Mini 8x8 tatra trial truck

[Zerobricks]

This is a very small 8x8 trial truck. In order to make it this small I ditched normal steering and used skid steering instead.

It has independent suspension ona all wheels. I used rubber 1x2 beams for springa ction, which works great, but the mass must be low.

Drivelink uses 1:6 gearing from 2M motors:

Rear can be loaded with anything up to 200 grams

@ Zblj: My son and I are going to build your MOC by using the LDD "Building Guide Mode" and the Parts List from LDD Manager . We enjoy seeing your Technic LDD files. Does the small battery box carry a single 9V battery, like the ones used for smoke detectors? If so, how long can the 8x8 run on such a small battery?

[Zerobricks]

Well i used a duracell 9V block. I used the same battery box in the twister and it still runs good. So I think it should suffice for some 4-8 hours of fun. Remember to use PF extension cable and 2 pieces of ALU foil to make it work on this battery box.

Yes, I will follow your advice about the Aluminum Foil in accordance with your previous EB Post:

I apologize for my language, I am a foreigner.

I would like to build a similar vehicle, but have two different engines - PF XL and PF Med.

Use subtractor?

by Sariel

Do you have any ideas?

I think that the subtractor will just make the truck bigger, more complex and in the end it may be less powerfull because of all the gears. I would stick with 2 M motors...

Cool little truck!

I like to see your creations, thy always provide some innovative solution.

[Ayumi]

Zblj, my truck will be bigger and heavier. Apply the spring because my frame is made of bricks. Otherwise it was impossible to build a subtractor.

Soon I purchase PF Medium and build something lighter and easier.

Build another Tatra, with harder suspension and orginal battery box.

Great Idea, but my collection is small.

Just a little fix for those who built truck and have troubles with suspension:

New assembly left, old one right.
