Term speculation would be more adequate.

And you can not drive (and steer it) when seat is turned backwards @suffocation how to integrate such amounts of functions / parts is IMHO greatest challenge. Perhaps usage of 7 x 11 frames could give enough stiffness and space at the same time Wheelbase should be approximately 21 stud (real machine has 2200mm), chassis width 23 studs...

81.6 or even 94.8 tractor tires would be nice, but I think that it would use (only) Xerion tires (or CLAAS tires); in 1:13.5 scale it could use bucket with same dimensions as in Volvo 42030 and 42081 (13.5 scale based on tires because real 4CX has 16.9R28 tires that have approximately 1422mm diameter, and overall bucket max width is 2450mm) If it would be manual version - it could be done with existing parts; we have 3 different frames for stiffness and only question is if there is cheaper to use 3 new differential from 42109 set (which gives bigger reduction 12-28 than ordinary differential 20-28) or is it cheaper to use solution like on 8110 set. I had a plan to make full manual 4cx wastemaster based on Unimog tires, but have not enough pneumatics, so project is postponed...

I did not expect fully remote, but I have just mentioned that it would have more that one for that... I would also welcome another Tractor tire size, but I doubt we will got any other than 107 x 44; my hopes were on this years Xerion, but we know how it ended... that is most plausible, but costs have final word... and to have 4 cylinder inline fake engine (as you mentioned) like one from 8110 set...Bigger pneumatics (from 42043 set) could do the job...let's be (hope pleasantly) surprised

So far it looks nice; I think it is a good idea to use similar solution like @Void_S (with his cabover Mack F700 version) for steering...

you have some reasonable thinking, and IMHO it is always a big complication if you need more than 4 RC functions (not to say that I'm now optimizing my MOCs to have "acceptable RC compromise"; if I remember correctly only 8043 set have 2 x 3 RC functions...to have all manual like 8455, you do not need such size, so it could (probably) be done with Unimog Tires. Regards

and not only one if you want to have full remote control... (question is only where to put it...since it is not small enough...and backhoe with Xerion Tires should be in 1:13.5 scale...)

@andythenorth it is model for 2020 and it could be done with XL sprotckets from Liebherr 9800. This is the first fully suspended half tracked tractor. There are other tractors with tire and Trac combination like Case IH magnum but without suspension at the rear...

Actually It looks cool...didn't think that every day car could be so interesting MOC since only super (hyper) cars or offroaders are usual inspiration for MOCs.

and red thin liftarms 1 x 5

It is Fiat Multipla...one of ugliest cars ever build IMHO

And one also at the front, only turned longitudinal to allow steering

I just think it was (in mind of LEGO designers) cheapest way to introduce C+ in smaller set, but let's say like this - I'm not impressed with look either

Edit: removed Sorry Jim for my post; now I see you were faster...

Honestly I do not care because I look sets mainly as parts packs, and new C+ incompatibility with PU system will save me money as long as my PF elements work. And when it happens that they stop working I'll see what will be my interest; perhaps I'll quit LEGO and spent rest of my life's free time with another hobby (that is on standstill for some 15 years...)

Go nuts like this one

As I mentioned before to my good neighbor @Zerobricks I was mainly thinking on chassis with 49.5 tires. Of course such giant (and global player) like LEGO would not behave as Lepin or other copying companies...LEGO is trendsetter, but they certainly read what we post here so they could use that crane as idea or something (based on scale)

Agree with that but chassis idea with 8 49.5 tires was a bit familiar to me ...

Perhaps he has damaged nerves on some fingers...only he know what he meant with that post

It looks like @Ludo Visserwas inspiration with his crane https://www.eurobricks.com/forum/index.php?/forums/topic/159720-moc-small-4-axle-mobile-crane-finished/&do=findComment&comment=3039144

It looks to me that front part is build on frame 7 x 11

Agree Most liftarms are odd numbered 3, 5, 7, 9, 11, 13 and 15l; so it is easier to make odd studs number dimensions

Lucky me, since I do not like non compatibility between Control+ and PF elements...

Thanks @Void_S. I have found that those old trucks have 8.25-20.00, 9.00-20.00 or 10.00-20.00 tires, so I can make realistic 1:15 tow truck model First posted could be done in dark azure

@Void_S I'm really impressed with your version; but there is one question - did you find other use than (as our friends over big pond say) semitrailer tractor version; is there tow truck or hook loader version? Thanks
