The only hobby shop that is close to Carmel is Hobbytown. They are a little hard to find and are in the Castleton Mall area. I'm sure that you can find them on mapquest. They have very little in r/c boating. They have tons of plastic kits and trains. They also have a great deal of r/c cars and planes. It is a very big store. Their website is htindy.com . There is a Radio Shack that is a few blocks from the pond if you need them, also.
