Just do some Google, Yahoo, and any and every kind of search you can find. I've found these forums are just about as helpful, if not moreso.. as chats are carried all day via postings/threads.
As these "forums" are layed out.. you can pick and choose your topic, you can definately search your topic(within a forum, or site-wide, as well as member searches).. I suggest and encourage just reading and studying what ever your questions are, as they come up... and/or simply taking time to become familiar with these types of message-board sites. There's many many sites with this format ... for all sorts of hobbies/past-times/obsessions/etc.. These forums and sites have somewhat become a "go too" for alot of us.. and many hobby-relationships develop over the years.. theres some folks I've been reading well over 10yrs.. and getting some great info and instruction by following build-threads, product info, etc.. and just reading and interacting about others experience... not only that.. its like reading a new model magazine every day.. and alot of times.. in the threads.. its like just hanging out at the flying field..
How much chat you looking for?? haha.. Just post your stuff.. sit back with a cup of coffee and bottle of glue.. do some work on a plane... come back and check it out every 1/2hr or so.. or whatever....
And... look at that... we just chatted. Whatchyaknow!..
