that's a T815 ;) ... a hand build unique piece

That Tatra 813 8x8 is a hand built unique piece. However, IMO there are companies producing (not so polished) RC models of Tatra trucks.

yes, a camera, Meshroom, my 3D editor and a 3D printer...

thank you

To je, chová se velmi realisticky a i ozvučení je perfektní.

Děkuji, sice trochu poskakovala, ale taky se mi moc líbila

thank you

Thanks mate. Some glue and bolts are necessary to join the 3d-printed parts together. The prototype model is still not finished completely, some of the accessories needs to be printed and tested. I'll post another video once the model is completed.

a lot of photos and Meshroom

Awesome! Thank you!

Nein, das ist die richtige Groesse wie beim Original: kzbin.info/www/bejne/n3KZna2nrruel7c

The best way to understand the original Tatra chassis is here: kzbin.info/www/bejne/r3K7oJyJhrp2gMU Our RC models' chassis is modelled according to the real chassis, therefore our models behave correctly. And you are right - the differentials and the inter-axle tubes form one rigid (and non-twistable!) assembly. This has huge benefits in stiffness of the whole truck, less vibrations and bending transferred onto the superstructures and cargo. Classical rectangular truck frames never achieve this rigidity and comfort and speed of driving/transport.

@@cwx37 thank you for that. I looked at this and now i understand it better but i've never seen this or something in this way bevore. With the Tatra's it is more of a kind of independend wheel suspension, i think you get a higher ground clearance, but where are the speed differences between the individual wheels balanced, they don't have differentials and i always thought that continuous axles are much more stable and resilient? That's why all other manufacturers use continuous axles, or does Tatra have a kind of monopoly on the fact that no one else is allowed to build like this? If that is not the case and this would be so much better, more resilient or more stable, why don't all truck manufacturers build like this?

@@wernergatterer2953 This is a good question :) . AFAIK Tatra holds the patents for several design principles used in their chassis. But obviously others are allowed to build this "backbone chassis" as well - have a look at Pinzgauer ... and obviously some Chinese companies tried to copy it (unsuccessfully though with their low quality of production) Tatra chassis is not the universal solution to all problems though. There are great benefits - much higher transportation speed without damaging the truck or cargo - see a comparison between a new Tatra Phoenix and a new MAN: kzbin.info/www/bejne/mpu9mWmEi8ysbqM . Which truck would you choose for off-road operation? - much smoother ride over rough terrain - much greater stiffness of the whole truck - extended lifetime of drivetrain (as it is completely hidden inside the tubes) - and combined with the original Tatra air cooled engines you'd get a truck operational all over the world without additional changes. But: - the chassis is also heavier than a rectangular frame and a set of solid axles, esp. with larger trucks. - it is also not wide-spread, so most of service personal is unaware how to fix it. - most of European and North American trucks stay on paved roads thoughout their whole life span and on good quality roads the Tatra chassis is just uneconomical (extra weight and no need for all wheel drive with diff locks, even though with snow and ice on the road you'd give anything for a Tatra :) ).

@@cwx37 thank you.

Thank you, I'm glad you like it. There are other Land Rover Discovery models out there, but for me they just do not reflect the reality closely. My model is based on a 3d scan of a real car and I must say there are very complex shapes on it even though it might look like a simple "box" at the first look.

Thank you ... actually when my project is completely printed and tested, I'm planning to make the STL files available. However, it is not an easy print - just the roof takes 32 hours to print in sufficient quality :) .

@@cwx37 still a great job 👏 what is your plans for the interior 😀 🤔

After verifying, that the motor doesn't get hot even when climbing up hill for a long periods of time (I really don't want to scrub melted PLA from the motor :D ), the interior will be printed as well. It has been scanned already, but not modelled yet ;) .

Yes, thank you. When I started this project I didn't expect the model would drive so smooth - the soft tyres are the key feature. It is amazing how low tyre pressure helps driving in loose sand.
