After owning and building most brands made since 1983, I built my first contemporary Kyosho car recently (RB5 SP) and I have to agree, the fit, finish and quality control on this car is light years beyond that of Associated and Losi. I was pleasantly surprised with the build quality of the car and all of the pieces—machined aluminum, molded composite or plastic, and the overall fit of everything assembled.
I have 2 Associated conversions here on the shelf in the workshop, and the Kyosho is by far a nicer car than either of them.
I'll definitely own more Kyosho products in the future.
