nope... don't sell RCP and don't plan to. i build the tracks in our shop and the rubber/foam/pvc is tested and proven to give a closer to real experience with tire compounds and car handling. i'm not only referring to their previous design, i'm also referring to the extensive investment they r making in building a track specific to the needs of dNaNo. btw, "dude" is a term of endearment where i come from
