Most clubs are built and financed by the members and so usually they decied what type of racing they do. Off road / on road ect... abd this has given us the seperated view of the sport as it is today.
With the increase in interest in RC cars, and it is increasing! I think its time one of the manufacturers were convinced to support a purpose built RC car center that covers all aspects of the sport.
A facility would need to have...
a large track for 1/8th IC and large scale
A banked track around the outside for scale Nascar
A smaller track for 1/10th IC and electric
An off road area for different track layouts for 1/18th and 1/10th buggies and an assault course for Monster trucks
An indoor area for 1/10th electric and 1/12 carpet
And even a small Mini z are and maybe a slot car track!!
Radio fequency allocation might be a problem!!
The facility would be run on a commercial basis with cars to rent and have a large retail outlet.
I have dreamed of such a place for years and fill in the lottery tickets every week just in case........
