Mini-Mac seems like a great ides, but by todays standard, the 60/90 rule seems too small. I see virtually no Mini-Mac contests in the schedule. If the Mini-Mac rules were changed to allow up 72" or maybe even 80" airplanes, with no engine restriction, would people be interested? I sure would be. Or, is IMAC really about flying large and there's no particular need for Mini-Mac?
