Marvin,
If you are looking to start up a section under the BRCA for 1/8th Electric Offroad then you will need to get some form of Committee members together, a loop-hole free set of rules together (from experience!) and approach the BRCA.
The way that we (the Micro Section) did it was to approach a section of the BRCA, the 12th Circuit Section, and ask them to take us under their wing. They gladly did this and voted within their committee to action this.
If the Micro Section want to become a section within their own right then we will need to get this voted upon by the BRCA.
My advice would be to get some RELIABLE and enthusiastic peeps together, find your leader and elect him chairman, get someone who is good at writing a story to do your PRO work, find a treasurer (someone reliable and good with numbers), and find someone who is willing to run around like a crazy man to be your secretary.
Approach a BRCA section and put forwards your proposal. If they arent willing to take you under their wing then email the BRCA Secretary (Mick Hill) and ask his advice.
Oh, and remember that we do this for the love of the hobby/sport, but dont expect it to be plain sailing..
If you need anymore advice let me know
