Looks promising and it is the only way I can think of to legitimately get two more wheels for the/a B-Model onboard. :)

So will the B model have 6 wheels or will it have two spares?

[deehtha]

B-model will have 6 wheels. If I can figure out how to get a turntable onto the a-model, without cheating, I might try a 3-axle crane

[2LegoOrNot2Lego...]

Lovely so far!!!

[deehtha]

Some updates:

Increased wheel size from 56x25 to 62.4x20. This I also dropped the caster angle on the front suspension. This allowed me to widen and simplify the front suspension quite a bit. Current shocks are the soft LBG ones, but they are not holding the weight right now, so I am planning on switching to the older medium dark gray.

* engine & front suspension module

I also switched to small white panels on the hood which allowed me to shrink the hood area, giving me some room for a brush guard and headlights.

I still need to finish the front and rear body work as well as the interior. The rear suspension is almost done. The main chassis and spare tire/counter weights are not done yet.

Some more updates

Finished the front end

I dropped the brush guard, not something desert race trucks have

I switched to the hard yellow shocks. I also added a stop to keep tires from hitting the fenders

Steering and rear suspension is hooked up. Need to secure rear shocks and switch to hard ones. I also need to mount the spare tires and shorten the lower part of the chassis, and put in some sort of dashboard.

Gonna drop the 2 speed transmission, just not enough room. Not quite sure about the cabin steering wheel.

This is pretty cool. I'm amazed it fits in the 10000 cs limit. The styling looks very good. I like the little details like the raised center of the hood.

I'm curious about your v8, since I struggled quite a bit with it in my B-model

[deehtha]

It is based heavily on this http://www.eurobricks.com/forum/index.php?showtopic=109214

The supports for the shocks are mounted at the ends and on a 5l or 7l beam that runs through the camshaft. When I get home I will see if I can get some better pictures of it.

[ludov]

Ah, I forgot about that thread. I guess the smoothness is from using the cam pieces, instead of the part I had to use (from the A-model):

Anyway, keep going

[flyboy01]

great build! can't wait for more pics, hoping to reverse engineer it.

[Samer]

I like that white panel with "Technic". Send it to me after the contest

[deehtha]

I played with the front suspension geometry a little and hardened it up a little bit. It was so soft it would compress just from rolling along carpet.

Rear shock mounts are done. So far the soft LBG shocks provide reasonable stiffness, and replicate the sinking look of a trophy truck decently at this scale.

Spare tire mount is mostly done. Might find a way to tighten it down a little

I still need to clean up the rear and add an interior.

flyboy01: If there are any angles that would help you to recreate it, let me know and I will try to upload some photos.

Samer: Those stickers and panels came from 42000. You can see them on the sides of the front wing. Definitely, one of my favorite stickers.

[deehtha]

A Model is now complete. As soon as I can get some good light I will get some pictures.

The hood is a little longer than I had intended, but that is dictated by the engine.

There was some friction in the drivetrain that I figure out. The front shocks are attached to the engine with at the ends. I had put the cross section on the axle that holds the cylinder heads in place thinking this would keep things tight. Turns out that connection is not 100% legal. Turned the piece around and the friction went away. Also allowed me to remove the yellow half bushes and gave the truck a nice roll when turning. Without the yellow half bushes I can shrink the front end a full stud, but I really don't want to reengineer that part for the 10+ time.

I redesigned the rear shock mount/spare mount. I had to move the spare tires in and down 2 studs.

Simple cabin. I think I'm gonna swap the seat for blue. I only have that piece in yellow right now.

Found the pictures from version 1.

I started with the body, so I could get the dimensions right

First version of the front suspension. This was functional, but I made the mistake of trying to add caster angle to the suspension. Ground clearance ended up being just over 1 stud, and the bottom of the body hit the ground before the shocks were even halfway compressed

And finally the first version of the chassis with the engine mounted and hooked up to the rear wheels. Many issues with ground clearance and trying to get steering to line up.

[Krall]

Very nice A model.

I'm looking for more photos and B model in future;)

[Appie]

Nice model. I really like the dashboard and seats (colour is good imo).

[deehtha]

I had to spend a few hours at the hospital today, so I messed with LDD for the first time. There were a couple of spots where I could not get the pieces to line up perfectly and some pieces I could not find in the inventory. If someone wants to try to fix it that would be great.

Dismantled the truck and have begun the b-model.

All of my parts

I think it will be some sort of dune buggy/sand rail with a V4 engine.

Large versions of my final pictures for the A-Model can be found in my brickshelf folder as soon as it is available:

[muffinbrick]

So you finally won't make 6 wheeled vehicle for B-model?

[deehtha]

No, unfortunately I no longer leaning towards a 6 wheeler. Did try to make a dually, low ride, extended cab pickup. Couldn't get the rear axle sturdy enough

[deehtha]

I wasn't happy with how the buggy was turning out so I tried something different. So far it a mid-engined 6 wheeled something. All three axles will be pendular with the last 2 axles linked so the truck doesn't lean to one side. V8 engine connected to 1 wheel on each of the rear axles. I'm thinking this will either be a generic trial truck type vehicle or an airport rescue truck.

2 studs seems to be the maximum lift on either rear axle. All 4 tires are on the ground.

[2LegoOrNot2Lego...]

So far so good...haha...!!!

[deehtha]

Did some more work on my b model. After playing around with various types of suspension, I decided to drop suspension on axles 1 and 3. Each wheel on the middle axle is sitting on a backwards trailing arm with no shock, so that they are almost always in contact with the ground. The engine is mounted in the middle, with the front wheels being driven. The chassis is articulated between the last two axles.

I am thinking something like this for the bodywork, but in blue and white instead of green.

http://blog.hemmings.com/index.php/2010/03/03/march-military-campaign-the-most-powerful-wheeled-vehicle-in-the-world/

I am debating whether I should continue the articulation into the bodywork, or hide it under the body.

[deehtha]

I got some body work done on the b model. Right now the articulation on the rear axle is just the axle, the body work will be rigid.

The blue is a test of the fenders, to make sure I can clear the range of motion of the last two axles.

Here is a shot of the other side showing the body without the fenders.

I geared the steering down a little bit. It feels more responsive this way, and less like the Volvo Wheel loader. Still some work left to do.

I don't even really know what to call this, I don't have a plan. Maybe I will call it a futuristic 6-wheeled trial truck.

[deehtha]

Finished the b-model. This one went through many more design iterations than the Trophy Truck. One of the big problems I was having was with 7l beams. I had 4 which would have been plenty, but each one was in a different color.

B-model has a fake mini v8 which is driven by the front axle. The middle axle are trailing arm suspension and free wheeling. The rear axle is articulated and controlled by the black 12z bevel gear on top.

The louvres and closed height of the engine compartment are adjustable.

At the rear of the truck is a little bit of storage.

As soon as I get some better light I will shoot better pictures.
