[LDD file] Tatra 8x8 chassis WIP

[HorcikDesigns]

Hi,

while waiting for my BL order I tried to make an Trial truck chassis ;)

Please check it for mistakes or some other bugs. (whether you want)

ha ! I just right clicked on that with my mouse hoping to spin the model round!

Thanks for sharing I've been engineering something similar in my mind

though I cannot access your link to the LDD it says that the folder is not yet public

Yes, its not public yet.

Sorry for the un-publicity of the file, hope it will be approved soon ;) It is still WIP chassis, waiting to be finished with non-digital bricks ;) (or by hand of another LDD builder :D)

What kind of suspension do you use? With shocks or suspension like this one: http://www.nico71.fr/tatra-t815-8x8/

I saw some links in the back so i was curious

The suspension could be shocks or leaf springs (like in original 8×8 Kolos, I think) or whatever one can imagine - it is not yet secified.

The suspension arms are inspired by Nico71's T815 ( http://www.nico71.fr/tatra-4x4-t815/ ) And the links are there to keep the arms straight, because they are not solid when it rolls forward or backward. ;)

Thoughts... The steering is fixed only by friction and axles are bound to slide away over time...Where is suspension? What motors will you use? I suggest you tuse use more than 1 MLA, forces on steering are really high when offroading.

Thanks. This is only digital test, where I have tested the dimensions, so the steering would be much improved in the non-digital version. Motors - as I wrote in the picture, there would be two 5292s (RC Buggy motor) powered by an external twin BB connected with car by wires (without IR). When I look back, I would also change the position get it lower of the motors gearbox (rectangle frame with 16t-s to 24tcrown gears), or substitute it with some wormgear-ed structure.

Thanks for ideas. ;)

Just had a look at it. The main frame is OK, only if i were you, you should place those buggymotor lower in the chassis. This way you can keep it compact and sturdy. I also recommand you to not use 8 teeth gears. (including the new ones)

Thanks, but the 8t-s are making the gear ratio that I want there. However, I know that they aren't so reliable as eg. 12t-s
