lowering to move it faster, and the second for more precise positioning and when the fast once can't work normally because of a higher stress caused by a heavy payload.

That gently reminds BuWizz's three modes for on-desc, indoor and outdoor drive (otherwise you're gonna crash the model driving too fast)

Well, it means A+B models, al least for some recent years.

Can't say that I'm fully agree with that but they are definitely could proved a lot of C-Models, and it's a great resource set at least. By the way, it really comes the age of Corvette-scaled vehicles with these narrow wheels, they and wheelarches really made a fresh breath

Hell yeah! And with a B-Model! I just was about to go sleep and would miss all of them... Such a nice bunch of small sets!

Reviving the old discussion, about the old and new techniques and parts can be possibly found in this model, I can't recognize the LA's type... Seems that the one supports the crane is the old Large one...

It could be a challenge taking into account its oversized front bumper-spoiler. As for me, it looks like a mini-version of 42077 made in 42098 / Corvette scale, but for a price... It's new Control+ and seem TLG relies on it very much, so that pricing may have some background idea. I think we will know that very soon, once some driving test or interview will come.

Well, I was looking for them and it comes mostly as a tractor due to a short wheelbase (the time when the total length tractor+trailer was limited) but as for the tow trucks, there are a lot of different variations as well. Some interesting examples of them: A "big one" with a sleeper cabin, like in my model, and hydraulic arm for the front axle lifting (not so interesting in my opinion): But this rusty one looks way different: day cab hydraulic (and possibly rotatable) arm with a hook or wheels "handler", Notice the operator's set at the top of this constrcttion static crane with ropes and hooks

I'm not sure if it deserves a separate topic, so let's keep running this one... Now the F-700 is finished and I'm happy to say that it consists of 1256 parts, where 1250 of them (more than 99.5%) are from the original 42078 set. So decided on my own risk to claim is as a C-Model. The model: ready. Turned into the 42078 alternate (C-model) The building instruction: ready. I have published it on Rebrickable with the PDF instruction that, as usually, took the time comparable with the model designing: https://rebrickable.com/mocs/MOC-31395/VoidSerpent/42078-mack-f-700-f-series. Comparing with the previous iteration, it got only some visual changes like different front panel and signal lights on the roof, plus some recolors. It has no green parts, despite my attempts to cut some corners and use them without a total rebuild. It also perfectly follows the original model's stickers - have never built it physically in Anthem's parts, only technical "color vomits" yet, but will do that and share to demonstrate how it perfectly looks . Here some current rending's: https://bricksafe.com/pages/Void_s/42078/mack-f700 So far I'm preparing more details on this model, as the it's the part of the biggest plane to have a family of Anthem-compatible modular models. This one, particularly, has a wheel base shortened by 8 studs: Front half-frame - shortened by 2 studs. It was an original Anthem's subassembly but now it rearranged a bit for cabover builds. Rear half-frame - shortened by 6 studs and equals to Anthem Day cab modifications that have shorter 172" frame. Both these subassemblies have unchanged mount points so this F-700 can also get Anthem's frame (to make it Custom F-700 with longer frame), or even Tri-drive rear end for some extra heavy-duty applications. So technically, this model is a combination of a new cabin, modified front end of the frame, and modified steering linkage.

I think it really may have a difference. The possible reason is in a connection of the two halves: the LBG one is secured inside the black one by the outer edge, so it may result in two different options: The black one is a "base", the LBG one moves and hold some arm or other loaded assembly. In this case the LBG one "stands" on the bottom of Black's ring. The top part meanwhile will try to incline to inside-outside, depending on the center of mass of the attached assembly, and usually will still try to move outside, pushing to the "locks" causing their faster worn. The LBG one is a "base", the black - moves. In this case the black part now "stands" on the top of LBG's ring. The bottom part also has some play and can move inside-outside, mostly inside pushing the inner part surface that is much stronger than locks. So this option is more heavy-duty in my opinion. If necessary, I can add here a drawing with that schematic some later. So far, you can find that "locks" here, they are really very small things to be heavy-loaded: https://www.bricklink.com/catalogItemPic.asp?P=99010&tab=V

Hmm, really.. I have never thought about that as was focused on the "outer edge" but it sounds very reasonable. Thanks for the idea!

The cabin is done, finally, and I'm glad to say that it really comes close to the C-Model, as with each new iteration existing parts replace foreign ones (now it's ~90% made of 42078 parts). Now I have to finish the middle part with HOG steering linkages, as I put them lower and they must me embraced in a different manner. A little preview on how the cab is mounted: A little Easter egg: you may see even the "nose" of the golden bulldog behind the windshield central pillar). Yes, it does have this figure

I wouldn't bet that the next self-propelled crane will come as RTC again. Most likely it could be multi-axle vehicle again, but with new recently released parts: we saw a number of new crane-around techniques but they were presented only in exotic enough machines, so it should be a perfect moment to use them in a convenient crane this time.

