Interesting concept, but don't think it'll go far. Reason being is that there are already many sites in these other disciples, some of course better then others. Speaking form experience, you might get some RC participation, but I wouldn't count on much from the Free Flighters, our premier site, the NFFS (National Free Flight Society) website languishes most of the time with an occasional flurry of posts. Allot of dead time. I'm not sure what it is, but I suspect its because the average age of FFers is higher (though I don't really know what it is) then CL or RC and allot of the guys just don't do computers.
