kevin is right , when foam tire became one run tire it killed it for me. i was getting tires at a discount but still could not afford it. now i get a set of rubber tires and run 50 or 60 times on them. get a new set of rubbers and only go a tenth or two faster. and with brushless now we see all the old timers starting to come back and race because now they can compete with the younger faster guys. its great to see old friends that you havent raced with in a while and they are just as fast and just as competitive and haveing so much FUN doing so. rember why we all started racing TO HAVE FUN!!!!!
