Posted August 2, 201410 yr As polled in this topic: http://www.eurobrick...showtopic=98386 Combining topic and video comments/results the lead advatage was tatra 8x8, so I started building it yesterday. Today its finished and this is the first teaser picture: More coming soon! Edited August 2, 201410 yr by Zblj
August 3, 201410 yr Author Here we go Lets start with the cab. I used a sliding axle so the doors slide out and open: The suspension is faithfull to the original and is quite flexible. The front 4 wheels use the springs which are placed sideways. The rear 4 wheels use the 9L links, which act as leaf springs. For steering I used an M motor with a worm gear and a 24 tooth gear. You can see the steering black links under the worm gear. You can also clearly see the front springs. A picture of the truck on our "newsih" grass: And here's a video with more details: Download the LXF here: http://www.brickshel...i_tatra_8x8.lxf A banana was injured during the filming process... It was good Edited August 3, 201410 yr by Zblj
August 3, 201410 yr I was hoping to see an AMG 6x6 but this turned out to be a great tatra dude! p.s. if you still feel bad about injuring a banana, maybe you should watch this... Edited August 3, 201410 yr by MrNumbskull13
August 3, 201410 yr Looking good! I'd like to build it, could you take a picture of the underside and one from the chassis without the bodywork? That would be nice! MrNumbskull13 - WTF! Edited August 3, 201410 yr by Black-Build
August 3, 201410 yr Awesome truck! Looks really good with great performance too! I really like the body design.
August 3, 201410 yr Author Looking good! I'd like to build it, could you take a picture of the underside and one from the chassis without the bodywork? That would be nice! MrNumbskull13 - WTF! Thats why I added the LDD file, you can see everything there Thanks guys! I am also quite suprised how great it goes with "only" one XL motor.
August 3, 201410 yr Very nice. ;) It was imposible to mount that leaf springs to the fron axles too? It would be more realistic, I think ;) (T. Kolos 8x8 had leafs both in front and back)
August 3, 201410 yr Like always, great work Some very nice features in the suspension and steering. The 9L link is a wonderful and simple solution for suspension. It look very light accept the brick build cab
August 3, 201410 yr Author Very nice. ;) It was imposible to mount that leaf springs to the fron axles too? It would be more realistic, I think ;) (T. Kolos 8x8 had leafs both in front and back) Yeah, but I didnt see a way to add it to the front suspension. Thanks!
August 3, 201410 yr I love how realistic it is at this scale. It looks like a lot of fun to drive! You know, you should also build the AMG 6x6 and see how it compares to its "big brother". Edited August 3, 201410 yr by Technyk32231
August 4, 201410 yr Author I love how realistic it is at this scale. It looks like a lot of fun to drive! You know, you should also build the AMG 6x6 and see how it compares to its "big brother". I have some plans.... The only thing is that I dont have enough of those wheels, have only 8...
August 4, 201410 yr If only it had diffs .... But it his the most perfect tatra chassis replica at this scale ever.... In the winter my 8455 and 8421 plus a brickink order no doubt, to make the chassis at least I keep coming back to it in ldd Edited August 4, 201410 yr by Rockbrick
August 4, 201410 yr Can I see the steering geometry?, is the best and the most difficult part to do for me. It is difficult that the steering can´t be affected by the suspension.
August 4, 201410 yr I see that you have the problem in your Tatra, when the suspension works the wheels change their steering angle. Just solve that problem and build a perfect steering is what I like of building Tatras. I know real Tatras haven´t got a perfect steering but I like to build it .

August 5, 201410 yr I've often wondered how Tatra suspension should go, and that in reality the cycle of the suspension does in fact change the steering angle slightly. Thanks for that vid! Awesome Tatra And numskull... I think you need to see someone No the guy in the video does! I was hoping to see an AMG 6x6 but this turned out to be a great tatra dude! p.s. if you still feel bad about injuring a banana, maybe you should watch this... When I found out this guy was Australian, I felt quite sad.... But yes this is off topic. Edited August 5, 201410 yr by Doc_Brown
August 5, 201410 yr I've often wondered how Tatra suspension should go, and that in reality the cycle of the suspension does in fact change the steering angle slightly. I spent hours watching tatra´s steering because I couldn´t understand how it works without turn wheels when the suspension works... at last I found that it is not a perfect steering because the trasmision shaft doesn´t allow to put the track rod correctly (real tatras). I solved the problem in my Tatras raising the transmission shaft above the track rod, you gain correctly steering but using more pieces and having worse trasmision (they were not truck trials).
