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.

@ 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.  :thumbup:     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?   :look:

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.

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?

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...

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.
