That’s Traxxas territory, not Tamiya.
Tamiya can be faulted for making ”plastic models that can be run as RC cars if you’re careful” but they certainly don’t lack realism.
Whereas the Slash is larger than 1/8th of the real thing (even when generously using the smallest measurement) but...
That’s a 1/14 scale truck.
The TT01 chassis is commonly used with sports car bodies and they are 1/10 scale but when you put a truck body on it it represents 1/14th of an actual truck.
