I mean that kyosho didn't do something to make R4 famous. If he sponsored some more good drivers now R4 maybe had a very good presence (until then Only shimo can take some good results). Thats very disapointing. WE buy upgrade parts who costs like one more kit and we still can't make car faster. Other brands have 1.000 different setup from many drivers in their sites and anyone can try one of this setup. We have only one setup from shimo in Boss speed track. Hobby is not only mini-z and buggy.
