It's a good site on Facebook for RC boaters of all kinds although right now it seems to lean more towards nitro and gas boats. There doesn't seem to be much of a presence of FE boaters right now but you're still welcome to get in. The site has been growing like crazy with over 800 embers in just around 2 weeks. Yeah, I'm there a lot. There's an amazing amount of what I'd call experts in the hobby there offering lots of help. I had a problem there and still had members giving me replies after I already had the issue fixed but to me possibly helped out others too in case they run into the same situation.
I like to find things that aren't normally thought of as being able to be used on my boats. You'd be surprised at what you can find in a grocery store alone to do something with.
