sounds like me.... i built a track for the dnano and we decided to start building them for sale since the mini-z track wasn't designed for dnano use. kyosho's tracks are excellent but i'm proud of what we did
*edit* - btw, epoch racers r ok but the technology that has gone into the dNano is waaaay beyond the epoch. unfortunately, the main site has no english and they don't seem to be in a rush to translate it... its like its their new baby but i can understand knowing what they're planning
