Hi! Very nice Tatra, especially the idea with suspension, which is not holding on the axle. +1 for that
Its so good to see an european truck built by you from Japan :)
But, as everyone said only good things, I need to say some negatives about your model:
Real Tatra is much lower - especially between the cabin and wheels - This looks more like a mix of T815 a T813
Maybe It is beacause of using portal hubs, which are not used in 813.
The suspension is not made like that, I suppose you know that, but if you use the solution closer to the real 813 like this :
It will be much simpler and you save a lot of space to hold'n'mount the Shock absorbers. The red "spring" does not have to work as a spring, but as a bridge.

However, from what I saw from the pictures, you used something like this:

This solution is used only on lighter trucks and most of the time on the front axle in 6x6.
Also, the last thing is the centre of the wheel - It rips my eyes, seeing such a good tatra with so ugly wheels. The unimog tires are not perfect, however, if you improve it with 6L dish + 3L pulley or something to hide the holes + 3 liftarm
It will look much better.
