I thought I would share something I have been working on for a few weeks now (in spare time).  It's a 12x12 truck, with independent wheel suspension, all wheel drive, 2 front and 2 back steering wheel axels.  Fully remote controlled.  Still heaps of work to be done though.  

The truck I have using as inspiration is...

Looks good so far!  It looks like you're using Lego Digital Designer (LDD).  Are you going to make your GINAF dump truck model with a bed that raises up?

That is a huge project, good luck!

Thanks guys and yes it will have a raising tipper.  I would have liked to use SR 3D Builder, but I just cannot get use the controls of it so LDD it is.  

A few specifications so far...
Parts: 2357
Length: 90cm

Here's an update of my work on the 12x12 truck.  Still have a fair bit of work to do, however it's coming together nicely.  The hardest part will be designing how the tipper attaches to the linear actuators, might be something I will have to work out in real life when I get around to building it.

The whole way along this project I have been designing it in modules.  This is so I can build it easily, and also once I'v built it, i'll release the building guide.    

Pieces: 3202 - (probably 4500 by the end)

Motors:
6x XL PF Motors for driving, 1 per axle/wheel line.
2x M PF Motors for raising the tipper, 1 per linear actuator.
1x M PF Motor for steering.  
3x Battery Boxes (not yet shown in model).  

This is should be a nice model to go with my massive model team style truck.  I did want to put a 5571 Black Cat in with them to show a size comparison but LDD couldn't handle it and shut down straight away.    

[timslegos]

Progress looks great!  it will be one huge model.

[dandexter]

Thanks mate, it's almost done now.  Should have finished version 1 pictures up this weekend.

You know your model is massive when you tell LDD to rotate something and it crashes.

[dandexter]

Here is an update picture.  I'm thinking the cab needs to be a bit taller.  

Pieces: 4141

[timslegos]

The cab does look good, but i would agree that it should be made taller.

tim

[dandexter]

Cab fixed, made it taller.  Looks much better.

Pieces - 4192

Also I hope 6x XL PF motors geared down to (3:1) will be enough power.  Once i'v finished it i'll go through the model and try and make it a bit lighter.  

[timslegos]

Much better.  i would think that 6 xls would be powerful enough.  You will probably need at least 3 battery packs.

tim

[The Joker1]

Thats more like it it looks far better now.

[dandexter]

Two things I'd like to add, it's taking a fair bit of time for this project as I'm making it modular.  So it will be easy to build.  That is something I wish I had done with my other truck MOCs.  Also this my 1st real Technic MOC, only ever made a few Lego ones before hand.

Thanks, i'll have the 3 battery boxes sitting behind the cab.

I need some help with ideas on how to make the tipper raise.  Using the linear actuators I can only make it raise up around 15 degrees (at best).  Looking at the pictures of the real truck it looks more like 60 degrees+++.  Anyone know how to make a working lego version of how the real truck's tipper raises?  

Thanks for any ideas.

Decided to change it from a tipper truck to a having a combination of a crane and a tipper.  At the front behind the cab I'll add a crane, behind that i'll have a tipper tray.  I think that will make it more interesting.

I'v finished version 1.  

Design Time: Appropriately 60 hours  
Pieces: 5,559
Length: 93cm

[Technic Gearhead]

That's one BIG project!  I like the design and the color scheme except for maybe the red bits.  The tipper might look nice with some blue trim on it a la 8052 to tie it back to the rest of the model better.  Looks like you're having fun with it!  

[timslegos]

Wow the excavator is an interesting addition.  Nice design.

tim

[dandexter]

In my previous post I forgot to outline it's functions.

All 12 wheels drive
Front 4 and back 4 wheels steer
Independent wheel suspension
Fully operating excavator attachment, same movements as the 8043 set (minus driving)  
Tipper tray raises and lowers

6x XL PF motors for driving geared down 3:1
1x M PF motor for steering geared down  
2x M PF motors for raising/lowering the tipper
1x XL PL motor for operating the excavator    

I'll keep working on the design for a good few months now.  I don't have near enough money to buy the parts for this model now, as I just brought the parts I need for my other MOC truck.

Thanks, good idea with the blue trim along the tipper.  It looks much better.

Thanks, in the end I thought I would make something a bit different then the normal trucks.

Why is the scale off the excavator differend than the truck?

The excavator is only meant to be a small/medium one, similar to the one below.

However yes your right some of it isn't to scale.  I'll keep working it, its only my first version/attempt right now.

What i mean that de seats off both cabines must be at same scale
