My ideas are offered as is, and do not come with a manufacturers warranty. You take it off the lot, you own it. 
Heheh. Seriously though I'd gladly volunteer time and help maintaining the track, marshaling races, and hitting on the divorced moms of the kids that come to race, but I am not prepared to get involved with the business of operating an R/C track. It's not that I think it's a bad business idea it's that I'm just not that responsible a guy.
As for the mini-z racing I have no interest in that small a scale RC, and don't feel like investing in a car just because it may be the only game in town.
