I, like most of you, have mostly given up on our LHS. It's a Hobbytown. Nice enough folks but they only have the basics I use. I am pretty sure they don't have a clue what control line or free flight models are. I order almost everything online now - just the way it is.
I think we all would love to go to a well stocked LHS with knowledgeable sales folks but there just aren't very many of us that like to do the model airplane thing anymore. Times are different now.
I am an avid cyclist. This same discussion comes up about the LBS. They have many of the same issues that LHS do. The big difference is no one knows how to work on their bike so they take it to the LBS for every sort of repair. The LBS makes a killing on repairs but thin margins on the bikes and accessories. When you add everything up, the folks working/owning a LBS or LHS just don't make a lot of money. That's why there are several successful mail order businesses - low overhead and lots of throughput. I wish it were different but it's not.
