8x8 TrialTruck - From LDD to Real Model (Part2)

[MarkusOSX]

looks fantastic but arent 2XL motors a little too weak? those insane polish freaks usually use 4 buggy motors for their truck trial trucks!

also i find this 26sec videos pretty annoying. id prefer one long video that shows everything.

and why are you using 2 recivers? isnt it only steering + drive? or did i miss something?

keep up the fantastic work

Sadly i don´t have the buggy motors, but these would be also my first choice then. I thinx two XL Motors are not to weak, cause the transmission uses two wormgears, but we´ll see if it works or not.

I will make a "long" video, till all is fixed. Atm I´m changing the steering system, cause its definitely to weak.

As Kevinator said: "I believe he had to use two receivers because it needs two motor directions due to the layout of the driveline" <-- That´s right.

I guess there is some more to change or fix, but this happens time after time...

@ Kevinator: The MiniTruck based on my Design is awesome. Fantastic work.

Can you plz make a pic from the back and bottom for me

:D I am glad that you like it! I took some more pictures. I can't wait to see your awesome trial truck driving!

This is the underside of the chassis, you can see the rubber bands I used for suspension

Here is the top of the chassis

Another view

And a posing shot :)

[MarkusOSX]

This MiniTruck is really cool.

You´ve inspired me to make a smaller model

[Kevinatorrr]

Awesome :D inspiration begets inspiration haha. I haven't seen any model use those tires in a looong time

[Kevinatorrr]

Okay, last one! Haha

Now the technic man has his own toy :) too bad I only had two grey #3 connectors

[MarkusOSX]

Haha, this is soooo funny.

[Paul202]

Hey if you don't mind me asking, approximately how mcuh did all the parts cost when you ordered form Bricklink. I am looking to build an 4x4 truck, but I want to know how much it will cost. Also, what store did you order from?

[MarkusOSX]

Hi Paul202,

it´s hard to say how much all parts cost. Depends on some factors.

If you order only new parts (like me) you have to calculate between 200 - 300 € (if you need all parts). But i guess it will be much cheaper, if you have already some parts and order only used parts.

I came from germany, so I´ve ordered most of the parts from german shops like TBS or Magic Magnus for example.

I can´t tell you, what a 4x4 will cost, depends also on which parts you need and if you want new or used.

Okay, last one! Haha

I bet you can´t beat this size

Funny you should say, I did try something haha

[MarkusOSX]

Damn.... haha

[Kevinatorrr]

I can't make any smaller than this, and it is not quite right, so this is the last, sorry for jacking your thread so long

[MarkusOSX]

Ok, you´ve won

[rm8]

Hahaha:)))

[MarkusOSX]

Eat this...

[Kevinatorrr]

If only I didn't have to deal with physics ;)

[matias bendtsen]

Eat this...

build it with real bricks.

[Kevinatorrr]

build it with real bricks.

Haha. Mine's smaller anyway ;)

[MarkusOSX]

Ok, you've got the "smallest"..... haha

Back to Topic now.

I think I will redesign the Chassis a bit to use linear actuators for steering.

I've tried two different solutions now and none of them really satisfied me.

Will take a time to get the Truck finished.

[Kevinatorrr]

How many actuators will it take? Big or small?

[MarkusOSX]

Four actuators, the same like on the excavator.

[MarkusOSX]

OK, I´ll make the chassis completely new. I think the steering with the linear actuators will be very stable and tight.

This is how it´s look like:

And I also think about a drivetrain with lockable differential.

[Paul202]

Wouldn't linear actuator powered steering mean that it would take forever to turn?

Edited October 28, 2012 by Paul202

[MarkusOSX]

Sry, I don´t understand what you mean with "forever to turn".

Greetz Markus

[MarkusOSX]

Ok, i think new design is finished.

Here you can see the new steering and drivetrain system.

Complete chassis

Body is the same

New door for batterie access

In this version I need only one IR-receiver.

So I need to order some other parts, befor I can build it new.
