Perhaps tracked truck will go nicely along Arocs...and there are cool tracked dump trucks

I have a nice rough terrain in my backyard, waiting for a nice rough and tough moc to conquer.. 

I really want to make something with wheels like that heist truck from fast and furious.. I like trucks with long suspension travel.. 
But the problem is: I'd have to wait until i can afford to get a steering servo, those ball socket fork things and longer springs.. 

Benefit for going tracked would be that i already have all the parts needed.. But then again, you can't really climb rough terrain with tracks if you don't have an excavator arm to assist.. 


Oh well, at least in the mean time, i can have fun with my little tracked racer.



EDIT:

These are the two options i can go for next: 

Tracked snow plow truck;
Vehicule-utilitaire-Gilbert-GTV-tracked-

OR 

"mongo heist truck" <-- I don't know what to call this type of trucks

mongo_heist_truck_3d_model_c4d_max_obj_f

Both are cool but i think the truck with wheels is more interesting..

Well.. Here is how the project stands now:

Twin L motor chassis. But i wonder where i should go from this.. I still have a second receiver and plenty of motors to add functions.. 
But at this point, i'm thinking about gearing it down because it's pretty fast.. (popping wheelies.)

Otherwise a good platform and it works.. However, i'm having a lot of trouble with the frame flexing near the big sprockets in the outer end.. How do you stiffen it so it doesn't bend down due to the tracks twisting it?

Found some real inspiration. Now i'm working on a steam tractor.

Very compact.. Dual M motor drive. Bottom one is for steering and top one is for drive + fake engine. 


I might need some help with the steering though.. But for now it's on a clutch gear setup. 

If it's possible, a chain steering system would be 10/10.. But if i can't figure out a proper steering system, a regular link one is fine.. 



EDIT:

The "cockpit" is ready. Now i just need to figure out a steering solution and then add the moving parts of the steam engine.. That's why that center shaft is long. It drives the wheels and the other moving stuff..

This looks like an interesting and unusual project - I've always liked steam powered things! Would it be possible to add a gearbox such that the wheels can be disengaged from the motor and fake engine, to allow it to be used as a stationary engine? Then you could build a series of driven implements to go with it.

This is an awesome idea. However, i can't get a gearbox to fit in this particular moc.. When the engine spins, the wheels spin as well.

I have finished the steering mechanism.. Not only it works, but it also has lots of steering travel and the front axle has lots of "suspension travel". 
I added an axle upwards for the "idler pulley/fly wheel" and piston mechanisms..

Here is how it stands now:

The steering works, it has lots of suspension travel and it's basically playable at this point. 
However, the whole engine mechanism thing is a disaster. I really don't like this moc anymore.. 

Should i put it out of it's misery or finish it?

Tracked truck moc! 

Driven by worm gears for MASSIVE torque but slow speed. (2 L motors)
Hitch that goes up and down and an accessory shaft. 

I used a modified version of the arocs cab for the cabin. Clever use of tracks as a back wall.

Mechbuilds projects are on a break now due to my computer refusing to get photos out from phone to pc. 
I will be back when i get a new phone. later this year. 

Future projects will probably be construction equipment.

It's a known problem win honor 7 phones that their software is not supported.. Their own software can't locate the phone that's plugged into the PC with USB. Reinstalling the software is not possible cause it doesn't exist anymore. I even tried connecting the phone to the PC with wifi using third party programs but it can't transfer photos.. Emailing every single photo one at a time would be a massive effort and a colossal waste of time. I'd rather wait till tax returns and get a proper phone that works. 

Oh boy do i hate technology.. I just want a phone that i can plug with USB, open my computer, see the phone next to harddrive and just click it and drag and drop images from phone to computer.. But no. It's just an empty folder. 
I've tried everything.. Even the USB fault bug mode thing in the phone settings with developer tools but nothing works.

@Mechbuilds I suggest you to get Android based mobile phone so you can easily upgrade it to newer version that is working with PC...at least I have decided not to use iPhone and bitten Apples :wink:

Good luck

Update:

This is my current moc:
2potYJHl.png
4x4 Offroad chassis. 

What i'm thinking about is that i could make a pick up truck style body there. But the XL motor is pretty massive. 
I could change the XL motor to an M or L motor easily without modifying the chassis. 

The question is: Should i do it and how will it affect the performance or crawling capabilities? 
It's geared: 4.632:1

It's starting to shape up to something.. I'm thinking about making it a pickup truck.

Now it's about the same as in real life.. Gotta figure out how to attach the front springs and rear springs properly.

I think i need to redo the front axle completely.. There is just no way how to connect the suspension
