I have to agree that it's pretty much a resounding no, as is the case with my other hobbies, which are even more obscure and misunderstood.
The only time I'm able to attract any female attention with R/C alone is when I do something rather insane, such as jumping a large scale over a creek or attempting double backflips with a Savage and a 6ft ramp. Even then, they're only drawn to it because of the 'Wow' factor, not as a result of an actual interest in the hobby. Otherwise, they tend to think that we're just a bunch of kids who failed to grow up and out of our toys. Maybe it's true, but I'd love to see most kids or even the average adult attempt to tune a nitro engine or program a brushless ESC.
In summary, I find R/C to be quite a social hobby with the 20+ person weekend bash/race sessions we hold at the local track, but it sure as hell isn't going to help you get some.
