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

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 :laugh: :thumbup:

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... :blush:

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

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

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?

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.

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.

How many actuators will it take? Big or small?

Four actuators, the same like on the excavator.

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.

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

Ok, i think new design is finished.

Here you can see the new steering and drivetrain system.

Complete chassis
Posted Image
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.
