This is my interview with the top driver in the country. He drives a Kyosho and he himself admits they are weak. But he also explains why they ate weaker and why he still sticks with Kyosho.

I am also a Kyosho driver. i havent broken much of the car but i can definitely say my TeamC and Mugen cars have experienced less breakage and my sworkz breaks more. TeamC was an absolute tank for me but the Kyosho is the only car I've kept because it is the easiest drive.
