Totally agree, they may not be the fastest but the quality and design from the late 80s and early 90s was the golden age of toy grade rc's. Everything toy-grade produced today is cheap and ugly, no creativity or passion. Its a great shame Taiyo do not exist anymore and Nikko has also gone down the cheap path and no longer produce the quality RCs from 80s and 90s.
