Probably the largest hobby shop in the Georgia, North Carolina, and South Carolina area. Located in Cumming, Georgia, it's a bit of a drive from Columbia, SC. They bill themselves as the largest Drone and UAV supplier in the US. Also as aerial photography and Part 107 flight training specialists.
The store is not the easiest to find, but once there you'll find ample parking in the strip mall. Even though they seem to specialize in mail-order, they have quite a selection to browse through.
If you want a good selection of multi-rotor aircraft, this might be a good place to get your hands on one. The staff seemed knowledgeable and polite. Whether you're a FPV racer, amateur photographer, or just like flying these babies, this is the place to go. They have the largest selection of multi-rotors I've seen.
Hours are Monday-Friday, 0830 to 6 PM, 9-4 PM on Saturday.
