Tatra RC Models | Beskydy Kit Show 2012 Part2 | Remastered

Traditional model exhibition in Kopřivnice, Czech Republic involving plastic kits, radio controlled models and real trucks from the local famous Tatra factory.
First part of this video is devoted primarily to a beautiful scale model of Tatra 813 8x8 Kolos.

That TATRA 8x8 looks so real that can be used in a movie, great looking truck

[@cwx37]

yes, it is very realistic ;)

TO ANI MODEL NENI-TO JE PROSTE NADHERA-SUPER

i am always like (r c videos) 👌👌👌👌👌👌👌👌👌👌

Krásná V3S škoda že ty nápravy nejsou aspon trochu napodobenina,

[@cwx37]

Souhlasím ;) . Tehdá kolega vzal Tamyia nápravy a vůbec to neřešil. Ale pořád se portálovým nápravám ve čtrnáctině všichni vyhýbají, jak čert kříži. V desetině dnes už existují PV3S s realistickými portálovými nápravami.

great!What sound module you use?

[@cwx37]

sound module in which truck ;) ?

[@Meuh974]

👍

[@cwx37]

:) thanks

Hmmmmmm those engine sounds, it's like porn for the ears. Yummy....... Where's all the driver figures. That blue tatra better not have a head on collision with those 2 jerry cans in the front bumper , holy cow, what a place to put them. Lol Another great wee video man. 😀👍👍👍😀

Thanks for your nice comment, Mike :) . Driver figures: well, not many of us do had one ... but its getting better nowadays :) Light blue dump truck: actually this is the famous military truck Praga V3S, but you are very close with your "Tatra" guess. These vehicles were powered a Tatra air cooled diesel engines. And those jerry cans were really in this spot in reality too (there were more below the cabin etc.) - to be accessible faster ... the engine is under the cabin and the massive front bumper provides this location with "some" safety :) ... I guess no one was really thinking about driver's safety in the early 50's on a purely military truck ...

Ich verstehe nicht ganz wie die einzelnen Achsen bei den Tatra's funktionieren. Wenn sie z.B. über eine Kante oder eine Kuppe fahren und die vorderste Achse in der Luft ist warum drehen sich die Räder unten so extrem nach innen? Auch sehe ich keine Kardanwelle, nur so eine Art Tunnel von vorne bis hinten, sind darin die Kardanwellen und ist das dann nur ein Schutz für die Kardanwellen? Manchmal sieht es auch so aus wie wenn die Differentiale starr montiert wären, daß sie sich gar nicht mittig mit den Achsen mitbewegen, ich glaubte auch schon mal daß daraus die Antriebswellen kamen, kann das sein? Dann verstehe ich's ja noch weniger!

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 :) ).