Plus to that, the colorful scheme allows better follow the building steps ("hey, I feel I've missed that red thing here!" - vs - "ohh, damn, it's all black or dark gray??"), and, like in 42070, it helps distinguish the sub-assembles orientation that could be critical. I believe there might be more topics like "me 42070 doesn't move" if THG didn't pain left-right parts of the chassis in the different colors. Whatever we want, it goes, it happens and it's an evolution. And I like it, despite some, for sure, questionable minor moments.

Could be a crazy idea but interesting how these new tries would fit recently released Land Rover Defender. Its 42000 tires are so higway-ish and someone might prefer more off-road pattern

Just was looking at them too... I thought that they are Unimog ones but later realized that they are smaller than "tumbler" ones at the rear axle. Great news (17:07 timestamp)

Now it's finally solved: the steering wheel work perfectly! Dark-blue - the static frame+engine part; Blue - the cabin, tilts on the "white" 2x4 L-liftarms, like the original hood; Red - the main steering system, wheels+HOG; Brown - attachment for the left steering hub; Yellow - "working steering wheel" linkage, tilts together with the cabin. The main trick that the yellow ball joint is very close to center of the cabin rotation, so it works without a lot of universal joints, gears and other complicated solutions. Initially I was trying to use a real-life steering linkage closer to the wheel hub but scale limitations forced me to move the brown ball joint significantly upper... Finishing the interior and cabin tilting assembly, and then will come with the finished model.

Yeah, this particular state it one of the most liberal regarding the trailer weight and size regulations, however each weight portion must be supported by each axle... So some heavy-duty centipedes may come Looking at all these amazing trucks and trailers (and this one especially) I still recap that THG is the world biggest tire vendor, indeed!

Well, I'm doing my best keeping it "as better as". Thank you, @I_Igor, @WvG_853, @Shiva, guys, now I see I have no chance to give up! Really, it was just an accidental idea to try to make a CoE model when I saw the Daycab mods for the first time: "hey, we do have a lot of European trucks, American conventionals, so where are the 70's American COE "shorties" with wide brick-shaped cabins?" So it started... For good news, seems I solved the puzzle with "linked" steering wheel that works even with tilted cabin. It came as the easiest way behind other overcomplicated assembles with questionable rigidness... Let me take some days to visit my family and then I will finish it and publish all the details. Interesting, that Mack's F-7xx series (I just took it as the most iconic Mack's cabover series, with no background idea) is a version of Rubber Duck's "longnose" RS-712 (The Convoy movie). What a surprise!

A one more thing is ongoing... It's still in progress as I'm not satisfied with some solutions, but should be more or less done when I find out how to have all at once: working engine (ideally with zero changes to the original model); working steering wheel (with less changes) + HOG, will be fixed on the frame, as kind of air intake; raiseable cabin (uses the same pivot points as the original model). Now the cabin tilting makes the steering wheel linkage (I try to follow the original scheme with links, no gears and racks) a kind of headache Yes, the main purpose here to have "openable" cabin by any cost and keep all existing functions with no compromises. So, please welcome a draft (so far) of Mack F-700! The plan is to keep as much as possible solutions from the original model and to bring it to a C-model (ideally), or a mod, at least, using a few additional parts. So it can be compatible with existing mods like RC, longer/shorter frame, etc. (here you can see that these things came with no changes: front bumper, grill, tanks, doors, front frame with the engine).

I think it may have some custom parts Well, it's amazing model, no second thoughts. I was thinking about an airplane-mounted gun when read the tile (some like 6-8 barrel, rotates very fast etc.). Next to it, I saw the vehicle at the preview picture and said "hey, so it's a cannon that shoots at airplanes, like AA". But still never realized that it really shoot the airplanes themselves. What a mindtaking surprise! By the way, nowadays there are a very few modes that use old "stud-age" motors. Great use of it as a fast and compact solution!

It depends on the torque. The best way to save them is to gear-up the drive train that comes through the CV or Universal joint, but keep in mind that additional gearing up and down causes additional friction.

First, I would put any other motor to exclude its "clicking" and then inspect all gears that a engaged in 3-4th while the whole transmission rotates - usually the ones that are clicking and skipping are visually "jumping". Normally, the most possible place is the gear that has the higher torque and the worse secured - it's enough to have 1mm flexibility to jump between teeth.

Because another one have a higher (slight but still enough) friction. So, you really can block one wheel and then just divide all results by 2.

Ohh, It's Godlike! I saw it at your signature for the first time and it was looking great despite the size and quality of the image but now, with all these features, it's a real work of art! There were a number of similar trucks on a higher scale (62mm wheels) but fill all thete things into 49.5... A perfect Classic Truck is here!
