You cleverly knock Kyosho by pointing out an example involving a RTR version. In all my years of racing I have never seen multiple parts fly off any car in a crash so I guess that makes you the privilaged one.
Yes Kyosho is more expensive than the other brands but they are also the only ones that are made in Japan (the pro versions at least) and we all know the quality of Japanese products. The cost also comes from the fact that they don't exploit cheap labour from poorer countries.
