Decline of 1/12th scale? If anything it has been more on the rise these last few years. But when it was its biggest there were no RTR 1/12ths either. The Corally is almost an RTR in that the chassis is pre-assembled but not an RTR...and I believe Academy also tried one as well. I seriously doubt having an RTR 1/12th would make any sort of long term gains as most of the RTR crowd don't have the patience it takes to tune a 1/12th scale.
