Well, here is how they do it in Sacramento Ca. http://www.sacramento-rc-flyers.org/...aws/index.html
24 pilots racing once a month. There are more planes being built to enter the class as we speak. Because of the great response they are adding a 1/12th scale "Reno" warbird event>> http://www.sacramento-rc-flyers.org/...lonracers.html There are already aircraft being built for this and some manufactures are getting involved.
