I have never been intrigued with flying – in fact I get really frustrated with flying video games. But, I find watching these little airplanes and flying objects fascinating.
There are few places in the Bay Area for model airplane flying.
If you want to pursue this as a hobby you might want to join Bay R/C.
If you are like me a watch-only kind of person, your best chances to see the little flyers are at Baylands Park in Sunnyvale (parking is $6 from March to October). Rancho San Antonio also has a field for non-gas powered model airplanes. 
For those of you who like to get hands-on education, the Hiller Aviation Museum offers the Drone Plex. Each Saturday and Sunday from 10:30 am to 12 pm there are demonstrations; from 1 pm to 3 pm you can sign-up for the flight experience – (an extra $5 for 20 minutes; museum fee is $16 for adults and $11 for seniors and youth, 5-17 year olds, under 4 year olds are free). The museum also has flight simulators.
