The GRAVEYARD!!!
If you are talking about Mike's Hobby Shop in Carrollton off of I-35, then yes, I am familiar with them. That's where I get all of my stuff (if I don't get it online that is). Very nice shop and extremely nice and helpful people. I would have probably given up last summer without there help when I was first getting into this hobby.
I fly at the North Texas Aeromodelers club in Denton, TX. It's a bit of a drive, but they are the nicest people I've met before.
