After 25 years of supporting kyosho products and racing the rrr I couldn't wait for the r4 to come out so I bought one straight away and built it,have been to six race meets now and have not made it through the qualifiers in all of them and ended up racing the rrr,so now for the last two months the r4 sits stripped down on my bench and there it will stay until one day kyosho gets their act together and fixes all the issues witch you all know, I still don't see why I payed so much for the car and now have to go out and buy all the upgrades to fix the problems wich are kyosho's fault.so the best setup/performance gain for this car is to not use it and buy something else for the meentime.I give up.have bought a X-ray nt1...
Cheers.
